1. The Field of the Invention
The present invention is directed generally to a system for enabling personal security and localization. More specifically, the present invention is directed to a system for enabling personal security that is coupled to a ubiquitous mobile device and a localization system not dependent on a Global Positioning System (GPS) network.
2. Background Art
Low cost mobile personal security monitoring devices have been typically limited to discrete devices that require additional package space for travel. These devices are often limited to simply performing the action of an audio or visual alarm if an event such as the opening of a hotel room door is detected. These monitoring devices also have typically required that human action be taken to call for help. These low cost devices have typically not made use of automated communication through network means to notify various parties for help based on preprogrammed parameters and Global Positioning System (GPS) coordinates. Such low cost personal security devices have not integrated multiple detection methods and aggregated monitoring sensors and devices, located both local and distant, into a convenient and small travel package. Further, they have not included the ability to aggregate additional monitoring devices and to form mesh networks of multiple personal security devices and peripherals through communication means, such as Near Field Communication (NFC), Bluetooth, Wi-Fi and other wireless communication means. They also were not able to aggregate distant monitoring devices through wireless communication to the internet and wireless communication to other devices from the internet to remote aggregated devices. Disclosed below are references in which one or more elements of the present invention may be disclosed but none of which disclose devices used for performing the functions of the present invention.
U.S. Pat. Pub. No. 20130033358 of Yamazaki et al. (hereinafter Yamazaki) discloses a system including at least one sender, and a beacon signal sent from the sender that is received by a portable terminal. In accordance with a sender ID included in the beacon signal, the portable terminal displays on an Liquid Crystal Display (LCD) a map image and a current position of the portable terminal or a user having the portable terminal, and displays on the LCD a guide image as for events or exhibition items in a predetermined place. The portable terminal stores state information included in the beacon signal for each sender (sender ID), and transmits or moves the state information to a central terminal at a predetermined timing. Yamazaki fails to disclose a case capable of physical coupling to a mobile device. Yamazaki further fails to disclose a means by which to detect a large motion or movement and guard against detecting vibrations which are to be ignored. This publication fails to include a mesh network in that senders/nodes do not relay information between each other but only to a portable terminal. Further, the portable terminals do not relay information between each other and are not able to relay information from one terminal to another and back to the central terminal. A mobile terminal is unable to communicate directly to the central terminal. Thus, if a portable terminal loses communication, it cannot relay through another portable terminal. Note also in this disclosure that vibration is used to detect that a sender or node has been moved from a stationary position. A notice of vibration or movement indicates that repositioning and recalibration of Yamazaki's portable terminal is required while the present invention includes senders or nodes that can be continuously moving (as not required to be stationary). Yamazaki fails to disclose localization methods.
U.S. Pat. Pub. No. 20130146661 of Melbrod et al. (hereinafter Melbrod) discloses embodiments of a smart phone casing and information exchange system which enables a user to carry a single system that merges the digital and telecommunications necessities of the individual with the personalized cards, membership accounts, consumer credit and/or medical insurance or health information in a single source protected both physically with a hardened case, and digitally with appropriate safeguards for electronic protection. Melbrod demonstrates the use of a smart phone case capable of storing information and safeguards for allowing certain information exchanges only. It does not however disclose a smart phone case having the tools and means for detecting large motions and movements, etc. Melbrod also fails to disclose localization methods.
U.S. Pat. Pub. No. 20110195753 of Mock et al. (hereinafter Mock) discloses a smart phone case with Light Emitting Diodes (LEDS). In a particular embodiment, the case includes a front portion adapted to cradle a lower portion of a smart phone, a rear portion adapted to engagingly mate with the front portion to secure the smart phone within the case, a first strip of LEDS and a second strip of LEDS that are mounted on opposing sides of the front portion, a vibrating sensor that is adapted to activate the LEDS of the case when a vibrator of the smart phone is vibrating, and circuitry is used to control the vibrating sensor and the LEDS. The vibrating sensor detects vibrations of the vibrator of the smart phone when the smart phone is receiving an incoming call or message. The LEDS are programmed to display in a set sequence when activated, where the set sequence to display the LEDS is selected by a user. Mock demonstrates the use of a case for detecting vibration from a smart phone and taking an action, i.e., activating LEDS based on the detection of the vibration. It does not however disclose a smart phone case having the tools and means for detecting large motion and movements, etc. Mock also fails to disclose localization methods.
Therefore, there arises a need for a mobile personal security system which can be seamlessly coupled with a ubiquitous mobile device for providing personal security and a localization system not dependent on a Global Positioning System (GPS) network at low costs.

In one embodiment, the synchronizing step is performed via a peer-to-peer arrangement. In another embodiment, the synchronizing step is performed via a web server arrangement.
In one embodiment, there is provided a mobile device case that itself can serve as a sensor module that can be removed from the phone and placed for security monitoring (e.g., it can be removed from the phone and with an attached lanyard hung from a room door to detect motion with an integrated accelerometer).
One embodiment of the present invention includes a mobile device case or mobile personal security device (MPSD) constructed so as to function as a mobile device case for devices such as mobile phones, tablets, and other mobile communication devices and peripheral devices thereof and the like. An MPSD may include one or more assembly modules and monitoring capabilities for use in conjunction with a mobile device or mobile communication device (MCD) such as a mobile phone, computer tablet and the like. The MPSD is constructed so as to be able to optionally include one or more sensors or Secure Linked Devices (SLD) that can be decoupled from wired and wireless connections to the MPSD and provide monitoring through a plurality of methods for sensor and other data input into the MPSD. This MPSD device may include, but not limited to, an MCD case having one or more integrated sensors such as an accelerometer and an attachment method such as a lanyard for attaching to a door handle or other object for the purpose of security monitoring. A mobile device case that is removable, functions not only as a proxy or data concentrator to external sensors, but also provides an optimized method of carrying or attaching those sensors for ease and simplicity of transport to a new location. In one embodiment, the present sensors can be attached to or detached by sliding into slots in the case or sliding off from the slots.
This system also functions as a mesh network allowing sensors to relay data to the mobile device or to the “smart case” with the smart case functioning as a proxy and data concentrator. Further, more than one mobile device can be securely paired to the system allowing multiple persons to receive and act upon the data (i.e., two parents, each monitoring children with sensor modules). Note that sensors in a mesh network can form subgroups to allow for, but not limited to, (a) data averaging; (b) focused monitoring such as extra listening sensors attached to a baby's crib to listen for breathing/movement from multiple directions (as a baby may be facing different directions). In one embodiment, this mesh network system is fully mobile and easily moved and set-up at a new location (e.g., a hotel room) as all components including MCDs are mobile.
In one embodiment, the present security system makes use of remote sensors to detect motion, relative distance, and direction of motion through the combination of synchronized clocks, an accelerometer, time of flight between devices and a mobile device (or smart case working as a proxy/data concentrator).
The present security system may not provide accurate location information but such information is suitable for a monitoring system that would provide these parameters for use in keeping a group of kids together, e.g., via sensors attached to each kid in a public venue. Often, in such applications, accurate distance measurements are unnecessary. In some embodiments, compass readings may be utilized to assist in making directional references for the system.
Practical application examples include, but not limited to the following:
(a) A sensor with a Radio Frequency (RF) receiver (Wi-Fi for example), an accelerometer, and its clock synchronized to a system (all devices in the system being synchronized when set-up at a new location) is attached to a door. The accelerometer detects motion and sends an initial alarm signal. The MPSD and/or MCD determines if the motion indicates low or high risk and takes actions based on the interpretation of the data (i.e., an extreme event indicating the door has likely been kicked-in or a small vibration likely due to air movement). As the initial motion has been detected, the second part of the security monitoring comes into play; the detection of relative motion, speed, and change in position of the sensor in order to determine if a security risk exists. This detection is made by comparing the time lapsed between sent and received signals between the MPSD and MCD to determine if there is a security risk. In the example above, only one accelerometer is used. This can lead to false interpretation of small vibrations of the door as low risk and likely just air movement. However, the small vibrations can be the result of an actual tampering of the door lock and slow opening of the door so as not to trigger a security risk assessment. In order to know more precisely if the door has been opened, there is a need for detecting a change in position of the sensor. This is accomplished by determining the time of flight of the signals between the MPSD on the door and the MCD. In this way, a door being tampered with (e.g., lock picked) and opened could be accurately identified and an alarm created. In another embodiment, comparisons of time stamps between the senders and receivers are used to indicate situations of concern.
(b) In a second example, a group of persons are monitored and kept together. For instance, a group of preteens on a field trip are monitored and kept together with two or more teachers. Each preteen can be in possession of a sensor module handed to them by a teacher. The teachers, each having a mobile device linked as part of the mesh network could monitor the relative distance (near, moderate, far), relative rate of travel (relative, not needing a unit reference, and low accuracy but as compared to others in the group), and relative direction of travel (again relative to the need with general direction and low level of accuracy needed).
(c) In a third example, the system could be set-up by placing sensors at stationary locations around a given vacant area where changes in the RF signal characteristics are monitored. Such changes could indicate changes in the time of flight of signals between devices and the possible presence of an intruder. The present system may seek new signals from devices that are not part of the security system indicating the presence of a new signal source that could be an intruder (e.g., a burglar with a cell phone or a remote control device and its new signal being identified as new to the monitored area). This is especially useful in that motion detection by tracking a heat source across zones, e.g., in a traditional security motion sensing situation, would not be necessary and temperature variations (e.g., due to forced air heating sources) in the air would not be a significant factor. Further, movement of non living objects would also be detected preventing remote control devices in possession of intruders from not being detected.
In one embodiment, an MPSD is constructed as a discrete device that can be worn on the body in the form of a MCD case that is worn similarly to a watch in that it attaches to a body limb or other body part and may be decoupled from the MCD providing remote monitoring through a plurality of wireless and wired communications. The MPSD can be coupled to a Brain-computer interface (BCI) and/or wired glove/dataglove/cyberglove” (connected or not to exosuit/Virtual Reality (VR) glasses/perception extension devices) to improve or help human capabilities.
In one embodiment, an MPSD functionality is integrated into a wristband (watch)/multiple body bands type (bodysuit) device/devices having a plurality of purposes such as, but not limited to, time monitoring, Global Positioning System (GPS) location, heart/oxygen/humidity/sugar levels/allergy monitoring worn through attachment to a body limb or other body part where this body device and body device extensions allow better conditions for human performance. This capability can be extended to use neurological observations to enable MPSD functionality to automatically administer life-saving treatment such as, but not limited to, applying insulin or cortisone injections. Also this can be used by older people to monitor their health and need for help and provide a way to communicate their needs to a central or multiple computers and networks in a home or other places.
Another embodiment of this invention is the integration of an MPSD into an MCD that is worn through attachment to a body limb similarly to a watch. This MPSD can be a device placed internally to a person's body such as a pacemaker. The MPSD/pacemaker can indicate that the person is in need of help and provide necessary assistance in an exosuit capability for elder people.
Another embodiment of this invention is one or more SLDs that may serve as a case for a MCD or MPSD that is worn in a similar fashion to a watch and attached to a body limb or other body part and may be decoupled from the MCD or MPSD.
Another embodiment of this invention is an MPSD or an MPSD integrated into an MCD that is integrated into a strap, rope, or band form that can be attached in a plurality of methods to a person or other objects and locations.
Another embodiment of this invention is an SLD integrated into a strap, rope, or band form that can be attached in a plurality of methods to a person or other objects and locations.
Another embodiment of this invention is an MPSD constructed so as to be a device with the general appearance of eye glasses.
Another embodiment of this invention is the integration of an MPSD into an MCD that is worn in the general fashion of eye glasses or other visual devices such as goggles including electronic and mechanical assemblies for a plurality of purposes.
Another embodiment of this invention is the integration of one or more SLDs that are worn in the general fashion of eye glasses or other visual devices such as goggles including electronic and mechanical assemblies for a plurality of purposes.
Another embodiment of this invention is an MPSD or an SLD constructed so as to be a device that can be easily concealed through appearing as an item of a different use such as, but not limited to, a button, clasp, or article of adornment such as jewelry.
Another embodiment of this invention is an MPSD, an MPSD integrated into an MCD or an SLD worn as a separate dangling device such as a keychain or keychain attachment in general appearing like a car key fob.
Another embodiment of this invention is an MPSD coupled to an article of clothing so as to provide added functionality such as heart monitoring in a shirt, rate of speed and distance in a shoe, camera observation through a hat, and other forms of data that would be useful for monitoring personal security.
Another embodiment of this MPSD includes one or more cameras that may work separately or in unison with the MCD camera to provide three dimensional (3D) video capture or pictures (this 3D combined with GPS (location information) information can be combined with an exosuit to provide help to elderly people for physical mobility and directional assistance. For example, a combination of robotic assistance and an exosuit/MPSD would allow humans to have a richer live during the elderly years. The capability to use sensory integration/MPSD can allow a better integration between humans and monitoring air and weather health conditions. For example, allergens could be monitored (e.g., pollens) as well as air quality hazards (e.g., pollution) to protect persons sensitive or simply wanting to avoid exposure. For personal security, some sensors in the MPSD system could detect dangerous substances (e.g., poisonous gasses) that can be dangerous and alert the individual and in some circumstances also provide a preventive mechanism such as a filter face mask. The user could view in 3D on the screen by each of two camera views being displayed on ½ of the screen and the case providing a visual divider between the screens when held close to the face of the user, much like looking though a stereo photograph viewer. This MPSD captured video or pictures could be activated by a preprogrammed sensor input or other input for a plurality of monitoring methods. In this way, the holder of the MPSD could also capture pertinent evidence when a disturbance has occurred as well as playback or stream the video or pictures in real time to third parties such as the police. The MPSD may optionally be incorporated into the MCD and function through the use of application software.
Another embodiment of an MPSD is a MCD case optionally including one or more cameras that may work separately or in unison with the MCD to utilize night vision techniques such as, but not limited to, night vision light emitted from an LED and made visible on the screen of the MCD. In this way the MPSD coupled with or separately can provide an emergency night vision device giving persons a better chance of escaping a dangerous situation by using the cover of darkness. The MPSD may optionally be incorporated into the MCD and function through the use of application software.
Another embodiment is an MPSD and/or an SLD as location devices that have their location determined through the use of time of flight measurement to one or more transmitter nodes allowing for its approximate location to be provided to third parties for location monitoring. In yet another embodiment, an MPSD is a location device that has its location determined through the use of signal triangulation allowing for its approximate location to be provided to third parties for location monitoring. More than one MPSD or SLD may be employed to receive and transmit a signal so that an averaging might be used when some signals may be very weak and difficult to use well. Transmitter nodes may be inside buildings such as, but not limited to, Wi-Fi transmitters or external to buildings such as, but not limited to, cellular towers. A smoothing algorithm may be employed to provide more stable time of flight reference. The smoothing algorithm yields smoother linear curves with less extreme vacillation which corresponds better with the actual MPSD/SLD motion. The movement of the MPSD/SLD out of a set of parameters such as, but not limited to, distance from one or more transmitter nodes could be used to trigger a plurality of alarms and methods to request help from third parties.
Another embodiment is a mobile system using time of flight location technology. The use of signal transmission between the MCD and one or more MPSD and one or more SDL would be used. All components of this system could travel easily to a new destination and be set-up into a temporary monitoring system as a new location such as a hotel room. The time of flight of signals between all devices would be measured and used to indicate movement and relative position between devices. For example, a change in a position of a SLD on a door relative to the MCD could cause an alarm (e.g., a person is sleeping in a hotel room with his smart phone (MCD) beside him) to sound an alarm in the MCD but also third party devices through preprogrammed responses (e.g., set-off a hotel alarm or call 911). Another example of use would be for a traveling parent holding a MCD to be able to monitor children having their own MCDs, MPSDs and/or SLD in their possession or attached to their persons. Relative position and likely distance could be monitored to keep a group together and if a member gets too far away to move in their direction to find them (e.g., a metal detector uses signal bounce to lead the user to the metal object, but in this case the seeking MCD uses monitoring of the time of flight of signals to get closer to the person or child holding another MCD, MPSD, or SLD). Further, this approach could be used to identify “good devices” that are known and “bad devices” that are unknown and could be intruders entering into a monitored area. In one use, the MCD could be removed and the MPSD and SLDs could continue to monitor and collect data such as within a hotel room. Upon request, or when a device is triggered, the MPSD and or SLD could provide a report of any changes in movement (e.g., a window or door) or the intrusion or an unknown signal into the monitoring area. The collected data could be provided to one or more MCDs and third parties through a plurality of communication links. For example, a smart phone could remotely access one or more MPSDs and or SLDs to get a security data report and use it to determine if the monitored area has had an intruder. Another example would be for a person outside his hotel room with a smart phone to use Bluetooth protocol to access one or more MPSD and or SLDs within the hotel room to determine if an intruder is present. This could be used in the same way with an automobile.
Any of the MCD, MPSD, or SLD may include a “Find Me” button or alarm functionality. That alarm functionality would employ a plurality of methods to call for help by sending automated alarms to third party monitoring to a call for help signal to another MCD or MPSD (or relayed through another SLD). For example, a mother could use the link between her MCD or MPSD to a SLD attached to her child to monitor distance, but the child could also push the “Find Me” button if they became lost or scared. The mother would receive the alarm and use positioning technologies (e.g., time of flight of signals, triangulation, etc.) to locate the lost child. A voice link could also be established between the MCD and the SLD to provide real time communication to facilitate faster location of the lost child.
An MCD, MPSD, and or SLD could be used as a beacon to allow for return to a given location. For example, in a beacon mode, an MPSD could be left in a given location (e.g., locked to a stationary object) and provide a beacon signal for later returning to the same location. The beacon mode would use a plurality of methods to secure against tampering while in beacon mode such as, but not limited to, fingerprint recognition. The beacon mode could allow others holding an MCD, MPSD, and SLD to return to the beacon at a set time, e.g., persons camping or in a store. Another way in which the beacon mode could be used would be for the holder of the designated beacon device to be able to actuate a “beacon signal” indicating to the holders of the other MCDs, MPSDs, and SLDs to come to the location of the designated beacon devise. For example, a chaperone for a teenager field trip could call the members of the group together when time to leave a given location.

The present methods and systems may be understood more readily by reference to the following detailed description of preferred embodiments and the examples included therein and to the figures and their previous and following description.
In order to eliminate false detection, the system must detect a motion warranting a response from the user in conjunction with the time of flight data indicating a distance change has occurred. A triggering of the accelerometer signals that a motion has been detected and a notification is sent from the mobile device case 2 to the mobile device 4. This event marks the start of the monitoring phase of the sequence. An initial alarm may be emitted to the user signaling the detection a motion has been detected in the mobile device case 2. Alternatively, the monitoring phase may start immediately after clock synchronization has completed. Upon detecting a motion with the accelerometer, a question remains as to whether or not the motion is caused by an action which warrants a response at either the mobile device 4 or the mobile device case 2. Upon receiving the notification from the mobile device case 2, the mobile device 4 initiates a process where one or more values of the time of flight are obtained. The process in getting a time of flight value is similar to the process in which a time of flight value is calculated in the calibration process. As the time of flight of a message corresponds the distance between the mobile device case 2 and the mobile device 4, a movement in the mobile device case 2 causes the time of flight of a message transmitted between the two changes. Therefore, a significant deviation of the time of flight from the average time of flight previously established in the calibration process may signal a large change in the position of the mobile device case 2 and an alarm may be triggered at the mobile device 4 to indicate such event. If an additional device, such as a sensor 6 or a mobile device case 2 were to be added to the network, clock synchronization may be performed to the entire network or to the newly added device alone. A request for clock synchronization may be initiated via the device to be added. In one embodiment, such request is actuated via a button functionally connected to such request. Although the example depicted in
In order to determine to a high degree of certainty that a large motion has indeed occurred, a quality check 40 including the following two quality checks may be performed.
An Example of a Quality Check for Confirming that a Movement has Begun
Just after the initial distance between devices is determined (first measurement after any calibration loop), the device can be disposed in a stand-by mode to conserve power. If the accelerometer detects a movement while in standby mode, the device having the accelerometer wakes up and starts to send time data such that time of flight (TOF) data can be calculated in the device receiving the time data. The accelerometer serves here to both provide a confirmation of movement and allow for a power conserving stand-by mode. In the event that environmental factors may give difficult signal readings (e.g., moving steel objects that could cause signal reflections that could falsely be interpreted as movement), such quality check can reduce extraneous or unreliable time data. The use of a standby mode allows for less power usage by only making transmissions when movement begins. It is important to note here that both devices in a two device system of a phone and a sensor could use sleep mode, but TOF calculations need to begin if either one of the two begins to move.
Examples of a Quality Check for when Devices are in Motion and are Regularly Making TOF Calculations
Scenario A: Accelerometers in both devices compare relative speed to each other.
Scenario B: Gyros in both devices compare relative angle of movement off of horizontal between both devices.
Scenario C: Compasses in both devices compare relative directional heading between both devices.
Scenarios A, B, and C contribute to helping to maintain good relative position between devices while TOF method continues to establish relative distance, especially for use when viewed on a mobile device screen with a grid reference. Note that compass and gyro are used only to assist in orientation as in quality check and they are used for screen display/interface and do not detract from TOF.

In this embodiment, the cost of operating both the frequency originator device and the frequency receiver device is minimal. Most of the energy consumption of the present system lies in the broadcast of signals from the frequency originator device. When compared to a conventional localization device, e.g., a GPS system which not only requires external signals, e.g., those of satellites and relay stations but also may succumb to inclement weather, the present localization system utilizes smaller amounts of resources. There is neither satellite infrastructure nor any third party fees required in the present systems. The present systems are self-contained system without requiring external fees for signal information, e.g., GPS. The present systems can be readily used at low costs as they utilize existing communication means in sending alarms or danger notices, e.g., over an internet, data, or text, connection that would already be a part of the mobile device owners services. In the present systems, additional monitoring fees are not required to notify the authorities as the systems that can directly call the police through the mobile device, e.g., mobile phone. The energy consumption in the frequency receiver device is minimal as compared to other means of localization. The present systems utilize low energy consuming technology, e.g., sound frequencies and as a result, the devices in the systems do not need to be powered by large amounts of on-board battery power, reducing the battery costs which constitute a significant total cost portion in any mobile device. As the present systems are readily movable, they can travel easily with their owner from one location to another, relieving the need for multiple systems at multiple locations. In any systems disclosed herein, a speaker that is built-in or external to a mobile device can be used as a frequency originator device while a microphone that is built-in or external to the mobile device can be used as a frequency receiver device. As these components are typically already bundled with a mobile device, e.g., cell phone, no additional equipment or costs are required. In terms of the processors of the present systems, high volume or mass produced mobile devices such as a cell phone or tablet, etc., are readily equipped with such parts. Although a cell phone or tablet is used for other purposes, such as personal communication, etc., a cell phone or tablet is available at a much lower cost than a lower volume central processing unit for a security system due to economy of scale in the case of the cell phone or tablet. Compared to existing localization systems designed primarily for use in an outdoor, unobstructed environment, the present systems function by utilizing signals coming from devices already in the system or that have traveled together at the same time into an enclosed location. The present systems therefore do not rely on an existing infrastructure in the building to provide a signal source or data (e.g., they do not rely on a Wi-Fi being present).
In determining the location of a frequency receiver device with respect to a frequency originator device of a known location, the following steps are taken. First, the distance between the frequency receiver device and the frequency originator device is determined. In one embodiment, this is achieved by first synchronizing a clock of the frequency originator device with a clock of the frequency originator device. Then a directional message containing a broadcast time at which the directional message is broadcasted from the frequency originator device at an orientation about an axis of rotation of the frequency originator device and received by the frequency receiver device. The time of flight of the directional message is obtained by calculating the difference between a receive time at which the directional message is received by the frequency receiver device and the broadcast time. The distance between the frequency originator device and the frequency receiver device is determined by multiplying the time of flight of the directional message by the speed of the directional message. This is followed by determining the frequency of the directional message and determining the orientation of the directional message with respect to the frequency originator device by looking up a table containing orientations of messages about the frequency originator device with respect to the frequency of the messages. The location of the frequency receiver device can then be calculated based on the orientation of the directional message and the known location of the frequency originator device. It shall be noted that the known location is movable. In other words, it is the relative positioning of the frequency receiver device and the frequency originator device that is important. For example, in an application where a frequency receiver device is configured to follow a frequency originator device at a distance, the frequency originator device may be in a moving state at all times, but the frequency receiver device must move with the frequency originator device to maintain a preprogrammed distance.
The following steps are taken in determining the location of a frequency receiver device with respect to at least two frequency originator devices where the location of each is known. In the embodiment shown in
A frequency originator device can be a mobile device and whenever possible, it is preferably connected to a wall power source such that its service is uninterrupted. A frequency receiver device is preferably a mobile device such that its use is not tethered to a fixed location. The present localization method may be extended for use with venues already having frequency originator devices, e.g., stadiums, subways, malls, parking lots, etc.
Interference may occur during transmission of data from one device to another. In order to avoid interference, a strategy that determines the most favorable frequency of a signal is used. In doing so, signals are transmitted at varying frequencies from a frequency originator device to a frequency receiver device at, e.g., regular intervals. The signal with the shortest time of flight is considered to be the signal having most suitable signal frequency as signals received at a longer time of flight may indicate the presence of echoes or other effects of interference. Upon determining the most suitable signal frequency, future communications between the frequency originator device and the frequency receiver device will then be made at this frequency to avoid interferences. The present systems are also capable of use underwater where GPS is unavailable. When used underwater, suitable water-proofing technologies shall be used to ensure readily available mobile devices which are typically designed for use in air do not get water intrusions.
Further disclosed below are two examples of mesh network which may be formed from the presently disclosed application adapted to a mobile device, mobile device case and/or a sensor. One example involves an assigned user (customer) location by description, but not a known location on a grid relative to other users while the other involves having a specific location of the customer relative to other users as determined by the use of a location method through the devices.
In this example, there is no specific location of the customer mobile device determined through any positioning system and there is only communication between the mobile device and a restaurant system (which utilizes SLDs to form a mesh network by Wi-Fi, etc.).
(1) Customer enters restaurant;
(2) Customer places mobile device near a Near Field Communication (NFC) pairing device, e.g., a pad on a counter with a sign. It should be noted that the NFC pairing device can be located anywhere and there can be multiples as part of a mesh network (e.g., there could be one at each table for a walk-in and “choose own table” style of restaurant). The pairing device could be an SLD handed to the customer, much like table ready pagers. In another embodiment, the pairing device does not include an NFC device, but rather devices involving other radio frequency (RF) signals such as Wi-Fi or Bluetooth. When a button is pushed, it provides a secure gateway into the restaurant system for the mobile device and stays coupled to the specific mobile device through its Media Access Control (MAC) address or a pairing process until such time later it is disconnected through options such as the next time the button is pushed or the mobile device is out of range for a given time limit;
(3) Customer mobile device is allowed into the restaurant network while in the restaurant with: (a) the notification of the availability of a table when a table becomes available and (b) the table assignment. It should be noted that the mesh network of the system allows the customers mobile device to be relayed through multiple communication nodes (e.g., SLDs in examples disclosed elsewhere herein that are placed as desired around the restaurant to assure good communication, i.e. around obstructions);
(4) While waiting for a table assignment or at any time the customer can place their drink and food order over the mobile device;
(5) After, (3b) and (4), above, the waitress (may be a virtual person) is sent the customers information with notice to provide service;
(6) The customer proceeds to the assigned table or sits down at a chosen table and inputs his/her table number into the mobile device;
(7) The customer is prompted on the mobile device to provide a confirmation (a screen button) that they are seated;
(8) When the customer is seated, the system prompts the customer to select his/her order, e.g., desired drinks and optionally the food (if not taken by a waiter directly);
(9) A server/waiter (may be an automated system) provides the drinks and food to the customer;
(10) When the customer desires refills to his/her drink or more services, he/she pushes a button on his/her mobile device and service is dispatched;
(11) At the end of the meal when the customer is ready to leave, the customer is prompted to either (a) confirm and make payment by using a preset payment information that was confirmed at time of NFC access to the restaurant system or Wi-Fi entered data in advance or (b) initiate a secondary NFC pairing to initiate payment or Wi-Fi entered data and make payment authorization;
(12) Customer is removed from the secure restaurant system after making payment to allow the customer to provide optionally service evaluation information;
(13) Customer is automatically removed from the system if a preset duration of time expires without a signal or communication from the customer device.
In this example, there is a specific location of the customer mobile device determined for the mobile device and the restaurant system utilizes SLD in a method to establish the customer mobile device location.
(1) Customer enters restaurant;
(2) Customer places mobile device near NFC pairing device, e.g., a pad on a counter with a sign. It should be noted that the NFC pairing device can be located anywhere and there can be multiples as part of a mesh network (e.g., there could be one at each table for a walk-in and “choose own table” style of restaurant).
(3) Customer mobile device is allowed into the restaurant network while in the restaurant with: (a) the notification of the availability of a table when a table becomes available and (b) the table assignment. It should be noted that the mesh network of the system allows the customers mobile device to be relayed through multiple communication nodes (e.g., SLDs in examples disclosed elsewhere herein that are placed as desired around the restaurant to assure good communication, i.e. around obstructions);
(4) After, (3b) and (4), above, the waitress (may be a virtual person) is sent the customers information with notice to provide service;
(5) The customer proceeds to the assigned table or sits down at a chosen table and the SLD at the table connects to the customer mobile device to confirm location and provide secure methods for communication and payment (e.g., via NFC);
(6) An alternative step to #5 above would be that the customer is given a traveling SLD (stays with them until returned at the end of the meal) once the customer's mobile device is securely linked to the restaurant system and when they arrive at the customer's table, the SLD communicates through close Frequency Response (FR) (e.g., NFC) methods, but not limited to, another SLD at the table to give notice that the customer is now at the table and initiates a call for service;
(7) When the customer is seated the system prompts the customer to select his/her order, e.g., desired drinks and optionally the food (if not taken by a waiter directly);
(8) A server/waiter (or may be an automated system) provides the drinks and food to the customer;
(9) When the customer desires refills to their drink or more services they push a button on his/her mobile device and service is dispatched;
(10) At the end of the meal when the customer is ready to leave, the customer is prompted to either (a) confirm and make payment by using a preset payment information that was confirmed at time of NFC access to the restaurant system or Wi-Fi entered data in advance or (b) initiate a secondary NFC pairing to initiate payment or Wi-Fi entered data and make payment authorization;
(11) Customer is removed from the secure restaurant system after payment prompting to give service evaluation information;
(12) Customer is automatically removed from the system if a preset duration of time expires without a signal or communication from the customer device.
In one embodiment, the present NFC technology is practiced according to Dhwani. Reference is made to a research paper titling “Dhwani: Secure Peer-to-Peer Acoustic NFC” by Microsoft at http://research.microsoft.com/apps/pubs/default.aspx?id=192134. Dhwani is a novel, acoustics-based NFC system that uses the microphone and speakers on mobile phones, thus eliminating the need for any specialized NFC hardware. A key feature of Dhwani is the Jam-Secure technique, which uses self-jamming coupled with self-interference cancellation at the receiver, to provide an information-theoretically secure communication channel between the devices. Experiments showed that Dhwani can achieve data rates of up to 2.4 Kbps, which is sufficient for most existing NFC applications. An NFC technology enables physically proximate devices to communicate over very short ranges in a peer-to-peer manner, without incurring the overhead of any complex network configuration effort. However, the adoption of NFC-enabled applications has been stymied by the low levels of penetration of NFC hardware.
The communication with the MPSD can be though direct wired coupling to the MCD or though remote communication using wireless communication such as, but not limited to, Near Field, Bluetooth, and Wi-Fi communication. This remote communication can be wholly wireless or involve one or more wired connections and internet communication, in a plurality of combinations thereof to allow for great distance to separate one or more paired MCDs and one or more MPSDs and one or more SLDs. SLD can have the meaning of a device electrically coupled or wirelessly coupled or paired to the MPSD or directly to any number of MCDs. The MPSD device can be electrically connected directly to the MCD while functioning as a MCD case, but can also be wholly or partially decoupled and retain communication with the MCD and aggregate devices through wireless and internet communication methods. However, pairing of SLDs directly to the MCD is also possible utilizing application software on the MCD and the MCD functioning as the MSPD. The present security system would also allow for more than one MCD pairing, including a plurality of MCDs. MPSDs, SLDs, other computing and communication devices such as personal computers and servers can be paired to comprise one or more mesh networks or linked mesh network of devices. For example, the pairing of two mobile phones to one or more MPSD and/or SLDs could enable each paired mobile phone or device, when given an alarm code from the MPSD or LMD, to initiate separate and different automated commands. For example, one mobile phone could send an automated text to a friend while the other could make an automated call to an emergency number (such as 911) with a preprogrammed message having the name of the person and asking the police to locate the person by the GPS coordinates, network triangulation method, or other forms of geographic locating that may be used to extrapolate a location. Also embodied in this invention is an MCD using an wired or wireless connection to the internet making use of a soft phone (not needing a wireless phone service) to call for help or dispatch the police. Such a call, whether over a wireless network, mobile phone, or other method could be made without visible notification appearing on the MCD to prevent any assailant from knowing it was taking place. This would be especially beneficial if an assailant forced entry into a person's hotel room before the person could attempt to call an emergency number. The MPSD would be alerted during the initial stage of the forced entry through sensor readings of, but not limited to, motion, sound, etc., and would immediately call the emergency number covertly and in silence without the assailant knowing, giving vital time for the authorities to be notified and to respond without alerting the assailant of their dispatch.
One method of monitoring used by the MPSD is data provided from a linked network such as, but not limited to, a network providing information such as connected device usage that could indicate the presence of an unauthorized person while the owner is away. For example, the network may provide information over the internet that a device has been used during a period where the premise should have been unoccupied. Also the MPSD could connect to the network, but not limited to, network while still outside the premise and determine if there had been or still is an intruder based on information such as, but not limited to, electronics use by opening a refrigerator or turning on lights.
One monitoring method used in the security device is a motion sensor such as, but not limited to, an accelerometer, that when in use with a lanyard or a plurality of other attachment methods could be hung from a hotel door knob and communicate wirelessly to a MCD. The MPSD could detach from the phone as a removable MCD case and/or attachment and hung from the door. One or more SLDs could be removed from the MPSD and paired with the MPSD. The flexibility to position SLDs in a plurality of locations affords the best positioning for security monitoring purposes.
Another monitoring method used in the MPSD is a sound sensor to detect specific sounds such as the breaking of glass. However, this sound sensor could also be used as a listening device located remotely from the MCD, but communicating with the MCD through both wireless and internet communications. The sound sensor could utilize, but not limited to, voice recognition to sound an alarm or initiate actions based on the sound of a specific voice, the tone of voices, or the use of key words that are linked to preprogrammed or derived actions by artificial intelligence.
Another monitoring method used by the MPSD is one or more cameras for use in detecting, but not limited to, motion, as other parameters such as inferred light and light surges may be monitored. The mobile security device may have one camera that when paired with the phone can perform stereo or 3D video and photo function allowing for monitoring of change in distances (such as if pointed toward a door and the door opened). The mobile security device optionally may include more than one camera allowing for the device to remotely monitor, but not limited to, changes in distances when separated from the phone, thereby not requiring the use of the phone's camera to perform the monitoring function. The one or more cameras may also optionally be used to provide the remote transmission of live video or individual digital photos to the phone or directly to a communications hub and over the internet.
Another monitoring method used by a MPSD is GPS location monitoring and transmission of position to third parties through wireless or internet communication means. The GPS location information can be obtained through the GPS function of the MCD and when the MPSD is activated, the MCD is used to contact third parties and provide the GPS location of the phone.
Another monitoring method used by the MPSD is network tower location monitoring and transmission of position to third parties through wireless or internet communication means. The network tower location information can be obtained through tower location information provided by the wireless provider of the MCD and when the security device is activated, the MCD is used to contact third parties and provide the nearest network tower location to the MCD.
Another monitoring method used by the MPSD is network tower location triangulation by measurement of time of flight between network towers near the MCD and transmission of position to third parties through wireless or internet communication means. The network tower location information can be obtained through tower location information provided by the wireless provider of the MCD and when the security device is activated, the MCD is used to contact third parties and provide the estimated location of the MCD based on time of flight of signals to surrounding towers.
Another monitoring method used by the MPSD is local network locating such as an identified link to a Wi-Fi network and transmission of position to third parties through wireless or internet communication means. When the security device is activated, the MCD is used to contact third parties and provide pertinent information to identify the physical location of the local network to which the MCD has been either connected or identified if no connection was made.
Another function of the MPSD is to allow for emergency band transmission. This emergency band transmitter could be incorporated into the device or activate a transmitter paired with the device.
Pairing of the MCD to MPSDs and SLDs may be performed optionally with NFC communication when set to pair and moved into NFC communication range.
Pairing of the MCD to MPSDs and SLDs may be performed optionally with a combination of motions (e.g., two quick bumps between devices) and near proximity allowing NFC communication to confirm the simultaneous motion of the two devices to allow secure pairing.
Pairing of the MCD to MPSDs and SLDs may be performed optionally with Wi-Fi or other wireless or wired communication when set to pair and identifying the device to be paired as present on the Wi-Fi, wired, or other communication network or more simply with a combination of motions (e.g., two quick bumps between devices) occurring simultaneously by the two devices being bumped together.
Pairing of the MCD to MPSDs and SLDs may be performed optionally with Wi-Fi or other wireless or wired communication when set to pair and identifying the device to be paired as present on the Wi-Fi, wired, or other communication network with a combination of simultaneous motions (e.g., two quick bumps between devices to be paired) occurring simultaneously, or within a time interval acceptable to be viewed as simultaneous, allowing for network lag.
Pairing of the MCD to MPSDs and SLDs may be performed optionally with a combination of various communication methods allowing identification of the devices to be paired over a plurality of wireless and internet connections and optionally may include the use of a secure identifier such as a system generated number utilizing an algorithm unique to the authorized party or parties and their devices.
Multiple MPSDs and SLDs may also be paired into subgroups within a network or mesh network. This allows for multiple sensor capturing and analysis. For example the detection of vibration could be analyzed with data from one subgroup of sensors and compared to another subgroup of sensors to determine what type of vibration is taking place. A personal security device might more accurately then determine if an earthquake is taking place as compared to a more local shaking of a building from passing truck traffic.
Multiple MPSDs and SLDs may be paired into macro groups based on proximity or other parameter such as social category and for the purpose of sharing data and communicating with others included in the macro group. Connectivity would be more limited with macro group devices than for in-group fully paired devices to assure security. The macro group, for example, could be initiated simply by walking into a store and within proximity to other MCDs or on the same wireless network. An example of a security application would be a missing child in the store and the parent's immediate ability to send and instant message or text to all connected persons in the macro group with a picture of the missing child and a current description of the clothes being worn. Such real time communication could also warn of a dangerous or unknown person in the neighborhood and alert all the neighbors who are a part of the relevant macro group.
The MPSDs and SLDs may be paired with existing security devices that may be stationary at a hotel or in a home. This ability to pair with devices already installed allows for an expansion of the MPSD and SLD security coverage. Further this functionality allows for ease of the use by having a known security user interface that travels with the user and for which they have their personalized security settings.
The MPSDs may be powered with various methods such as, but not limited to, disposable batteries, rechargeable batteries, wired connection to a power source, and solar cells.
Another monitoring method of the MPSD is to allow the MPSD or separately SLD to operate autonomously without a direct communications link to the MCD or MDCs. For example, one or more MPSDs by themselves in combination with SLDs or SLDs by themselves could be left in a location to record monitored data and prepare information or warnings as soon as communication with the paired MCD/s or MPSD/s is restored. This can be done due to a loss of communication or purposefully where monitoring and advance warning is desired, but no method of communication exists (e.g., internet or wireless) to relay information to the MCD without the MCD being preset. An example would be the set-up of the MPSD/s and/or SLDs to monitor the inside of building, room, or vehicle and give warning to the holder of the MCD or MPSD before entering that a security risk has been detected. This would be accomplished by the MPSD/s and/or SLDs linking to the MCD upon entering communication range and transmitting data for a warning and potentially taking other preprogrammed actions such as calling the police. Another example of this functionality would be the MCD or MPSD being able to link to one or more cameras prepositioned inside a premise and able to be used for real time or playback functions allowing a person to remotely view the premise prior to entering. The MPSD and SLDs can function in a sleep mode or make use of lower energy Bluetooth to conserve energy and extend battery life.
Another method of monitoring use by the MPSD is to pair with systems in a car either wireless or wired and to utilize that data for personal security and safety. For example, the MPSD can receive information from the car crash sensors or airbag deployment and immediately send an emergency call for help to third parties providing such data as GPS or other derived location information and other pertinent information for emergency response including any real time health condition information that may be provided by the MPSD such as pulse, breathing, depending on optional monitoring functions included in the MPSD. Another example could be the MPSD or LSD receiving data from the car's rear facing camera while being tailgated and storing that information on-board to a remote location for use later if the event a rear-end accident or other type of accident occurred.
Another method of monitoring used by the MPSD is to have an in-transit (or in-car) mode that is activated manually or automatically by detection of the car system allowing for additional monitoring and preprogrammed actions such as the use of an accelerometer to detect a crash event and immediately send an emergency call for help to third parties providing such data as GPS or other derived location information and other pertinent information for emergency response including any real time health condition information that may be provided by the MPSD such as pulse, breathing, depending on optional monitoring functions included.
Another method of monitoring is the use of paired MPSDs or SLDs to monitor the movement of each relative to the others. For example, a parent in a store could know where their children are located based on the locations of their MCDs or integrated MPSD and MCD or the position of SLDs that are attached or in the possession of the child.
Another method of monitoring is combining the MPSD and Closed Circuit Televisions (CCTV) cameras to provide round-the-clock security. This could allow an individual to be under protective surveillance. The MPSD can be paired with the CCTV and the individual can, for example, do a specific gesture that indicates the need for help.
Another method of monitoring is using the MPSD with more than one integrated communication device that allows alternative communication in case a communication frequency is blocked. For example the pairing with the CCTV could be blocked for Wi-Fi but the Bluetooth could still reach the CCTV network and use an audio message from the individual.
Another method of monitoring is to examine the Electromagnetic Interference (EMI) that most consumer electronic appliances produce as identifying signatures.
The MPSDs and SLDs may have a panic feature that allows for taking multiple automated actions to contact help based on preprogrammed functions. The panic feature may be embodied in the form of a physical button that when held down for a longer duration initiates the panic actions. However, the panic function may be initiated with any number of methods including any of the actions such as a specified number of shakes, a code word said while pushing a button, or a failure to provide the correct response to an automated query. The panic response may include, but not limited to, the use of the MCD making loud noises, the noise of a paired device with a speaker serving as a siren, the initiation of a plurality of sounds lights such as those pared to the device or receptive to panic commands. A further embodiment of the panic functionality is to optionally have the panic feature send an immediate panic “electronic scream” instant message, text or other form of urgent notice to phones immediately in the area or connected to the same local network (e.g., a Wi-Fi). However the “electronic scream” may also be transmitted by wireless communication and internet communication to remote third parties. Another example may be the use of a MPSD or SLD panic function when paired with a car to set-off the car alarm siren and flashing lights. An SLD, for example, could be in the form of a key fob and similar in appearance to the car's key fob, but having the ability to initiate many more panic functions through the preprogrammed parameters in the MPSD system.
The MPSDs and SLDs may have a “go dark” command where a command is sent remove the risk of exposure of being found. Such “go dark” command may be, but not limited to, disconnecting from all communication network, unpairing with any local or distant devices, and turning off any GPS or other location capable technology. In this manner, the user/s of such devices can avoid any monitoring that may be intended to determine their location.
The MPSDs and SLDs may also have a switch to allow for information sharing to be at more than one preset level such as a company or work setting and a separate personal setting. The switch may be in the form of a soft switch or a physical switch. This allows for preset parameters in the MCD to only show one set of information such as for work and limit to not show information or provide data that is more personal in nature.
The MPSDs and SLDs can also have a “wipe clean” command that allows the device to be reset and delete any remaining data as well as initiate similar actions in any paired devices including the MCD.
The MPSDs and SLDs may have an emergency professional function that when an accident or recognized dangerous health event (such as a heart attack) occurs, the MPSDs or SLDs or both can utilize audio, visual, and wireless communication to notify the emergency professional of important medial information such as emergency contacts, allergies, etc. For example, the MPSD may send a text of information to any nearby emergency professional. The MPSDs or SLDs may give and repeat the information by playing a pre-recorded statement or text to voice data loudly and repeatedly to assure notice. The MPSD and SLDs may also utilize the MCD screen to flash hazard lights (e.g., red and white off and on) or display the information that has been pre-selected by the owner of the device.
The MPSDs and SLDs may be utilized to monitor heath status of persons as well. For example, an SLD could be a heart rate or pulse monitor coupled wirelessly to the MPSD and able to sound an alarm if the heart rate drops and to additionally contact third parties for assistance through a plurality of communication methods.
The MPSDs and SLDs may link to external databases and use processing power from external systems to provide high level device security to prevent unauthorized tampering. For example, the MPSDs and SLDs may utilize technology such as facial recognition where the software to run the actual analysis and the data for the facial recognition may best reside on a remote computer or server allowing the MPSDs or SLDs to minimize processing hardware such as processors and memory, keeping the cost low. Data may optionally be stored at a remote location and be transmitted real time, but may also be sending in data packs to best utilize communication power. The transmission of data packs also allows for the storage of information until such time as a network communication for the task is available preventing loss of data and efficient use of network resources.
The MPSDs and SLDs may send data for storage on a remote computer or server through wired or wireless connection to the internet, allowing the MPSDs and SLDs to have relatively low levels of on-board memory, keeping costs down. The data can be sent real time or at time intervals or copied to one or more other storage devices simultaneously.
The MPSDs and SLDs may function as secure keyboards coupled with encryption technology such as Bluetooth encryption controlling hotel devices. In this manner, keyboards that may be hacked, such as at a hotel, can be avoided. These keyboards could be used, in combination with MPSDs, with one or many communication devices to activate preprogrammed or new functionality via the keyboards. For example, a door or sensor could be enabled or disabled using the keyboard by a wife while a husband is using the phone paired with the door or sensor in a different location. This door or sensor will activate a security pre-alarm system in the web site and the wife will have a specific period of time to disable the alarm (also a key word could be used to present a dual possibility a real disable alarm and a fake disable alarm to protect the users).
The MPSDs and SLDs can be used as Bluetooth remotes, providing for secure and encrypted controlling of devices that may be hacked in locations such as hotels and other places where electronics may have a higher risk of having been hacked. However, the reach of the remotes can be extended by utilizing, for example, an SLD to send the Bluetooth command, while having the SLD receive its command from the MPSD or MCD linked through a larger area network such as the wireless telephone network or in combination with the wireless phone communication network, Wi-Fi, and internet connections.
The MPSDs and/or SLDs can be programmed with sleep mode and automatic shutoff functionality to optionally allow for time periods to not be monitored, periods of heightened monitoring, and combinations thereof.
The MPSDs and SLDs may be secured using facial recognition only or a combination of facial recognition with facial movement or other actions, including but not limited to, involving button combination pushes, screen or phone tap combinations detected by an accelerometer on-board to the MPSD or MCD.
The MPSDs and SLDs may be secured using voice recognition only or in combination with other device securing methods.
The MPSDs and SLDs may be secured using verbally spoken code words. In order to gain access to a secured MPSD or SLD, a background sound may be required (e.g., a song) and if the background sound is deemed incorrect, a silent alarm/help notification is initiated.
The MPSDs and SLDs may be secured using finger print technology only or in combination with other device security methods.
The MPSDs and SLDs may be secured using eye or iris recognition technology.
The MPSDs and SLDs may be secured by using eye tracking technology.
The MPSDs and SLDs may be secured by using photographic comparison, e.g., a face recognition for activation could also require a specific background to be valid and, if the background is incorrect, a silent alarm/help notification is initiated.
The MPSDs and SLDs may be secured using signature recognition technology.
The MPSDs and SLDs may be secured using visual motion detection such as movements or gestures recognized through an on-board or linked camera.
The MPSDs and SLDs may be secured using motion sensing technologies, e.g., motions that can be detected and interpreted. For example, the movement of the device in a
The present MPSDs and SLDs can include the functionality to do repeat automated security checks at specified times (or as an automated response to a security event). These security checks could be activated by the MPSDs or SLDs or from an external system that is securely linked to the MPSDs or SLDs. For example, the security check could be comprised of a phone call or instant message requiring the correct verbal or written answer which if not received would result in the monitoring system to contact third parties to request assistance. This would be especially useful in situations where privacy is desired, but having security monitoring is beneficial such as a first date situation or a person has a higher risk to encounter a dangerous situation. Any one of the aforementioned methods to secure the MPSDs or SLDs, is an embodiment of communication and confirmation techniques used to perform the repeat automated security checks and requires an action that when done correctly, gives an all-clear direction until the next scheduled automated security check. When done incorrectly, the MPSDs or SLDs will covertly or if desired, overtly notify third parties of the need for assistance to be provide to the person or persons being monitored.
Another method of monitoring used by the MPSD is Radar band motion and distance sensing. Radar signals emitted from the device or an external paired or unpaired device can be monitored to determine if there is motion or utilized to avoid obstacles on a moving MPSD or SLD.
Another method of monitoring used by the MPSD is temperature sensing. This temperature sensing can be utilized to determine if there is a danger of fire and contact third parties for help (such as by placing an automated 911 call). Temperature sensing could also be used to monitor health conditions of the persons to whom the sensor/s are attached. For example, the presence of a high fever could be caught immediately and a notice given to the person with the fever, but also to contact third party health professionals to provide assistance. This would be especially true for monitoring the temperature of a baby while the baby is sick and providing information to the parent.
Another method of monitoring involves heart rate monitoring. A heart rate monitor can be used to determine if a person is in duress and trigger an automated security check, which if not answered, can result in an automated request for assistance from third party emergency professionals or the police.
Another method of monitoring is blood insulin monitor receiving input through various methods and providing communication as outlined above and also through a plurality of methods including, but not limited to, and glucose meter module or integrated subassembly of the device.
Another functionality of the device would be to allow for wireless locking and unlocking of a door with the plurality of local and distant communications links outlined above. For example, a person could be remote in another city, connected to the internet, and send a signal through a network to the device while the device is hanging from the door knob by a lanyard at a hotel and allow the hotel room door to unlock, giving permission to persons while not having to be present. Additionally this functionality could be used to allow one mobile phone to relay necessary door access codes/data to another phone (that is paired earlier as a second phone with the device) and allow that second phone to lock or unlock the door. In this way, a person arriving at a later time could already have the hotel room door access information and be able to enter the room without the original person being present with their phone. The second person would not need to present at the hotel desk to request access to the room and have the possible issues related to not being the registered person for the room.
In yet another usage example, an exosuit/bodysuit can be used for the house to detect the user's location and temperature or health condition. This allows temperature sensors in the house to signal a security alarm in case an unregistered heat signature movement is presented close to the user. This sensor located in the bodysuit/exosuit can provide an early alarm system.
Bracelets with embedded MPSD configured for fingers movement detection can be used to control a mobile device and communicate for a voice impaired persons. The bracelets can be used as a virtual keyboard or/and extension to communicate to a mobile device or any other device with the MPSD interface.
Several MPSDs (having audio, video, GPS functions, etc.) can provide an extensive database about an individual that can use a plurality of data mining practices to create personal assistants, anticipating what the user needs before he or she may ask for it. For example, reminding a user to buy bread next time he or she stops for groceries. This could be an enhanced combination of services to provide a quick and easy answer to anything that the user needs, e.g., a movie that he or she likes. An MPSD combined with the personal assistance features could communicate with the movie network and make the arrangements via a social networking site without the user needing to look for the tickets or contact his or her friends.
