In exemplary embodiments, the light emitted will reflect off the wall or other surface to which the apparatus 100 is mounted, casting a glow around the apparatus and allowing it to be seen from essentially all viewing angles, for example, up to about 180 degrees. In exemplary embodiments, viewing angles of greater than 180 degrees are possible, such as where the apparatus is mounted on an angle on or in a corner edge of a wall, thus enabling viewing down two hallways that are at generally right angles to each other.
The face plate 310 may have an opening 332 to accommodate a display device 334, the display device 334 being as described hereinabove for display device 80. The face plate 310 has sides 336 that form a recess 338 that can accommodate the PC board 330.
The back plate 320 has top, bottom, left and right sides 340, 342, 344 and 346 that are made of a transparent or translucent material. At least one, and, in exemplary embodiments, a plurality of, light-emitting devices 350, such as, but not limited to, LEDs, are mounted to or associated with at least one of the back plate sides. In exemplary embodiments, the LEDs may on a strip of material and be electrically connected to a controller on the PC board 330.
In exemplary embodiments, the apparatus as described herein may also include an audible alert, such as an audio speaker or tone generator associated with the PC board that can be actuated when the light-emitting devices are actuated.
For the various exemplary embodiments described herein, the controller can be programmed so that the light-emitting devices are always on and displaying a particular color, such as green, to indicate a normal state. An alert status can be indicated by changing the color, such as to yellow, and causing the light-emitting devices to slowly flash. An alarm status can be indicated by changing the color, such as to red, and causing the light-emitting devices to flash more rapidly.
The present disclosure provides a method of providing a visual alert in response to an environmental condition or change in condition. In exemplary embodiments the method may comprise providing an apparatus according to the present disclosure, positioning at least one sensor in an environmental location to be monitored, such as a room, hall, ventilation hood area, or the like, instructing a controller to determine the initial sensor condition and to receive periodic sensor data. The method further comprises comparing the periodic sensor data with prior sensor data to determine whether the difference in measurements is greater than a predetermined amount. If the predetermined amount is exceeded the controller actuates the LEDs to light in a preset or predetermined pattern, color, or other state so as to provide a visual alert of the change in condition greater than the predetermined amount. The method may also include resetting the controller using the display device interface, for example, once the condition has been changed and the sensor data returns to be less than the amount which caused the alert to be triggered. In exemplary embodiments, the apparatus may be in electrical communication with one or more environmental control apparatus, such as, but not limited to, a thermostat, heat or air conditioning unit, humidifier, or the like. The controller can be instructed by a user or automatically by the controller programming to send a signal to actuate, de-actuate or adjust the environmental control apparatus so as to change the environmental condition. In addition to environmental condition detection sensors, the apparatus may be in electrical communication with other sensors, such as heart monitors, hospital bedside patient monitors, and the like.
In exemplary embodiments, the sensors may communicate with the controller by a wired electrical connection, or may be in wireless communication.
Although only a number of exemplary embodiments have been described in detail above, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments, without materially departing from the novel teachings and advantages. Accordingly, all such modifications are intended to be included within the scope of this disclosure as defined in the following claims.
While the methods, equipment and systems have been described in connection with specific embodiments, it is not intended that the scope be limited to the particular embodiments set forth, as the embodiments herein are intended in all respects to be illustrative rather than restrictive.
As used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise.
“Optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.
Throughout the description and claims of this specification, the word “comprise” and variations of the word, such as “comprising” and “comprises,” means “including but not limited to,” and is not intended to exclude, for example, other additives, components, integers or steps. “Exemplary” means “an example of” and is not intended to convey an indication of a preferred or ideal embodiment. “Such as” is not used in a restrictive sense, but for explanatory purposes.
Disclosed are components that can be used to perform the disclosed methods, equipment and systems. These and other components are disclosed herein, and it is understood that when combinations, subsets, interactions, groups, etc. of these components are disclosed that while specific reference of each various individual and collective combinations and permutation of these may not be explicitly disclosed, each is specifically contemplated and described herein, for all methods, equipment and systems. This applies to all aspects of this application including, but not limited to, steps in disclosed methods. Thus, if there are a variety of additional steps that can be performed it is understood that each of these additional steps can be performed with any specific embodiment or combination of embodiments of the disclosed methods.
It should further be noted that any patents, applications and publications referred to herein are incorporated by reference in their entirety.
