Abstract

A monitor display unit mounted on a surface and in electronic communication with a system or device to be monitored, comprising a face plate, a back plate having at least a portion of a side edge being translucent or transparent, a logic controller, and at least one light-emitting device in electronic communication with the controller. Actuation of the light-emitting device causes light to pass through the side edge of the back plate, thereby being visible to a viewer at an angle that can be generally parallel to the surface on which the display unit is mounted.

Claims

1. An apparatus for providing side-viewable illumination of a wall-mounted plate to allow a wider off-axis viewing angle for alerts to changes in a condition being monitored by a sensor, the apparatus comprising:

a) a face plate having a face, sides and an opening;

b) a back plate having a front face, rear face and sides, the sides having at least a portion thereof being transparent or translucent;

c) a controller;

d) at least one light-emitting device associated with the back plate rear face and positioned such that light emitted by the light-emitting device at least partially passes through the back plate sides;

e) at least one sensor in communication with the controller such that the controller can actuate or change a condition of at least one light-emitting device in response to the sensor information received by the controller; and

wherein the sides allow a wider off-axis viewing angle to see a change in the at least one light-emitting device in response to the sensor information.

2. The apparatus of claim 1, further comprising an electrical screen in electrical communication with the controller and adapted to at least be partially received within the face plate opening.

3. The apparatus of claim 2, further comprising means associated with the controller for providing wireless communication.

4. The apparatus of claim 1, wherein the back plate rear face has a reflective material associated therewith.

5. The apparatus of claim 1, further comprising a plurality of fasteners, each fastener adapted to join the face plate to the back plate.

6. The apparatus of claim 1, further comprising a user interface associated with the controller.

7. The apparatus of claim 1, wherein the controller is adapted to actuate the at least one light-emitting device.

8. The apparatus of claim 1, wherein the controller is adapted to control at least one of the actuation, brightness, color, sequence or pattern of light emitted from each light-emitting device.

9. The apparatus of claim 1, wherein the controller further includes timer circuitry so as to dim, brighten or turn on or off the at least one light-emitting device according to at least one preset time interval.

10. The apparatus of claim 1, further comprising means associated with the controller for providing wireless communication.

11. The apparatus of claim 10, further comprising a visual signal projection device that is adapted to be in wireless electronic communication with the controller.

20. A method of visual alert in response to an environmental condition or change in condition to allow a wider off-axis viewing angle to changes in a condition being monitored, the method comprising:

a) providing an apparatus according to claim 1;

b) positioning at least one sensor in an environmental location to be monitored;

c) instructing a controller to determine the initial condition of the sensor and to receive periodic sensor data;

d) comparing the periodic sensor data with prior sensor data to determine whether the difference in measurements is greater than a predetermined amount;

e) when the predetermined amount is exceeded, actuating a light emitting device to light in either a predetermined pattern, color, or other state so as to provide a visual alert; and

wherein the apparatus allows a wider off-axis viewing angle to see a change in the at least one light-emitting device in response to the predetermined amount being exceeded.

21. The method of claim 20, further comprising resetting the controller using the display device interface, once at least one subsequent measurement after step e) is less than the predetermined amount.

22. The apparatus of claim 20, further comprising a visual signal projection device that is adapted to be in wireless electronic communication with the controller.

12. An apparatus for providing side-viewable illumination of a wall-mounted plate to allow a wider off-axis viewing angle for alerts to changes in a condition being monitored by a sensor, the apparatus comprising:

a) a face plate having a front face, a rear face, sides, and a display opening;

b) a rear plate adapted to mount either to or within a wall or other structure;

c) a bezel having

i) a front surface,

ii) a rear surface,

iii) exterior side edges,

iv) interior side edges,

v) a rim extending at least partially around the bezel exterior side edges and defining a recessed area, and

vi) at least one opening extending at least partially through the bezel;

d) at least one light-emitting device adapted to be received within the bezel opening whereby light emanating from the at least one light-emitting device is at least partially directed toward the bezel side edge such that the light is visible when viewed at an angle generally parallel to or at an acute angle with respect to the plane of front surface of the faceplate;

e) a controller in electrical communication with the at least one light-emitting device for controlling the at least one light-emitting device;

f) at least one sensor in communication with the controller such that the controller can actuate or change a condition of at least one light-emitting device in response to the sensor information received by the controller; and

wherein the bezel allows a wider off-axis viewing angle to see a change in the at least one light-emitting device in response to the sensor information.

13. The apparatus of claim 12, wherein the face plate further comprises an electrical screen in electrical communication with the controller.

14. The apparatus of claim 12, wherein the bezel edge has a surface that can transmit light in a diffused manner.

15. The apparatus of claim 12, wherein the bezel edge has a surface that is frosted.

16. The apparatus of claim 12, wherein the bezel is generally rectangular or square and has four corners, wherein a light-emitting device is disposed proximate to each corner.

17. The apparatus of claim 12, wherein the at least one light-emitting device is at least one light-emitting diode (“

LED”

).

18. The apparatus of claim 17, wherein the LED is an RGB LED.

19. The apparatus of claim 12, wherein the bezel further includes a display device and a display device opening adapted to receive a portion of the display device, the display device opening having an edge that is at least partially coated with a reflective coating such that at least a portion of light from the at least one light-emitting device directed toward the display device opening edge is reflected away from the display device opening edge and back toward the bezel edge.
