Abstract

A thermostat for a building includes a halo light emitting diode (LED) system including one or more LEDs configured to emit light and a halo diffuser structured around at least a portion of an outer edge of the thermostat. The halo diffuser is configured to diffuse the emitted light of the one or more LEDs around at least the portion of the outer edge of the thermostat. The thermostat includes a processing circuit configured to receive one or more data streams, determine whether the one or more data streams indicate a building emergency condition, and operate the one or more LEDs of the halo LED system to indicate the building emergency condition to a user.

First claim

What is claimed is:

1 . A wall mounted display and sensor unit for a building, the wall mounted sensor comprising:
a sensor configured to sense an environmental condition; a display; a halo light emitting diode (LED) system comprising one or more LEDs configured to emit light around at least a portion of an outer edge of the wall mounted display and sensor unit; and a processing circuit configured to receive one or more data streams, determine whether the one or more data streams indicate a building emergency condition, and operate the one or more LEDs of the halo LED system to indicate the building emergency condition to a user and configured to provide an indication of the environment condition on the display.

2 . The wall mounted display and sensor unit of claim 1 , wherein the processing circuit is configured to provide instructions related to the building emergency condition on the display.

3 . The wall mounted display and sensor unit of claim 1 , wherein the halo LED system further comprises one or more waveguides, wherein each of the one or more waveguides is associated with one of the one or more LEDs of the halo LED system, wherein each of the one or more waveguides is configured to transmit the light emitted from one of the one or more LEDs to a halo diffuser, wherein each of the one or more waveguides is coupled to the halo diffuser at a first end of the one or more waveguides and is proximate one of the one or more LEDs at a second end of the one or more waveguides.

4 . The wall mounted display and sensor unit of claim 1 , further comprising:
an enclosure comprising a front portion and a back portion, wherein a halo diffuser is coupled to the front portion and the back portion and is located between the front portion and the back portion.

5 . The wall mounted display and sensor unit of claim 1 , wherein the processing circuit is configured to operate the one or more LEDs of the halo LED system to indicate the building emergency condition to the user by operating the one or more LEDs in a pattern to indicate one or more emergency response directions to the user prompting the user to perform a user response to the building emergency condition.

6 . The wall mounted display and sensor unit of claim 5 , wherein operating the one or more LEDs in the pattern to indicate the one or more emergency response directions comprises activating the one or more LEDs sequentially to indicate an emergency navigation direction.

7 . The wall mounted display and sensor unit of claim 1 , wherein the processing circuit is configured to operate the display to display one or more emergency response directions in response to a determination that the one or more data streams indicate the building emergency condition.

8 . The wall mounted display and sensor unit of claim 7 , wherein the processing circuit is configured to generate a plurality of navigation directions, each navigation direction associated with a priority level, prioritize the plurality of navigation directions, and cause the display screen to display a highest priority level navigation direction of the plurality of navigation directions.

9 . The wall mounted display and sensor unit of claim 7 , wherein the one or more data streams comprise a building data stream generated by a building management system and a weather data stream generated by a weather server;
wherein the wall mounted display and sensor unit comprises a communication interface configured to receive the building data stream from the building management system via a network and the weather data stream from the weather server via the network; wherein the processing circuit is configured to:
cause the display to display non-emergency information based on the building data stream;
determine whether the weather data stream indicates an emergency weather condition; and
override the display of the non-emergency information by causing the display screen to indicate the one or more emergency response directions in response to a determination that the weather data stream indicates the emergency weather condition.

10 . The wall mounted display and sensor unit of claim 9 , wherein the one or more emergency response directions comprise a building map and one or more evacuation directions, wherein the one or more evacuation directions comprise at least one of one or more directions to a building exit or one or more directions to an emergency shelter in the building;
wherein causing the display to display the one or more emergency response directions comprises causing the display screen to display the building map and the one or more evacuation directions.

11 . The wall mounted display and sensor unit of claim 9 , wherein the one or more emergency response directions comprise an arrow indicating a route through the building for the user to follow, wherein causing the display screen to display the one or more emergency response directions comprises causing the display screen to display the arrow.

12 . The wall mounted display and sensor unit of claim 11 , wherein the arrow comprises a first portion and an arrow border surrounding the first portion, wherein the first portion is a first color and the arrow border is a second color different than the first color.

13 . A display device for a building, the display device comprising:
a wireless interface; a sensor configured to sense an environmental condition; a display; a halo light emitting diode (LED) system comprising:
one or more LEDs configured to emit light;
a halo diffuser structured around at least a portion of an outer edge of the display device, wherein the halo diffuser is configured to diffuse the emitted light of the one or more LEDs around at least the portion of the outer edge of the display device; and
a processing circuit configured to operate the one or more LEDs of the halo LED system to indicate a building emergency condition to a user, wherein the emergency condition is determined using data received via the wireless interface, wherein the processing circuit configured to provide an indication of the environment condition on the display.

14 . The display device of claim 13 , wherein the processing circuit is configured to receive one or more data streams, determine whether the one or more data streams indicate the building emergency condition, and operate the one or more LEDs of the halo LED system to indicate the building emergency condition to the user.

15 . The display device of claim 13 , wherein the processing circuit is configured to determine a display device condition that requires user input and operate the one or more LEDs of the halo LED system to indicate the display device condition to the user.

16 . The display device of claim 13 , wherein one or more waveguides are coupled to the halo diffuser at a first end of the one or more waveguides and is proximate to one of the one or more LEDs at a second end of the one or more waveguides.

17 . The display device of claim 13 , wherein the display device comprises an enclosure comprising a front portion and a back portion, wherein the halo diffuser is coupled to the front portion and the back portion and is located between the front portion and the back portion.

18 . The display device of claim 13 , wherein the processing circuit is configured to operate the one or more LEDs of the halo LED system to indicate the building emergency condition to the user by operating the one or more LEDs in a pattern to indicate one or more emergency response directions to the user prompting the user to pe
