Abstract

A system for increasing component longevity in a display device includes: a display device; a sensor for detecting an audience associated with the display device; and a control subsystem connected to the sensor. The control subsystem is configured to deactivate at least one component of the display device when no audience is detected by the sensor. A method of increasing component longevity includes determining the presence or absence of an audience with respect to a display device; and deactivating at least one component of the display device when the audience associated with the display device is not present.

Claims

1. A system for increasing component longevity, comprising:

a display device;

a sensor for detecting an audience associated with said display device; and

a control subsystem connected to said sensor, wherein said control subsystem is configured to deactivate at least one component of said display device when no audience is detected by said sensor.

2. The system of claim 1, wherein said control system is configured to activate said at least one component when an audience is present.

3. The system of claim 1, wherein said at least one component comprises a light source.

4. The system of claim 3, wherein said light source comprises at least one of a xenon lamp, Light Emitting Diode or laser.

5. The system of claim 1, wherein said at least one component comprises a power subsystem for providing power to said display device.

6. The system of claim 1, wherein said sensor comprises a motion sensor.

7. The system of claim 1, wherein said sensor comprises a camera.

8. The system of claim 1, wherein said sensor comprises a proximity sensor.

9. The system of claim 1, wherein said sensor comprises a heat sensor.

10. The system of claim 1, further comprising a management policy of said control subsystem.

11. The system of claim 10, further comprising a user interface of said control subsystem for adjusting said management policy.

12. The system of claim 1, wherein said sensor is configured to detect an unconscious audience, said control subsystem being configured to deactivate said at least one component of said display device when said unconscious audience is detected.

13. A method of increasing component longevity, comprising:

determining the presence or absence of an audience with respect to a display device; and

deactivating at least one component of said display device when said audience associated with said display device is not present.

14. The method of claim 13, further comprising reactivating said display device component when said audience is present.

15. The method of claim 13, wherein said determining the presence or absence of an audience comprises receiving sensor data and applying a policy for interpreting said sensor data.

16. The method of claim 15, further comprising receiving user input through a user interface of said display device to make changes to said policy.

17. The method of claim 13, wherein said display device component comprises a light source.

18. The method of claim 17, wherein said light source comprises at least one of a xenon lamp, Light Emitting Diode or laser.

19. The method of claim 13, wherein determining the presence or absence of an audience further comprises determining whether said audience is unconscious and deactivating said at least one display device component when said audience is unconscious.

20. A system for increasing component longevity, comprising:

a display device;

means for detecting an audience associated with said display device; and

means for to deactivating at least one component of said display device when no audience is detected by said means for detecting.
