Abstract

Mobile telephone handset or headset utilizes a sensor for determining whether a power-saving mode should be entered. The headset or handset includes at least one display screen for displaying communication information relative to the device, a sensor for providing a command signal, and control means for controlling operation of the display screen responsive to the command signal. The device has a first mode in which the display screen displays at least some information and a second mode in which the display screen utilizes less power than the first mode. The command signal causes a change between the first mode and the second mode. This Abstract is provided to comply with rules requiring an Abstract that allows a searcher or other reader to quickly ascertain subject matter of the technical disclosure. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

Claims

1. A communication device comprising:

at least one of a display screen for displaying information and a backlight for lighting a portion of the device;

a sensor for providing a command signal;

control means for controlling the operation of the device in response to the command signal;

wherein the device has a first mode in which the device utilizes power and a second mode in which the device utilizes less power than the first mode; and

wherein the command signal causes a change between the first mode and the second mode.

2. The communication device of claim 1, wherein the device is portable.

3. The communication device of claim 2, wherein the device comprises a mobile telephone.

4. The communication device of claim 2, wherein the device comprises a mobile telephone headset.

5. The communication device of claim 1, wherein the sensor is adapted for detecting a head of a user adjacent the display screen for reduced power consumption.

6. The communication device of claim 1, wherein the sensor comprises a proximity sensor for sensing an object within a predetermined proximity zone.

7. The communication device of claim 1, wherein the sensor comprises a pressure sensor for sensing when a pressure has passed a predetermined threshold.

8. The communication device of claim 1, wherein the sensor comprises a temperature sensor for sensing when a temperature has passed a predetermined threshold.

9. The communication device of claim 1, wherein the sensor comprises a light sensor for sensing when an amount of light has passed a predetermined threshold.

10. The communication device of claim 1, wherein the sensor comprises two sensors working in conjunction with each other to determine whether a change between the first mode and the second mode should be made.

11. The communication device of claim 1, wherein the sensor works in conjunction with a timer to determine whether a change between the first mode and the second mode should be made.

12. The communication device of claim 1, wherein the sensor works in conjunction with an application to determine whether a change between the first mode and the second mode should be made.

13. A method of controlling the operation of a communication device, the method comprising the steps of:

providing at least one sensor within the communication device;

transmitting a command signal for controlling operation of the device; and

controlling an amount of power provided to a portion of the device in response to the command signal.

14. The method of claim 13, wherein the controlling step is responsive to receipt of the command step.

15. The method of claim 14, further comprising terminating the controlling step responsive to non-receipt of the command signal.

16. The method of claim 13, wherein the step of providing a command signal is repeated at predetermined intervals.

17. The method of claim 13, wherein the sensor is a proximity sensor for sensing an object within a predetermined proximity zone.

18. The method of claim 13, wherein the sensor is a pressure sensor for sensing when a pressure has passed a predetermined threshold.

19. The method of claim 13, wherein the sensor is a temperature sensor for sensing when a temperature has passed a predetermined threshold.

20. The method of claim 13, wherein the sensor is a light sensor for sensing when an amount of light has passed a predetermined threshold.

21. The method of claim 13, wherein the at least one sensor comprises two sensors working in conjunction with each other to determine whether a change between the first mode and the second mode should be made.

22. The method of claim 13, comprising providing a timer, working in conjunction with the sensor, to determine whether a change between the first mode and the second mode should be made.

23. The method of claim 13, comprising providing an application, working in conjunction with the sensor, to determine whether a change between the first mode and the second mode should be made.
