Abstract

Methods and apparatuses for power management are disclosed. In one example, proximity of link status of a wireless communication device is used to determine whether a power conservation mode is implemented.

Claims

1. A computing device comprising:

a wireless transceiver configured to receive a wireless signal from a wireless first wireless communication device over a first wireless communications link, wherein the wireless first wireless communication device is operable to form a second wireless communications link with a wireless second wireless communication device;

an input/output interface adapted to interface with a peripheral device;

a processor; and

a memory storing a power management application configured to receive in the wireless signal from the wireless first wireless communication device an indication of a link connection status of the second wireless communications link and responsive to the link connection status of the second wireless communications link operate the computing device in a normal operation mode or a power conservation mode, the link connection status of the second wireless communications link dependent upon movement of the wireless second wireless communication device with respect to a link boundary with the first wireless communication device.

2. The computing device of claim 1, wherein the computing device is operated in the normal operation mode when the link connection status is a linked status and operated in the power conservation mode when the link connection status is a no-link status.

3. The computing device of claim 1, wherein the power conservation mode comprises sending a power conservation signal to the peripheral device.

4. The computing device of claim 3, wherein the peripheral device is a display or printer.

5. The computing device of claim 1, further comprising a powered device component, wherein the power conservation mode comprises operating the powered device component in a low power state.

6. The computing device of claim 1, wherein the power management application is further configured to monitor a link connection status of the first wireless communications link with the first wireless communication device and responsive to the link connection status of the first wireless communications link operate the computing device in the normal operation mode or the power conservation mode.

7. The computing device of claim 1, wherein the first wireless communication device is a headset and the second wireless communication device is a mobile phone.

8. The computing device of claim 1, wherein the link boundary is approximately 12 meters from the first wireless device.

9. The computing device of claim 1, wherein the second wireless communications link comprises a Bluetooth link, Digital Enhanced Cordless Telecommunications link, IEEE 802.11 link, or infrared link.

10. A method for power conservation comprising:

receiving at a computing device a data associated with a link connection status associated with a wireless communications link between a wireless first wireless communication device and a wireless second wireless communication device, the link connection status dependent upon movement of the wireless second wireless communication device with respect to a link boundary with the first wireless communication device;

operating the computing device in a power conservation mode responsive to the data indicating the link connection status is a no-link status; and

operating the computing device in a normal operation mode responsive to the data indicating the link connection status is a linked status.

11. The method of claim 10, wherein operating the computing device in the power conservation mode comprises sending a power conservation signal to a peripheral device coupled to the computing device.

12. The method of claim 10, wherein operating the computing device in the power conservation mode comprises initiating a low power operation mode of a computing device powered component.

13. The method of claim 10, further comprising:

monitoring at the computing device a link connection status between the computing device and the first wireless communication device;

operating the computing device in the power conservation mode responsive to the link connection status between the computing device and the first wireless communication device being a no-link status; and

operating the computing device in the normal operation mode responsive to the link connection status between the computing device and the first wireless communication device being a linked status.

14. The method of claim 10, wherein the first wireless communication device is a headset and the second wireless communication device is a mobile phone.

15. The method of claim 10, wherein the computing device is a desktop computer or a laptop computer.

16. The method of claim 10, further comprising operating the computing device in the power conservation mode or the normal operation mode responsive to a proximity of the first wireless communication device to the computing device.

17. The method of claim 10, wherein the link boundary is approximately 10 meters from the first wireless device.

18. The method of claim 10, wherein the wireless communications link comprises a Bluetooth link, Digital Enhanced Cordless Telecommunications link, IEEE 802.11 link, or infrared link.

19. A non-transitory computer-readable storage media having computer-executable instructions stored thereon which, when executed by a computer, cause the computer to perform operations comprising:

receiving at a computing device a data associated with a link connection status associated with a wireless communications link between a wireless first wireless communication device and a wireless second wireless communication device, the link connection status dependent upon movement of the wireless second wireless communication device with respect to a link boundary with the first wireless communication device;

operating the computing device in a power conservation mode responsive to the data indicating the link connection status is a no-link status; and

operating the computing device in a normal operation mode responsive to the data indicating the link connection status is a linked status.

20. The non-transitory computer-readable storage media of claim 19, wherein operating the computing device in the power conservation mode comprises sending a power conservation signal to a peripheral device coupled to the computing device.

21. The non-transitory computer-readable storage media of claim 19, wherein operating the computing device in the power conservation mode comprises initiating a low power operation mode of a computing device powered component.

22. The non-transitory computer-readable storage media of claim 19, wherein the operations further comprise:

monitoring at the computing device a link connection status between the computing device and the first wireless communication device;

operating the computing device in the power conservation mode responsive to the link connection status between the computing device and the first wireless communication device being a no-link status; and

operating the computing device in the normal operation mode responsive to the link connection status between the computing device and the first wireless communication device being a linked status.

23. The non-transitory computer-readable storage media of claim 19, wherein the first wireless communication device is a headset and the second wireless communication device is a mobile phone.

24. The non-transitory computer-readable storage media of claim 19, wherein the computing device is a desktop computer or a laptop computer.

25. The non-transitory computer-readable storage media of claim 19, wherein the operations further comprise:

operating the computing device in the power conservation mode or the normal operation mode responsive to a proximity of the first wireless communication device to the computing device.
