Power Saving Mechanism for In-Pocket Detection

摘要

A method of efficient pocket detection is proposed. A wireless device determines whether it is in a transition state by using a plurality of low power-consuming sensors. The wireless device powers on a high power-consuming sensor if the device is in the transition state, or otherwise keeps the high power-consuming sensor off if the device is not in the transition state. The wireless device detects a current pocket mode of the device using the high power-consuming sensor if the device is in the transition state, or otherwise keeps a previous pocket mode if the device is not in the transition state.

1. A method, comprising:
determining whether a wireless device is in a transition state by using a plurality of low-power sensors, wherein the wireless device comprises the plurality of low-power sensors; powering on a high-power sensor if the wireless device is in the transition state, otherwise keeping the high-power sensor off if the wireless device is not in the transition state, wherein the wireless device comprises the high-power sensor; and detecting a current pocket mode of the wireless device using the high-power sensor if the device is in the transition state, otherwise keeping a previous pocket mode if the wireless device is not in the transition state.
