Abstract: 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.

Abstract translation: 提出了一种高效口袋检测方法。 无线设备通过使用多个低功耗传感器来确定它是否处于过渡状态。 如果设备处于过渡状态，无线设备会启动高耗能传感器，否则如果设备未处于过渡状态，则可以将高功耗传感器关闭。 如果设备处于转换状态，则无线设备使用高功耗传感器来检测设备的当前口袋模式，或者如果设备不处于转换状态则检测到其他方式保持先前的口袋模式。

Abstract: A mobile device includes a motion detector, a processing unit, and a wireless positioning module. The motion detector is configured to detect a motion of the mobile device to obtain a motion signal. The processing unit is configured to do the followings: process the motion signal to obtain a vibration frequency and a vibration regularity of the mobile device; determine a device activity status of the mobile device according to the vibration frequency and the vibration regularity; and generate a control signal when finding that the device activity status switches from a first activity status to a second activity status. The wireless positioning module is configured to identify a first location of the mobile device in response to the control signal.
