Claim Text:
1. A mobile device, comprising: a motion detector having a power-saving mode and a detection mode, in the detection mode, the motion detector being configured to detect a motion of the mobile device to obtain a motion signal; a processor, configured to: a wireless positioning module configured to identify a first location of the mobile device in response to the control signal and to identify a second location of the mobile device prior to identifying the first location of the mobile device such that the motion detector is triggered to operate in the detection mode to detect the motion of the mobile device in response to the second location residing within a parking area, wherein the processor determines the device activity status of the mobile device according to the vibration frequency and the vibration regularity by: mapping the vibration frequency and the vibration regularity to a point of a 2-dimension (2D) coordinate, wherein one axis of the 2D coordinate corresponds to the vibration frequency and the other axis of the 2D coordinate corresponds to the vibration regularity.
