Portable electrical apparatus and method for detecting state of the same
First Claim
1. A portable electrical apparatus comprising:
- a sensor for sensing a movement of the portable electrical apparatus to generate a sensing signal;
a micro-controller for receiving the sensing signal and comparing a threshold value with a sensing value corresponding to the sensing signal; and
a wireless positioning module coupled to the micro-controller, for performing localization of the portable electrical apparatus to generate a plurality of position data corresponding to a location of the portable electrical apparatus;
wherein when the sensing value is greater than the threshold value, the micro-controller loads the position data generated within a predetermined period starting from right after the sensing value is greater than the threshold value, the micro-controller compares the loaded position data with each other, and an alarm signal is sent out according to a comparison result, wherein when the micro-controller determines that all the loaded position data are the same, the wireless positioning module sends out the alarm signal.

Abstract
A portable electrical apparatus includes a sensor, a micro-controller, and a wireless positioning module. The sensor is configured for sensing a movement of the portable electrical apparatus to generate a sensing signal. The micro-controller is configured for receiving the sensing signal and comparing a threshold value with a sensing value corresponding to the sensing signal. The wireless positioning module is configured for positioning the portable electrical apparatus to generate a plurality of position data corresponding to a location of the portable electrical apparatus. When the sensing value is greater than the threshold value, the micro-controller loads the position data generated within a predetermined period, which is right after the sensing value being greater than the threshold value, compares the loaded position data with each other, and an alarm signal is sent out according to a comparison result.
