SYSTEM AND METHOD FOR DETECTING A FALLING STATE OF AN ELECTRONIC DEVICE
First Claim
1. A method for detecting a falling state of an electronic device, the electronic device comprising a global position system (GPS), the method comprising:
- setting a time interval to collect position information of the electronic device;
setting one or more alarm means to alarm when the electronic device is in a falling state;
activating the GPS to locate a position of the electronic device;
acquiring position information of the electronic device from the GPS at each time interval, the position information comprising an altitude value of the electronic device;
acquiring a current altitude value of the electronic device;
calculating an altitude difference between the current altitude value and a previous altitude value acquired in a previous time interval, and calculating an acceleration of the electronic device according to the altitude difference and the time interval;
determining if the calculated acceleration is larger or equal to the acceleration of gravity;
detecting that the electronic device is in a falling state if the calculated acceleration is larger or equal to the acceleration of gravity; and
activating one or more of the alarm means when the electronic device is in a falling state.
