Patent ID: 8212422

Claim:
A hand-held electronic device capable of protecting data stored therein while falling, comprising: a state-detecting unit for detecting a motion state of the hand-held electronic device and generating state information according to the detecting result of the motion state; a state-determining unit electrically connected to the state-detecting unit and configured to receive the state information and selectively output a fall instruction according to a preset safe movement state parameter; a central processing unit electrically connected to the state-determining unit and configured to receive the fall instruction, trigger storage of operation data during operation of the hand-held electronic device according to the fall instruction, and cause the hand-held electronic device to enter a low current mode upon completion of the operation data storage; a memory unit electrically connected to the central processing unit and configured to store the safe movement state parameter and the operation data; a main power supply unit connected to the hand-held electronic device for supplying power during an operation mode; a standby power supply unit for supplying power required for the low current mode, wherein the capacitance of the standby power supply unit is less than that of the main power supply unit; and a power supply switching unit connected to the main power supply unit, the standby power supply unit, and the central processing unit and configured to switch between the main power supply unit and the standby power supply unit, wherein the central processing unit causes the power supply switching unit to switch to the standby power supply unit upon disconnection of the main power supply unit.
