Abstract

A system for power management and safety protection and a method thereof are presented. The system and method are applicable to a computer device having a sensor. The sensor detects position information of a user relative to the computer device so as to determine whether to enter a sleep mode or a recognition mode. The sensor also detects motion information of a particular motion of the user so as to return to an operating mode.

Claims

1. A method for power management and safety protection, applicable to an electronic device, comprising:

performing an operating mode by the electronic device;

continuously sending a low-frequency signal by a sensor, so as to detect a position of a user;

obtaining departure position information by the sensor, so as to command the electronic device to perform a sleep mode;

obtaining approach position information by the sensor, so as to command the electronic device to perform a recognition mode;

continuously sending a high-frequency signal by the sensor, so as to measure a particular motion of the user;

obtaining a motion message by the sensor;

determining whether the motion message is identical to a preset motion password; and

returning to the operating mode if the motion message is identical to the motion password.

2. The method for power management and safety protection according to claim 1, further comprising:

displaying a comparison error if the motion message is not identical to the motion password, after the step of determining whether the motion message is identical to a preset motion password in the recognition mode.

3. The method for power management and safety protection according to claim 2, further comprising:

setting a limit value for the number of the comparison error, and ending the recognition mode if the number of the comparison error exceeds the limit value.

4. A system for power management and safety protection, applicable to an electronic device, the electronic device being set with at least an operating mode, a sleep mode, and a recognition mode, the system comprising:

a sensor; and

a frequency controller, electrically connected to the sensor, for controlling the sensor to send a low-frequency signal or a high-frequency signal;

wherein when the electronic device is in the operating mode, the frequency controller controls the sensor to send the low-frequency signal, so as to detect departure position information and approach position information of a user relative to the electronic device, thereby commanding the electronic device to enter the sleep mode or the recognition mode; and

when the electronic device is in the recognition mode, the frequency controller controls the sensor to send the high-frequency signal, so as to measure motion information of the user, thereby commanding the electronic device to return to the operating mode from the sleep mode.

5. The system for power management and safety protection according to claim 4, wherein the sensor comprises a transmitter, a receiver, and a signal processor, the signal processor is adapted to command the electronic device to perform the operating mode, the sleep mode, or the recognition mode.
