1. Technical Field
The present disclosure relates to suspending apparatuses, and particularly, to an automatic suspending apparatus for a computer.
2. Description of Related Art
Cost-effective computer systems using suspending circuits to save electrical energy are developed to replace ordinary computer systems. However, the computer systems using suspending circuits need to switch operation manually, the users usually forget to do it, resulting in wasting the electrical energy.

The voltage regulating circuit 10 is to be connected to an external power source to provide voltages to the image identifying module 20. The voltage regulating circuit 10 can be a known circuit, such as a voltage regulating chip 7805 or 7905. In other embodiments, the voltage regulating circuit 10 can be connected to a power supply of the computer 50 to provide voltages to the image identifying module 20.
The image identifying module 20 includes an image capturing device 21, an amplifying circuit 22, and an image identifying unit 23. The control module 30 includes a timing module 31 and a signal simulation module 32. The voltage regulating circuit 10, the image capturing device 21, the amplifying circuit 22, the image identifying unit 23, the timing module 31, the signal simulation module 32, and the interface 40 are connected in sequence. In one embodiment, the image capturing device 21 may be a camera. The amplifying circuit 22 can be a known circuit, such as, an amplifier. The interface 40 can be a universal serial bus (USB) interface.

The interface 40 of the automatic suspending apparatus is to be connected to a USB interface of the computer 50. The computer 50 provides voltages to the signal simulation module 32 and the timing module 31 via the USB interface of the computer 50 and the interface 40.
In use, the image capturing device 21 gets image information of a user in front of the computer 50 and sends the image information of the user to the amplifying circuit 22. The image information of the user is amplified via the amplifying circuit 22 and sent to the image identifying unit 23. The image identifying unit 23 receives the amplified image information and determines whether body information of the user of the computer 50 exists in the amplified image information according to body character data stored in the image identifying unit 23. When the body information does not exist in the image information, the image identifying unit 23 outputs a working signal to the timing module 31, to control the timing unit 310 to record time. When the recorded time reaches the preset time of the setting unit 312, the sending unit 314 sends an enable signal to the signal simulation module 32. The signal simulation module 32 outputs a sleep signal to the computer 50 via the interface 40 according to the enable signal, to control the computer 50 to enter into the sleep state. In one embodiment, the image identifying unit 23 may use existing face detecting technology to determine whether body information exists in the image information.
When the body information exists in the image information, the image identifying unit 23 outputs an interrupt signal to the timing module 31. The reset unit 316 of the timing module 31 receives the interrupt signal from the image identifying unit 23, and clears the timing unit 310 according to the interrupt signal.
The automatic suspending apparatus determines whether body information of the user of the computer 50 exists, via the image identifying module 20. Once the body information of the user does not exist in the image information, the control module 30 will control the computer 50 to enter into the sleep state. Therefore, the automatic suspending apparatus is power-saving.
