Patent number: 9679469Abstract: A remote control circuit includes a rectifying filter circuit coupled to an alternating current (AC) power source, a power supply module connected to the rectifying filter circuit; a leakage energy collecting circuit connected to the rectifying filter circuit; a remote control signal receiving circuit connected to the leakage energy collecting circuit; and a switch circuit connected to the remote control signal receiving circuit and the power supply module. When the remote control signal receiving circuit receives a remote power on signal, the remote control signal receiving circuit outputs a first signal to the switch circuit, and the switch circuit switches on the power supply module. When the remote control signal receiving circuit receives a remote power off signal, the remote control signal receiving circuit outputs a second signal to the switch circuit, the switch circuit switches off the power supply module.Type: GrantFiled: August 6, 2014Date of Patent: June 13, 2017Assignees: HONG FU JIN PRECISION INDUSTRY (ShenZhen) CO., LTD., HON HAI PRECISION INDUSTRY CO., LTD.Inventors: Ching-Chung Lin, Fu-Shan Cui

Patent number: 9478190Abstract: A video card includes a graphics processing unit, a video interface, and a power interface. The graphics processing unit processes video signals that are not supported by a display device and generates display signals that are supported by the display device. The video interface transmits the display signals to the display. The power interface supplies a first voltage to the display device via the video interface, so as to power on the display device to display the display signals.Type: GrantFiled: October 31, 2013Date of Patent: October 25, 2016Assignee: ShenZhen Goldsun Network Intelligence Technology Co., Ltd.Inventors: Ching-Chung Lin, Fu-Shan Cui

Patent number: 9461455Abstract: A protecting circuit connected between a power supply and a load includes an interface unit, a switching unit, a protection module, a locking unit, and a trigger unit. The interface unit is used for connecting to the load. The switching unit turns on to establish a connection between the power supply and the load when the interface connects to the load and turns off to cut off the connection. The protection module generates a protecting signal when the output of the power supply is in an abnormal state, and the locking unit controls the trigger unit to generate a control signal. The switching unit cuts off the connection in response to the control signal. When the output of the power supply resumes to a normal state, the switching unit automatically resumes the connection by reconnecting the interface with the load.Type: GrantFiled: September 5, 2013Date of Patent: October 4, 2016Assignee: ShenZhen Treasure Technology Co., LTD.Inventors: Ching-Chung Lin, Fu-Shan Cui

Publication number: 20140085756Abstract: A protection circuit connected between a power supply and a load comprises an interface unit, a control unit, and a first switching unit. The interface unit is capable of connecting to the load. The control unit generates a variable duty cycle of a pulse width modulation (PWM) signal when the interface unit is connected with the load. The first switching unit is connected between the control unit and the interface unit. The first switching unit switches between a turned-on state and a turned-off state based on the PWM signal.Type: ApplicationFiled: August 22, 2013Publication date: March 27, 2014Applicants: HON HAI PRECISION INDUSTRY CO., LTD., HONG FU JIN PRECISION INDUSTRY (ShenZhen) CO., LTDInventors: CHING-CHUNG LIN, FU-SHAN CUI
