Abstract: A computer device includes a microprocessor, a voltage converter circuit converting a first voltage of a system power into a second voltage, a control circuit controlling supply of the second voltage and a detection circuit detecting whether power abnormality at the peripheral device has occurred. When confirming that the system power is being supplied normally, the microprocessor generates a first enable signal to enable the voltage converter circuit. When confirming that the voltage converter circuit functions normally, the microprocessor generates a second enable signal to enable the detection circuit. The detection circuit generates a first detection signal according to detection result for the microprocessor to determine whether to supply the second voltage to the peripheral device. When the first detection signal indicates that power abnormality has not occurred, the microprocessor generates a third enable signal to enable the control circuit to supply the second voltage to the peripheral device.

Abstract: A display interface circuit includes a first transistor and a second transistor electrically connecting in series between a first motherboard power and a display power. A first body diode of the first transistor has a current direction opposite a second body diode of the second transistor. When a display device powers up but a motherboard powers downs, a first control circuit turns on the first transistor and a second control circuit turns off the second transistor such that a current does not leak from the display power toward the first motherboard power due to the second body diode. When the display device powers down but the motherboard powers up, the first control circuit turns off the first transistor and the second control circuit turns off the second transistor such that the first motherboard power is not outputted to a video display interface due to the first body diode.

Abstract: A trackball control device for a game console includes a base, a trackball and a face panel. The base includes three bearing rollers thereon. Two of the bearing rollers are perpendicular to one another and respectively provided with a decoder. The other bearing roller not having the decoder is located between the two bearing rollers having the decoder. The base includes pillars at four corners thereof. The trackball is disposed between the three bearing rollers. The face panel is locked to the pillars. A portion of the trackball is exposed out of an opening of the face panel. The three bearing rollers are to receive and position the trackball. The trackball is operated smoothly to lower resistance when the trackball is operated. When the trackball is operated, the two sensors detect the displacement of the X-axis and Y-axis for operation of the screen of the game console.
