Abstract: A computer mouse includes a body, a control module, a power supply, and a lighting module. The control module and the power supply are mounted in the body. The power supply is connected to the control module and the lighting module. The light module includes a first light emitter, a second light emitter, and a lighting control unit. The first light emitter emits warm colored light. The second light emitter emits very bright light. The lighting control unit can be used to selectively turn on the first light emitter or the second light emitter.

Abstract: A current test system for a hard disk drive includes an adapter board, a test device, two cables and two current clamps. The hard disk drive is connected to the test device through the adapter board. The two cables are connected to two power routes of the adapter board, respectively. While the test device tests the hard disk drive through the adapter board, the two current clamps respectively clamp the two cables to determine the current through the two power routes.

Abstract: A mounting apparatus that can be used to selectively mount a first type of data storage device or a second type of data storage device includes a bracket, and a circuit board mounted to the bracket. The bracket includes a rear board defining an opening. The circuit board includes a first side surface, and a second side surface opposite to the first side surface. A port protrudes from the second side surface, to extend through the opening to be exposed out of the bracket. A first connector or a second connector is selectively set on the first side surface of the circuit board, to be electrically connected to the port and the first type of data storage device or the second type of data storage device.

Abstract: A key includes a frame with a top, a fluorescent layer coated on the top, and a symbol protruding up from the fluorescent layer.

Abstract: A BIOS refresh device includes a first socket, a second socket, and a jumper. The first socket includes a first elastic contact, a first voltage contact, and a first ground contact. The second socket includes a second elastic contact, a second voltage contact, and a second ground contact. The jumper includes a first pin, a second pin, a third pin, and a fourth pin. The first pin is electronically connected with the second elastic contact. The second pin is electronically connected with the first voltage contact or the second voltage contact. The third pin is electronically connected with the first elastic contact. The fourth pin is electronically connected with the second ground contact or the second ground contact.

Abstract: An apparatus and method controls a speed of a fan in a computer. The apparatus includes a signal generator, a signal buffer, a signal switch, and an integrated baseboard management controller (IBMC). The IBMC includes a general purpose input output (GIPO) pin and a signal output port. The IBMC determines whether the IBMC operates normally by detecting a voltage status of the GIPO pin. The signal generator generates a first pulse width modulation (PWM) signal according to a system temperature of the computer when the IBMC does not operate normally. The IBMC generates a second PWM signal to according to the system temperature of the computer when the IBMC operates normally. The signal switch controls the speed of the fan according to the first PWM signal or the second PWM signal.

Abstract: A pin test assistant device includes a shaft and a hook. The shaft is made of strong lightweight material that is easily formed into a shaft, and the hook is made of material that resists heat. If a pin on an integrated circuit (IC) chip needs to be tested, the hook is positioned against the underside of the pin, then a heating device is used to heat the pin for softening the pin. After the pin is softened, the hook is used to bend the pin up to for a test of the pin. After the test, the hook is used to press the pin back into an original position.

Abstract: An electronic device with redundant fan control function includes a first fan, a first control module, a first power supply, a first switch unit, a second fan, a second control module, a second power supply, and a second switch unit. When the first power supply stops working, the second power supply powers the first fan and the second fan, and the first power supply sends a control signal to turn on the first switch unit to allow a group of control information output by the second control module to control the first fan. Therefore, the first fan and the second fan can work normally to dissipate heat from the electronic device.
