Abstract: A mounting apparatus for mounting a power supply having a first connector on a front side, includes an enclosure, a bracket, and a board. The enclosure includes a rear wall defining an opening for the power supply passing therethrough. The bracket is mounted to the enclosure below the opening, capable of supporting the power supply. A second connector protrudes up from a front end of the bracket, configured for engaging with the first connector of the power supply. The board is attached to a rear side of the power supply, to cover the opening of the rear wall. A plurality of latching slots is defined in the enclosure or the bracket. A plurality of hooks is formed on the board, to engage in the plurality of latching slots.

Abstract: A heat dissipation system for an electronic device comprises a base, a fan, a pulse width modulation speed control circuit controlling the speed of the fan, a converter outputting a voltage signal, a selection switch connected to the motor, and a control element provided on the base, connected to the switch and to the converter. When the control element is operated, the switch selectively enables the motor be connected to the output of the pulse width modulation speed control circuit or to the output of the converter, and when the motor is electrically connected to the converter, the control element can modify the output voltage of the converter.

Abstract: A connector includes a base defining a plurality of holes, and a plurality of pins inserted into the corresponding holes. The pins include a ground pin, a voltage signal pin, and a power-on signal pin. Wherein the length of the ground pin extending into a corresponding hole is longer than that of the voltage signal pin, while the length of the voltage signal pin is longer than that of the power-on signal pin.

Abstract: An exemplary computer system includes a host computer and a mouse. The host computer comprises vertical and horizontal scrolling drivers. The mouse includes a scroll wheel, a sensor and a switch connected in series. The scroll wheel generates signals corresponding to navigation commands. The sensor senses the signals, and converts the signals to a format suitable for the vertical and horizontal scrolling drivers. The switch is connected to the vertical and horizontal scrolling drivers selectively. The vertical or horizontal scrolling drivers which is connected to the switch enables navigating in vertical or horizontal directions according to the generated signals respectively.
