Abstract:
A power supply to provide operation power for cooling fans includes a non-stop power system to provide DC power in normal conditions to a remote switch control circuit to set a computer in an ON or OFF condition. The non-stop power system also outputs the DC power to a fan actuation control circuit to drive a rear end cooling fan. The fan actuation control circuit and the remote switch control circuit are bridged by a cooling delay unit. The cooling delay unit receives a computer ON/OFF signal from the remote switch control circuit and outputs another signal to enable the cooling fan to operate for a period of time before stopping.

Abstract:
An input device with a multi-direction type scroll wheel includes a multi-direction command type switch and a scroll wheel for controlling the switch to output a command. The switch includes a base, a controller, and a pair of positioning bodies. An interior of each positioning bodies is provided with a contacting lead set. An interior of the scroll wheel provided with a guiding portion. When the scroll wheel is rotated forward or backward, moved leftward or rightward, or moved upward or downward, the controller is simultaneously moved by the guiding portion in accordance with the motion of the scroll wheel, thereby electrically connecting the contacting lead sets so as to generate various command signals. The prevent invention achieves the object of outputting various command signals by utilizing multi-direction operation of a single scroll wheel and has the advantages of minimization, simple structure and assembly, and easy operation.
Abstract:
The present invention discloses a fastener with lateral fastening mechanism, including an outer case, a slide block, a claw-shaped head, and a flexible member. The outer case is a hollow tubular member. A swing lever is pivotally connected inside the outer case. The slide block can move freely to a first position where the slide block is hidden inside the outer case, and to a second position where the slide block sticks out of the outer case. One end of the slide block is pivotally connected to the claw-shaped head, and the flexible member can constantly provide force for pushing the claw-shaped head and the slide block. A guide area of the slide block can interact with the swing end of the swing lever, and in the state of interaction, the position of the slide block can be decided to be either at the first position or the second position.

A piezoelectric power supply has a piezoelectric transformer circuit configuration which is alterable flexibly according to varying loading power requirements. It includes a control unit (control IC), a power switch (MOSFET) and an inductor to drive a piezoelectric transformer unit to actuate a high voltage and power load such as a cold cathode fluorescent lamp. The piezoelectric transformer unit consists of a plurality of piezoelectric transformers coupled in parallel. The specification of the piezoelectric transformers (single sheet piezoelectric transformers or low level laminated piezoelectric transformers) and parallel coupling number may be altered according to the required power of the load to change the voltage and current output by the piezoelectric transformers.
