Abstract: A stand for supporting a computer enclosure includes a bracket, a support member, and a securing member. The bracket includes a first fixing portion and a second fixing portion at opposite ends thereof. The first fixing portion includes a first sidewall extending up and located at a side of the bracket. The second fixing portion includes a horizontal supporting plate extending toward the first fixing portion, configured for supporting an end of the computer enclosure thereon. The support member is perpendicularly fixed to an inner surface of the first sidewall of the first fixing portion of the bracket with one end thereof, for supporting an opposite end of the computer enclosure thereon. The securing member is slidably attached to the support member, and together with the first sidewall of the first fixing portion of the bracket sandwiching the computer enclosure.

Abstract: A clip for mounting a heat sink on a circuit board includes a positioning coil for rotatably engaging with the heat sink. Two elongated arms extend from two ends of a line bisecting the positioning coil respectively, and a pair of hooks formed at distal portions of the two arms respectively for engaging with the circuit board.

Abstract: An exemplary state monitoring circuit includes a data transform unit, a counter, and a clock generator. The data transform unit is connected to a system management bus (SMBUS) to obtain serial signals output from the SMBUS, and convert the serial signals to parallel signals. The counter is connected to a south bridge chip of the system and the data transform unit, for counting parallel signals converted by the data transform unit, if the count is finished, the counter sends a reset signal to the south bridge chip. The clock generator is connected to the counter for providing a clock frequency signal to the counter.

Abstract: A heat sink includes a heat-conductive base comprising a top surface; and a plurality of combined fins extending up from the top surface of the heat-conductive base, every two adjacent fins being spaced from each other with a passage formed therebetween, and the passage having an air inlet at one side of the heat sink, and an air outlet at an opposite side of the heat sink, wherein a top surface of each of the fins slopes down from the middle portion to the air inlet in a streamlined fashion, and from the middle portion toward the air outlet there is steeply sloping portion leading to a gently sloping portion terminating at a steeply sloping end surface of each of the fins. Resistance of the airflow is minimized, and speed of the heat dissipation is enhanced. Therefore, this aerodynamic design allows better airflow through the heat sink.

Abstract: A heat sink includes a base, and a plurality of parallel fins extending up from the base. Every two adjacent fins are spaced from each other with a passage formed therebetween. The passage has an air inlet at one side of the heat sink and an air outlet at an opposite side of the heat sink. A height of each fin gradually reduces from a middle portion to opposite sides of the fin near the inlet and outlet of the passage respectively.

Abstract: A video signal circuit of a notebook computer includes a north bridge chipset, a control module, a VGA port, an A/D converter, a selection module, and a control unit. The north bridge chipset is coupled to the control module and the selection module. The VGA port is coupled between the control module and a display device and a processing device. The A/D converter is coupled between the control module and the selection module. The selection module is coupled to an LCD of the notebook computer. The control unit is coupled to the selection module and the control module. The video signal circuit can be controlled to send a first analog and digital video signals generated by the north bridge chipset to the displaying device and the LCD respectively, or receive a second analog video signal from the processing device and display it on the LCD.

Abstract: A server includes a front module (10), a middle module (50), and a back module (30). The front module includes a first chassis (12) able to receive a plurality of data processing components. The back module includes a second chassis (32) able to receive a plurality of auxiliary components to serve the data processing components via the middle module. Two first rails (18) are mounted to opposite sides of the first chassis of the front module respectively, for slidably engaging with a rack. Two second rails (34) are mounted to opposite sides of the second chassis of the back module, for slidably engaging with the rack.

Abstract: An exemplary server includes a rack, a first module, a second module, and a third module. The first module is slidably attached to an end of the rack in a first direction. The second module is slidably attached to another end of the rack in a second direction opposite to the first direction. The third module is slidably attached to the rack in a third direction perpendicular to the first direction. The first module and the second module are electronically connected to the third module.
