20130033792 | PROTECTION CIRCUIT FOR DIGITAL INTEGRATED CHIP - A protection circuit includes first and second electronic switches. When a CPU socket does not contain a CPU, a signal pin of the CPU socket outputs a high level signal. The first and second electronic switches are turned on. A data transmitting line of a SMBus is connected to a digital integrated chip. The parameters of the digital integrated chip can thus be regulated. When the CPU socket contains the CPU, the signal pin of the CPU socket outputs a low level signal. The first and second electronic switches are turned off. The data transmitting line of the SMBus is disconnected from the digital integrated chip, to prevent damage to the digital integrated chip. | 02-07-2013 |
20110141687 | AIRFLOW SHIELDING DEVICE AND COMPUTER SYSTEM EMPLOYING THE AIRFLOW SHIELDING DEVICE - An airflow shielding device is configured for being secured to fan and includes a first member, a second member, and a plurality of shielding pieces. The first member defines a first through opening. The second member defines a second through opening corresponding to the first through opening. The shielding pieces are rotatably secured between the first member and the second member and rotate between a closed position, where the shielding pieces cover the first through opening, and an open position, where the shielding pieces are located so that air can flow through the first and second through openings. | 06-16-2011 |
20110134603 | COMPUTER SYSTEM WITH DUCT - A computer system includes a chassis, a motherboard, a heat sink, a duct and a fan. The chassis includes a chassis bottom wall. The motherboard with a chip is secured to the chassis bottom wall. The heat sink is secured to the motherboard for cooling the chip. The duct includes a guiding portion and a latch portion located on the guiding portion. The latch portion is secured to the chassis bottom wall. The guiding portion is adjacent to the heat sink to direct airflow to the heat sink. The fan is secured on the latch portion of the duct. The guiding portion of the duct is positioned between the heat sink and the fan. | 06-09-2011 |
20110128687 | COMPUTER SYSTEM - A computer system includes an enclosure defining a window, a cover pivotably attached to the enclosure, a bracket fixed to a bottom of the cover, a pair of rails fixed to a bottom of the bracket and a hard disk slidably retained between the two rails. The cover can be pivoted to an opened position to bring the hard disk to a place out of the enclosure where the hard disk is accessible. The cover can be further pivoted to a closed position to cover the window to thereby receive the hard disk within the enclosure. | 06-02-2011 |
20110121882 | CIRCUIT FOR DETECTING MANAGEMENT ENGINE STATE - A circuit for detecting management engine (ME) state of a computer includes first and second electrical switches, and an indicating circuit. The first and second electrical switches are connected to a south bridge of the computer and respectively receive an ME state signal and a startup signal from the south bridge. The ME state signal and startup signal are operable to turn on or turn off the first and second electrical switches to control the indicating circuit to indicate ME state of the computer. | 05-26-2011 |
20090267563 | ELECTRONIC DEVICE - An electronic device includes a remote control and a main body. The remote control has two contacting portions. The main body is capable of being controlled by the remote control. The main body has two conductive portions and two power supply terminals for supplying the electrical power to the two conductive portions. The contacting portions of the remote control detachably electrically connect with the conductive portions for charging the remote control. | 10-29-2009 |
