Abstract: An IP cellular phone with a remote function for controlling a briefing system in a personal computer includes a CPU disposed therein. The CPU is electrically connected to a dial module, a voice control module, a remote control module, a trackball module, a laser project module and a wireless transmitter/receiver that are disposed in the IP cellular phone. The wireless transmitter/receiver is provided for reciprocally and wirelessly transmitting the signals between the CPU and the personal computer. As a result, an IP cellular phone is advantageously altered to have the functions of a presenter.

Abstract: A foolproof mechanism for a server is disclosed for use in a blade server and/or in a similar electronic apparatus having a chassis to which with an insertion portion of a blade board is inserted and coupled horizontally and is constrained vertically. The foolproof mechanism includes a blade housing mounted on an outer side of the insertion portion, a depression structure formed on the blade housing, and an anti-moving button installed loosely in the depression structure. By gravity, the anti-moving button is automatically sunk in the depression structure while the insertion portion is inserted in a correct orientation, thereby smoothly inserting the insertion portion into the chassis; on the contrary, the anti-moving button is automatically projected out of the depression structure while the insertion portion is inserted incorrectly, thereby blocking the insertion portion from inserting into the chassis, thus preventing the insertion portion and the chassis from being damaged.

Abstract: A laser locus ball apparatus for a wireless keyboard includes a base, a laser source generator, a locus ball, a light sensing element and a key cover. The base provides a lateral plate with a locating hole to locate the laser source generator and has another two opposite lateral plates with an engaging wedge at the bottom edge thereof to engage with the key cover. The top plate of the base has a supporting bore to receive the locus ball. A containing space is formed in the base to accommodate the optical sensing element. The laser source generator emits laser to the lower surface of the locus ball. The locus ball is movably received in and supported with the supporting bore such that the lower surface thereof extending downward from the supporting bore to reflect interference stripe figure during the lower surface of the locus ball receiving the laser. The light sensing element senses the laser interference stripe figure within every preset unit time.

Abstract: A fixing mechanism for fixing a disc drive and a locking device thereof solves the inconvenience involved in fixing and disassembling the disc drive. The disc drive has at least one a pair of protrusions located at side walls of the disc drive. The fixing mechanism includes a fixing frame and a locking device. The fixing frame has a pair of assembling walls and at least one receiving space is used for receiving the disc drive. One of the assembling walls has a pair of assembling boards protruding outward and an open sliding slot. The protrusions are slidably installed in the sliding slot. The locking device includes a base part and a locking arm. Two sides of the base part are assembled to the assembling boards. A locking hole formed at the free end of the locking arm correspondingly locks one of the protrusions of the disc drive.

Abstract: A blade server system is described. The blade server system includes a main chassis, a rear module chassis and a mid-plane. The main chassis is formed with slots into which a plurality of sever blades are slidablely inserted from the front end of the main chassis. The rear module chassis is removablely mounted to the rear end of the main chassis, and divided into plural partitions for housing different component modules. The mid-plane is mounted to an end of the rear module chassis, and includes a first face and an opposite second face. The first face has plural connectors electrically connected to the server blades and the second face has plural connectors electrically connected to the component modules. Therefore, when maintenance is needed for the mid-plane, the service engineer only needs to withdraw the entire rear module chassis as a whole, without the need to remove the individual component modules.

Abstract: A PCI card-securing mechanism includes an external housing and a securing component. The external housing has a frame and a receiving plate extending upwardly from the frame. The frame forms with a plurality of slit ports for exposing the PCI card. The receiving plate has a pair of guiding grooves parallel to the slit ports and a pair of assembling slots formed on a top edge thereof. The securing component has a main portion forming a pair of setting bridges, a pair of pulling parts extending outwardly from a top edge of the main portion and a pressing plate bent from a bottom edge of the main portion. The pair of setting bridges are slidably assembled in the pair of guiding grooves, respectively. The pulling parts are disposed in the assembling slots, respectively. The pressing plate presses an edge of the frame to fix the PCI card.

Abstract: A blade server system includes a middle plane board and a server blade. The middle plane board includes a first connector having a number of slots and a positioning hole. The server blade includes a second connector, and by plugging the second connector into the first connector the server blade can be electrically connected with the middle plane board. The second connector includes a number of pins and a positioning stick. The pins are for correspondingly inserting into the slot, and the positioning stick is for inserting into the positioning hole. When the second connector is plugged into the first connector, the positioning stick is inserted into the positioning hole first and then the pins can be aligned with and inserted into the slots.
