Abstract: An elevation adjustable display module mounting arrangement for notebook computer is constructed to include a front mainframe shell, a rear mainframe shell pivoted to the rear side of the front mainframe shell, a display module, and a coupling board coupled between the display module and the rear mainframe shell for enabling the display module to be turned relative to the rear mainframe shell and/or turned with the rear mainframe shell relative to the front mainframe shell.

Abstract: A notebook computer comprises a housing including an internal control unit, a recess on a top surface, and wireless receiving means electrically coupled to the control unit; and detachable input means received in the recess and including wireless transmission means which is enabled as the input means is detached from the housing for activating a radio frequency (RF) transmission from the wireless transmission means to the wireless receiving means while entering inputs through the input means.

Abstract: A notebook computer with exchangeable LCD (liquid crystal display) unit is provided. The notebook computer makes use of a connector secured to the bottom of the LCD unit by fixing to a printed circuit board which is electrically coupled to the LCD unit and an LCD energy converter, engagement members secured to hinges of LCD unit for coupling the LCD unit and the body together, a bracket extended from one end of one engagement member for securing to the printed circuit board, and a receptacle on the body engaged with the connector. This eliminates the wiring process of prior art, resulting in a reduction of assembly time. Also, this makes a replacement of different size LCD unit possible.

Abstract: This invention purposes a reduced-width low-error multiplier that can be used in the DSP (Digital Signal Processing) approach of digital communication system. We derive a binary compensation vector to compensate the error caused by the reduction of area without any hardware overhead. We also implement the compensation structure in Array and Booth multiplier to reduce hardware complexity.

Abstract: A liquid crystal display and a rotating device thereof are proposed. A liquid crystal screen of the liquid crystal display is supported by a stand and can be rotated clockwise and counterclockwise with the use of the rotating device being connected to a back side of the screen. In application of a positioning portion of the rotating device in cooperation with positioning holes formed at the back side of the screen, the screen can be maintained in position by the engagement between the positioning portion and the positioning holes, or can be rotated by separating the positioning portion from the positioning holes, in a manner that the screen is prevented from colliding a base of the stand.

Abstract: A composite actuating device is provided for use on an electronic device, such as an electronic notepad or an electronic dictionary machine. The composite actuating device of the invention includes a casing, a cover adapted to be reclosably hinged to the casing and having a locking structure provided in one end thereof, and a power switch mounted in the casing, a button which can trigger the power switch when operated; and a latching device which is capable of locking the cover in closed position on the casing when engaged with the locking structure on the cover, the latching device being linked to the button such that the latching device is disengaged from the locking structure on the cover when the button is operated to trigger the power switch. This allows the actions of unlocking the cover and switching on the power of the electronic device to be simultaneously achieved simply by operating one button by the user.

Abstract: A power-on protective structure for expansion cards installed in a portable computer or the like is provided. The power-on protective structure allows the replacement of the expansion card currently installed in the portable computer to be carried out only when the power supply to the expansion card is disconnected so that the data stored in the expansion card will not be damaged or lost due to inadvertent detachment of the expansion card from the portable computer while the power is still on. The power-on protective structure includes a casing; a battery compartment formed in the casing for accommodating at least one battery therein; a receptacle formed in the casing for accommodating an expansion card therein; a first cover for covering the battery compartment; and a second cover for covering the receptacle.
