Abstract:
An apparatus of dynamic feedback control charge pump is provided. The apparatus of dynamic feedback control charge pump receives an input voltage through a voltage regulator. The voltage regulator regulates the input voltage to a base voltage according to a control signal. The charge pump receives the base voltage and provides multiple of the base voltage to an output voltage. A feedback unit provides the control signal to the voltage regulator according to the output voltage. Therefore, the apparatus of dynamic feedback control charge pump can reduce the output voltage ripple and improve the output efficiency of the charge pump.

Abstract:
Multi-layer coatings are disclosed that include (1) a first layer comprising an inorganic oxide network, and (2) a second layer applied over at least a portion of the first layer, wherein the second layer is deposited from at least one liquid composition that is hydrophilic and includes an essentially completely hydrolyzed organosilicate. Also disclosed are substrates coated with such multi-layer coatings, methods of applying such multi-layer coatings to a substrate and methods for improving the anti-fouling, self-cleaning, easy-to-clean, and/or anti-fogging properties of an article.
Abstract:
In a mobile communication system, a relay station (RS) is used for signal exchange with a base station (BS), and includes a first antenna set including at least one antenna, used for signal exchange with the BS, and a second antenna set including at least one antenna, used for signal exchange with a mobile station (MS). The RS selects at least one antenna from the second antenna set for each of the at least one MS, and exchanges a signal with the MS using the selected at least one antenna.

Abstract:
A shock mount is configured sized to receive a disc drive storage system therein and is configured to surround the disc drive storage system. The shock mount has a plurality of sides and is shaped to fit in a housing. A plurality of shock absorbing protrusions extend from the shock mount. The protrusions are of a shock absorbing material and are configured to hold the data storage device at a spaced apart position from the housing and provide shock absorption therebetween.
Abstract:
An apparatus (2) for automatically laying out punching tools on a turret is used in a computer-aided manufacturing system for sheet-metal punching. The system includes a server (1), a database (3), and a number of client computers (7). The apparatus resides in the server, and is used for receiving drawings from the client computers to obtain information on workpieces, selecting punching tools in accordance with sizes and shape of each type of drawing entity of the workpieces and in accordance with materials of the workpieces and machining allowances set by users, selecting a corresponding tool station on the turret for each of the selected punching tools in accordance with a type of the turret and specifications of the selected punching tool, mounting each punching tool on the corresponding tool station, selecting an optimum manufacturing path for each punching tool, and recording punching tool layout information. A related method is also disclosed.
Abstract:
A pre-impact mode of a bumper system is provided by extending a bumper member outwardly and extending a stiffener member downwardly. Both the bumper member and the stiffener member are separately adapted to engage an object. The bumper system includes a bumper member movable between a retracted position and a laterally extended position. A stiffener member is movable between a retracted position and a downwardly extended position. An actuator mechanism is adapted to move the bumper member between the retracted and laterally extended positions and to cause the stiffener member to move between the retracted and downwardly extended positions as a result of moving the bumper member.
