Abstract: A support device including a keyboard platform and a bracket for mounting the keyboard platform a work surface to elevate the keyboard platform above the work surface. The keyboard platform is mounted on the bracket for sliding movement relative to an edge of the work surface along a horizontal fore-aft axis. The keyboard platform is mounted on the bracket for tilting movement about a tilting axis perpendicular to the fore-aft axis. The support device includes a lock movable between a locked position wherein sliding/tilting movement of the keyboard platform is prevented and an unlocked position wherein sliding/tilting movement of the keyboard platform is permitted. One aspect includes a clamp provided on the bracket and engageable with the work surface to elevate the keyboard platform above the work surface. One aspect provides a mouse platform pivotally attached to the keyboard platform and configured to support the mouse at a tilted position.

Abstract: The invention is the novel use of Quantum Dots (QDs) for radiation dosimetry and includes novel dosimetry devices, systems and methods. The devices, systems and methods have use in a variety of dosimetry applications such as personal, environmental and research. The system for detecting doses of ionizing radiation comprises; a matrix comprising a photoluminescent semiconductor nanocrystals; an illumination interface for exposing the matrix to non-ionizing radiation; a response characterization interface for measuring photoluminescence, scatter or the optical density of the matrix and identifying differences in the photoluminescence, scatter or optical density caused by exposure to ionizing radiation; and a readout interface to quantify the photoluminescence or optical density differences as doses of radiation.

Abstract: The invention discloses an ultrasonic fat reduction and body shaping machine that includes a treatment head, a wave source carrying apparatus, a mechanical arm, a treatment bed, a lift cylinder body, a touch screen and control circuits. A menu for user selection operation is provided on the touch screen. The treatment head is clamped in the wave source carrying apparatus so as to be fixedly connected to the mechanical arm as a whole. The mechanical arm is fixedly connected to the lift cylinder body that is fastened on the treatment bed-base. The invention is to provide an ultrasonic fat reduction and body shaping machine that facilitates assembling and disassembling of a treatment head, elevates and descends a mechanical arm freely. The ultrasonic fat reduction and body shaping machine has an ultrasonic frequency of 1 MHz to 3 MHz using an ultrasonic emission mode with high intensity, narrow pulse width and low duty cycle.

Abstract: A sulfur-containing palladium-carbon catalyst prepared by loading palladium on an active carbon, mixing the palladium-carbon catalyst with a solvent to form a slurry, adding a sulfide to the slurry to treat the loaded palladium under a predetermined temperature, and removing liquid and drying to obtain the catalyst. The sulfur-containing palladium-carbon catalyst is suitable for making phenylene diamine rubber antioxidant with improved productivity and selectivity.

Abstract: Disclosed is driving circuit for AC contactor for driving a AC contactor, including a first switch connected in series with a winding of the AC contactor, a first diode reversely connected in parallel with the winding of the AC contactor for providing a discharging path for the winding, a DC startup holding unit having an output terminal connected in series with the first switch and a detection terminal connected to a first contact switch of the AC contactor. The DC startup holding unit is configured to selectively convert a DC driving voltage into a first DC voltage or a second DC voltage. When the AC contactor is not magnetized, the DC startup holding unit outputs the first DC voltage. When the AC contactor is magnetized, the DC startup holding unit outputs the second DC voltage.

Abstract: A board-mounted electrical connector (1) includes an insulative housing (10), a number of first terminals (22) and a number of second terminals (26) received in the housing, and a spacer (30) assembled on the housing. The insulative housing includes a base portion (12) defining a number of recesses (124) thereon. Each first terminal includes a contacting portion (222) and a soldering portion (225) extending perpendicularly to a printed circuit board (50). Each second terminal includes a contacting portion (262), a soldering portion (265) extending parallel to the PCB and a connecting portion (264) connecting the contacting portion and the soldering portion. The spacer defines a number of holes (33) for receiving and organizing the soldering portions of the first terminals and forms a number of protrusions (34) cooperating with the recesses of the base portion for organizing corresponding connecting portions of the second terminals to thereby precisely position the soldering portions of the second terminals.
