Abstract: A sense amplifier circuit comprises a first inverter configured to provide a first trigger point during a pre-charge stage of a READ operation of a memory cell and provide a second trigger point either lower or higher than the first trigger point during a sense stage of the READ operation of the memory cell. The sense amplifier circuit further comprises a plurality of inverters coupled between an output of the first inverter and an output of the sense amplifier and a pre-charge device. The sense amplifier circuit having a dynamic trigger point can deliver faster data access time as well as less power consumption.

Abstract: A sense amplifier circuit includes a precharge circuit configured to precharge a bit line coupled to a sensing node in response to a precharge control signal and a sense output circuit. The sense output circuit includes a sense output inverter coupled to the sensing node. The sense output inverter is disabled during bit line precharging and for a period after bit line precharging is complete, and thereafter the sense output inverter is enabled.

Abstract: A stretching assembly for cloth has a heating furnace, a pressing device and a shaping device. The heating furnace has two opposite sidewalls and a channel. The channel is formed through the opposite sidewalls of the heating furnace and has an inlet and an outlet. The pressing assembly is set to face the inlet of the heating furnace and has a first pressing wheel and a second pressing wheel. The first pressing wheel has multiple annular protruding segments formed on an external surface of the first pressing wheel. The second pressing wheel parallel the first pressing wheel to form a curved clearance between the pressing wheels and has multiple annular concave segments formed on an external surface of the second pressing wheel. The shaping device is set to face the outlet of the heating furnace, aligns with the pressing device and has two shaping wheels.

Abstract: A zoom lens including a first lens group and a second lens group arranged in sequence from a magnified side toward a reduced side is provided. The first lens group has a negative refractive power and includes a first lens, a second lens, a third lens, and a fourth lens arranged in sequence from the magnified side toward the reduced side, of which the refractive powers are respectively positive, negative, negative, and positive. The second lens group has a positive refractive power and includes a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens, a tenth lens, and an eleventh lens arranged in sequence from the magnified side toward the reduced side, of which the refractive powers are respectively positive, negative, positive, negative, positive, negative, and positive. The eighth lens, the ninth lens, and the tenth lens together form a triple cemented lens.

Abstract: An LED lamp includes an optical part, a heat dissipation member and an electric part. The optical part includes a hollow light penetrable tube and an LED module received in the tube. The heat dissipation member is received in the tube to mount the LED module thereon. The electric part include a circuit board and a rechargeable battery arranged in the tube, and two end covers arranged at two opposite ends of the tube. The LED module is provided with at least one first LED and at least one second LED. The at least one first LED and the at least one second LED cooperatively function as a main light source to provide normal illumination when an external AC power source is supplied normally. The at least one second LED independently function as an auxiliary light source to provide emergency illumination when the external AC power source is interrupted.

Abstract: A systolic squarer comprises a systolic array classified into five cell modules by pipeline and regulation according to each operational circuit. According to fundamental structures, the five cell modules constitute the systolic squarer. Each of the cell modules is selected from a group consisting of plural full adders, plural half adders and plural AND gates. Thereby, the five cell modules are suitable for applying to process a great number of digital signals of data, speeding up processing time, and reducing hardware cost and power consumption.

Abstract: A cloth hood is made by punching a flexible cloth into a pair of bilaterally symmetrical twin pieces and stitching them together. The cloth hood includes a gap formed at a position corresponding to that of each eye in respective pieces, a jutting portion below each gap, a recess portion defined at somewhere below the jutting portion and along the peripheral stitch line of the cloth hood, an extension end defined below the recess portion, another recess portion arranged at a position almost exactly opposite to the mentioned recess portion and top and bottom ends of the cloth hood shaped in arc style. As the cloth hood can be closely and flexibly attached onto a user's head, it is possible to prevent hair or scalp bits from being dropped to the floor without incurring any discomfort to the user.

Abstract: A nail guiding mechanism of nailing gun composed of a gun body, a nail magazine and the nail guiding mechanism. The nail guiding mechanism includes a bottom board, a middle board and a top board. The bottom board is connected between the gun body and the nail magazine. The middle board is locked on the top face of the bottom board. The middle board is formed with multiple connecting holes for multiple locating members to fit therein. The locating members protrude from the top face of the middle board. The top board is mounted on the top face of the middle board. The top board is formed with multiple locating holes respectively corresponding to the locating members. The locating members are respectively passed through the locating holes to protrude from the top board. A press shank and a latch ring are pivotally disposed on the top board. When pressing down the press shank, the latch ring is tightly latched with the locating members to fixedly connect the top board with the middle board.

Abstract: A virtual computer verification platform is provided with a verifying and debugging environment so as to develop a new microprocessor chip, a new system software, a new firmware and a new peripheral chip. The virtual computer verification platform includes a simulation system and a set of on-line debugging auxiliary tools, wherein the microprocessor chip can be designed in a Behavior model, a RTL model and a Gate model. The message communication for integrating the whole simulation system is implemented through a message passing mechanism supported by UNIX IPC (Inter-Process Communication) and PLI (Programming Language Interface) supported by Verilog.
