A shift register for use with a liquid crystal display device includes a plurality of stages. A stage of the shift register includes a first controller, a second controller and an output buffer. The first controller charges and discharges a first node. The second controller charges and discharges a second node and a third node. The output buffer outputs a first output signal in response to the state of the first node and a second output signal in response to the state of the second and third nod...

A shift register includes a plurality of register stages. Each register stage includes an output circuit, a first switching circuit and a second switching circuit. The output circuit is capable of outputting a first driving signal. The first switching circuit is used to pull down the output circuit into a low voltage level when the output circuit is not outputting the first driving signal. The second switching circuit is capable of receiving an input signal. The first switching circuit holds ele...

A shift register minimizing bias stress applied to transistors is disclosed. A shift register including n stages outputting scan pluses that are sequentially delayed in a forward or reverse direction thereof, where n is positive integer and wherein each stage includes: a scan direction controller that provides a first or second voltage to a scan direction control node according to a first or second enable signal and controlling the forward or reverse direction output; a first node controller tha...

The present invention proposes to use additional support tabs for the stabilization of the PCI-express add-in cards, in particular, PCI-express add-in cards having a connector the size of one, four or eight links.

A card connector (100) comprises an insulated housing (10), a plurality of electrical contacts (20), an L-shaped shield member (30) assembled in the housing and a guide member (40) located in the shield member. The shield member comprises a main portion (31) and a pair of lateral portions (35, 38) each comprising a guide groove (354, 384) and an L-shaped receiving space (39) surrounded by the main portion and the pair of lateral portions. Each lateral portion has a plurality of tabs (36) project...

A connector assembly with foldable card guides that, when folded, completely cover the array of electrical connectors resident on the connector housing. The connector assembly is shown in the context of a testing unit for automated test equipment. The folding feature is helpful when the connector assembly is not being used inasmuch as the card guides provide environmental protection (i.e. prevent the collection of dirt and/or particulate matter) for the electrical contacts resident in the connec...

This invention describes a unique high-speed implementation for overflow detection logic to be used in high performance shifter functions. The overflow logic makes use of parallelism in combining shift value decoding and mask generation logic with the logic necessary to propagate data. Designs for both 16-bit and 32-bit shifters are presented and performance improvement of the new designs over conventional overflow detection circuits is demonstrated.

A method and apparatus for determining a byte select vector for a crossbar shifter include processing that begins by storing data in a first set of byte locations and in a second set of byte locations. Typically, a data operand is written into the first and a shift value is written into the second set of byte locations. The processing continues by obtaining a shift amount value for the data. The processing then continues by determining, for each byte multiplexor of a set of byte multiplexors ass...

An electrical connector (1) for receiving an electrical card (2) therein. The connector includes an insulative housing (11), and a plurality of conductive terminals (18) received in the housing. The housing includes a beam (12), and a pair of parallel guiding arms (13) extending in a same direction from opposite ends of the beam respectively. A reinforcing plate (16) interconnects the guiding arms to prevent the guiding arms from bending inwardly when the connector becomes heated during use. A m...

Disclosed is a method and apparatus for shifting data from registers. Bits from N registers are shifted as input to a first set of M multiplexors. Control signals are sent into each of the first set of M multiplexors to select bits inputted from one of the registers. The selected bits are outputted to each of a second set of M multiplexors. Control signals are then sent into each of the second set of M multiplexors to select bits inputted from each of the first set of multiplexors.
