Abstract: An adapter card for managing connections between clients and a network server off-loads the connection management burden from the server. The adapter card includes a memory with an embedded proxy application and a communication protocol stack, a processing unit for executing the application code, a network controller for interfacing with an internetwork, and a bus protocol bridge for interfacing with the internal bus of the network server. The proxy application receives client requests on behalf of the server over relatively slow and unreliable network connections, and submits the requests to the server over fast, reliable bus connections.

Abstract: A system and method for reducing the intensity output response time of a liquid crystal display is disclosed. A display driver circuit selectively substitutes compensation data words for data words in a data stream, in order to reduce the intensity output rise time of a liquid crystal display. In one embodiment, the display driver circuit includes a buffer and a rise time compensator. The buffer receives and stores a first data word intended to be written to a particular pixel. The rise time compensator, upon receipt of a second data word intended for the same pixel, retrieves the first data word from the buffer, compares the value of the second data word to the value of the first data word, and selectively outputs either the second data word or a compensation data word, depending on the relative values of the first and second data words.

The guide has a set of alignment marks and a plurality of measurement scales associated with the alignment marks. Each measurement scale corresponds to at least one of the fiducial lines, such that when one of the alignment marks is aligned with a particular fiducial line, the measurement scale corresponding to the particular fiducial line indicates the distance of the blade of the cutting tool from an edge of the sheet material. Particular embodiments of the guide include a flat portion attached to the front of the cutting tool, or alternately, a laser guide rotatably fixed to the front of the cutting tool. Novel methods for cutting a predetermined distance from an edge of a piece of sheet material using the guides of the present invention is also disclosed.

Abstract: A method for creating dummy fill metal patterns (10) in a reflective LCOS array (11) in order to minimize distortion in images reflected from mirrors (14) thereof. A metal fill pattern (50) is selected from an area near a functional circuitry (32) pattern.

Metal sliver(s) (66) or other such artifacts are removed to conform to design specifications, thereby creating a second trimmed metal traces (74) pattern. The second fill metal traces (74) are combined with the functional circuitry (32) traces to form a completed metal trace pattern (76) in an overlay functional and dummy patterns operation (78).
