Patent GB-2251770-A (GB)
Title: Graphics accelerator system using parallel processed pixel patches
Inventor: NEAVE JOHN WALTER
IPC: G06T17/00
Filed: 1991-01-09
Abstract: A graphics accelerator system which provides improved image rendering speed. One significant bottleneck in such systems is the step of "polygon traversal", where the computer must find out what pixels are covered by a specified polygon. (The polygon is normally defined by a set of linear equations.) The disclosed inventions optimize the memory access, by accessing the patches which are partly inside the polygon. The disclosed system performs polygon traversal with reference to patches of pixels. (The significance of the patches is that all pixels of each patch are processed in parallel.) The polygon is traversed, patch by patch, in a sort of raster-scanning. (That is, all portions of the polygon in one row of patches are mapped out, before the next row of patches is scanned.) Each patch is tested, to detect whether the edge of the polygon (in the current row of patches) has yet been reached: but this test is performed by testing only the pixels on the leading edge of the current patch. After one row of patches is finished, the next row of patches is started at the same root position, but the direction of movement is selected to minimize the chances of stepping through many blank patches before finding the polygon. To rapidly find the interior of the polygon, first-order derivatives (with respect to the direction of pixel movement) of the defining functions are examined. Suppose that the sign of the defining functions is such that any pixel where any defining function is positive is outside the polygon: then the path toward the interior of the polygon can be found by moving in a direction which reduces the value of those functions which are positive. <IMAGE>

Title: Photoconductor film clamping and tensioning system and method of use
Inventor: PRESZLER DUANE ALLEN
IPC: H04N1/08
Filed: 1991-03-26
Abstract: A clamping and tensioning system for securing a sheet of photoconductor film to the surface of a carrier drum includes a clamp rod 98 mounted to the carrier drum by first and second mounting blocks 28, 64 which include elongated slots 42, 76 that allow the clamp rod 98 to rotate about its longitudinal axis and permit linear radial movement of the clamp rod with respect to the carrier drum. The clamp rod 98 includes mounting pins 114 for the edges 116, 118 of the photoconductor film, which edges are releasibly clamped by a clamp bar 126. Leaf spring elements 60, 94 bias the clamp rod 98 radially inward to a first position wherein the film is untensioned. The film is tensioned by rotating the clamp rod 98 about its axis which in turn winds the edges 116, 118 of the photoconductor film about the clamp rod. As the clamp rod 98 is rotated, it moves radially outward with respect to the carrier drum against the bias of the leaf spring elements 60, 94. The clamp rod 98 is held in a second position, wherein the film is tensioned, by a releasible split clamp collar 148. <IMAGE>

Title: Height-control device for vehicles
Inventor: LAICHINGER MARTIN
IPC: B60G21/055
Filed: 1992-05-13
Abstract: A height-control device for a motor vehicle, having two operating cylinders (actuators 11, 12) per vehicle axle and located between a respective wheel suspension and the vehicle body, has proportional pressure-control valves (18, 19) each associated with a respective actuator (11, 12) and having three switching positions for connecting the pressure chambers (15) of the associated actuators (11, 12) to a pressure medium source (25) or to a pressure medium drain (26) or for shutting off the pressure chamber (15). To prevent unstable states of travel in the event of failure of the height-control device, it is ensured by structural measures that the two pressure chambers (15) of the two actuators (11, 12) are interconnected by way of a throttle (38) when the two actuators (11, 12) are in the shutoff phase of the pressure chambers. Greatly differing pressures in the actuators (11, 12) can thereby be equalized at the instant at which the actuators are shut off, so that the unstable behaviour of the vehicle is avoided. Preferably, the restrictor is provided in pressure-tight seat valves (27, 28) which are connected between the proportional pressure-regulating valves (18, 19) and the actuators (11, 12). <IMAGE>
