Title: Motion analysis of moving images
Inventor: WALTERS CARL WILLIAM
IPC: H04N7/00
Filed: 1992-03-24
Abstract: A composite correlation surface having a high resolution first correlation surface and a lower resolution second correlation surface is calculated. The composite correlation surface thus calculated is then searched for correlation maximum M1, M2. The correlation maximum M1 from within a group of equally valid correlation maxima within the composite correlation surface that has the lowest magnitude displacement vector V1 is used to determine the motion vector for that correlation surface. Once motion vectors have been identified for all of the blocks making up the image, a small group of motion vectors is picked for each block in a vector reduction step prior to further processing. The search for motion vectors for inclusion in this group uses a predetermined selection test and takes place in a primary set of blocks abutting the target block in question and then in a secondary set of blocks surrounding the target block but spaced from the primary set blocks, <IMAGE>

Title: Conductivity modulated semiconductor device
Inventor: HUANG QIN
IPC: H01L29/745
Filed: 1994-02-11
Abstract: To shorten the turn-off time in a bipolar semiconductor device such as an IGBT or thyristor with reduced on-voltage, conductivity modulation is used to reduce switching loss. A minority carrier, which has a conductivity modulation effect, can be supplied from a separately disposed minority carrier injection region (9), and the region (9) can either be connected to or separated from a drain region (8). When a voltage above threshold is applied to a first gate electrode 51 an inversion layer forms below in a base region 3 and electrons are injected from a source 4 into an n-layer 2 and these reach the drain 8. If the voltage on a second gate electrode 53 is high enough, an inversion layer forms below in the minority carrier region 9 thus connecting a source 11 to the drain 8. A short circuit electrode 63 supplies electrons to the source 11 and holes to the region 9, so acting as a converter with holes being injected into the layer 2 from region 9. If the voltage on the second gate 53 is below threshold, the injection stops and minority carriers in the layer 2 are swept to the base 3 and recombine. This allows rapid turn-off from the first gate electrode 51. <IMAGE>
