Patent CA-2096431-A1 (CA)
IPC: H04N7/50
Filed: 1991-12-03
Abstract: Multi-mode predictive interpolative systems and methods for interlaced video sequences use past even fields as well as cur-rent and past odd fields to code current even fields. Block matching units (40, 42, 44) find for each block of pixels of a current even field to be coded, the corresponding block which matches it most closely in the current odd field, the past odd field and a past even field and calculate appropriate motion vectors corresponding to the best matched blocks. Based on the best matched blocks, and averages thereof, the best mode generator (60) selects a best mode block which most closely matches the block to be coded and derives an error block representing the pixel by pixel differences between the block to be coded and the best mode block. Signals representing the error block, the mode chosen, and the motion vectors corresponding thereto are then sent for transmission for use by a decoder.

Inventor: BROWN GORDON C
IPC: B21D1/06
Filed: 1993-10-26
Abstract: The invention concerns a method of locating and repairing dents in motor vehicle panels. The initial step in the method is to locate the dent in the panel. This is done by positioning a magnet and a metal ball on or adjacent to opposite surfaces of the panel so that the magnet and ball attract one another through the panel. The relevant one of the magnet or ball is to the location of the dent on one side of the panel with the result that the other of the magnet or ball moves to the dent on the other side of the panel. The magnet is typically carried by a mechanical pressing tool which can then be used to lever out the dent by working the metal around the dent.
