Patent EP-0309251-A1 (EP)
Inventor: PARKE IAN
IPC: H04N7/26
Filed: 1988-09-22
Abstract: A motion vector suitable for motion-compensated prediction in an inter-frame differential video coder is derived by comparison of each block of a current frame with the corresponding region of a previous frame and with shifted regions of the previous frame. Rather than dealing with each block in turn, the apparatus carries out all comparisons involving a line n of the video signal before commencing comparisons involving n+p (where p is the number of lines encompassed by a block).

Abstract: The invention relates to a profiled covering panel (1) comprising a matrix based on a hydraulic binder internally reinforced by longitudinal strips (2). It makes it possible to prevent, in the event of the panel breaking due to inadvertent overloading, the broken pieces from falling, whilst preventing the longitudinal cracking problems encountered when the strips are placed in a corrugation trough. For this purpose, each strip (2) is totally disposed in a zone (C) of the corrugation trough (3) between a central part (A) and an intermediate part (B), this zone corresponding to a circular sector delimited by two radii forming angles of at least 10 DEG  and at most 45 DEG with the median axis of the corrugation trough. <IMAGE>

Abstract: Dans les procédés connus de marquage de surfaces de semi-conducteurs par bombardement laser, on appose soit un codage à barres en écriture dite Hardmark soit des caractères en écriture dite Softmark. Le nouveau procédé doit permettre un marquage exempt de défauts de cristaux par un codage à barres (Sk) en écriture dite Softmark qui autorise, grâce à une densité de caractères supérieure, une lecture et un décodage plus fiables. Le codage à barres (Sk) est réalisé au moyen d'éléments de barre (Se) de largeur identique (b) formés chacun, par bombardement laser, d'une suite de points de fusion type Softmark (SSp) se chevauchant. De préférence, les barres étroites (sSt) sont constituées d'un élément de barre (Se) et les barres larges (bSt) sont constituées de deux éléments de barre (Se) apposés avec un faible espacement (a) l'un par rapport à l'autre. Ce nouveau procédé permet le marquage, exempt de défauts de cristaux, de puces semi-conductrices, notamment de tranches au silicium.

Abstract: A method of searching a matrix (41) of binary data is effective to find search regions (42-R to 50-­R) in which straight lines (42-50) may be found, with the straight lines being perpendicular to the original direction of scanning which produced the matrix (41) of binary data. Firstly, the predetermined area (41) is scanned along predetermined search scans in a direction which is parallel to the original direction of scanning to search for the presence of binary one indicia, to generate search results for each of said search scans, with a binary one indicating the presence of data. Then, the search results of preselected said search scans are combined in an AND-­logic manner to generate AND-scans, and preselected AND-scans are combined in an OR-logic manner to generate OR-scans. The resulting OR-scans are used to define the search regions (42-R to 50-R) in which to look for the straight lines (42-50) which are perpendicular to the original direction of scanning.
