Title: Method of manufacturing integrated circuits with options programmable by mask and circuits obtained by this method
Inventor: GAUDRONNEAU YVES
IPC: H01L21/8246
Filed: 1985-09-13
Abstract: The invention relates to a method of manufacturing integrated circuits for providing several different circuits with sets of very similar masks. The circuits have identical configurations but are differentiated by functional features obtained through the choice of the type of doping (enhanced or depleted) of certain transistors of the circuit. Thus, the choice of channel doping for the transistors T1 and T2 implies a permanent connection or an absence of permanent connection between two circuit nodes.

Title: Method of processing the signal delivered by a radar system for detecting the approach of an individual, and radar device implementing this method
Inventor: QUINET JEAN-BERNARD
IPC: G01S15/52
Filed: 1986-02-18
Abstract: The invention relates to an acoustic radar operating on the "sonar" principle, i.e. measuring the time of return of short periodically emitted pulses. The analysis of these pulses yields an instantaneous image of the scene under surveillance. This instantaneous image is compared 20 with a previously acquired reference image 10 and, in the event of a disagreement between them, the newly-formed echo is studied 30 more thoroughly in such a way as either to trigger an alarm 40 or possibly to update 50, 60 the reference image. The device can be used particularly outside in order to keep watch on the porch of a dwelling, by virtue of the excellent rejection of outside disturbances (air movements, swaying of branches, temperature variations, etc) which reduces the number of false alarms to a minimum.

Filed: 1986-12-16
Abstract: L'invention concerne un appareil transducteur optique comportant une source de rayonnement optique, émettant un rayonnement situé dans une première bande de longueurs d'ondes ainsi qu'un détecteur optique qui reçoit le rayonnement de cette source. Le transducteur optique reçoit via une fibre optique 2, un rayonnement de longueur d'onde située dans une large bande de longueurs d'ondes, émis par une diode photo-émettrice 1 utilisée à puissance réduite. Le transducteur comporte une plaque mobile 21 ayant une moitié transparente neutre, et l'autre moitié revêtue d'un filtre 23 ayant une caractéristique de transmission qui varie rapidement dans la largeur de la bande de la diode 1. Une deuxième fibre optique 5 reçoit le rayonnement qui traverse la plaque 21 et l'envoie à deux détecteurs 7 et 8 respectivement sensibles à deux longueurs d'ondes différentes. Les signaux de sortie respectifs des deux détecteurs varient selon la proportion de rayonnement passant à travers les parties transparente et filtrante de la plaque 21. Un comparateur 9 compare ces signaux de sortie afin d'indiquer la position de la plaque 21. Cet appareil transducteur optique est utilisé plus particulièrement pour la mesure de déplacements.

Title: Integrated memory with data column redundancy
Inventor: DEVIN JEAN
IPC: G11C29/00
Filed: 1987-02-24
Abstract: The invention relates to the redundancy of integrated memories of high capacity (1 megabit for example). The redundancy makes it possible to replace defective elements with redundant elements. The invention more specifically relates to the replacing of defective columns in memories organised as words of k bits and containing y rows and k groups G0 to G5 of p columns. A redundancy circuit architecture is proposed making it possible to avoid replacing k columns simultaneously when a single column turns out to be defective. To do this, the groups of columns are divided up into m sets of r columns (m and r different from 1) and a redundant column CRa, CRb, CRc is assigned to each set; the position of a defective column is located only within a set and all the columns of like position are replaced with redundant columns, even if not all of the former are defective.
