Title: Three-dimensional vision system for a robot
IPC: G01S17/89
Filed: 1985-05-15
Abstract: The invention relates to a device making it possible to measure, with respect to an origin point O%, with the aid of a laser 1, 2, the angular coordinates r and c of a laser beam 8 scanning a volume of space C with the aid of the scanning device 2, the reflection of the light 9 from which, onto the objects 3, forms an image on the camera 4. This image is compared with the same image which the extension of the laser beam would form to the rear of the point O% on an identical plane to that where the camera image is formed, this shift _D_ being inversely proportional to the object distance represented by the vector R. These coordinates R, r, c are stored in a memory 7 constructed so that the angular coordinates r and c are the addresses of this (16-bit) memory whereas the vector R is arrayed (stored) in the (8-bit) data.

Patent FR-2600450-A1 (FR)
Inventor: VANVOREN CLAUDE
IPC: G09F3/00
Filed: 1986-06-19
Abstract: The invention relates to a method for the individual marking of precooked anodes used in the production of aluminum by electrolysis in the Hall-Heroult process, and to the anodes produced thereby. These anodes are produced by hot compaction of a carbonaceous paste, and according to the invention, during or immediately after such compaction, a plurality of impressions is formed in the upper part of each anode. The impressions are depressions and/or relief portions, constitute a digital coding for the identification number of each anode, and remain legible until withdrawal of the components of the butt of the worn anode from the electrolysis tank. The marking can be carried out using a binary or ternary code, where the reference plane of the zone of the anode which carries the marking corresponds to a first digit, with other digits corresponding to depressions of a particular depth, depressions of a greater depth, or relief portions.

Patent WO-8802963-A1 (WO)
Inventor: FOUCHE YVON
IPC: H04N7/24
Filed: 1987-10-06
Abstract: L'invention consiste principalement à effectuer la synchronisation de l'horloge d'un émetteur avec un récepteur en utilisant la corrélation totale et/ou la corrélation locale du signal reçu par un code d'émission. La synchronisation permet notamment de fournir une référence de phase nécessaire aux transmissions en modulation de phase. Pour le récepteur de type radio ou télévision l'utilisation d'un filtre adapté étroit (140) permet, au prix d'une diminution du rapport signal/bruit de réduire l'autodistorsion du signal. L'analyse fine du signal permet une synchronisation d'une très grande précision tandis que la pré-synchronisation utilisant des convolueurs à dispositif à transfert de charges (130) permet de limiter le nombre de calculs nécessaires. L'invention s'applique principalement à la réalisation de récepteurs de radio, de télévision ou de récepteurs radar.

Abstract: The invention relates to a method for forming a trihedron from a plane element, and to the plane element itself. This plane element is characterised in that it comprises, in a first lateral strip 4, by appropriate U-shaped cutouts, a flap 18 which can be folded down by pivoting along a hinge 20 defined by a folding line; and, in a corner leaf 14 by a cutout, an opening 22 arranged substantially opposite the hinge 20 essentially parallel to the hinge in the folded-down position against the first lateral strip which is itself folded down so that, by penetration of the folded-down flap 18 in the opening 22 and folding of the flap 18 in the direction of this initial position, a trihedron is thus formed. Perfectly secure locking of this trihedron is thus obtained in a very simple manner.
