Abstract

L'INVENTION CONCERNE UN PROCEDE ET APPAREIL DE CENTRALE D'IDENTIFICATION DE PIECES ET OBJETS SIMILAIRES CONDUCTEURS D'ELECTRICITE. L'EFFET DE CHAQUE PIECE 1 A CONTROLER ET A IDENTIFIER SUR UN CHAMP MAGNETIQUE PRODUIT PAR UNE BOBINE EMETTRICE 101 EST MESURE ET COMPARE (BOBINE RECEPTRICE 201) AVEC UNE VALEUR DE REFERENCE PRODUITE PAR UNE PIECE SEMBLABLE 2 PLACEE EN PERMANENCE DANS UN CHAMP MAGNETIQUE, CRU PAR LA BOBINE EMETTRICE 102, DE MEME INTENSITE. LA PIECE EST ACCEPTEE SI LA VALEUR MESUREE EST SUFFISAMMENT PROCHE DE LA VALEUR DE REFERENCE. L'INVENTION S'APPLIQUE A DES APPAREILS COMMANDES PAR DES PIECES ET DES JETONS
