Abstract
Dispositif d'identification du type comprenant un redresseur alimentable inductivement pour alimenter lui-même le dispositif et amener un signal de déclenchement à un générateur d'impulsions à plusieurs sorties. Des réception du signal de déclenchement le générateur d'impulsions produit une séquence prédéterminée d'impulsions sur ses sorties qui sont reliées à un circuit combinatoire à deux sorties, lequel produit, pour chaque combinaison d'impulsions en sortie du générateur, une impulsion sur une de ses deux sorties. Les impulsions apparaissant sur ces deux sorties sont transmises inductivement à un détecteur qui reçoit ainsi un train d'impulsions, en nombre prédéterminé, dont les polarités différentes déterminent un nombre binaire qui constitue le code d'identification. Application comme clé d'identification.
