Abstract
a. Détecteur de proximité. b. Il comprend deux antennes disposées au bord antérieur d'une porte avec un certain intervalle, des convertisseurs pour convertir les capacités électrostatiques à la terre des antennes en tensions électriques correspondantes, un premier circuit de détection pour détecter un signal différentiel aux sorties des convertisseurs de tension, et un second circuit de détection pour détecter un signal d'addition des signaux de sortie des convertisseurs de tension, de manière que le mouvement de la porte soit commandé par le signal de sortie du premier circuit de détection et par celui du second circuit de détection. c. Concerne la sécurité des portes automatiques, et notamment, des portes d'ascenseurs.
