Abstract

Chacun des systèmes à synchroniser comprend un émetteur et un récepteur de signaux électromagnétiques, un marqueur étant fixé à chaque article pour recevoir ces signaux et émettre d'autres signaux lors du passage par une région prédéterminée. Les systèmes n'ont pas à etre connectés entre eux parce qu'on utilise le réseau de distribution existant.
