Abstract

Cette invention concerne un système d'identification automatique d'objets (212, 214) déposés dans une zone particulière tel qu'un conteneur, un sac, un transporteur, ou un tas. Une étiquette (216, 218), fixée à chaque objet, possède un code individuel d'identification et peut émettre un signal codé à l'aide du code d'identification lorsqu'elle reçoit un signal d'interrogation. Ce système comprend également un conteneur (220) qui comporte une ouverture en entonnoir (224) afin que l'on puisse y déposer des objets. Un ensemble antenne (230), dont la forme correspond à celle de l'ouverture, est monté sur cette dernière. Un lecteur (236) d'étiquettes, placé à l'extérieur du conteneur (220), comprend des circuits électroniques qui génèrent le signal d'interrogation (lequel pourrait alimenter l'étiquette), et reçoivent le signal codé émis par l'étiquette.
