An electronic label reading system includes an interrogator including a transmitter and a receiver. The system also has a transmitter antenna connected to the transmitter for generating an interrogation electromagnetic field through which objects possessing code responding labels may pass. The code responding labels include label receiving antennas for receiving from the interrogation field a label interrogation signal, and generate label reply signals, and, from the label reply signals, reply electromagnetic fields. The system also has a receiver antenna connected to the receiver for receiving the reply signals from the label reply fields. The interrogation field and label reply fields provide a communication channel from the labels to the interrogator, and the interrogator signals to the labels condition information indicative of the condition of the communication channel.

Electronic label reading system

A process for continuous manufacture of electronic modules ( ) including the steps of providing a microcircuit and antenna receiving side on a continuous strip ( ) and module surface areas; arranging, e.g., by printing, on the module surface area, a plane spiral antenna ( ) wholly arranged to this area; fixing on said strip ( ) a microcircuit ( ) provided with contact pads ( ) after placing an insulator between the microcircuit the strip ( ); making an electric connection between the antenna ( ) and of the microcircuit.

Single receiving side contactless electronic module continuous manufacturing process

The invention concerns contactless electronic labels ( ) associated with a reading device ( ). The invention lies in the fact that the reading device ( ) also comprises a generator generating sequences of pulses which characteristically modulate ( ) a signal at a carrier frequency (F ), the modulation making it possible to code information to be transmitted to the electronic labels. These sequences of pulses are detected ( ) and interpreted ( ) by the electronic labels ( ) and supply different signals which act on certain circuits in the electronic labels, in particular for inhibiting certain functions.
