    摘要: The invention concerns contactless electronic labels (10) associated with a reading device (40). The invention lies in the fact that the reading device (40) also comprises a generator generating sequences of pulses which characteristically modulate (50) a signal at a carrier frequency (F0), the modulation making it possible to code information to be transmitted to the electronic labels. These sequences of pulses are detected (22) and interpreted (26) by the electronic labels (10) and supply different signals which act on certain circuits in the electronic labels, in particular for inhibiting certain functions.

    摘要: The present invention relates to a method and device for associating auxiliary information with principal information, and to a device for monitoring the reproduction of principal information recorded on a track, whereby the auxiliary information is coded in an auxiliary signal of limited frequency and superposed on the principal signal, to be recorded in said track. The device comprises a detection circuit connected at the output of the reader head to detect an auxiliary signal associated with the principal information and occupying a limited range of frequencies and a recording device for recording the auxiliary information. The invention is more particularly applied to the monitoring of the public reproduction of recordings.

    摘要: 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.
