System and procedure for producing particular functions in electronic labels that may have data transmitted to them to inhibit or enable certain functions

摘要

Invention concerns electronic labels (10) associated with a reading device (40). The reading device comprises a pulse generator, which generates a sequence of pulses which then characteristically modulate (50) a carrier frequency signal (FO), used to send encoded data to the electronic labels. The pulse sequences are detected (22) and interpreted (26) by the electronic labels.- DETAILED DESCRIPTION - According to the received signals the electronic labels (10) enable or inhibit certain functions. An INDEPENDENT CLAIM is made for a procedure for encoding electronic labels and for reading them
