ELECTRONICALLY DETECTABLE AND DEACTIVABLE LABEL |
摘要 |
<p>The circuit has at least one resonant frequency and is operative in an electronic security system in which the tag circuit is sensed and electronically deactivated to destroy the resonant characteristics of the tag circuit at the detection frequency. The tag circuit is electronically deactivated by a breakdown mechanism operative within the resonant structure of the tag to cause vaporisation of a conductive area or short-circuiting of capacitor plates to destroy the resonant properties of the circuit. A deactivator provides electromagnetic energy at a resonant frequency of the tag circuit of sufficient energy to cause electrical breakdown and deactivation of the tag circuit.</p> |
