TECHNIQUES FOR DEACTIVATING ELECTRONIC ARTICLE SURVEILLANCE LABELS USING ENERGY RECOVERY |
摘要 |
<p>A deactivator having a deactivation antenna coil and a capacitor to store energy. The deactivator converts the stored energy to an alternating current over a deactivation period to generate a deactivation magnetic field when driven through the deactivation antenna coil during the deactivation period. The alternating current defines a ring down envelope during the deactivation period. An energy recovery module having an electrical impedance is coupled to the deactivator to recover a portion of the energy converted to the alternating current during a portion of the deactivation period based on the impedance. Other embodiments are described and claimed.</p> |
