    摘要： Systems and methods for operating a security tag of an Electronic Article Surveillance (“EAS”) system. The methods involve providing a unique identifier from the security tag to an application installed on a mobile communication device via a first short-range communication when the security tag is attached to an article for sale. A second short-range communication is received by the security tag from the mobile communication device that comprises a detachment command. The detachment command is received by the security tag exclusively after the article has been successfully purchased. Thereafter, the security tag verifies that the second short-range communication is intended to be processed thereby. Next, the security tag performs operations to actuate a detachment mechanism in response to the detachment command so that the security tag can be detached from the article for sale.

    摘要： Systems (100) and methods (500, 600) for adaptively managing power for an Energy Harvesting System (“EHS”). The methods involve: measuring a light intensity level available in a surrounding environment; wirelessly communicating a first wireless signal from the EHS (100) to a remote device (700) for causing the light intensity level to be increased by remotely turning on a light source (106, 108) or opening a cover preventing light emitted from the light source from reaching the EHC, when the light intensity level is below a pre-specified level; using an Energy Harvesting Circuit (“EHC”) to recharge a rechargeable battery (310) when the light intensity level rises above the pre-specified level; and wirelessly communicating a second wireless signal from the EHS to the remote device for causing the light source be turned off or the cover to be closed, when the capacity or state-of-charge of the rechargeable battery reaches a pre-specified value.

    摘要： 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.
