    摘要: A damping control system disposed at a location of an antenna resonant circuit detects an exciter signal produced by a remotely located EAS transmitter. The damping control system generates a switch control signal in response to the detection of an EAS exciter signal burst. The switch control signal is used to reduce a Q factor of the antenna resonant circuit by selectively controlling at least one switching element connected to the antenna resonant circuit. The damping control system controls a timing of the switch control signal so as to reduce the Q factor at a predetermined time selected to reduce ringing at a trailing edge of each periodic burst.

    摘要: An Electronic Article Surveillance ("EAS") system is provided wherein the system is configured to detect passive radio frequency identification ("RFID") tags. The system can be configured to read the passive RFID tags and produce a corresponding emulated EAS signal to initiate an alarm on a detected tag. The system can transmit the emulated EAS signal to a legacy EAS system thereby utilizing an existing EAS infrastructure. In some embodiments, a composite EAS system is configured to detect RFID tags and other EAS tags, wherein the composite EAS system comprises a legacy EAS system and an RFID-based EAS system configured to produce an emulated EAS signal.

    摘要: Anti-theft asset protection system and method based on electromagnetic confinement techniques that comprise at least one wireless radiant element that generates an electromagnetic confinement space that is adapted to the particular geometry of each one of the possible scenarios without having to incorporate physical barriers or walkthroughs. If the wireless protection device attached to the asset to be protected gets out from the confinement space, it will not receive the surveillance code emitted by the radiant elements, and as a result, it will trigger a local sound alarm and a digital alarm managed, through a communication unit, by an external security platform.

    摘要: Method for reducing undesired alarms in an electronic article surveillance (EAS) system involves measuring a tag response at a first and second pedestal to obtain contemporaneous first and second tag responses. The tag responses are compared to evaluate relative signal strength and thereby discern a lesser signal strength tag response. A reduced level exciter drive signal is applied to a selected one of the first and second pedestals associated with the lesser signal strength tag response. A. detection zone is then monitored to determine the occurrence of a third tag response resulting from the reduced level exciter signal. The approximate location of the tag in relation to the first and second pedestals is determined based on the first, second, and third tag responses.

    摘要: Systems (100) and methods (600) for detecting a location of an EAS security tag (112). The methods involve: determining a first amplitude of a response signal generated by the EAS security tag and received at a first pedestal (102a), and a second amplitude of the response signal received at a second pedestal (102b); processing the first and second amplitudes to determine whether the EAS security tag resides within a specified distance range of the first or second pedestal, a detection zone of an EAS detection system, or a backfield of the EAS detection system; issuing an alarm when the EAS security tag is determined to reside within the specified distance range of the first/second pedestal or the detection zone of the EAS detection system; and preventing issuance of the alarm when the EAS security tag is determined to reside in the backfield of the EAS detection system.
