    摘要: A dual communication frequency RFID circuit includes a logic unit for processing data signals received or transmitted at a first frequency by a first antenna or at a second frequency by a second antenna, and a unit for managing the state of a tamper loop linked to the integrated circuit by two connection terminals. The management unit includes a first low-pass filter linked to a first connection terminal, a second low-pass filter linked to a second connection terminal, a current source for supplying a current through the first low-pass filter, a switch linked at the output of the second low-pass filter, and a first inverter connected between the current source and the first low-pass filter for supplying an output signal for the state of the tamper loop to the logic unit.

    摘要: A system and method provides access to antennas of an electronic article surveillance system via WiFi and the Internet. Each antenna of the EAS system has a WiFi chip associated with its controls and the WiFi chip relays the antennas operating parameters as well as its reading of electromagnetic noise in its environment to the Internet. A remote technician can review the information provided by the antennas of the EAS system and optimize their operation with each other and their environments. In some embodiments, remote software can optimize the operation of the EAS system antennas. In some embodiments, the WiFi chip is an aftermarket addition.

    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.
