  • Magnetic core transceiver for electronic article surveillance marker detection
    Patent number: 7978078
    Abstract: A magnetic core transceiver antenna for EAS marker detection is provided. The core includes a stack of amorphous alloy ribbons insulated from each other and laminated together. A coil winding of wire, also insulted from the ribbons, and connected to an electronic controller provides the transmitter and receiver modes. The transceiver antenna is optimized for the dual mode operation, and is smaller and uses less power than conventional air-core EAS antennas with equivalent performance. Complex core geometries, such as a sandwiched stack of different sized ribbons, can be implemented to vary the effective permeability of the core to customize antenna performance. Multiple transceiver antennas can be combined to increase the size of the generated EAS interrogation zone.

  • Apparatus for deactivation of electronic article surveillance tags
    Patent number: 5781111
    Abstract: In accordance with the present invention there is provided an apparatus for deactivating electronic article surveillance tags comprising a deactivation coil, a capacitor, charging means for charging the capacitor to a predetermined level, and an electronic switch connected to the capacitor and the deactivation coil so that when the switch is open the capacitor can be charged by the charging means and when the switch is closed the capacitor can discharge through the deactivation coil.
