摘要： Systems (100) and methods (1400) for verifying a detachment of a security tag (108) from an article. The methods comprise: producing by a detaching unit (106) a first signal at a first frequency and a second signal at a second frequency when the security tag is in proximity thereto; generating, by a non-linear electrical circuit (504) of the security tag, a third signal from the first and second signals applied thereto; ceasing generation of the third signal by the non-linear electrical circuit when at least a first portion (306) of the security tag is moved a certain distance from the detaching unit; and determining by the detaching unit that the first portion of the security tag has been decoupled from a second portion (318) of the security tag when the third signal is no longer being generated by the non-linear electrical circuit.

摘要： An electronic article surveillance antenna system with wide interrogation zones has a number of core transceiver antennas with each connectable to a transmitter. The core transceiver antennas are adapted to be installed adjacent a ceiling of the wide interrogation zone and generate an interrogation signal into the wide interrogation zone. The core transceiver antennas each are connectable to a receiver to receive and detect a response signal from an electronic surveillance marker disposed in the wide interrogation zone. The system also has transceiver antenna coils with each connectable to the transmitter and adapted to be installed adjacent a floor of the wide interrogation zone. The transceiver antenna coils generate the interrogation signal into the wide interrogation zone and each is also connectable to the receiver to receive and detect the response signal from the electronic surveillance marker disposed in the wide interrogation zone.

摘要： A core antenna system for use in electronic article surveillance (EAS) and radio frequency identification (RFID) systems. The core antenna system may include a core antenna. The core antenna may include a core, a first resonant winding disposed around at least a portion of the core, the first resonant winding having a first number of winding turns N1, and a second non-resonant winding disposed around at least a portion of the core, the second non-resonant winding having a second number of winding turns N2, the second number of turns greater than or equal to the first number of turns. The core antenna may be mounted on a shield plate and tuned to an operating frequency on the shield plate such that when the shielded core antenna is further mounted on a mounting surface, e.g., of a checkstand, no significant de-tuning of the antenna takes place.
