摘要： An EAS activation/deactivation antenna in accordance with the invention comprises a core; a coil arrangement having at least two coils spirally wrapped about the core, the first coil having a first rotational direction and the second coil having a rotational direction counter to the first rotational direction; and, a current source operatively connected to the coil arrangement. In consequence of the inventive arrangement, a decaying or steady state, alternating or direct current supplied by a current source can excite the coil arrangement to produce a significant near magnetic field and a reduced far magnetic field, for activation or deactivation of EAS markers.

摘要： An adaptive security device includes a tag module and a processor module. The processor module contains a tag disable electronic circuit and a controller. The controller provides tag control commands to the tag disable electronic circuit. The tag disable electronic circuit selectively enables or disables the tag module based on the tag control command. In one embodiment, the tag module is an electronic article surveillance ('EAS') tag module.
