Filed:

Nov 14, 2000

Appl. No.:

09/712492

Inventors:

Reuel Andrew Ely - Plantation FL
Ronald B. Easter - Parkland FL

Assignee:

Sensormatic Electronics Corporation - Boca Raton FL

International Classification:

H01Q 708

US Classification:

343788

Abstract:

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.

International Classification:

G08B013/14

US Classification:

340/572300, 340/572600

Abstract:

Magnetic security tags/labels require to be activated/deactivated by magnetic/demagnetization and to enable this to be effected in bulk, with tagged products packed in a crate or stacked on a pallet, the invention proposes the provision of bulk magnetization/demagnetization coils generating a powerful magnetic field which is applied to the crate or pallet with a particular orientation which ensures that regularly shaped (e.g. rectangular) packages packed/stacked together and each carrying a security tag/label will each be subjected to a magnetic field component directed appropriately for magnetization/demagnetization of the respective tag/label irrespective of the particular orientation of the tag/label on the particular package. One embodiment uses spaced-apart coils (--) with an enclosure () therebetween into which a rectangular crate/pallet can be placed, the enclosure () constraining the crate/pallet to a particular orientation within the enclosure, and the coils (--) having a particular orientation with the enclosure.

Appl. No.:

9/133529

Inventors:

Ronald B. Easter - Parkland FL

Assignee:

Sensormatic Electronics Corporation - Boca Raton FL

International Classification:

G08B 1314

US Classification:

361149

Abstract:

A device for deactivating magnetomechanical EAS markers includes a storage capacitor and a coil for generating a deactivation field. A bridge arrangement of four switches interconnects the coil with the storage capacitor and with circuit ground. The switches are controlled to apply a train of DC pulses to the coil such that the pulses have alternating polarities and decreasing amplitudes.

International Classification:

G06K 19/07
H04B 5/02

Abstract:

Systems and methods for operating a security tag. The methods comprise: receiving a first wireless signal using a receive circuit of the security tag; inducing a voltage in the receive circuit of the security tag while the first wireless signal is being received; performing operations by a controller to selectively close a switch while the voltage is being induced in the circuit; causing a release of a mechanical component of the security tag by allowing energy to flow from the receive circuit to the mechanical component when the switch is closed; and performing operations by the controller to prevent damage to the mechanical component as a result of the security tag being a certain distance from an external device.
