Filed:

Dec 8, 1997

Appl. No.:

8/986597

Inventors:

Steve R. Maitin - Lake Worth FL
Ron Easter - Parkland FL

Assignee:

Sensormatic Electronics Corporation - Boca Raton FL

International Classification:

G08B 2100

US Classification:

340676

Abstract:

A system and method for setting the activation state of electronic article surveillance markers, tags, and labels being transported on a conveyor system is provided. The system includes a pair of electromagnetic transmitting coils mountable on opposite sides of a conventional conveyor section, an electronic controller, and can include a remote external controller for manual operation. The electromagnetic transmitting coils are mounted within sensor housings that include one or more sensors to automatically sense an article traveling on the conveyor system and trigger the transmission of preselected activation or deactivation electromagnetic pulses when the article is in the proper location. The system can include an inhibiting sensor input to prevent the automatic transmission of an activation/deactivation pulse for specific preselected articles. The system includes a logic scheme to preselect and shape the activation or deactivation electromagnetic pulse.

Abstract:

Systems () and methods () for verifying a detachment of a security tag () from an article. The methods comprise: producing by a detaching unit () 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 () 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 () 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 () of the security tag when the third signal is no longer being generated by the non-linear electrical circuit.
