摘要： A device (10) for deactivating a magnetomechanical EAS marker includes two coils (24, 28, 26, 30) and an energizing circuit (32) for alternately driving the coils. One coil (24, 28) is driven for one cycle of an alternating power signal, and then the other coil (26, 30) is driven for one cycle, and this sequence is repeated. The driving signal (31) is switched from one coil to the other at a point in time which corresponds to a zero crossing of the current level of the driving signal.

摘要： A reusable EAS tag that is detachable from an article by placing the EAS tag in proximity to a detaching device is provided. The tag includes an energy coupler, a micro-actuator, and a clamping mechanism. The detaching device transmits a signal to the EAS tag to signal detachment, which is received by the energy coupler. The energy coupler converts the energy from the transmitted signal to electrical energy and delivers the electrical energy to the actuator. The actuator converts the electrical energy to mechanical energy to actuate the clamping mechanism and release the tag's locking or clamping mechanism for removal of the tag from the article to which it is attached.

摘要： A deactivation apparatus for an electronic article surveillance tag having a plurality of layers and an equivalent resonant circuit containing an inductor and a capacitor is provided. The apparatus includes: a capacitor formed by a pair of conductive capacitor plates separated apart by a dielectric layer; an inductor connected to each of the pair of capacitor plates where an electromagnetic field of a preselected frequency at a first magnitude impinging upon the tag causes the equivalent resonant circuit to resonate and produce a detectable response from the tag; and, an electrically weakened area in the dielectric layer between the pair of conductive capacitor plates where the electromagnetic field at a second magnitude higher than the first magnitude impinging upon the tag causes a conductive path through the weakened area electrically connecting the pair of capacitor plates together and deactivating the tag.
