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.

Abstract:
A magnetic detacher has a core magnet and a ring magnet. The core magnet has a body with a top and bottom surface, and produces a first magnetic field. The ring magnet defines a cavity. The ring magnet has a body with a top and bottom and produces a second magnetic field. The ring magnet is axially aligned with the core magnet such that the first magnetic field opposes the second magnetic field along the bodies and enhances it within the cavity. The top surface of the core magnet is separated from the bottom surface of the ring magnet by a predetermined distance thereby producing a resultant magnetic field having a first resultant field strength at a specific position greater than a second resultant field strength produced at the same position when the top surface of the core magnet abuts the bottom surface of the ring magnet.
Magnetostrictive Element Having Optimized Bias-Field-Dependent Resonant Frequency Characteristic
A magnetostrictive element for use in a magnetomechanical marker has a resonant frequency characteristic that is at a minimum at a bias field level corresponding to the operating point of the magnetomechanical marker. The magnetostrictive element has a magnetomechanical coupling factor k in the range 0. 28 to 0. 4 at the operating point. The magnetostrictive element is formed by applying current-annealing to an iron-nickel-cobalt based amorphous metal ribbon, or by cross-field annealing an iron-nickel-cobalt alloy that includes a few percent chromium and/or niobium.
Disc Device Having A Magnetic Layer Overweighing The Information Signal Pattern For Electronic Article Surveillance
A disc device includes a disc substrate having an information signal pattern formed on a surface thereof and a magnetic material layer formed on the information signal pattern which permits for detection of the device by an electronic article surveillance detection system.
Eas Marker With Flux Concentrators Having Magnetic Anisotropy Oriented Transversely To Length Of Active Element
A harmonic-type electronic article surveillance marker includes a thin, elongated active element and flux concentrators provided at the ends of the active element. The flux concentrators have magnetic anisotropies that are oriented perpendicular to the length of the active element. The orientation of the magnetic anisotropies and the anisotropy field of the flux concentrators stabilize the switching threshold of the marker. The switching threshold level can be controlled by varying parameters such as the angle of the magnetic anisotropies relative to the length of the active element, the strength of the anisotropy field of the magnetic anisotropies, and the geometry of the active element and the flux concentrators.
Deactivatable/Reactivatable Magnetic Marker Having A Step Change In Magnetic Flux
A marker for use in an electronic article surveillance system in which the marker comprises a magnetically soft component and exhibits a pinned wall hysteresis characteristic with a step change in flux at a threshold value of applied field and in which the marker further comprises a magnetically hard or semi-hard component integral with the soft component and whose magnetic state can be switched between activating and deactivating states to switch the marker between active and deactive states.

Abstract:
A security system tag. The security system tag includes a housing. The security system tag further includes an electronic article surveillance, EAS, element in which the EAS element is arranged to emit a detectable signal when introduced to an interrogation signal. The security system tag further includes a metal element in which the metal element is adapted to be heated. The security system tag further includes a first reversible adhesive proximate the metal element in which at least a portion of the first reversible adhesive de-bonds when thermally affected by the metal element when the metal element is heated.
