Abstract: An identification/surveillance device including a tag portion and a tack. The tack includes a button and a pin having a dull end and a sharp end. The identification/surveillance device is secured to an article to be identified/surveilled by inserting the pin through the article and engaging the pin with the tag portion. The dull end of the pin is releasably engaged with either the button or the tag portion such that when the identification/surveillance device is removed from the article the sharp end of the pin remains engaged with either the tag portion or the button and only the dull end of the pin is exposed.

Abstract: A magnetostrictive element for use in a magneto-mechanical 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 cross-field annealing to an iron-rich (Fe) amorphous metal alloy (100) ribbon (45 to 82 percent iron) which includes a total of from 2 to 17 percent of one or more of Mn, Mo, Nb, Cr, Hf, Zr, Ta, V. Cobalt (Co), nickel (Ni), boron, silicon and/or carbon may also be included. The metal alloy (100) may include one early transition element selected from the group consisting of Zr, Hf and Ta, and also a second early transition element selected from the group consisting of Mn, Mo, Nb, Cr, and V.

Abstract: A magnetomechanical EAS marker (20) is formed of a housing (22, 24), a magnetostrictive active element (12) in the housing and a bias element (not separately shown) fixedly mounted on the housing. A central portion of the active element is secured to the housing to keep the active element from shifting in a longitudinal direction relative to the bias element and to keep ends of the active element spaced from the housing. The active element remains free to mechanically resonate in response to an EAS interrogation signal. The stable positioning of the active element prevents variations in the bias magnetic field due to shifting relative to the bias element, while keeping ends of the active element free from frictional damping due to mechanical loading from contact with the housing.

Abstract: 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 single deactivation device (10) is used to deactivate both harmonic type E AS markers and magnetomechanical type EAS markers. The deactivation device includes a housing (12), a permanent magnet (14) and a coil (16) disposed within the housing. The coil is circular and is arranged concentrically with , and outside of, the permanent magnet. The permanent magnet forms a DC magnet ic field for deactivating the harmonic type marker by magnetizing control elements thereof. The coil is driven to generate an AC magnetic field that deactivates the magnetomechanical type marker by degaussing a control elemen t thereof. The maximum amplitude of the AC magnetic field is lower than the level of the DC magnetic field, and is substantially below the coercivity of the control elements of the harmonic type marker. The coercivity of the control element of the magnetomechanical type marker is low enough to be degaussed by the AC magnetic field.

Abstract: 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.
