  • Marker for mechanically resonant article surveillance system
    Publication number: 20070080808
    Abstract: A magnetomechanical resonance element or marker strip with facilitated performance based on an amorphous magnetostrictive alloy ribbon is utilized in an electronic article surveillance marker. A curvature along the element's length direction is introduced during ribbon fabrication with a different radius of curvature, which increases the resonance performance with minimal loss in the magneto-mechanical circuit, and more particularly, in a marker utilizing a plurality of resonating elements or marker strips. A marker is fabricated utilizing the resonance element or elements and is utilized in an electronic article surveillance system.
    Type: Application
