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.

A magnetic ribbon or sheet is coated with an electrical insulator prior to formation of a magnetic implement. Manufacture of the magnetic implement is accomplished in a single process without need for co-winding magnetic and insulator ribbons. Thermal property differences between the magnetic material and the insulator operate during heat treatment to enhance magnetic property modification of the implement.

A bearing includes a first race in operational contact with a shaft, a second race in operational contact with the first race, and a third race in operational contact with the second race. The first, second and third races cooperate to define an aperture therethrough to the shaft. A connector is disposed through the aperture to functionally interlink the first race, the second race and the shaft to insure that the first race and the second race rotate substantially with the shaft. In operation, the first and second races define a first bearing surface that accommodates angular displacements of the shaft, and the second and third races define a second bearing surface that accommodates axial and rotational movements of the shaft.
