Abstract: A man-made, flexible, knitted member is formed from at least one continuous strand of a conventional knittable flexible material knitted in a tubular or circular form with at least two sets of interlocked stitches extending longitudinally along opposite sides of the tubular form with opposite ends of the stitches of each row of each set being connected by unstitched lengths of the strand material to the ends of stitches of adjoining rows of the remaining set. A planar member is made by flattening the original tubular form longitudinally through both sets of stitches. The resulting structure is thicker at both ends due to the overlap of the strand material in the stitches and thinner between the end where the unstitched length of the strand material is provided. When flattened, the structure has a ladder-like appearance with interlocked stitched portions forming side rails of the structure and unstitched lengths of the strand forming a rung portion of this structure interconnecting the side rail portions.

Abstract: A security tag used with an electronic article surveillance system for detecting the presence of the tag within a surveilled area utilizing electromagnetic energy at a frequency within a predetermined detection frequency range includes a dielectric substrate having first and second opposing principle surfaces and a resonant circuit capable of resonating at a frequency within the predetermined detection frequency range. The resonant circuit includes an inductor formed at least in part on one of the principal surfaces of the substrate. A first perforation path formed of a series of spaced apart perforations extends along a line across the substrate and through at least a portion of the inductor such that a stress exerted on the tag breaks the tag and the inductor along the first perforation path, causing an open circuit condition which prevents the resonant circuit from resonating.
