  • Marking tape with passive resonant circuits and methods of use
    Patent number: 7563054
    Abstract: A marking tape comprising at least one resonant circuit, each resonant circuit comprising an inductive coil and a capacitor, forming a resonant circuit of a selected frequency, comprises inductive coils and capacitors formed by conductive material layers (2, 3, 4) on the surfaces of a dielectric plastic film (1) and is dimensioned to be wireless detected when positioned in a hidden location. Such marking tape can be produced with low cost and provide a wireless detection of the integrity of a marking tape in a hidden position, e.g. from the surface above a subterranean positioned marking tape.

  • Method of producing a deactivatable resonance tag for use in an electronic article surveillance system and a resonance tag so produced
    Patent number: 7023343
    Abstract: A method for producing a deactivatable tag is described including first short circuiting two opposite conductive layers at a predetermined place by using a heated tool applied on one of the layers, thereby permanently deforming such layer to produce a short, checking the quality of the short, and if the quality of the short is satisfactory, then connecting the two conductive layers with a crimp to obtain the desired frequency and finally removing the short by electrically or mechanically removing the short circuit to thereby bring the tag in the desired form ready for use and deactivation.
