Abstract: The present invention relates to an identification element having an integrated circuit and an antenna coil connected to the integrated circuit. The antenna coil comprises a lower conducting track and an upper conducting track. Each track includes a plurality of turns, with the two tracks being arranged on either side of a dielectric layer. The relative position of the two tracks is such that they overlap substantially only in one selected area or in two selected areas.

Abstract: The invention is directed to an identification element (8) having an integrated circuit (6) and an antenna coil (7) connected to the integrated circuit (6) (→RFID transponder).

Abstract: The present invention relates to a security element for electronic article surveillance, comprising two at least partially overlapping layers of conductor strips interconnected by a dielectric adhesive coating. This arrangement reduces the risk of reactivation after activation is once effected. To achieve this, the upper layer and the lower layer of conductor strips have at least one turn, and that the strength of the two layers of overlapping conductor strips is so high as to cause the security element to bend, if subjected to mechanical strain, in those areas which are essentially devoid of conductor strips.

Abstract: The present invention relates to a security element for electronic article surveillance, having one lower and one upper conducting track with at least one winding each, the two conducting tracks being wound in opposing directions and overlapping in at least one area of overlap, and a dielectric layer in the area of overlap between the two conducting tracks. In a critical area in which a border edge of the lower and upper conducting tracks overlap, the dielectric layer is thicker than in the remaining area of overlap. The present invention also relates to a method of manufacturing such a security element.

Abstract: The present invention is directed to a method and an identification element (8) comprising an integrated circuit and an antenna coil disposed on a substrate. With respect to the identification element, it is proposed that the conducting track/conducting tracks of the antenna coil be die-stamped from an aluminum foil, that terminal pads referred to as bumps projecting from the undersurface of the integrated circuit be formed on the contacts of the integrated circuit, and that at least in the area of the bumps provision is made for a substance which, as a result of a defined volume reduction occurring during curing, produces a compressive and/or tensile force between the integrated circuit and the substrate so that the bumps are connected to the antenna coil by a press contact.

Abstract: An electronic anti-theft element consists of at least one spiral printed circuit, a capacitor and a dielectric layer arranged therebetween, or of two spiral printed circuits which are arranged on respective sides of a dielectric layer in an at least partially overlapping manner (forming resonant circuit). The object of the invention is to provide a resonant circuit which is less liable to be reactivated. For that purpose, in at least one selected area (a rated break point) of the dielectric layer a short-circuit is created between the opposite capacitor plates or spiral printed circuits when a sufficiently high energy is supplied by a magnetic alternating field. The selected area is locally reinforced, preventing the suppression of the short-circuit by mechanical stress and the reactivation of the anti-theft element.

Abstract: A resonant circuit for an anti-theft element consists of two spiral printed circuits and one dielectric layer. The spiral printed circuits are wound in opposing directions and arranged on opposite sides of the dielectric layer so that they at least partly overlap. At least one selected area is provided in which a conductive path arises between the two spiral printed circuits whenever a sufficiently high energy is applied by means of an external alternating field.

The present invention provides an economically priced identification element and a method of manufacturing such an identification element. The integration circuit is a non-encapsulated chip and the antenna coil comprises at least one layer of a metallic coating.

Abstract: The present invention relates to a universal anti-theft device for securing articles against theft, which has at least one electromagnetic resonant oscillating circuit (2) that, in the interrogation field of an article monitoring system, is excited to transmit a characteristic signal which subsequently trips an alarm and at least one further electromagnetic resonant oscillating circuit which contains specific, encoded information about the article. The present invention also relates to a method for producing the universal anti-theft device for securing articles against theft.

Abstract: The invention is directed to an electronic labelling system such as for display pricing information on the edge of shelves in retail supermarkets which system comprises a computer (1), a transceiver (2) connected thereto, as well as electronic tags (4) preferably fixed to shelves, with the transceiver (2) transmitting, by means of electromagnetic waves (5), communications frames to update the tags (4), said frames holding the specific address (7) of a tag (4) as well as the data (8) to be displayed, said tags (4) including a receiver which is periodically activated to receive the communications frames. To reduce the power consumption of the tags (4), it is suggested that the tags (4) comprise devices for synchronizing the receivers, said devices activating the receivers at the same instant in time when a communications frame is being transmitted from the transceiver (2).
