Abstract: A method is provided for producing an arrangement, which, for example, may be used for further processing into a non-contact chip card or an identification document and which comprises a multi-layer structure, with a first part of an RFID antenna, at least comprising a coil-shaped antenna structure and a connecting structure, being arranged on a carrier layer and the chip being directly mounted on this part of the antenna structure and contacted, with a compensation layer being arranged thereabove, which in the area of the chip comprises an embedding opening and which comprises at least two contacting openings in the intersection area of the first part of the RFID antenna with a bridge structure, which is located on a cover layer, and subsequently the individual layers being connected to each other via lamination.

Abstract: A magnetic-guiding laminate is used to improve wireless communication between a transmitter and a receptor disposed on a substrate, regardless of the substrate materials. The laminate can comprise one or more layers of magnetic or non-magnetic material with different magnetic property. For example, the laminate can comprise a paramagnetic layer disposed on a diamagnetic layer, where the paramagnetic layer attracts the magnetic field toward the RFID antenna, and the diamagnetic layer prevents the magnetic field from dispersing in the substrate. Alternatively, the laminate can comprise multiple paramagnetic layers, wherein at least two layers have different magnetic properties, such as different permeability values.

Abstract: A method for producing a security layered construction as well as a security layered construction for an identification document (61), particularly for personal identification, having a transponder layer (20) and at least one cover layer (38, 39), the transponder layer being covered using the at least one cover layer to form a seal with the wire conductor positioned interposed, and at least one viewing side (62) of the at least one cover layer or transponder layer being provided with security printing (63).

Abstract: A holding tool for fixing an electronic component (2) during a manufacturing process, the electronic component (2) comprising a winding assembly (20) and an electronic circuit (24), wherein the holding tool (1) includes a holding tool body (10), first and second jaws (12, 14) disposed at the holding tool body (10) relatively movable to each other in a first direction (A), and first and second wire guide means (3, 4) characterized in that the first and second wire guide means (3, 4) are disposed at the holding tool body (10) remote from the jaws (12, 14).

Abstract: The method enables authentication data to be communicated and checked between a transponder device (1) and a reader unit (2) of a vehicle in order to authorize access to the vehicle. The device includes a logic circuit (11), a non-volatile memory (13), an encryption and/or decryption circuit (12) and a first transmission and reception module (14, 16) of data signals (SD). The reader unit includes a microprocessor unit (21), a memory (22), a random number generator (24) and a second module (23, 25) for transmitting and receiving data signals (SD). A random number (RN1) generated in the reader unit is transmitted with a first encrypted function obtained using the random number and a secret key. The transponder device receives the random number and the first encrypted function. A new first encrypted function is calculated in the transponder device using a secret key identical to the secret key of the reader unit. This new first function is compared with the first received encrypted function.

Abstract: An inductive signal transmission device including a transponder circuit (1) having at least one first coil, and an interrogation circuit (3) having at least one second coil (4). The transponder circuit is placed on an object (5) capable of rotating about at least one rotational axis (9) passing through the object. The interrogation circuit is placed on a structure, which can be stationary, to which the object is connected. A coupling coil (2), provided with at least one turn describing a ring, is mounted on the structure or the object coaxially to the rotational axis of the object. This coupling coil acts as the inductive coupling interface between the first coil and the second coil such that the inductive signal transmission is independent of the rotation of the object. The transponder circuit is of the passive type and includes at least one sensor for measuring a physical parameter.
