    摘要: A contactless integrated circuit is provided that includes a RFID communication interface, a UHF communication interface, a data processing unit, an interface multiplexer, a communication mode detection circuit, a first modulation and demodulation circuit, a second modulation and demodulation circuit, and a multiplexer demultiplexer circuit. The interface multiplexer couples the data processing unit to the RFID or UHF communication interfaces. The multiplexer demultiplexer circuits are driven by mode signals delivered by the communication mode detection circuit, to link the data processing unit to one of the two modulation and demodulation circuits.

    摘要: The present invention relates to a device (40) comprising a combination of at least two contactless integrated circuits (45), each integrated circuit being connected to an individual antenna coil (46) to send and/or receive data by inductive coupling. According to the present invention, the device comprises a collective antenna coil (42) that is larger in size than the individual antenna coils of the integrated circuits, and means (41) for arranging the individual antenna coil of an integrated circuit proximate to the collective antenna coil, at least when data are to be read and/or written in the integrated circuit, so that the individual antenna coil of the integrated circuit is inductively coupled to the collective antenna coil. Application to smart cards, electronic badges or electronic labels.

    摘要: The system comprises firstly an electronic label and, secondly, a label reader. The label comprises a foil made of a material that conducts magnetic fields and has a low coercive field. It is placed against the antenna and is parallel to the antenna to form a shield and a flux concentrator for the electromagnetic waves. The reader comprises bars surrounded by coils to generate a magnetic field so that the lines of said magnetic field can get looped in passing into the label when the reader is placed in the vicinity of this label. If the object on which the label is placed is provided with a protective cup, the invention provides for positioning plates, made of a material similar to that of the foil, between the bars and the protective cup. Application to the remote identification of objects, in particular metal objects such as gas cylinders.
