Abstract: The present invention relates to microchip cards which are capable of operation both as a contactless card and as a contract card. The card is provided with a coil that prevents any piracy thereof through voltage peaks.

Abstract: A Method and device for recognizing card terminals which include a plurality of chip cards wherein each chip card includes a plurality of function components, recognizing circuit, and electronic circuitry with contactless connection. The card terminals differ from one another by emitting electromagnetic waves having different physical properties. When a chip card recognizes a particular terminal, a specific function component is activated according to the particular terminal.

Abstract: A method for calibrating a device for non-contact position measurement wherein a movable part subject to positional identification is provided spatially proximate to a sensor carrier that includes a plurality of signal generators electrically and spatially separated from one another in order that the position of the moving part can be identified via voltage signals therefrom. To obtain an unequivocal characteristic of the positional voltage distribution, only defined signals such as a zero value signal or other characteristic value, have length values signed to them and neighboring voltage values are coemployed to obtain an unequivocal position identification.

Abstract: A noncontacting signal and energy transmission device includes a stationary microstation and a moveable microunit, wherein data is transmitted between the microstation and the microunit simultaneously by phase shifted signals and by synchronously switched signals, which also supply power to the microunit.
