Abstract

The invention relates to an electrical circuit arrangement for generating signal events for initiating or carrying out switching, adjusting or releasing processes. According to the first invention aspect, the inventive electric circuit arrangement comprises an input component for carrying out a selection process for generating an input event and a switching component for generating a switching signal according to the input event evaluation, wherein said input component is constructed in such a way that, in framework of said selection process, the input event is injected into the user actuating the switching component on the base of the interactive effect of electric fields and said switching component is provided with an interface device for detecting the input event injected into the user or acting therein, the input component and the interface device are placed in the operating position in such a way that the signal transmission therebetween is carried out in a signal transmission path integrating the user when it actuates the input component, thereby making it advantageously possible to transmit the user input operation indicative signals to the switching component through said user, wherein said transmission can be carried out only when the user actually initiates an input and thereby can be used in the form of a signal transmitting medium.

Claims

1. An electric circuit arrangement compromising:

an input component for bringing about a selection operation for generation of an input event, and

a switching component for generation of a switching signal by signal-processing evaluation of the input event,

wherein the input component is designed in such a way that, during the selection operation, the input event is coupled on the basis of electric field interaction effects into a user who actuates the input component, and the switching component includes an interface device for detecting the input event coupled into the user,

wherein the input component and the interface device are so disposed in service position that the signal transmission between the input component and the interface device takes place with incorporation of the user in a signal-transmission path, when the user actuates the input component.

2. A circuit arrangement according to claim 1, wherein the input component compromises an input panel for processing a range selection.

3. A circuit arrangement according to claim 1, characterized in that the input component compromises one of a number and character pad.

4. A circuit arrangement according to claim 1, wherein the input component comprises a positioning knob device.

5. A circuit arrangement according to claim 1, wherein the input component comprises a display device.

6. A circuit arrangement according to claim 1, wherein the input component is designed as a freely installable, substantially flat input surface element.

7. A circuit arrangement according to claim 1, wherein the input component is designed as a foil structure.

8. A circuit arrangement according to claim 1, wherein the input component is equipped with an adhesive back.

9. A circuit arrangement according to claim 1, wherein the interface device is integrated in one of a seat device, a steering-wheel device, and a door handle device.

10. A circuit arrangement according to claim 1, wherein the input component compromises an electrode device and an electronic circuit connected thereto, and in that an electric field is modulated according to a date pattern and coupled into the user via the electrode device in the zone of a selection portion.

11. A circuit arrangement according to claim 10, wherein the electrode device is grounded in modulated manner via the electronic circuit.
