Abstract

A vehicle window, includes at least one transducer device and transducer electronics associated with the transducer device, wherein both the transducer device and the transducer electronics are arranged at least partially within the vehicle window, wherein the transducer device and/or a compensating device associated with the transducer device and arranged at least partially within the vehicle window and/or an electrical shielding device associated with the transducer device for electrically shielding the transducer device relative to a vehicle interior or a vehicle exterior are transparent, at least in sections.

First claim

1 . A vehicle window, comprising at least one transducer device and transducer electronics associated with the transducer device, wherein both the transducer device and the transducer electronics are arranged at least partially within the vehicle window,
wherein
the transducer device and/or
a compensating device associated with the transducer device and arranged at least partially within the vehicle window and/or
an electrical shielding device associated with the transducer device for electrically shielding the transducer device relative to a vehicle interior or a vehicle exterior

are transparent, at least in sections.

2 . The vehicle window according to claim 1 , wherein the transducer electronics include a signal conditioning and/or signal processing component.

3 . The vehicle window according to claim 1 , wherein the transducer device and the transducer electronics have a distance of less than 5 cm from one another.

4 . The vehicle window according to claim 1 , wherein the electrical shielding device is electrically isolated or is held at earth potential or at a supply voltage or at some other reference potential.

5 . The vehicle window according to claim 1 , wherein the electrical shielding device is arranged on an inner side or an outer side of the vehicle window.

6 . The vehicle window according to claim 1 , comprising at least one transducer device and the electrical connection lines associated with the transducer device, wherein the electrical connection lines have, at least in sections, an increased distance from one another,
wherein the increased distance is achieved in that the connection lines are moved away from one another, in sections, over their course and/or in that at least one connection line is in contact with a conductive section of the transducer device at a distance from one end of the respective section, and/or
wherein the increased distance is at least 2 mm.

7 . The vehicle window according to claim 1 , wherein the transducer device and/or the transducer electronics and/or the compensating device and/or the shielding device is/are arranged, at least partially, between two layers of the vehicle window arranged one above the other.

8 . The vehicle window according to claim 1 , wherein the transducer device comprises a sensor.

9 . The vehicle window according to claim 8 , wherein the sensor is transparent and can be configured at any position and/or with any size.

10 . The vehicle window according to claim 1 , wherein the transducer device and/or the compensating device and/or the shielding device comprises/comprise at least one electrically conductive layer and/or the transducer device and/or the compensating device comprises/comprise at least two electrically conductive layers, wherein the two electrically conductive layers are isolated from one another and are arranged in one plane or in different planes and/or
wherein the transducer device and/or compensating device comprises/comprise a capacitor.

11 . The vehicle window according to claim 1 , wherein the transducer device and/or the transducer electronics and/or the compensating device and/or the electrical shielding device and/or the electrical connection line(s) are produced at least partially by coating and/or printing and/or depositing and/or patterning and/or by inserting a previously coated and/or patterned insert.

12 . The vehicle window according to claim 1 , wherein the vehicle window is a vehicle window pane.

13 . A vehicle including a vehicle window according to claim 1 .

14 . A method for producing a vehicle window according to claim 1 , comprising:
providing the two individual panes to be arranged one above the other and an intermediate layer to be arranged therebetween; printing a transparent, conductive ink layer for forming the sensor on at least one side of the intermediate layer; contacting the transparent, conductive ink layer with an electrical conductor; and superimposing and laminating the individual panes and the interpositioned intermediate layer for forming the vehicle window.

15 . The method according to claim 12 , wherein the printing of the transparent, conductive ink layer is done by an ink jet printing method or a screen printing method.

16 . The vehicle window according to claim 2 , wherein the signal conditioning and/or processing component is an amplifier and/or a driver and/or a converter, and/or a signal processor and/or a microcontroller.

17 . The vehicle window according to claim 5 , wherein the electrical shielding device is arranged at least partially overlapping the transducer device.

18 . The vehicle window according to claim 6 , wherein the increased distance is at least 10 mm.

19 . The vehicle window according to claim 7 , wherein the transducer device and/or the transducer electronics and/or the compensating device and/or the shielding device is/are arranged, at least partially, between two individual panes of the vehicle window arranged one above the other.

20 . The vehicle window according to claim 12 , wherein the vehicle window is a windshield.
