Abstract: A dielectric transducer for use in a sensor, actuator or generator comprising a plurality of layers of transducer foils, wherein an electrically contactable and conductive layer forming an electrode layer is applied to at least one side of each transducer foil. Expediently, at least two contact elements are provided, each of which is arranged at least partially in a recess or in a through-channel and extends over at least one layer of transducer foils, adjacent electrode layers being electrically conductively connected to different contact elements. Since adjacent electrode layers are connected to different contact elements, intended use is possible, and bringing together several contact lines is advantageously not necessary. Furthermore, the invention relates to a method for producing a multilayer dielectric transducer for use in a sensor, an actuator or a generator, as well as an actuator, a sensor or a generator.

Abstract: A method for warning about a wrong-way drive situation for a vehicle. The method includes at least reading in a wrong-way drive signal by an interface to a wrong-way drive detection unit. The wrong-way drive signal represents the wrong-way drive situation. The method also includes evaluating the wrong-way drive signal to determine a piece of role information. The piece of role information represents a role of the vehicle with respect to the wrong-way drive situation. The method furthermore includes generating at least one warning signal to warn about the wrong-way drive situation using the piece of role information. The at least one warning signal represents at least one role-dependent warning message. Moreover, the method includes providing the at least one warning signal at an interface to at least one output unit for outputting the at least one warning signal in the vehicle.
