Abstract: An interactive display unit for presenting information and for interacting with a user, in particular in a vehicle interior, includes at least one imaging cell including a photorefractive polymer material layer between two transparent substrate carriers in a sealing arrangement. Each substrate carrier includes a transparent electrode layer that faces the photorefractive polymer material layer. A writing light source with a propagation oriented in the direction of the photorefractive polymer material layer is arranged on one of the substrate carriers in a parallel manner with respect to the substrate carrier. A haptic sensor/actuator unit is arranged on the other substrate carrier, and at least one reading light source with a propagation oriented in the direction of the photorefractive polymer material layer is arranged in a lateral manner.

Abstract: A display device for a vehicle displays image information that can be seen by at least one vehicle occupant. A lighting unit and a display unit are provided, the lighting unit being designed as at least one laser, and at least some sections of the display unit being formed from at least one electro-active polymer and/or from a chromogenic material. A method is also provided for operating a display device.

Abstract: A component for a vehicle, includes at least one component part, which is made of a magnetically active foam material and/or a foam material which can be magnetically activated and/or a dielectric elastomer. The component is at least partially or completely laterally delimited so that the component elastically expandable in at least one degree of freedom. The component can be a switch element, a transducer, an active muffler, and/or an energy conversion element.

Abstract: An electronic status detection device for wireless detection of at least one status of an apparatus, wherein the status detection device comprises at least two resonant circuits, of which at least one resonant circuit is active and one resonant circuit is passive, wherein the active resonant circuit comprises at least one control device. A status detection device such as this makes it possible, for example, to reliably detect the presence or the absence of belt clips in safety belt locks.
