  • Publication number: 20240190249
    Abstract: A user control with haptic feedback on a 3-dimensional touch surface is provided. The control includes a 3-dimensional touch surface to be touched by a user with an electrode structure arranged at least partly on it. The electrode structure is configured to provide the haptic feedback to the user based on electro-adhesion between the user and the control. The user control with haptic feedback on a 3-dimensional touch surface is electrically contacted using a contacting surface, on which an anisotropic conducting film layer and a flexible printed circuit are arranged.

  • Patent number: 11995239
    Abstract: A display unit comprising a touch surface touchable by a user, a drive unit for moving the touch surface when the touch surface is touched, in particular for haptic feedback to the user, and at least one damping element, which damps mechanical oscillations of the movement of the touch surface. Each damping element comprises an elastic element and a pressure setting element (for example, a valve). This pressure setting element is designed to fill the elastic element in a variable or settable manner with gas for the damping. The damping properties of the display unit can thus be set arbitrarily via the gas pressure inside the elastic element.

  • Publication number: 20240134476
    Abstract: A sensor unit including a housing and a contact element movably mounted along a first axis and configured to come into contact with a touch display surface. The contact element is moved along the first axis when coming into contact with the touch display surface. An acceleration sensor is movably mounted in the housing at least along the first axis. A biasing element is located on one side of the acceleration sensor and configured to bias the acceleration sensor in one of two directions along the first axis. The contact element is movably mounted on the other side of the acceleration sensor opposite the biasing element and is coupled to the acceleration sensor to move the acceleration sensor against the bias of the biasing element in the other of the two directions along the first axis when contacting the touch display surface.

  • Publication number: 20230173981
    Abstract: An electronic mirror comprises a liquid crystal cell, wherein the liquid crystal cell comprises a first transparent electrode, a second transparent electrode, a liquid crystal layer comprising liquid crystal molecules arranged between the first transparent electrode and the second transparent electrode, and an AC voltage source configured to apply an alternating voltage across the liquid crystal layer between the first transparent electrode and the second transparent electrode, wherein, when a voltage is applied across the liquid crystal layer, the liquid crystal molecules in the liquid crystal layer change their orientation, and the electronic mirror is configured to apply a varying voltage across the liquid crystal layer which gradually decreases from outer areas towards the center of the liquid crystal layer such that the refraction index of the liquid crystal layer gradually varies from outer areas towards the center of the liquid crystal layer.
