Abstract: The invention relates to a heatable touch sensor and a steering wheel. It has an optical waveguide which is connected to an electrical heat conductor. The optical waveguide changes its transmission behavior, which is determined, with a change in position or bending. The heat conductor is a resistance heater which emits heat by applying an electrical voltage and by the associated current flow. The touch sensor operates by means of optical interferometry, which enables a very high sensing accuracy.

Abstract: A component with an integrated occupant contact identification and a heating function having at least one evaluation and control unit and at least two electrical conductors, which are powered independently of one another and which are assigned to various regions of the component, wherein the evaluation and control unit spatially detects an occupant contact of the component by evaluating a change in capacitance of the electrical conductors, wherein the evaluation and control unit increases the electric energy in the assigned electrical conductor based on a detected occupant contact. A method for identifying an occupant contact of a component.

Abstract: A method for displaying in a transportation vehicle braking operations of transportation vehicles driving ahead wherein the transportation vehicles driving ahead are detected; data are collected on the acceleration of the transportation vehicles driving ahead; and, from the data on the acceleration, first transportation vehicles driving ahead with a first acceleration are determined, the first acceleration being a negative acceleration, the magnitude of which is greater than or equal to a specified threshold value. On a display area, first graphical objects are generated, each first transportation vehicle driving ahead being assigned a first graphical object which indicates that the first transportation vehicle driving ahead assigned to the first graphical object has the first acceleration. Also disclosed is a device for displaying accelerations of transportation vehicles driving ahead in a transportation vehicle.
