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 device for generating a haptic moment at an actuator including an unbalance motor, a sensor for sensing activation of the actuator, and a processor for generating an actuation signal for the unbalance motor depending on signals of the sensor, wherein the processor is embodied so that, when activation of the actuator is sensed, the processor generates a first actuation signal and generates a second actuation signal, wherein the first actuation signal is configured so the unbalance motor is accelerated in a first rotational direction without reaching more than two revolutions, and the second actuation signal is configured so the unbalance motor is braked without the unbalance motor starting to move in the second rotational direction.
