Abstract: An operating apparatus for a vehicle component comprises an operating panel (12) as well as an electric motor (34) mechanically coupled thereto with an unbalance mass. A detector (20) can capture the contact of the operating panel (12) by a user. A sensor (46) is provided in order to set exactly the number of revolutions of the electric motor in response to the contact of the operating panel by a user. The number of revolutions of the rotor is determined via this sensor.

Abstract: A device for detecting steering wheel contact comprises at least a first electrode (12) which is provided in a steering wheel (10) and which forms, together with a human body acting as a second electrode and a dielectric situated therebetween, at least one sensor capacitor (26). The device also comprises an evaluation circuit (24) having a reference capacitor (30) of known capacitance which can be connected parallel to the sensor capacitor (26), a direct current voltage source (34) which can be connected to the reference capacitor (30), and a measuring device for measuring the voltage at the reference capacitor (30).

Abstract: An operating system for a motor vehicle has an operating surface with at least one operating area that is indicated by a symbol system on the operating surface, a touch sensor system by means of which a touch of the operating area is detectable, a drive for generating a haptic feedback by a movement of the operating surface, a drive frame which connects the drive to the operating surface in a force-transmitting manner, and an operating system carrier relative to which the operating surface is movable for generating the haptic feedback. An elastically pretensioned mounting is provided between the drive frame and the operating system carrier.

Abstract: The invention relates to a collet chuck for clamping a dental tool, wherein the collet chuck has at least temporarily a mechanical stress applied to it and is made of steel. The collet chuck according to the invention is characterized in that the steel, at least in a surface layer, has a nitrogen content of at least 0.1 wt %.

Abstract: A clamping device for a dental tool in a dental turbine handpiece having at least one clamping lever. The clamping lever permits a tool shank to be clamped. The structure allows for more accurate relative positioning and improved concentricity of the dental tool after clamping.

Abstract: A clamping device for a dental tool in a dental turbine handpiece having at least one clamping lever that is supported in a fulcrum and that extends along the axis of a tool shank to be clamped, wherein the clamping lever is designed and arranged such that the tool shank can be clamped using the clamping lever and that on rotation of the clamping device, through the effect of the centrifugal force, the clamping lever is radially deflected about the virtual fulcrum, so as to increase the clamping force acting on the tool shank.

Abstract: A steering device for a motor vehicle includes an actuating member for the introduction of the steering movement and a steering linkage to transfer the steering movement to the vehicle wheels. The actuating member consists of a steering wheel (1) which is rotatable about a small angle and of a measured value transmitter (2) to generate an electrical or electronic position signal. The steering linkage is actuated by an adjustment drive which is controllable by an electrical regulating device as a function of the position signal.

Abstract: A steering device for a motor vehicle, with an actuating member for the introduction of the steering movement and with a steering linkage to transfer the steering movement to the wheels. The device is characterized in that the actuating member consists of a “steering wheel” (1) which is rotatable about a small angle and of a measured value transmitter (2) to generate an electrical or electronic position signal, and that the steering linkage is actuated by an adjustment drive which is controllable by an electrical or electronic regulating device as a function of the position signal.
