The operating unit comprises an actuator, which mechanically excites an operating element. The actuator comprises a support strip made of a resilient material. Piezo elements, which are connected to the support strip in a shear-resistant manner, are located on both outer surfaces of the support strip. As a result of the alternate arrangement of the piezo elements, the support strip assumes an undulating form when moving out of its inactivated state. One side of the support strip is mechanically connected to the operating element and the other side is mechanically connected to a counterbalance. The support strip itself is mechanically fixed in the housing. In its inactivated state, the operating element and the counterbalance are at a different distance from one another than in the undulating activated state, wherein they move in opposite directions and thus lead to a compensation of dynamic forces acting on the housing.

Operating unit for a device, in particular for a vehicle component

A heating device is provided with plates stacked one on top of another. At least one first fluid channel is formed in a fluid-tight manner between a first plate package with a first and a second plate. An electrical heating element is arranged between a first plate of the first plate package and an additional plate. The electrical heating element is accommodated between the two plates in a sealed manner and is electrically insulated, wherein an inlet-side and an outlet side fluid connection of the first fluid channel is arranged on the second plate of the first plate package. The electrical heating element has a connection device for electrical contacting, which is connected to the electrical heating element and protrudes through a window in the second plate of the first plate package, wherein the fluid connections and the window are arranged adjacent to opposing lateral edges of the second plate.

Heating device

The application relates to an induction heating device having a housing and a fluid duct. The fluid duct is arranged in the housing and has a fluid inlet and a fluid outlet. Inside the housing is an induction element which generates an alternating magnetic field and which is separated from the fluid duct in a sealed manner by at least one wall. The device also includes at least one metallic areal heating element arranged in the fluid duct which can be heated by the alternating magnetic field.

A solar sensor for the detection of the direction of incidence and the intensity of solar radiation comprises a housing () made of a plastic material that is permeable to at least some of the solar radiation, the housing () having a curved side () facing the incident solar radiation and the housing () optically acting as a lens and having an internal focal plane () defined by the lens characteristics thereof. At least two photosensors () are embedded in the plastic material of the housing (), each photosensor () having a sensor area () sensitive to at least the part of the radiation to which the plastic material is permeable, and the sensor areas () of the photosensors () being arranged in a substantially common plane () located in front of or behind the focal plane (), seen from side () facing the incident solar radiation. The direction of incidence of the solar radiation is determinable based on the intensities of the solar radiation received by the sensor areas () of the photosensors ().
