Abstract: An optical device usable as a headlight of a motor vehicle has an optical system in the form of a lens and/or a light source which is surrounded by a housing and which is covered by a translucent, in particular transparent, cover which is connected to the housing. To increase the functionality of the optical device, a PTC heating assembly is configured to heat a space between the housing and the cover. The PTC heating assembly includes at least one PTC element and strip conductors that are connected electrically to the PTC element.

Abstract: An electric heating device includes at least two hollow profile elements which form a fluid channel for a fluid to be heated and, opposite the fluid channel, a heating chamber which is bounded by opposite contact surfaces against which at least one PTC element abuts in a heat-conducting manner. A scalable and easier to assemble electric heating device is achieved by connecting the hollow profile elements to one another by complementary form-fit segments.

Abstract: A method for the production of a heat-generating element includes placing in which at least two electrical conductor elements, provided with through holes, onto a film provided with an adhesive mass, pressing the conductor elements against the films such that the mass is forced into the through holes. At least one PTC element is subsequently placed onto one of the conductor elements, and then the other of the conductor elements, together with the film adhering thereto, is placed opposite to the one of the conductor elements onto the PTC element. The invention further relates to a heat-generating element with a PTC element and electrical conductor elements connected thereto in an electrically conductive manner for energizing the PTC element with a different polarity and an electrical insulation that is provided on the outer side thereof with a film and an adhesive mass applied thereto.

Abstract: A PTC heating element has a casing that joins as a unit at least one PTC element, conductor paths electrically connected to the PTC element, and insulating layers bearing, in a heat-conductive manner against the PTC element. The PTC heating element also has contact strips which project over itself and which are electrically conductively connected to the conductor paths for energizing the PTC element with different polarities. The casing forms a receptacle space that receives the PTC element, the conductor paths, and the insulating layers. In order to improve heat decoupling from the PTC element, the receptacle, in a cross-sectional view, is defined by two oppositely disposed inner surfaces covering the PTC element and concave cavities, adjoining the inner surfaces and forming the longitudinal edges of the casing, the diameter of which is greater than the distance between the inner surfaces. The electric heating device has at least one PTC heating element arranged in a circulation chamber.

Abstract: An electric heating device, in particular for a motor vehicle, includes a housing which has an inlet and outlet opening for a medium to be heated and which encloses a layered structure. The layered stricture comprises at least one PTC element which is electrically conductively connected to conducting elements leading to connections of different polarity, and heat-emitting elements that are conductively connected on both sides to the PTC element. In order to provide improved heat dissipation, the heat-emitting elements include a panel element that is provided with perforations and that is made of a heat-conducting material.

An oil reservoir is arranged in the housing interior for storing oil, which fluidically communicates with an oil reservoir line for conducting oil out of the oil reservoir, and a fluid cell valve device for closing and opening the raw oil line, the clean oil line, and the oil reservoir line.

Abstract: A mobile device comprises a functional arrangement for performing a function of the mobile device, a coupling device for connecting the mobile device to a stationary device, an authentication device for authenticating the stationary device and an activation device. The authentication device authenticates the stationary device based on information on the stationary device. The activation device activates the functional arrangement when the mobile device is connected to the stationary device by the coupling device, and when the stationary device has been authenticated by the authentication device.

Abstract: A device includes an offset subtraction unit; an image sensor which receives, for each of a plurality of bright frames, a respective image signal obtained during a respective exposure time of the image sensor, and transmits the same to the offset subtraction unit, and receives, for a dark frame, a respective image signal obtained during a respective exposure time of the image sensor, and transmits the same to the offset subtraction unit; and a control unit which ensures that the image sensor alternately transmits a number of bright frames and one dark frame to the offset subtraction unit. An amount of light by which the respective image signal for each of the bright frames is generated is larger than an amount of light by which the respective image signal for the dark frame is generated; and the offset subtraction unit obtains an offset and subtracts the offset from a signal.

Abstract: A membrane humidifier has a housing and a membrane stack. The membrane stack includes two first stack sides aligned parallel to the assembly direction.
