Abstract: A heat discharge device having a bottom plate having a bottom and an upper surface. Heat discharge blades extend between two front faces of the bottom plate and inclinations of the heat discharge blades are configured in a way such that neighbouring heat discharge blades alternatingly approach one another and move away from each other. Neighbouring heat discharge blades are connected to one another at the end regions facing away from the upper surface of the bottom plate directly and delimit a first air flow channel. Neighbouring heat discharge blades delimit a second air flow channel, which is open at the side facing away from the upper surface of the bottom plate. The heat discharge blades have a group of air vents, wherein the first air flow channels are open at the opposite distal ends thereof and the second air flow channels are closed at the opposite distal ends thereof.

Abstract: A method and a device for optically determining state variables inside a container (1) for liquefied gases. In the method and device, light emitted by an illumination unit (2) travels within an optical waveguide (7, 9) to a contact point (33) with the content of the container (1) and is partially reflected there, the intensity of the reflected light is measured by an image sensor (4), and a state variable is determined from the intensity. In order to create a comprehensive “image” of the state variables in the container and of the container content, several optical waveguides (29, 29?) are guided to contact points (33) which are distributed within the container (1) and form measurement points (9.1, 9.2, 9.3, . . . , 9.n). Locally assigned state variables (refractive index, density, temperature, etc.) of the container content are determined from the measured values obtained at the measurement points (9.1, 9.2, 9.3, . . . , 9.n) and are evaluated along with the spatial coordinates of the measurement points (9.

Abstract: A filling level detector for cryogenic liquids which are located in a container (1) uses a probe with a superconductor. In order to provide a filling level detector which is insensitive and costs little, the probe (11) is a flat conductor (20) which comprises a plurality of conductors which are routed parallel in a plastic matrix (21), of which a first conductor (23) is a super conductor, second conductors (24) are used to supply heating current to the first conductor (23), and third conductors (25; 25, 26) are used for voltage measurement, with the conductors in one pair (24, 25, 26) each being connected to points (27, 28 and 29, 30) which are at a distance from one another in the longitudinal direction of the probe. The probe is guided in a guide in the container.

Abstract: The present invention relates to a method for the calibration of a position determination system of a rear axle steering actuator for a motor vehicle. The rear axle steering actuator has an actuator element which can be driven by a rotary movement of a rotor to a translation movement and whose geometrical center position is determined by a reference measurement. The position determination system includes a linear sensor and a rotary sensor. During calibration, a piece of calibration information is generated which includes a piece of zero point information of the linear sensor and a piece of sector information. The measurement range of the rotary sensor is divided into at least two sectors. The sector information identifies that angle at which the angular position of the rotor lies when the actuator element is arranged in its geometrical center position. The calibration information is stored in the linear sensor.
