Abstract: The invention relates to a method for determining correction information for an electric machine (7) which has a stator winding and a rotatably mounted rotor having multiple pole pairs, wherein a reference rotational angle (?Ref) of the rotor is selected; an actual variable influenced by a rotation of the rotor is determined and is monitored for interference waves (SW); when an interference wave (SW) is detected, an interference-wave correction instruction which is based on the reference rotational angle (?Ref) and is intended for compensating for the detected interference wave (SW), and a reference feature of the interference wave (SW) based on the reference rotational angle (?Ref) are determined; a reference rotational angle value of the reference rotational angle (?Ref) is determined on the basis of a rotational angle interval (??el) covered during an electrical revolution of the rotor; and the determined interference-wave correction instruction, the determined reference feature and the determined referenc

Abstract: A method for providing mapping data for a map of a deployment environment for at least one mobile unit. The method includes reading in reference image data from an interface to an image acquisition apparatus of the mobile unit. The reference image data represent reference images, which are captured by way of the image acquisition apparatus from subportions specific to each reference image of the ground of the deployment environment, wherein adjacent subportions partially overlap. Reference image features are extracted for each reference image using the reference image data. Positions of the reference image features in each reference image are determined. Using the reference image data, a reference feature descriptor is ascertained at the position of each reference image feature in order to produce mapping data. The mapping data include the reference image data, the positions of the reference image features and the reference feature descriptors.

Abstract: An operating interface (10) is in an interior of a vehicle and has a surface (11) that is visible in the interior. The operating interface (10) has an operating element (14) that can be shifted relative to the surface (11) between resting and operating positions. The operating element (14) has a display (17) that is inactive in the resting position and does not indicate a functional assignment of the operating element (14). However, the display (17) is active in the operating position and indicates a functional assignment of the operating element (14). The operating element (14) has a first orientation to the surface body (11) when in the operating position and has a second orientation to the surface body (11) when in the resting position. A gap (19) is formed between the operating element (14) and the surface body (11) and surrounds the operating element (14).

Abstract: A propane gas-utilizing system includes a housing having propane gas and a propane leakage prevention material having a catalyst, scavenger, and/or oxidizer of the propane gas arranged in the housing and including at least one of (a) an oxide material having at least one composition of formula (I): Ru1-xMxO2 (I), where 0<x?0.1 and M is Ag, K, Pt, Rh, or Ir, or (b) an oxide material having at least one composition of formula (II): Co3-xMxO4 (II), where 0<x?0.3, and M is Pd, Cu, or Sr, or (c) an oxide material having at least one composition of formula (III): MM?xOy (III), where x is a stoichiometric ratio of M? to M, 0?x?1.5, y is a stoichiometric ratio of O to M, 1?y?3, M is an alkali metal, and M? (if x>0) is Y, Ce, Nb, Ta, La, Nd, Mn, Ag, Au, or Cr.

Abstract: The present invention relates to a sealing sleeve for the separated supply and discharge of a cooling medium that comprises a sealing member that is pivotally symmetrical about the longitudinal axis, a protrusion projecting radially outwardly with respect to the longitudinal axis at the upper longitudinal end of the sleeve member, a protrusion projecting radially outwardly with respect to the longitudinal axis at the lower longitudinal end of the sleeve member, a first web section and a second web section of which each one extends in the axial direction of the sleeve member and connects the upper protrusion to the lower protrusion, and a first wall region and a second wall region of which each one is bounded in the axial direction by the upper and lower protrusions and in the peripheral direction by the first and second web sections and is radially inward offset with respect to these elements, with the upper protrusion and the lower protrusion each extending continuously around the total periphery of the slee

Abstract: The invention relates to a method of manufacturing a textile or foil-based sheet body which has a multicompartment structure, wherein the textile or foil-based sheet body is an at least two-ply stitched woven fabric, an at least two-ply fused, welded or adhered foil, a combination thereof and/or a one-piece woven (OPW) fabric, comprising the steps of forming auxiliary channels (2) around the shape of the outer contour of the compartments; filling the auxiliary channels (2) with a mobile silicone-based sealant comprising an additive; and curing the sealant. The invention further relates to the multicompartment vessels obtained by the method of the invention.
