  • Publication number: 20240327309
    Abstract: Disclosed is a method for producing coated substrates, wherein a first aqueous suspension and a second aqueous suspension are produced, a layer of the first aqueous suspension is applied onto a substrate, a layer of the second aqueous suspension is applied onto the layer of the first aqueous suspension applied onto the substrate, and the resulting substrate coated is sintered. The first and second aqueous suspensions each contains a refractory metal carbide, a sinter additive and water. Additionally, the second aqueous suspension can contain a sinter additive, wherein the content by weight percentage of the sinter additive in the second aqueous suspension, based on the total weight of the second aqueous suspension, is less than the content by weight percentage of the sinter additive in the first aqueous suspension, based on the total weight of the first aqueous suspension. Also disclosed are a coated substrate produced using the method and the use of the coated substrate.

  • Patent number: 9165437
    Abstract: A method (100) is proposed for recognizing attempts at manipulating a self-service terminal, specifically a cash dispenser, in which a control panel with elements arranged therein, such as a keypad, cash-dispensing slot, etc. is provided, wherein a camera is directed onto at least one of the elements and wherein the image data generated by the camera are evaluated. Using edge detection, at least one edge image is created from the image data generated (step sequence 120). The edge image is evaluated using a reference edge image (step sequence 130). To generate the reference edge image, several individual images are used (step sequence 110). Fully automated evaluation and recognition of manipulation attempts is possible using edge detection.

  • Patent number: 7761995
    Abstract: A gear wheel includes multiple helical toothings, each having a different helical angle. A pressing method for molding a gear wheel involves introducing a compactable material into a chamber of a pressing tool, compacting the material, exposing the helical toothings of the gear wheel, and removing the molded body from the pressing tool. A pressing tool for pressing, as one part, a gear wheel, includes a matrix, cylindrical first and second molding tool parts which can be translated along and then rotated about a longitudinal axis, and a driver coupled to the molding tool parts or driving them. The molding tool parts can be moved towards and away from each other and the inner surface of the matrix delimits the chamber and is shaped to allow a linear axial sliding movement of the compactable material relative to the matrix.

  • Publication number: 20090169059
    Abstract: The invention relates to methods for determining a motion vector in a predetermined area of a sequence of digital images by comparing a current image to a preceding image. The current image and the preceding image are prepared by the same filter for image adaptation. Distance vectors between a pixel of a current image and balanced pixels of the preceding image in a predetermined environment are determined, said distance vectors being averaged in order to form a displacement vector for the pixel. The displacement vectors are averaged and the displacement vector is produced.
