Patent number: 11549802Abstract: The invention relates to a sensor device for examining the coating of a disc as part of a coating process. The sensor device comprises a first optical sensor system for determining the layer thickness of the coating applied to the disc, and comprises a rotation apparatus. The invention is characterized in that the first optical sensor system is designed to simultaneously identify at least one first position-based measured value and one second position-based measured value, the first and the second position-based measured value describing the distance between the sensor systems and the surface of the disc. As a result of this, the sensor system is configured such that the first position-based measured value of a coated region of the disc and the second position-based measured value of an uncoated region of the disc are identified. Furthermore, the first optical sensor system comprises at least one linear guide, which extends from the central region to the edge.Type: GrantFiled: August 25, 2020Date of Patent: January 10, 2023Assignee: STURM MASCHINEN- & ANLAGENBAU GMBHInventor: Wolfgang Ullrich

Patent number: 10612903Abstract: A test system for examining a hollow body, in particular a cylinder bore in an engine block, comprises a measuring apparatus comprising an elongate body and a plurality of sensors which are connected to the body and are set up to carry out a distance measurement. The test system also comprises electronic control means which are set up to move the measuring apparatus into a hollow body to be examined and to determine an internal diameter of the hollow body on the basis of distance measurement data from the sensors. In order to examine hollow bodies of different diameters, at least some of the sensors are in the form of movable sensors which can be moved relative to the elongate body of the measuring apparatus. The electronic control means are also set up to select a measuring position of the movable sensors relative to the elongate body on the basis of a hollow body to be examined.Type: GrantFiled: January 15, 2016Date of Patent: April 7, 2020Assignee: Sturm Maschinen- & Analagenbau GmbHInventors: Gerhard Aufschläger, Wolfgang Ullrich, Florian Bader, Marc Kesting, Ralf Völlinger
