Patent number: 11493457Abstract: A method for the X-ray inspection of products of a predefined product type including at least one first component and one second component having different absorption coefficients for X-radiation. X-radiation with a spectral range is transmitted through a product to be examined. The X-radiation that has passed through the product is detected by means of a spectrally resolving X-ray detector. The spectrally resolving X-ray detector assigns the X-ray quanta to a number of energy channels and generates image data which for each pixel include spectral values for selected or all energy channels and/or total spectral values for one or more groups of adjacent energy channels. At least one mapping rule is used to process the image data to form a total image, where each mapping rule is designed such that spectral values or total spectral values are mapped onto a total image value of an image point.Type: GrantFiled: April 27, 2020Date of Patent: November 8, 2022Assignee: Wipotec GmbHInventors: Christian Bur, Marco Wickert

Patent number: 11248907Abstract: A test block is formed of at least one profile block and one mating block, wherein the two blocks lying one on top of the other with varying thickness combinations are radiographed together, in order to ascertain, for the pairings of the materials in the respective thickness, in each case a reference value relating to their common radiographic properties.Type: GrantFiled: April 28, 2020Date of Patent: February 15, 2022Assignee: Wipotec GmbHInventors: Ulrich Heil, Christian Bur

Patent number: 11073486Abstract: An X-ray detector device for a device for the X-ray inspection of products includes a first line detector with a first discrete spatial resolution, a second line detector with the same or lesser second discrete spatial resolution, and an evaluation and control unit. The first line detector is operable to capture X-radiation in a non-spectrally resolved fashion along a first capture line transverse to a product movement direction to generate first image data. The second line detector is operable to capture the X-radiation in a spectrally resolved fashion along a second capture line parallel to the first capture line to generate second image data. The evaluation and control unit is operable to evaluate the first and second image data to detect at least one predefined feature of the product with the first discrete spatial resolution by combining the items of information contained in the first and second image data.Type: GrantFiled: April 27, 2020Date of Patent: July 27, 2021Assignee: Wipotec GmbHInventors: Michael Siegrist, Ulrich Heil, Christian Bur, Kai Hoffmann

Patent number: 10012262Abstract: A flexure hinge with two material segments connected to each other via a material tapering to a thin spot which defines a pivot axis between the two material segments. The material segments are provided with recesses such that the strength existing in the thin spot with respect to normal stresses or bending stresses is kept largely constant within a distance from the thin spot.Type: GrantFiled: May 31, 2017Date of Patent: July 3, 2018Assignee: Wipotec GmbHInventors: Andreas Rübel, Christian Bur
