Publication number: 20240100588Abstract: The invention relates to a method and to a device for generating three-dimensional objects by means of a generative method. According to the invention, powdered material and binding agents are applied sequentially and electromagnetic waves are used to cure the binding agent so that the powdered material bonded with the binding agent forms the three-dimensional object. The electromagnetic waves used are RF radiation. As a result, a fast and uniform curing of the three-dimensional object is achieved.Type: ApplicationFiled: October 9, 2020Publication date: March 28, 2024Inventors: Uwe Rothaug, Victor Romanov

Patent number: 7893705Abstract: A module for a tester for the testing of circuit boards is described. Such testers have a basic grid on which an adapter and/or a translator may be arranged in order to connect contact points of the basic grid with circuit board test points of a circuit board to be tested. The module comprises a support plate and a contact board. The contact board is formed by a rigid circuit board section which is described as the basic grid element, and at least one flexible circuit board section. Provided on the basic grid element are contact points which each form part of the contact points of the basic grid. The basic grid element is mounted at an end face of the support plate, and the flexible circuit board section is bent in such a way that at least part of the other section of the contact board is parallel to the support plate.Type: GrantFiled: June 15, 2009Date of Patent: February 22, 2011Assignee: atg Luther & Maelzer GmbHInventors: Andreas Guelzow, Victor Romanov, Volker Goldschmitt, Werner Mueller, Ruediger Dehmel, Uwe Rothaug

Patent number: 7821278Abstract: The invention relates to a method and a device for the testing of noncomponented circuit boards. The method according to the invention is used to determine deviations of circuit board test points of a series of circuit boards from the CAD data relating to these circuit boards, by scanning the surface of the circuit board by an imaging method and subjecting this image to automatic image analysis so that it may be compared with the CAD data. The CAD data are then suitably corrected so that, with the aid of the corrected CAD data, the circuit board may be tested in a finger tester, with test fingers of the finger tester being controlled on the basis of the deviations found.Type: GrantFiled: January 26, 2007Date of Patent: October 26, 2010Assignee: atg Luther & Maelzer GmbHInventors: Victor Romanov, Uwe Rothaug

Patent number: 5977776Abstract: The invention relates to a circuit board testing method, wherein an array of several circuits of a circuit board are short-circuited and further circuits are short-circuit tested by applying a high test voltage relative to said array of circuits, as a result of which the number of tests, which are normally highly time-intensive due to the high voltages, is drastically reduced since the further circuits do not need to be tested discretely relative to each circuit of the circuit array.Type: GrantFiled: January 8, 1998Date of Patent: November 2, 1999Assignee: atg Test Systems GmbHInventors: Ralf Huth, Uwe Rothaug

Patent number: 5903160Abstract: A method of testing an electrical conductor assembly having a plurality of networks is divided into a first test routine and in further test routines. A conductor assembly is tested in each test routine. In a first test routine, a field test for detecting short-circuits between the individual networks and a resistance test for detecting open-circuits in said networks are implemented. From the data sets resulting from the field test, complex conductances are determined between at least one antenna employed in the field test and the tested networks, which are used as reference conductances for the further test routines. In the further test routines short-circuits between the networks and/or open-circuits in the networks are detected by sensing a complex actual conductance between each network and at least one antenna and by comparing the actual conductance to the reference conductance. In addition the invention relates to an apparatus for implementing the method.Type: GrantFiled: November 5, 1996Date of Patent: May 11, 1999Assignee: atg Test Systems GmbHInventors: Evgueni Ianenko, Peter Bieber, Uwe Rothaug
