Patent number: 7225376Abstract: A method and system for efficiently coding test pattern for ICs in scan design and build-in linear feedback shift register (LFSR) for pseudo-random pattern generation. In an initialization procedure, a novel LFSR logic model is generated and integrated into the system for test data generation and test vector compression. In a test data generation procedure, test vectors are specified and compressed using the LFSR logic model. Every single one of the test vectors is compressed independently from the others. The result, however, may be presented all at once and subsequently provided to the user or another system for further processing or implementing in an integrated circuit to be tested. According to the present invention a test vector containing 0/1-values for, e.g., up to 500.000 shift registers and having, e.g., about 50 so called care-bits can be compressed to a compact pattern code of the number of care-bits, i.e., 50 bits for the example of 50 care-bits.Type: GrantFiled: July 30, 2003Date of Patent: May 29, 2007Assignee: International Business Machines CorporationInventors: Joerg Georg Appinger, Michael Juergen Kessler, Manfred Schmidt

Patent number: 6983407Abstract: A plurality of pseudo random bit-pattern generators (PRPGs), advantageously linear feedback shift registers (LFSRs), having predetermined lengths and individual different tap locations for providing a respective sequence of pseudorandom bit-patterns. An output from a predetermined respective tap location at each LFSR is fed to a common OR-gate, a selected subset of the LFSRs are initialized with all bit storing locations to “0” in order to generate a respective permanent “0”-bit sequence, and the output of the OR-gate is used for reading the weighted or flat random bit output-pattern thereof. By controlling the number of zero-set LFSRs—a subset of the LFSRs—the weight of the generated output-pattern can be controlled.Type: GrantFiled: June 11, 2003Date of Patent: January 3, 2006Assignee: International Business Machines CorporationInventors: Joerg Georg Appinger, Michael Juergen Kessler, Manfred Schmidt

Patent number: 5493162Abstract: A pole core with pole lips serves for fixing a field winding in the pole housing of a direct current motor. The pole core has a central pole body mountable on an inner side of the pole housing. The pole lips are formed of one piece with the central pole body and are resiliently and springily connected to the central pole body, so that the field coil can be pressed against the pole housing in an elastic springy manner without additional spring elements, so that no damage occurs to the insulating coat of the coil.Type: GrantFiled: March 18, 1993Date of Patent: February 20, 1996Assignee: Robert Bosch GmbHInventors: Hans Wuerth, Werner Pfander, Walter Gritschmeier, Wilhelm Post, Juergen Leinhos, Hans-Juergen Kessler, Klaus Eilert, Dittmar Kleemann, Uwe Kroeger, Juergen Seeliger, Juergen Soellick, Gerda Wurth nee Eurich

Patent number: 4449877Abstract: The disclosure relates to a one-piece masonry dowel, pin or peg (10) for fitted implantation in a bore having an internal enlargement (24), a tool (31) for and method of making the enlargement (24), and a tool for implanting the peg in the bore. The peg (10') consists of a sleeve (11) with internal threading (21) for a fastening screw, the leading part (14) of this sleeve having a plurality of thickened segments of a cylinder separated by axial slots, and the outer diameter of the cylinder made up of these segments being variable in such a way that the sleeve can be pushed into a bore and snapped into an enlargement in this bore. The leading part (14) of the sleeve (11) is integrally provided at the end thereof which leads in the push-in direction with an extension (19) which is likewise divided longitudinally into segments and the outer diameter of which in its relaxed condition corresponds to that of the unslotted annular part (12) of the sleeve (11).Type: GrantFiled: April 21, 1980Date of Patent: May 22, 1984Assignee: Hilti AktiengesellschaftInventor: Juergen Kessler

Patent number: 4444279Abstract: A drilling tool adapted to produce a radial enlargement along a cylindrical elementary drilled hole in concrete masonry. The tool comprises at least one cutter which is mounted in a slot in a drill sleeve which enters the elementary drilled hole, this cutter being held so as to be fixed in the peripheral direction and axially but movable radially by an inner spreader element, provided with chamfered surfaces, which is movable axially relatively to the drill sleeve. This spreader element is in one piece with the shank, which is directly rotatively driven, is movable axially relatively to the drill sleeve and is close-fitted therewith in the peripheral direction. The end of the drill sleeve projecting out of the elementary drilled hole is connected to an abutment piece which determines the location of the radial enlargement along the drilled hole.Type: GrantFiled: June 30, 1980Date of Patent: April 24, 1984Assignee: Hilti AktiengesellschaftInventors: Juergen Kessler, Harry Melzer
