Patent number: 12055072Abstract: A method for modifying an existing single shaft combined cycle power plant having a steam turbine part and a gas turbine part which are connected to each other rigidly by an intermediate shaft. The gas turbine part is supported by two pin-ended supports allowing a certain axial displacement of the casing by rotating about corresponding axes. The old gas turbine part is replaced by a new gas turbine part having a different structure, namely a rigid support and a flexible support. Relative thermal expansion or displacement of the intermediate shaft is compensated by a hydraulic unit comprising a double-acting piston for displacing the gas turbine rotor with respect to the gas turbine stator. The hydraulic unit is controlled based on a displacement measurement in the steam turbine.Type: GrantFiled: March 23, 2020Date of Patent: August 6, 2024Assignee: Siemens Energy Global GmbH & Co. KGInventors: Stefan Janssen, Michael Kursch, Till Spielmann, Johann Stach, Oliver Tobias Walk, Kai Wöstmann

Patent number: 10704097Abstract: The present invention relates to diagnosis and/or prognosis of cardiovascular disease and cardiovascular events. A prognostic risk score in relation to the cardiovascular events, more particular after intervention, can be determined by counting the number of deregulated genes (or derived proteins) in their isolated monocytes. Deregulation means low expression of COX1 and/or COX4I1, and/or TFAM, and/or RUNX2.Type: GrantFiled: August 26, 2016Date of Patent: July 7, 2020Assignee: KATHOLIEKE UNIVERSITEIT LEUVENInventors: Paul Holvoet, Stefan Janssens, Peter Sinnaeve

Patent number: 9494046Abstract: A method for operating a rotary machine with a rotor that is mounted in a bearing is provided. The rotor is subjected to a thrust that acts substantially in only an axial direction during the operating time. The thrust is received and dissipated by a first thrust bearing of the bearing via sliding means, the bearing having a second thrust bearing. The axial vibrations of the rotor are damped or completely prevented by means of the second thrust bearing generating a force that acts on the first thrust bearing in the direction of the thrust at least temporarily at the same time as the thrust occurs.Type: GrantFiled: July 23, 2012Date of Patent: November 15, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Stefan Janssen, Michael Kursch

Publication number: 20040127449Abstract: This invention relates to a gene therapy method for inducing pulmonary vasodilation. More specifically, this invention involves introducing the nitric oxide synthase gene into lungs resulting in pulmonary vasodilation. This results in a hypotensive effect in the pulmonary circulation which does not significantly affect systemic blood pressure or cardiac index. This method is useful to treat primary pulmonary hypertension or pulmonary hypertension secondary to various disease states.Type: ApplicationFiled: December 22, 2003Publication date: July 1, 2004Inventors: Stefan Janssens, Kenneth D.

Patent number: 6223274Abstract: A programmable processing engine and a method of operating the same is described, the processing engine including a customized processor, a flexible processor and a data store commonly sharable between the two processors. The customized processor normally executes a sequence of a plurality of pre-customized routines, usually for which it has been optimized. To provide some flexibility for design changes and optimizations, a controller for monitoring the customized processor during execution of routines is provided to select one of a set of pre-customized processing interruption points and for switching context from the customized processor to the flexible processor at the interruption point. The customized processor can then be switched off and the flexible processor carries out a modified routine. By using sharable a data store, the context switch can be chosen at a time when all relevant data is in the sharable data store. This means that the flexible processor can pick up the modified processing cleanly.Type: GrantFiled: November 19, 1998Date of Patent: April 24, 2001Assignee: Interuniversitair Micro-Elecktronica Centrum (IMEC)Inventors: Francky Catthoor, Miguel Miranda, Stefan Janssens, Hugo De Man

Patent number: 5978509Abstract: A battery-powered computing system (20) including video decoding capability, particularly as pertinent to the H.263 standard, is disclosed. The system (20) includes a main integrated circuit (30) having an on-chip central processing unit (CPU) (32) and on-chip shared memory (33) for the temporary buffering of video image data that is retrieved and generated during the video decoding process. The CPU (32) is programmed to perform a combined P and B prediction process (46) upon a previously predicted P frame (P.sub.T-1), with accesses to internal buffers in shared memory (33) instead of to main memory (40). Preferably, inverse transform processes (48, 52) also access shared memory (33) rather than main memory (40). The combined P and B prediction process (46) preferably handles unrestricted motion vectors using edge pixels (P.sub.Type: GrantFiled: October 22, 1997Date of Patent: November 2, 1999Assignees: Texas Instruments Incorporated, Inter-University Microelectronics Center (IMEC)Inventors: Lode J.M.
