Patent number: 10175316Abstract: Gradient coil arrangement for a magnetic resonance apparatus has multiple sub-coils formed by coil conductors on a common substrate, and the gradient coil arrangement has at least one damping producer that damps voltage overshoots occurring due to capacitive and/or inductive coupling between two sub-coils as a result of interfering frequencies in the wanted signal for at least one of the sub-coils affected. The damping producer is directly applied to the coil conductor of at least one of the sub-coils involved in the capacitive and/or inductive coupling.Type: GrantFiled: February 5, 2016Date of Patent: January 8, 2019Assignee: Siemans AktiengesellschaftInventors: Sascha Fath, Marcel Rischke, Markus Vester

Publication number: 20120128872Abstract: A ceramic layer is fabricated on a substrate by coating the substrate with a material containing chemical precursors of a ceramic. The precursors are transformed by a heat treatment into the ceramic to be fabricated. Different methods for heat insertion may be used for individual layers by absorbing particles, which are utilized in different concentrations or different chemical compositions. A targeted heat insertion even in lower layer regions, for example, by microwave animation, or ultraviolet or infrared light insertion is therefore possible. Beneficially, as a result, comparatively thick layers in particular can be fabricated by a single heat treatment layer.Type: ApplicationFiled: May 12, 2010Publication date: May 24, 2012Applicant: Siemans AktiengesellschaftInventors: Christian Doye, Jens Dahl Jensen, Ursus Krüger, Kathrin Kunert, Raymond Ullrich, Gabriele Winkler

Publication number: 20080126081Abstract: A method for the artificial extension of the bandwidth of speech signals involves: a) Provision of a wideband input speech signal (swbi(k)); b) Determination of the signal components (seb(k)) of the wideband input speech signal (swbi(k)) required for the bandwidth extension from an extension band from the wideband input speech signal (swbi(k)); c) Determination of the temporal envelopes of the signal components (seb(k)) determined for the bandwidth extension; d) Determination of the spectral envelopes of the signal components (seb(k)) determined for bandwidth extension; e) Encoding of the information for the temporal envelopes and the spectral envelopes, and provision of the encoded information by carrying out the extension of the bandwidth; f) Decoding of the encoded information and generation of the temporal envelopes and the spectral envelopes from the encoded information for the production of a bandwidth-extended output speech signal (swbo(k)).Type: ApplicationFiled: June 30, 2006Publication date: May 29, 2008Applicant: SIEMANS AKTIENGESELLSCHAFTInventors: Bernd Geiser, Peter Jax, Stefan Schandl, Herve Taddei, Aulis Telle, Peter Vary

Patent number: 6361509Abstract: A therapy apparatus has a source with an acoustic axis for generating acoustic waves converging in a focus lying on the acoustic axis. The source has a light generator that emits a focused light beam of visible light with a substantially parallel beam path that substantially coincides with the acoustic axis of the source and makes it visible.Type: GrantFiled: December 17, 1999Date of Patent: March 26, 2002Assignee: Siemans AktiengesellschaftInventor: Thomas Reuner

Patent number: 5824122Abstract: In a process and an apparatus for purifying flammable gas, in particular low-temperature carbonization gas, the gas is scrubbed and discharged as pure gas and condensate. The condensate is distilled in a distillation unit. Volatile constituents are admixed to the pure gas, so that the calorific value of the latter is increased. The non-volatile constituents are discharged. The non-volatile constituents can be fed to a low-temperature carbonization drum and carbonized therein at low temperature.Type: GrantFiled: May 27, 1997Date of Patent: October 20, 1998Assignee: Siemans AktiengesellschaftInventors: Gerd Baumgartel, Herbert Tratz

Patent number: 5654634Abstract: A method for detecting gaps to be bridged in a power supply of an electric rail vehicle includes continuously sensing at least one conductor rail for gaps with at least one contact signal transmitter travelling ahead of a plurality of electrically interconnected real current collectors, as seen in the direction of travel of the rail vehicle, with signal information obtained being stored. An instantaneous contact situation between the real current collectors and the conductor rail is determined from the memory contents. Positions of a virtual current collector travelling in advance are formed for each real current collector from the memory contents, with the distances between the contact signal transmitter and the virtual current collectors being such that a necessity to change over the traction power converter into the regenerative braking mode is indicated as soon as all of the virtual current collectors meet a gap in the conductor rail.Type: GrantFiled: October 30, 1995Date of Patent: August 5, 1997Assignee: Siemans AktiengesellschaftInventor: Erich Minderlein
