Patent number: 8917875Abstract: A circuit for operating loudspeakers includes a first, second, third and fourth loudspeaker circuit, having one input each for injecting a signal and one output each for connecting a loudspeaker input. The loudspeaker circuits are designed to amplify the injected signal and to provide the amplified signal at the outputs thereof. The loudspeaker circuits can, for example, be used for a 2.1 sound system. The three channels for a 2.1 sound system can be implemented by an amplifier circuit with four loudspeaker circuits, one loudspeaker circuit each being required for the two stereo channels left and right. A subwoofer channel can be driven differentially by two loudspeaker circuits. The stereo channels are, by contrast, only still connected to one loudspeaker circuit each, and so the stereo channels require at least one further common ground cable.Type: GrantFiled: September 29, 2011Date of Patent: December 23, 2014Assignee: Infineon Technologies AGInventors: Christoph Braun, Thomas Duda, Torsten Hinz

The closure device can be inserted into the core opening axially in relation to the core opening and provides at least one surface region which, in axial projection in relation to the core opening, can be made to abut a surface region of the casting that is facing toward the casting. The surface region lies radially outside a cross-sectional area predetermined by the core opening.Type: GrantFiled: September 9, 2010Date of Patent: May 13, 2014Assignee: Alstom Technology Ltd.Inventors: Martin Balliel, Christoph Didion, Thomas Duda, Marcel Koenig

Publication number: 20110171039Abstract: A blade arrangement of a gas turbine, with at least one blade which in the radial direction projects into a hot gas passage arranged concentrically to an axis, and terminates in a blade tip which with a clearance lies opposite a heat shield which delimits the hot gas passage. The blade and the heat shield are movable in relation to each other in the circumferential direction, and the blade tip and the heat shield are covered with coatings, which enable a directed cutting of the blade tip into the heat shield. By such a blade arrangement, a reduction of the clearance as a result of cutting in is simply achieved by the heat shield having a porous thermal barrier coating as an outer, abradable coating, and by the blade tip being provided with a homogenous, metallic cover coating.Type: ApplicationFiled: February 10, 2011Publication date: July 14, 2011Applicant: ALSTOM TECHNOLOGY LTDInventors: Thomas HEINZ-SCHWARZMAIER, Thomas DUDA, Alexander SCHNELL

Patent number: 7642821Abstract: A method for synchronizing a clock signal with a reference signal is disclosed. One embodiment has a first synchronization part which has a bit pattern having a particular clock period, a pause whose length is a multiple of this clock period plus a fraction of the clock period, and a second synchronization part having the particular clock period. The method includes generating a phase difference signal which is proportional to a phase difference between the clock signal and the reference signal, filtering the phase difference signal and providing a filtered phase difference signal, driving a digital oscillator in such a manner that the frequency of the clock signal is changed on the basis of the filtered phase difference signal, the phase of the clock signal within a clock period being corrected by a value corresponding to the fraction of the clock period at an end of the pause in the reference signal.Type: GrantFiled: February 15, 2007Date of Patent: January 5, 2010Assignee: Infineon Technologies AGInventors: Guenter Krasser, Thomas Duda

Patent number: 7544520Abstract: A method for applying a heat insulation layer (11, 12, 13) or a metallic protective layer to a thermally stressed component (200) having a basic material (10) in order to eliminate local damage (14) or an untreated place in the coating, includes, in a first step, pretreating the local damage (14) or untreated place, and, in a second step, applying layers (17, 18) necessary for eliminating the local damage (14) or untreated place. A markedly improved lifetime of the processed component can be achieved in that, within the first step, the edge regions (15) of the layers (11, 12, 13) ending at the local damage (14) or untreated place are processed so that they form uniformly sloped and terrace-shaped edge regions (16). Furthermore, a precharacterization of the entire coated region of the operationally stressed component or critical places by FSECT makes it possible to reduce the risk in terms of otherwise overlooked layer regions, the remaining lifetime of which would not persist for the following operating time.Type: GrantFiled: October 27, 2006Date of Patent: June 9, 2009Assignee: ALSTOM Technology Ltd.Inventors: Thomas Duda, Stefan Kiliani, Alexander Stankowski, Frigyes Szücs

Patent number: 7474876Abstract: A device for the production of standard compliant signals, for example pulse-type signals in a telecommunication network, serves the production and adaptation and/or pre-distortion of signals with a certain signal form, which is defined dependent on a standard signal form specified in a standard. The device comprises signal generation means (10) for the production of the signals with a certain signal form and signal adjustment means (20) for the adaptation or pre-distortion of the signals. The signal generation means (10) according to the invention are digitally realized, by using a programmable shift register (14), which contains multipliers specified by the standard signal form for multiplication with a digital input signal (1). The signal adjustment means (20) comprise substantially scalable digital filter arrangements in the form of a serial connection of digital filters (22) with a downstream multiplexer (24).Type: GrantFiled: August 12, 2004Date of Patent: January 6, 2009Assignee: Infineon Technologies AGInventors: Jörg Bonhaus, Thomas Duda, Lajos Gazsi, Peter Gregorius

The method includes the step of predamaging the protective coating before removing the protective coating from the substrate using dry ice blasting. The predamaging is performed so as to lead to an increase of efficiency of the removal process.Type: ApplicationFiled: January 23, 2008Publication date: July 31, 2008Applicant: ALSTOM Technology Ltd.Inventors: Thomas Duda, Lars Engl

Patent number: 7349508Abstract: A method and a device for reconstructing data, clocked at a symbol rate, from a signal which has been distorted by transmission of a transmission link, are disclosed. The method or respectively, the device, being predominantly performed or implemented, respectively, by means of digital circuit technology in order to improve the quality of the data recovery. The method includes amplifying the signal amplitude attenuated by the transmission; filtering high-frequency interference frequencies above the symbol rate; discretizing the analog signal by means of an analog/digital converter; performing a cable approximation by means of a digitally implemented cable approximation filter in order to obtain an equalized signal; and recovering the data from the equalized signal by means of a phase-locked loop.Type: GrantFiled: November 14, 2003Date of Patent: March 25, 2008Assignee: Infineon Technologies AGInventors: Thomas Duda, Lajos Gaszi, Peter Gregorius, Torsten Hinz, Martin Renner
