Patent number: 11662194Abstract: A method for determining measurement points of an adapted measurement path for measuring a measurement object includes determining measurement points of an ideal measurement path. The method includes determining target measurement points of at least one guide path, which differs from the ideal measurement path. The method includes capturing actual measurement points along the at least one guide path using a coordinate measuring device. The method includes determining deviations between the target measurement points and the actual measurement points of the at least one guide path. The method includes determining the measurement points of the adapted measurement path by changing the measurement points of the ideal measurement path based on the deviations.Type: GrantFiled: April 21, 2021Date of Patent: May 30, 2023Assignee: Carl Zeiss Industrielle Messtechnik GmbHInventors: Günter Haas, Rolf Häring, Jürgen Keller, Christian-Alexander Wirnsberger

Publication number: 20200169158Abstract: The invention relates to a synchronously excited rotary machine with a superconductive rotor comprising a plurality of projecting first pole units of a magnetic material and a plurality of second pole units having superconductive coils wrapped around a core element of a magnetic material. Each second pole unit is positioned between two adjacent first pole units. The second pole units are spaced apart from aback iron and the first pole units via a plurality of thermally insulating support elements, wherein this spacing is evacuated so that it acts as magnetic air gap. An enclosed housing is provided on the back iron in which the first and second pole units are arranged, where-in the superconductive coils of the second pole units are in fluid communication with a cooling system. The first pole units and back iron are operated at an ambient temperature while the second pole units are operated at a cryogenic operating temperature.Type: ApplicationFiled: December 1, 2016Publication date: May 28, 2020Inventors: Carsten Bührer, Jürgen Kellers, Jan Wiezoreck

Patent number: 8990089Abstract: A speech output is generated from a text input written in a first language and containing inclusions in a second language. Words in the native language are pronounced with a native pronunciation and words in the foreign language are pronounced with a proficient foreign pronunciation. Language dependent phoneme symbols generated for words of the second language are replaced with language dependent phoneme symbols of the first language, where said replacing includes the steps of assigning to each language dependent phoneme symbol of the second language a language independent target phoneme symbol, mapping to each one language independent target phoneme symbol a language independent substitute phoneme symbol assignable to a language dependent substitute phoneme symbol of the first language, substituting the language dependent phoneme symbols of the second language by the language dependent substitute phoneme symbols of the first language.Type: GrantFiled: November 19, 2012Date of Patent: March 24, 2015Assignee: Nuance Communications, Inc.Inventors: Johan Wouters, Christof Traber, David Hagstrand, Alexis Wilpert, Jürgen Keller, Igor Nozhov

Patent number: 7979280Abstract: An input linguistic description is converted into a speech waveform by deriving at least one target unit sequence corresponding to the linguistic description, selecting from a waveform unit database for the target unit sequences a plurality of alternative unit sequences approximating the target unit sequences, concatenating the alternative unit sequences to alternative speech waveforms and presenting the alternative speech waveforms to an operating person and enabling the choice of one of the presented alternative speech waveforms. There are no iterative cycles of manual modification and automatic selection, which enables a fast way of working. The operator does not need knowledge of units, targets, and costs, but chooses from a set of given alternatives. The fine-tuning of TTS prompts therefore becomes accessible to non-experts.Type: GrantFiled: February 22, 2007Date of Patent: July 12, 2011Assignee: Svox AGInventors: Johan Wouters, Christof Traber, Marcel Riedi, Martin Reber, Jürgen Keller

Patent number: 7531750Abstract: A power supply line for connecting a superconducting consumer system to a current delivery point, which is at a higher temperature than the consumer system, includes a carrier and a plurality of band-shaped, mechanically and electrically parallel high-temperature superconductors (HTSL). To achieve a high critical current density with simultaneously low heat-conducting capacity of the power supply line, the carrier includes at least one elongated plate that includes a sparingly (low) heat-conducting material, with a ratio of width to thickness of at least 3:1 and band-shaped HTSL that are arranged parallel adjacent to one another on the carrier. Each band-shaped HTSL also has a normally conducting current path.Type: GrantFiled: December 5, 2006Date of Patent: May 12, 2009Assignee: Zenergy Power GmbHInventors: Jürgen Kellers, Thomas Braun, Jan Wiezoreck

Patent number: 5725793Abstract: The present invention proposes adding an alkaline solution or a mixture of two or more alkaline solutions to the agent system of absorption machines operating with ammonia or methylamine as the agent and water as the solvent. This addition of an alkaline solution or an alkaline solution mixture has a number of advantageous effects. These are, i.a.1. The dissolving respectively expelling heat of the agent is reduced, raising the output figure.2. The agent vapor generated is very pure. A dephlegmator is obviated.3. The alkaline solution makes steel surfaces inert when sealed from air and in a high vaccum, thereby obviating corrosion inhibitors.4. The viscosity of the solvent is reduced, decreasing pump operation.Type: GrantFiled: June 15, 1995Date of Patent: March 10, 1998Assignee: Universitat SieganInventors: Jurgen Keller, Ralf Peters

Patent number: 4333894Abstract: A mass-transfer column consisting of one or more contact zones. The contact zones are exclusively provided with packings placed in prearranged locations. In the contact zones, optimal operating conditions for the packings are created over the entire height of the contact zones in order to achieve a minimal pressure loss at a concomitant high separating efficiency. This is done by implementing a suitable gradated adaptability of the packing to the vapor and liquid loads varying over the height of the contact zones.Type: GrantFiled: January 10, 1980Date of Patent: June 8, 1982Assignee: Veb Chemieanlagenbaukombinat Leipzig-GrimmaInventors: Klaus Hoppe, Jurgen Muller, Jurgen Keller, Bernd Kulbe, Klaus Lessig, Christian Berlin, Eckhard Danke
