Patent number: 10183592Abstract: An exhaust-air guide of a fuel cell stack having a cooling structure, in particular in a motor vehicle, is provided. The cooler structure belongs to the functional environment of the fuel cell stack and is in form through which ambient air flows. The exhaust air of the fuel cell stack is guided to a point upstream of the cooler structure such that the exhaust air flows through the cooler structure in a throughflow direction and, in so doing, entrains ambient air in accordance with the jet pump principle. The exhaust air of the fuel cell stack may be cooled before being guided to the cooler structure. The exhaust air of the fuel cell stack is guided to a point upstream of the cooler structure in multiple pipes that are oriented at least approximately parallel to the inflow surface of the cooler structure, from which pipes the exhaust air emerges via outlet openings in the pipe wall. The outlet openings are situated at a suitable angle with respect to the throughflow direction.Type: GrantFiled: December 31, 2014Date of Patent: January 22, 2019Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Stefan Haase, Andreas Buchner, Michael Bauer

Patent number: 9688160Abstract: A method of operating an electric system of a motor vehicle, consisting of a fuel cell system, an accumulator and an electric driving motor is provided. Without implementing an electric voltage conversion and therefore without an electric voltage converter, as a function of the level of the electric voltage made available by the fuel cell system and by the accumulator and the electric power demanded by the electric motor, a first switching element in the connection between the fuel cell system and a node point electrically connected with the accumulator and the electric motor, as well as a second switching element in the connection between the accumulator and this node point are opened or closed as needed. This is done such that the power requirement of the electric motor is met primarily from the fuel cell system, and in an auxiliary fashion, additionally from the accumulator.Type: GrantFiled: March 25, 2014Date of Patent: June 27, 2017Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Georg Goetz, Sylvester Burckhardt, Michael Bauer, Andreas Buchner, Florian Pfattrisch

Patent number: 9604654Abstract: The invention relates to an arrangement for supplying a rail vehicle with electrical energy. One electrical machine is allocated to each of at least two internal combustion engines for generating electrical energy. A common controller is designed to start the internal combustion engines individually as required. At least one pre-heating device is designed to pre-heat the internal combustion engines before a start. A temperature detection device is thermally coupled to the internal combustion engines. The controller is designed, during an operation of one of the internal combustion engines, to start another of the internal combustion engines if, due to cooling of the other internal combustion engine, a temperature of the other internal combustion engine detected by a temperature identifying device reaches or exceeds a temperature threshold.Type: GrantFiled: April 15, 2014Date of Patent: March 28, 2017Assignee: Bombardier Transportation GmbHInventors: Werner Sonnleitner, Andreas Buchner, Michael Kretz

Patent number: 9579499Abstract: Methods, systems, and devices for determining a stimulus based on a masking model of human hearing are disclosed. An example method includes receiving a signal that includes information indicative of one or more spectral components of a sound. The example method also includes determining a masking curve that includes information indicative of one or more masking spectral components. The masking curve is determined according to a masking model of human hearing that accounts for at least an effect due to temporal masking. The example method further includes generating a stimulus based on a difference between the one or more spectral components and the one or more masking spectral components. The stimulation allows a recipient to perceive at least a portion of the sound.Type: GrantFiled: November 5, 2012Date of Patent: February 28, 2017Assignee: Cochlear LimitedInventors: Eugen Kludt, Andreas Büchner
