Publication number: 20240077985Abstract: An electronic device may include one or more sensors that capture sensor data for a physical environment around the electronic device. The sensor data may be used to determine a scene understanding data set for an extended reality environment including the electronic device. The scene understanding data set may include information such as spatial information, information regarding physical objects in the extended reality environment, and information regarding virtual objects in the extended reality environment. When providing scene understanding data to one or more applications running on the electronic device, spatial and/or temporal restrictions may be applied to the scene understanding data set. Scene understanding data that is associated with locations within a boundary and that is associated with times after a cutoff time may be provided to an application.Type: ApplicationFiled: June 21, 2023Publication date: March 7, 2024Inventors: Divya T.

Patent number: 9893520Abstract: A switching device for switching bipolar DC currents in a high-voltage system includes at least two electromechanical switching units and a semiconductor switching arrangement. The electromechanical switching units have a first switching status and a second switching status. In the first switching status, the DC current can be passed via at least one of the electromechanical switching units without in this case flowing via the semiconductor switching arrangement. In the second switching status of the electromechanical switching units, the DC current can be passed via the semiconductor switching arrangement and can be switched off.Type: GrantFiled: June 4, 2012Date of Patent: February 13, 2018Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Herbert Gambach, Gerd Griepentrog, Lutz-Ruediger Jaenicke, Reinhard Maier, Norbert Trapp

Patent number: 9240680Abstract: A switch for a high-voltage direct current transmission path includes a vacuum circuit breaker for disconnecting the transmission path and a gas-insulated circuit breaker for disconnecting the transmission path. The gas-insulated circuit breaker is connected in series with the vacuum circuit breaker. A device is provided for building up a counter-current against the current in the transmission path for the purpose of reducing the current across the vacuum circuit breaker. The elements of the switch are actuated by a control device in such a way that the switch is switched off at or close to the zero crossing of the current.Type: GrantFiled: March 5, 2012Date of Patent: January 19, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Werner Hartmann, Lutz-Ruediger Jaenicke, Sylvio Kosse, Reinhard Maier, Anthoula Panagou, Norbert Trapp

Patent number: 7916442Abstract: In breaker devices an early short-circuit recognition is required and also a tripping of the contacts. The recognition of a short-circuit occurs so early that with consideration of the response time of the measuring probes and the unlocking mechanism by a suitable analysis algorithm the release of the movable contact occurs before or at least at the time that the current-breaking forces correspond to the contact force. The contact force is hence compensated for and a rapid opening of the contacts can be achieved.Type: GrantFiled: July 26, 2005Date of Patent: March 29, 2011Assignee: Siemens AktiengesellschaftInventors: Michael Anheuser, Gerd Griepentrog, Reinhard Maier, Bernd Trautmann

Patent number: 7242177Abstract: A method with corresponding circuit arrangement is disclosed, whereby for evaluation of a measured signal arising as an analogue value with a potential greater than zero potential in a measuring device requiring a supply current, the measured information therefrom is transmitted as a digital signal to an analytical unit lying at earth potential after an A/D conversion. The generated digital signal thus provides the clock signal for a modulation of the supply current and thus also carries out the function of the carrier for the information content of the measured signal. Curved characteristic lines for compression/decompression of the signals are used. Suitable devices for temperature compensation may be similarly provided.Type: GrantFiled: August 7, 2003Date of Patent: July 10, 2007Assignee: Siemens AktiengesellschaftInventors: Reinhard Maier, Jürgen Rupp
