An example computer-implemented method includes transmitting, using one or more transmitters onboard an aircraft, one or more radio signals. Reflected radio data corresponding to one or more radio signals reflected from a plurality of radio detection and ranging (“radar”) reflectors placed at a plurality of locations associated with an aerial facility can be received using one or more radio receivers onboard the aircraft. A location for the aircraft can be computed based on the radio data and the plurality of locations associated with the aerial facility at which the radar reflectors are placed. A maneuver action for the aircraft can be initiated at a particular landing pad of the aerial facility based on the location.Type: ApplicationFiled: October 31, 2023Publication date: May 2, 2024Inventors: Michael Burghardt, Karsten Mueller, Andreas Stelzer, Heinz Haderer, Simon Scott

Publication number: 20230327929Abstract: An electronic device may include wireless circuitry that conveys data with a base station according to a communication standard and that detects range to an external object using a first antenna that transmits a waveform compliant with the standard. The waveform may be a Sounding Reference Signal (SRS) waveform, a transmit data waveform, or another waveform. A second antenna may receive a reflected signal that includes the transmitted waveform. The communications circuitry may perform element-wise division on symbols of a selected subcarrier in the reflected signal using corresponding phases and magnitudes of a set of complex OFDM symbols used to generate the transmitted waveform. Peak detection may be performed to detect the range. Using standard-compliant transmit waveforms to also perform spatial ranging may allow the communications circuitry to avoid dedicated radar circuitry while also minimizing impact to the transfer of the data.Type: ApplicationFiled: February 9, 2023Publication date: October 12, 2023Inventors: Jochen Schrattenecker, Michael Hofstadler, Andreas Springer, Reinhard Feger, Andreas Stelzer, Harald Pretl, Bernhard Sogl, Andreas Menkhoff

Patent number: 9327362Abstract: A method for positioning a welding head or welding torch of a robot welding system over a workpiece sends microwaves as a measuring signal from a transmitter arranged on the welding head to the workpiece. The microwaves reflected on the workpiece are received by at least one receiver arranged on the welding head, and the received microwaves are evaluated by an evaluation module for determining the position of a workpiece edge. The microwaves are sent from at least one transmitter in different positions on the welding head, and the reflected microwaves are received, with a change of polarization, by the at least one receiver, having a polarization plane arranged at an angle to the polarization plane of the transmitter. The position of the edge is determined by the evaluation module at least on the basis of a phase change of the respective microwaves reflected on the different positions.Type: GrantFiled: May 11, 2012Date of Patent: May 3, 2016Assignee: Fronius International GmbHInventors: Andreas Haderer, Andreas Stelzer

Publication number: 20110057762Abstract: A short-circuit device for the electrical bypass of an electric module has a contact arrangement, which is disposed in a switching chamber. The contact arrangement has an open circuit-breaker setting, in which a current flow via the contact arrangement is interrupted, and a contact setting, in which a current flow via the contact arrangement is made possible. A pyrotechnic drive for transferring the contact arrangement from its circuit breaker setting into its contact setting, enables cost-effective, rapid bypass or short-circuiting, and the provision of a large current carrying capacity simultaneously. The switching chamber is a vacuum switching chamber in which a vacuum prevails.Type: ApplicationFiled: January 6, 2009Publication date: March 10, 2011Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Jens Burger, Jörg Dorn, Thomas Kübel, Roman Renz, Andreas Stelzer, Andreas Zenkner

Patent number: 7709998Abstract: A plurality of exchangeable, different piezoelectric pressure sensors (4) comprise integrated SAW elements (60) as identification units whose identification data can be read by an interrogation unit (3) via a common connection cable (61). The analysis unit (2) for the measurement signals and the interrogation unit (3) for the identification data can be connected by a common coupling unit (5) to the connection cable (61). The coupling unit (5) has a coupling capacity (6) which connects with high frequency the interrogation unit (3) to the signal line of the connection cable (61), as well as a coupling inductance (7) which connects with low frequency the load amplifier (1) of the analysis unit (2) to the connection cable (61), thus neatly separating the useful signal from the identification signal and keeping a high-impedance measurement chain from the sensor (4) to the input of the load amplifier (1). An SFSCW radar can further be used to improve interrogation of the identification data.Type: GrantFiled: April 20, 2006Date of Patent: May 4, 2010Assignee: AVL List GmbHInventors: Andreas Stelzer, Robert Hauser, Stefan Schuster, Stefan Scheiblhofer, Klaus Leitmeier
