Patent number: 11909519Abstract: Embodiments provide transfer methods. The method includes a step of transferring data of a first class from a data transmitter to a data receiver, wherein the data of the first class is transferred divided onto a first plurality of sub-data packets using a first hopping pattern. Furthermore, the method includes a step of transferring data of a second class from the data transmitter or a different data transmitter to the data receiver, wherein the data of the second class is transferred divided onto a second plurality of sub-data packets using a second hopping pattern, wherein transmission pauses between sub-data packets transferred according to the first hopping pattern are smaller than transmission pauses between sub-data packets transferred according to the second hopping pattern.Type: GrantFiled: May 6, 2020Date of Patent: February 20, 2024Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Gerd Kilian, Josef Bernhard, Guenter Rohmer, Maximilian Roth, Frank Nachtrab, Jakob Kneissl, Johannes Wechsler, Michael Schlicht, Raimund Meyer, Frank Obernosterer

Patent number: 9638805Abstract: Embodiments provide a satellite navigation receiver. The satellite navigation receiver has a receiver unit and a transmitter or a controller. The receiver unit is configured to receive and process a satellite navigation signal from a satellite navigation system at the certain time, to obtain a received signal, the received signal having a first component in a digital form, wherein the first component in the digital form is encrypted. The transmitter is configured to transmit the first component in the digital form together with an identification of a user of the satellite navigation receiver at the certain time. The controller is configured to store the first component in the digital form on a non-volatile storage medium in association with other data representing an information from a location, at which the satellite navigation receiver was located at the certain time.Type: GrantFiled: July 5, 2013Date of Patent: May 2, 2017Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FOERDERUNG DER ANGEWANDTEN FORSCHUNG E.VInventors: Alexander Ruegamer, Manuel Stahl, Guenter Rohmer

Patent number: 8503958Abstract: A signal processor for processing a receiving signal having a first usable frequency band and a second usable frequency band includes a first mixer for mixing the receiving signal with a first local oscillator signal, wherein a frequency of the first local oscillator signal is asymmetrical between the first usable frequency band and the second usable frequency band. The first mixer is implemented to obtain an in-phase signal and a quadrature signal, having a first signal portion representing a mixed image of the first usable frequency band, and having a second signal portion representing a mixed image of the second usable frequency band. The signal processor comprises a second mixer) for mixing the in-phase signal and the quadrature signal by using the second local oscillator signal.Type: GrantFiled: June 20, 2007Date of Patent: August 6, 2013Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Alfonso Carrera, Stefan Koehler, Guenter Rohmer

Publication number: 20110234313Abstract: An amplifier for an input signal Sin, present at an input terminal, with a gain factor adjustable by a control terminal, so as to provide the amplified input signal Sin? at an output terminal. A decoupler is connected to the amplifier on the output side and provides a decoupling signal Sactual which depends on the amplified input signal Sin?. The decoupling signal Sactual is processed in an analog manner, and a prepared signal Sactual? is provided which is a measure of the actual output power. Comparing the prepared signal Sactual? to a target value Starget in an analog manner yields a comparison signal Scontrol controlling the gain factor, and a target value Starget is a measure of the target power of the amplified input signal Sin?. The processor is implemented to create a predetermined ratio between the target power and the actual power.Type: ApplicationFiled: March 23, 2007Publication date: September 29, 2011Inventors: Peter Spies, Guenter Rohmer, Heinz Gerhaeuser
