Patent number: 11099266Abstract: Using a distance sensor, a set of distances to a target object is measured, a distance in the set being measured at a time. From the set of distances and corresponding times, a trajectory of the target object is predicted.

Responsive to the trajectory being predicted to intercept a defined volume around the distance sensor and responsive to the correlation being above a threshold degree of correlation, the target object is classified as a threat. Responsive to the trajectory being predicted to intercept a defined volume around the distance sensor and responsive to the correlation being below a threshold degree of correlation, a threat level corresponding to the target object is identified based on the trajectory of the target object and trajectory of the friendly device.Type: GrantFiled: January 11, 2019Date of Patent: August 24, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Yun Zhai, Peter Alan Coldicott

Patent number: 11099051Abstract: A method for determining the fill level of a medium involves continuous wave radar measurement and a corresponding fill level measuring device. A coded transmit signal is emitted by a transmitter, reflected at the medium, and received by a receiver as a reflection signal. The reflection signal and a signal derived from the transmit signal are subjected to a correlation analysis, and a correlation outcome results. A control and evaluation unit determines the time offset of the correlated signals with the correlation outcome, and uses it to determine the fill level of the medium. The reflection signal and the derived signal are mixed with the analog mixer into a mixer output signal that is sampled and quantized to a digital mixer output signal. The correlator has a digital integrator with which a sequence of digital mixer output signals is digitally integrated into the correlation outcome.Type: GrantFiled: October 5, 2018Date of Patent: August 24, 2021Assignee: KROHNE S.A.S.Inventors: Michael Vogt, Robert Storch, Gordon Notzon

Patent number: 11086004Abstract: Radar frequency range signals (e.g., 1 to 100 gigahertz) are often generated by upconverting a reference frequency to a transmission frequency, and a received signal may be downconverted to analyze information encoded on the transmission via modulation. Modulation may be achieved via a fractional frequency divider in a phase-locked loop, but fractional spurs may reduce the signal-to-noise ratio. Additionally, the ramp slope may vary due to phase-locked loop momentum. Instead, a clock generator may generate clock signals for a digital front end comprising a digital signal modulator that generates modulated digital values comprising quadrature representations of a radar modulation signal, which are encoded by a radiofrequency digital-to-analog converter (RF-DAC). The RF-DAC analog signal may be upconverted to a radar frequency and transmitted. A receiver may receive, downconvert, and analyze a reflection of the radar transmission, e.g.Type: GrantFiled: October 23, 2018Date of Patent: August 10, 2021Assignee: INFINEON TECHNOLOGIES AGInventors: Niels Christoffers, Sanaz Hadipour Abkenar, Soumya Krishnapuram Sireesh, Christoph Wagner

Patent number: 11079493Abstract: A system and method for testing the integrity of signals incoming to a satellite navigation system. The method is implemented with an array of antenna elements, and a receiver connected to each antenna element. The receivers simultaneously and continuously make measurements on all tracked signals. Each receiver measures the carrier phase of an incoming signal. Based on the carrier phase differences between antenna elements and the distance between them, the azimuth and elevation of the signal source can be calculated. This measured angle of arrival can then be compared to an expected angle of arrival to determine if the signal source is legitimate. The system and method can be also applied to determining the angle of arrival of sources of interference, and to mitigating the effects of both illegitimate and interfering signals.Type: GrantFiled: November 26, 2018Date of Patent: August 3, 2021Assignees: UHU Technologies, Southwest Research InstituteInventor: Thomas Howard Jaeckle
