  • Patent number: 11366220
    Abstract: A method is disclosed for designing a sparse array for an automotive radar. The method moves each of a number of antenna elements to candidate neighboring grid positions starting from an initial random seed placement to iteratively search for a placement of antenna elements that improves upon a cost function. The cost function for each candidate placement may be determined from characteristics of the FFT response associated with the candidate placement. The method may search for a candidate placement with the lowest cost function among the multiple candidate placements based on the random seed placement. The search may be repeated for a large number of random seed placements to find the candidate placement with the lowest cost function corresponding to each random seed placement. The method may compare the lowest cost functions corresponding to the multiple random seed placements to determine an optimized placement having the minimum cost function.

  • Patent number: 11366142
    Abstract: A measurement module receives crosstalk compensation factors that include distance factors based on respective distances of a current sensor of the module from respective current sensors of other measurement modules and phase difference factors based on respective differences between the phase of a source current measured by the module and respective phases of source currents measured by the other modules. The module monitors messages reporting current measurements transmitted from the other modules connected to a broadcast bus, of current measurements made by respective current sensors of the other modules measuring other respective source currents. The module determines a reported current that is computed as a function of current measurement by the module's current sensor, reported current measurements monitored from the other modules, and the received crosstalk compensation factors. The module transmits the determined reported current over the broadcast bus to the other modules and a central controller.

  • Patent number: 11333690
    Abstract: A measurement module uses harmonic compensation factors to minimize the effects of harmonic distortion in measurements of a source current by a current sensor of the module. The module samples at a first sampling rate, measurements of the source current to generate a first current measurement. The module samples at a second sampling rate higher than the first sampling rate, for an interval of time, measurements of the source current to generate a second current measurement. The module determines a harmonic compensation factor based, at least, on a difference between the first current measurement and the second current measurement. The module determines a reported current computed as a function of at least the first current measurement, the difference between the first current measurement and the second current measurement, and the harmonic compensation factor. The reported current represents a magnitude of the source current adjusted by the harmonic compensation factor.

  • Patent number: 11280173
    Abstract: A system or method for drilling includes autonomously controlling a rotary or percussive drilling process as it transitions through multiple materials with very different dynamics. The method determines a drilling medium based on real-time measurements and comparison to prior drilling data, and identifies the material type, drilling region, and approximately optimal setpoint based on data from at least one operating condition. The controller uses these setpoints initially to execute an optimal search to maximize performance by minimizing mechanical specific energy. Near-bit depth-of-cut estimations are performed using a machine learning prediction deployed in an embedded processor to provide high-speed ROP estimates. The sensing capability is coupled with a near-bit clutching mechanism to support drilling dysfunction mitigation.
