  • MULTI-LAYER PARALLEL PLANE INDUCTOR WITH FIELD CONTROL POCKETS
    Publication number: 20220159795
    Abstract: A high current multi-layer parallel plane inductor is formed from a plurality of electrically conductive continuous layers folded back and forth to form a compact series inductor with each one of the plurality of electrically conductive layers having one or more layer pocket holes with layer edge notches forming one or more coil control pockets that generate a magnetic field pattern when alternating current is applied to the inductor.

  • Antenna array calibration
    Patent number: 10371822
    Abstract: An apparatus for performing calibration of an antenna array having a plurality of antennas including at least a first antenna and a second antenna. The apparatus includes a global navigation satellite system receiver configured to measure a first phase of a first signal received by the first antenna from a satellite and a second phase of a second signal received by the second antenna from the satellite. The apparatus also includes at least one processor configured to receive the first phase and the second phase from the global navigation satellite system receiver and to operate in a calibration mode to determine a difference between the first and second phases.
