  • Flat power coil for wireless charging applications
    Patent number: 9225392
    Abstract: A coil assembly is disclosed. The coil assembly includes a coil that is provided on a substrate. The coil includes a trace element that is wound on the substrate. The trace element includes an interior gap that extends or is present along at least a portion of the trace element. The interior gap is dimensioned to reduce a presence of eddy currents that would otherwise be generated when the coil is active to inductively transmit or receive signals.
    Type: Grant
    Filed: March 9, 2011
    Date of Patent: December 29, 2015
    Assignee: QUALCOMM Incorporated
    Inventors: Michael Lehr, Manjirnath Chatterjee, Dyke Shaffer, Eric Liu

  • Power bridge circuit for bi-directional inductive signaling
    Patent number: 8437695
    Abstract: An inductive signal interface comprises a coil assembly including one or more inductive coils, a bridge circuit including a plurality of switches, and control circuitry. The control circuitry is configured to individually operate the plurality of switches to enable the inductive signal interface to dynamically switch between a power-transmit mode and a power receive mode.
