  • Magnetic shield
    Patent number: 12601801
    Abstract: An active magnetic shield system, including an array of magnetic field sensors arranged to sense a local magnetic field. An array of magnetic field elements are arranged produce a magnetic field. Each magnetic field element has a unit coil for mounting to a plurality of surfaces arranged in at least 3 planes to define an enclosed cancellation volume, and to produce a vector magnetic field pattern.
    Type: Grant
