  • Method and device for measuring a magnetic field by synchronised excitations
    Patent number: 9797966
    Abstract: The invention relates to a magnetic field measurement device, including a detector (4) configured to measure the amplitude of an output signal at a harmonic of an oscillation frequency of an excitation source, said amplitude being proportional to the magnetic field (B) to be measured, characterised in that it comprises an excitation circuit configured to associate with a principal excitation source (B1cos?t) oscillating at a principal oscillation frequency at least one secondary excitation source (B2cos(?/3t+?2)) oscillating at a secondary oscillation frequency that is a fraction of the principal oscillation frequency, said fraction being odd if said harmonic is odd, and even if said harmonic is even.
    Type: Grant

  • MAGNETIC SHIELDING
    Publication number: 20160157394
    Abstract: A magnetic shielding including at least one side wall defining a cavity to contain an object to be magnetically isolated. The side wall includes between three and five layers of ferromagnetic metallic material and between three and five layers of polymer material including a ferromagnetic powder. Two adjacent metallic layers are separated by a polymer material layer.
