Patent ID: 11921177
Assignee: KONINKLIJKE PHILIPS N.V.
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 12:
13. An electronic device, comprising:
an integrated circuit (IC) chip;
a magnetic field sensor configured to measure an ambient magnetic field measurement signal;
a plurality of electrically conductive loops or windings disposed around the IC chip; and
an electronic controller configured to:
determine an orientation of the electronic component with respect to a direction of an ambient magnetic field from the ambient magnetic field measurement signal measured by the magnetic field sensor;
determine at least one magnetic field shim current based on the determined orientation of the electronic component with respect to the direction of the ambient magnetic field, and a calibration table which maps various orientations of the electronic component with respect to the direction of the ambient magnetic field, to corresponding magnetic field shim currents; and
energize the plurality of electrically conductive loops or windings to flow the determined at least one magnetic field shim current.
