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

Claim 0:
1. An electronic device, comprising:
an electronic component;
at least one electrically conductive loop or winding)-disposed around the electronic component; and
an electronic controller configured to:
determine an orientation of the electronic component with respect to a direction of an ambient magnetic field, from a received ambient magnetic field measurement signal;
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 at least one electrically conductive loop or winding to flow the determined at least one magnetic field shim current.
