Classification: CPC A  G | IPC A  G

Claim 8:
9. The signal acquisition unit of claim 7, further comprising:
at least one magnetic field actuator configured for generating an actuated magnetic field that at least partially cancels an outside magnetic field, thereby yielding a total residual magnetic field at the magnetometer as the arbitrary magnetic field, such that the arbitrary magnetic field measurement reported by the magnetometer is a total residual magnetic field measurement reported by the magnetometer, and the determined amplitude of the arbitrary magnetic field at the magnetometer is a determined amplitude of the total residual magnetic field at the magnetometer;
wherein the at least one processor is configured for controlling the actuated magnetic field at least partially based on the total residual magnetic field determined at the magnetometer in a manner that suppresses the total residual magnetic field.
