    Abstract: A magnetic field measuring apparatus for measuring a to-be-measured magnetic field includes a magnetic impedance element with an impedance change rate that changes depending on the to-be-measured magnetic field, a drive signal providing section and a measurement range setting section. The drive signal providing section provides a drive signal to the magnetic impedance element. A measurement range setting section sets a measurement range in which the to-be-measured magnetic field can be measured. A relationship between the to-be-measured magnetic field and the impedance change rate is arranged to change depending on a frequency of the drive signal. The measurement range setting section is arranged to set the measurement range by setting the frequency.

  • Publication number: 20240094311
    Abstract: A signal vector derivation apparatus receives measurement results from a plurality of sensors that receive signals each represented by a vector having a predetermined direction and measure triaxial components orthogonal to each other and derives the direction of the vector. The measurement results from the sensors are each proportional to a sum of the triaxial components of the vector multiplied, respectively, by first coefficients. The signal vector derivation apparatus includes a spectrum deriving section and a direction deriving section. The spectrum deriving section derives a spectrum obtained based on the measurement results from the sensors and a sum of the first coefficients multiplied, respectively, by second coefficients, the spectrum having local maximum values within voxels in which signal sources that output the respective signals exist. The direction deriving section derives the direction of the vector based on the second coefficients used to obtain the spectrum.
