Abstract: In this paper we describe a new magnetometer sensor head which is capable to measure the complete calibration circle as one data sample. The new sensor allows for online determination of ...

Raw magnetometer measurements ideally lie on a sphere centered at the origin. Due to hard-iron effects, the sphere is displaced (biased). A least-squares sphere fitting algorithm is applied first to ...

A magnetometer with 1,000 times the energy efficiency and 1/100th the amount of noise By applying our uniquely designed integrated circuit for measurements to the magneto-impedance element, we created ...

Smartphone magnetometer readings exhibit high linear correlation when two phones coexist within a short distance. Thus, the detected coexistence can serve as a proxy for close human contact events, ...
