  • Vector sensor for measuring particle movement in a medium
    Patent number: 9835489
    Abstract: The present invention relates to a vector sensor for measuring particle movement in a medium. The vector sensor comprises a magnetic body that is held at a certain distance from a magnetometer in such a way that the magnetic body can move in time with a passing particle movement, wherein the magnetometer is arranged to detect the oscillations in the magnetic field that the movements in the medium produce.
    Type: Grant

  • Method of estimating target signals by a dynamical fluxgate sensor
    Patent number: 7009392
    Abstract: A method of estimating target signals (dc or low frequency signals) by a dynamical fluxgate sensor and a low-power fluxgate magnetometer operating according to the method. The sensor is pre-biased with a periodic bias signal in the form of a superposition of a square wave and a triangular wave. The change in residence time statistics in the stable state of the sensor is analyzed for estimating the target signals.
