FLUXGATE MAGNETIC SENSOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 17956758 titled 'FLUXGATE MAGNETIC SENSOR

Simplified Explanation

The patent application describes an apparatus with two coils, a control circuit, and a processing circuit, where the control circuit selects a field strength level and provides a signal representing the selected level, while the processing circuit sets a state representing the polarity of a magnetic field sensed by the second coil.

  • The apparatus comprises a first coil and a second coil that are magnetically coupled to each other.
  • The control circuit selects a field strength level from a set of discrete levels based on a control input and provides a signal representing the selected level.
  • The processing circuit sets a state representing the polarity of a magnetic field sensed by the second coil based on a second signal across its inputs.

Original Abstract Submitted

In some examples, an apparatus comprises a first coil, a second coil, a control circuit, and a processing circuit. The second coil is magnetically coupled to the first coil. The control circuit has a signal output coupled to the first coil, and a control output, and the control circuit configured to: responsive to a state of the control input, select a field strength level from a set of discrete field strength levels; and provide a first signal representing the selected field strength level at the signal output. Also, the processing circuit has processing inputs and a processing output, the processing inputs coupled to the second coil, the processing output coupled to the control input, and the processing circuit configured to, responsive to a second signal across the processing inputs, set a state of the processing output representing a polarity of a magnetic field sensed by the second coil.
