  • Adaptive position detection for inductive linear position sensing
    Patent number: 11719525
    Abstract: Methods and systems for determining a position of a structure using inductive position sensing are described. In an example, a processor may receive a plurality of data points representing a plurality of voltages. The plurality of voltages may be generated by a plurality of sensor coils based on a magnetic flux field. The magnetic flux field may be generated by a plurality of driver coils, and the plurality of voltages may vary with changes in the magnetic flux field. The processor may calibrate the plurality of data points to generate a plurality of calibrated data points. The processor may filter the plurality of calibrated data points. The processor may estimate a position of the structure based on the filtered calibrated data points, where the position of the structure may indicate a size of a size changing device.
