A method and a system may inductively determine a position of a display screen of a computing device. Associated processes may generate a magnetic field by providing an alternating current to a driver coil, and may generate a voltage at a sensor coil in response to the magnetic field. The system and method may additionally include determining a linear position of the display screen by executing an algorithm at a processor. An input to the algorithm may include voltage data associated with the voltage generated at the sensor coil. The linear position of the display screen may correspond to a size of the display screen between a minimum size and a maximum size.

Display screen position sensing using inductive sensing

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.
