1. A method for analyzing positions, executed by a microprocessor from a non-transitory computer-readable storage medium, comprising:

  • obtaining a sensing information;

    determining, by the microprocessor, at least a first initial position in the sensing information based on a first threshold;

    performing, by the microprocessor, a zero-crossing position analysis starting from each first initial position in a first range in a first direction to determine the position of a zero-crossing, wherein each zero-crossing is between a positive and a negative value.
