Solution Approach 2:

The patent replaces manual mechanical adjustment mechanisms with automated computational generation. The sensitivity curve is no longer adjusted through complex manual calibration but is automatically generated by a system that processes user input parameters and computes the complete acceleration profile, simplifying the operation while maintaining precision

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
