MEASURING LOAD

摘要

An indication of the displacement of a spring or alternatively of the load applied thereto is obtained by sensing the change of inductance of the spring as it is displaced or as load is applied thereto. Examples are given of use of this technique for applications as diverse as safe use of trampolines, construction of joysticks, wave detection, monitoring the displacement of a platform with six degrees of freedom, loading of a ship by a crane at a dock, aircraft undercarriage accident investigations and analysis of the performance of a boxer or of a sportsman in a ball sport.
