Electrical signature analysis to quantify human and animal performance on fitness and therapy equipment such as a treadmill
First Claim
Patent Images
1. A method of analyzing a physical condition of a subject human or animal, comprising:
- sensing a waveform using a current sensor, the waveform representing an electrical current supplied to a fitness and therapy device;
recording the waveform in a data acquisition device;
rectifying the waveform;
identifying in the rectified waveform a plurality of waveform peaks for each of a plurality of strides taken by the subject;
using the plurality of waveform peaks per stride to construct a stride profile;
using the stride profile to determine a first average stride signature and a second average stride signature that are representative of the subject'"'"'s physical condition based on the stride profile.

Abstract
The invention is a human and animal performance data acquisition, analysis, and diagnostic system for fitness and therapy devices having an interface box removably disposed on incoming power wiring to a fitness and therapy device, at least one current transducer removably disposed on said interface box for sensing current signals to said fitness and therapy device, and a means for analyzing, displaying, and reporting said current signals to determine human and animal performance on said device using measurable parameters.
