Abstract
An apparatus for measuring the power generated by a person who is performing physical activity and displaying a readout of such measurement to the user. The apparatus senses and measures the motion of a mass that the person is moving and/or working against, derives position, velocity, and acceleration data and calculates power. The person thereby gains benefit of such information in real time.
