US Patent 8157708 Sensing applications for exercise machines

Sensing applications for exercise machines are described. An example sensing application for profiling a workout session of an exercise machine comprises a user interface to input physical characteristics or workout parameters. A sensor is operatively coupled to the exercise machine to generate an output signal in proportion to a magnitude of a force imparted on the exercise machine in response to an impact to the exercise machine. A control system processes the output signal to determine a magnitude of a peak or trough value of the output signal, where the control system is to process the peak or trough value of the output signal to profile the exercise session.
