Injured muscle developing appliance - incorporates force pick=up and memory to store max. force signal, with clock to set exercise times

摘要

The muscle rehabilitating equipment incorporates an energy pick-up for determining the maximum force exerted by the user. The low voltage generated is amplified and measured by means of two voltmeters. The highest amount is automatically conveyed to a memory. The duration of the various cycles is set by an electric clock, and two potentiometers. Sound and visual signals give the alarm when the optimum force is not reached.
