Abstract:

TDA Research, Inc proposes to develop a compact, low power, high life-cycle computer controlled Programmable Force Generator (PFG) that can generate any force between 0 and 700 lbf during any phase of the exercise motion. The proposed device uses a closed loop control system to maintain the predetermined load throughout the range of motion by controlling an electric motor. The force applied during the eccentric phase is independent of the force applied during the concentric phase; the force applied during the eccentric phase (return stroke) can even exceed the force applied during the pull stroke (concentric phase).The PFG uses regenerative braking to store the braking energy harvested during the pull stroke and applies this energy to provide the motive force during the return stroke. The PFG can be integrated with both the hardware and the software of existing exercise equipment such as the Advanced Resistive Exercise Device (ARED). Since the application of force can be automatically controlled during the entire range of motion, the PFG eliminates the need for the user to adjust the equipment to their specific range of motion; this significantly increases the fraction of time that can be spent exercising relative to the time spent configuring equipment.
