Method and apparatus for providing a dynamically variable resistive load during exercise
First Claim
1. A method for providing a dynamically variable resistive load during exercise, the method being implemented using an apparatus that includes a wheel unit that is operable so as to rotate in response to exertion of a user-applied force during an exercise stroke, a resistance generator that is operable so as to generate a resistive torque for resisting rotation of the wheel unit when the user-applied force is exerted, and an electrically controlled torque transfer device that couples the resistance generator to the wheel unit and that is operable so as to transfer a fraction of the resistive torque from the resistance generator to the wheel unit, the method comprising the steps of:
- a) detecting angular rotation of the wheel unit during each exercise stroke; and
b) in accordance with the detected angular rotation of the wheel unit during a current exercise stroke, controlling the torque transfer device to adjust the fraction of the resistive torque that is transferred to the wheel unit.

Abstract
An apparatus for providing a dynamically variable resistive load during exercise includes a wheel unit, a resistance generator, a torque transfer device, an angle measuring device, and a control unit. The wheel unit rotates in response to exertion of a user-applied force during an exercise stroke. The resistance generator generates a resistive torque for resisting rotation of the wheel unit when the user-applied force is exerted. The torque transfer device transfers a fraction of the resistive torque from the resistance generator to the wheel unit. The angle measuring device detects angular rotation of the wheel unit during each exercise stroke. The control unit, in accordance with the angular rotation of the wheel unit during a current exercise stroke, controls the torque transfer device to adjust the fraction of the resistive torque that is transferred to the wheel unit.
