Patent ID: 6899656

Claim:
A method of providing load control for an exercise apparatus, the apparatus comprising an exercise bar, a means for measuring the displacement over time of the exercise bar, horizontal and vertical actuators connected to move the exercise bar, a computer for generating horizontal and vertical actuator signals operatively connected to the means for measuring the displacement of the horizontal and vertical actuators and the computer; the method comprising: programming the computer to generate actuator signals for a predetermined exercise activity; generating displacement signals from the means for measuring the displacement over time of the exercise bar; transmitting the displacement signals to the computer; calculating, in the computer, the speed and acceleration of the exercise bar; calculating, in the computer, one or more actuator signals sufficient to maintain the speed, displacement, or force parameters for the predetermined exercise activity; and, transmitting the actuator signal to the actuators, so that the actuators move the exercise bar according to the predetermined exercise activity.
