Abstract: An exercise treadmill has a plurality of shock absorbing springs which are disposed between a tread supporting subframe and a floor engaging frame. The springs are inserted into vertically oriented sleeves which are secured to the floor engaging frame. Posts extend downward from the subframe and into the sleeves and ride on the tops of the springs.
Abstract: A computer controlled exercise machine in which the user selects an exercise mode and its profile by programming the computer. Signals are produced by the program to control a resistive force producing device. Sensors produce data signals corresponding to the force applied to the actuating member of the system, velocity of movement and angular position which are continuously sampled at a high rate by a microprocessor operating under control of the program. The sampled data values are used to update and display performance results for the exercise and to compute the values of other parameters and, in some exercise modes, to control the amount of the resistive force.

Abstract: A hydraulic exercise machine which employs the use of a fluid actuator and a servo pump mechanism controlled by an integrated microprocessor device. The dedicated microprocessor control is pre-programmed to provide the user with three (or more) exercise modalities; a manual mode, in which the user independently selects the concentric and eccentric force values; a pyramid mode, in which the user selects an automatic increasing progression of concentric and eccentric force values, which upon user failure to complete a full repetition, automatically reverses the force value progression; and a maximum strength test or exercise program, in which the user applies maximal muscular force against the resistance in both the concentric and eccentric phase of the exercise. Various performance parameters are displayed and recorded in real time.
Abstract: A rotatable exercise mechanism for interacting with the body in order to perform exercises. The rotatable exercise mechanism includes a pulley mounted on the frame. A cable is secured to the pulley such that the cable can be wound in opposite directions about the pulley. As the pulley is rotated in either a clockwise or counter-clockwise direction, the cable is both paid out from and wound onto the pulley. An adjustable resistive force is supplied for interacting with the cable being wound onto or paid out from the pulley. A crank for applying a rotative force to the pulley is also supplied. The pulley is rotated by applying a rotative force to the pulley capable of overcoming the resistive force applied to the cable.
