<p>A multi-mode exercising apparatus, which includes an exercising member, a rotary actuator coupled to the exercising member controlling its movement in response to fluid flow therethrough and a servo-valve means coupled to the actuator for controlling both the direction and rate of fluid flow through the actuator in response to a input electrical signal. A hydraulic pump is used for pressurizing the fluid and a motor means for driving the pump. The hydraulic fluid is stored in a reservoir. Means are provided for monitoring the angular position of the actuator and a load cell means coupled to the member provides a signal proportional to the magnitude of force applied directly to the member. A microprocessing means is used for controlling the input electrical signal to the servo valve in response to the signal of the load cell, the angular position of the actuator, program means stored in the microprocessor and calibration data.</p> |
