Abstract: The invention relates to magnetorheological (MR) fluid devices (20) and the process of controlling the force in exercise equipment by utilizing the MR fluid devices. The MR fluid devices include rotary and linear acting varieties and are useful for controlled forces in exercise bicycles, recumbent exercisers, ski machines, rowing machines, and stair stepper machines. The rotary MR fluid device is comprised of a rotor (26) supported by bearings (44) and received within a housing (22). An MR fluid is received adjacent the rotor (26) and within a cavity (28) in the housing (22) and the MR fluid is controlled by an applied magnetic field to vary the operating torque resistance. Spring biasing (43) the rotor (26) allows for relaxed tolerances. Optimization of the Ri/Ro ratio is described which reduces the size and weight of the device (20). The linear acting version utilizes simple extensible pumps and an external MR fluid valve to provide a modularized system.

Abstract: A controllable fluid damper (22) is employed in a seat suspension system. A microprocessor (42) receives successive signals from a displacement sensor (44) and computes a rate of displacement. This displacement rate is used to determine an appropriate control signal for the damper (22) to provide the desired isolation of the seat occupant from the vibration input to the frame. A rate control method is disclosed as a preferred control technique for providing the desired isolation.

Abstract: A method for automatically calibrating a controller (44) for a controllable damping system (40), for example, the suspension and damping system for a truck seat or cab, includes the steps of receiving an initiation signal that is checked against criteria to ensure that calibration is actually intended. The seat (20) or other body (ex. a vehicle cab) is then moved to a first limit position, where a sensor (50, 50') reads a position signal, and to a second limit position, where another position signal is read. Preferably, a midpoint, or neutral position is calculated from the measured position signals, and the seat (20) or other body is moved to this neutral position. A range of movement is determined from the first and second position signals. Preferably, end stop limits are calculated based upon the limit values, and more preferably as predetermined fractions of the range of movement value. All values are stored for use by the controllable damper system (40).
