ABSTRACT:
An apparatus and method positions a powered examination chair at a constant, desired speed. The desired speed is achieved irrespective of patient weight and/or direction of chair travel. A power signal supplied to an actuating motor is apportioned according to a load incident on the chair. The determined load accounts for patient weight, as well as to gravitational and mechanical forces.
