  • Line voltage compensation system for power chair
    Publication number: 20050077850
    Abstract: An apparatus, method and program product position a powered examination chair at a constant, desired speed despite fluctuations line voltage. A power signal supplied to an actuating motor of the chair is apportioned according to the line voltage supplied to the chair. The desired speed may be customized by a user in the field.

  • Load compensation system for power chair
    Publication number: 20050077861
    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.
