Abstract
The present invention is drawn to a method of stabilizing the motion of a levitated object. The method involves continuously determining the motion of a levitated object, relative to a given point, and deriving the velocity of the object from the determined motion. A continuous, non-contact, corrective force is applied to the object in the opposite direction and proportional to the derived velocity.
