Abstract
An improved system and method for floating an object is disclosed by the present invention. The system includes an electromagnetic source for accommodating a wide weight-range of objects to be floated and for providing intelligent, responsive control of the system. The electromagnetic source includes a single Hall effect sensor for sensing the position change of the floating object and a microprocessor for intelligently controlling the floating object so that a better, simpler, and more stable operation is achieved. With the implementation of the microprocessor, a user friendly interface for initially placing the object on the system is achieved, and no complicate adjustments of the system are required to float a new object.
