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.

Method and apparatus for stabilizing levitated objects

An acoustic levitator device for suspending a specimen object under the influence of gravity without contact with a solid surface comprising in combination gas levitation means for directing a concentrated flow of gas along an axis upwardly against the object to provide a force to lift a majority weight of the object, and acoustic levitation means for exerting an acoustic positioning force on said object to restrain movement away from said axis and to hold said object in a given position.

Aero-acoustic levitation device and method

An acoustic levitator includes a pair of opposed sound sources which have interfering sound waves producing acoustic energy wells in which an object may be levitated. The phase of one sound source may be changed relative to the other in order to move the object along an axis between the sound sources.

Method and apparatus for acoustic levitation

A sound transducer having a high impedance relative to air is coupled with mechanical transformers. The output transformer is in the shape of a dish having the center coupled to a piezoelectric transducer, the outer portion of the dish is unsupported and more flexible than the center section at resonance this allows large amplitude movement and a better impedance match to air.
