Technical Examples

An apparatus for maintaining the orientation of an instrument or other object in one embodiment includes an inner shell of ferromagnetic material. An outer shell surrounds the inner shell, and one or more electromagnets are attached to the inner surface of said outer shell. The powering of the electromagnets creates eddy currents in the inner shell, which create torques that orient and re-orient the position of the inner shell. In another embodiment, the outer shell has a plurality of ports that are supplied with a gas. Some ports function to levitate the inner shell, and other ports function to orient and re-orient the inner shell.
