Abstract:
An annunciator for an organ stimulating system encapsulated within a casing and implantable in the body of a person comprising:a canister mounted on the casing of the organ stimulating system, said canister having a cylindrical internal cavity with a longitudinal axis, an inner peripheral surface, an inside diameter, and opposed inner terminal surfaces;a first electrically conductive coil encircling said canister and lying in a first plane;a second electrically conductive coil encircling said canister and lying in a second plane transverse to the plane of said first conductive coil and intersecting said first electrically conductive coil along the longitudinal axis of the internal cavity of said canister;a cylindrical permanent magnetic roller rotatable about a longitudinally extending roller axis having an outer peripheral surface engageable with said inner peripheral surface of said canister and being freely rotatable within the internal cavity thereof, said permanent magnetic roller being magnetized at right angles to the roller axis producing a permanent magnetic field; andmeans for sequentially energizing said first and second coils to produce a rotating magnetic field interacting with said permanent magnetic field of said magnetic roller to thereby cause said magnetic roller to roll about the internal cavity of said canister engaged with said inner peripheral surface, said permanent magnetic roller, by its movement, producing vibrations which are imparted to the casing of the organ stimulating system.
