Abstract: An apparatus for rotating a shaft, the apparatus includes an inner ring, an outer ring, a plurality of electromagnets positioned between the inner ring and the outer ring, a plurality of planar collector coils positioned around the inner ring, a battery electrically connected to the plurality of electromagnets and the plurality of planar collector coils, and a control system operatively connected to the battery and the plurality of electromagnets. The apparatus may further include a human machine interface in operative communication with the control system wherein the human machine interface is configured to receive as input from an operator a revolutions per minute for operation of the power generator. The apparatus may be a part of a vehicle such as a ship or other electric vehicle.

Abstract: An angled instrument assembly includes an angled sleeve, a driver shaft, and a tool bit. The angled sleeve includes a straight passage segment that meets an angled passage segment at a junction. The junction includes an inner elbow and an outer elbow. Material is removed from the inner surface of the inner elbow in order to improve the ease with which the driver shaft can be moved in and out of the angled sleeve. The assembly can also include drafted female or male engagement bodies for facilitating the engagement and disengagement of the tool bit with a tool bit engagement assembly located at the distal end of the driver shaft.
