Abstract
An underwater assembly includes: a hull having an internal cavity that is in fluid communication with the external environment; an inductive actuator mounted within the cavity of the hull; a current source mounted in the hull and electrically connected to the actuator; and a movable member connected with the actuator and positioned external of the hull. Provision of current to the actuator causes the movable member to move relative to the hull.
Claims25
An underwater assembly, comprising:
- a hull having an internal cavity that is in fluid communication with the external environment;
- an inductive actuator mounted within the cavity of the hull;
- a current source mounted in the hull and electrically connected to the actuator;
- and
- a movable member connected with the actuator and positioned external of the hull;
- wherein the provision of current to the actuator causes the movable member to move relative to the hull.

A method of controlling the orientation of a movable member on an underwater assembly, comprising:
- (a) providing an underwater assembly, comprising:
- a hull having an internal cavity that is in fluid communication with the external environment;
- an inductive actuator mounted within the cavity of the hull;
- a current source mounted in the hull and electrically connected to the actuator;
- and
- a movable member connected with the actuator and positioned external of the hull;
- (b) receiving instructions at a controller, the instructions providing information associated with the position of a movable member;
- (c) generating current in the actuator with the current source, wherein the magnitude of the current generated is determined by the instructions received at the controller, the current generated in the actuator causing the movable member to take a predetermined position relative to the hull.
