Abstract: Apparatus includes a buoyant structure having a central vertical axis when floating in water and having at least one feature to reduce a rotation of the buoyant structure about the central vertical axis when floating in the water. The apparatus further includes an electronic camera assembly coupled to the buoyant structure. The electronic camera assembly is configured to generate an electronic image signal. The apparatus further includes a tubular structure coupled to the buoyant structure and configured to remain under the surface of the water. The tubular structure includes a watertight compartment and an electronic circuit assembly disposed within the watertight compartment. The electronic circuit assembly is coupled to receive the electronic image signal and is configured to generate an optical image signal representative of the electronic image signal. The apparatus further includes a fiber optic cable configured to carry the optical image signal.

Abstract: Apparatus for puncturing a gas filled bottle uses a spring force upon an inflator tack, which punctures the gas filled bottle, rather than a manual or explosive force. The spring force is retained prior to puncturing the bottle by a retention element disposed in a hole. The retention element is released upon actuation of the apparatus.

Abstract: A winged body has a wing structure with at least two wings coupled to a body structure, each wing having a wing tip. The wings wrap around the body structure when in a stowed configuration within a launch tube, and the wings spring outward from the body structure to a deployed configuration when the winged body is removed from the launch tube. The wings can take deformed-deployed configurations when the winged body is towed at a relatively high speed through the water.
