Abstract: A cable containing an optical fiber is used to transmit data between an underwater remotely operated vehicle (ROV) and a support vessel floating on the surface of the water. The ROV stores the cable on a spool and releases the cable into the water as the ROV dives away from the support vessel. The ROV detects the tension in the cable and the rate that the cable is released from the ROV is proportional to the detected tension in the cable. After the ROV has completed the dive and retrieved by the support vessel, the cable can be retrieved from the water and rewound onto the spool in the ROV.

Abstract: The present invention is directed towards a fixed positively buoyant manned submersible that includes a plurality of vertical thrusters and a sealed enclosure(s) that can support one or more human passengers. The vertical thrusters can include vertically aligned propellers that are coupled to motors that control the rotational velocity of the propellers. The vertical thrusters to generate a negative vertical thrust to allow the submersible to dive within a body of water. Horizontal movement can be achieved through horizontal thrusters or directing the thrust vectoring of the vertical thrusters.

Abstract: A spool has a cylinder, a first flange coupled to a first end of the cylinder and a second flange coupled to a second end of the cylinder. A compressible material surrounds the cylinder and an optical fiber is wrapped around the compressible material. When tension is applied to the optical fiber the compressible material can be deformed to reduce the tension on the optical fiber. When submerged underwater the water pressure will not compress the compressible material.

Abstract: A cable containing an optical fiber is used to transmit data between an underwater remotely operated vehicle (ROV) and a support vessel floating on the surface of the water. The ROV pulls the cable through the water and as the ROV dives away from the support vessel, the optical fiber is released from the support vessel. Excess tension in the cable can damage the optical fiber and the tension can be highest close to the ROV. To prevent potential damage to the optical fiber, the ROV can store a portion of the cable and release the cable if the detected tension approaches the maximum working load. When the tension drops to a lower safe level, the release mechanism can stop releasing the cable.

Abstract: An optical fiber management system for a remotely operated vehicle (ROV) includes a spool containing a length of optical cable, a motor coupled to the spool, a motor controller, a speed sensor and a feed mechanism. The motor controller can detect the speed of the ROV through water and control the rotational speed of the motor so that the optical cable is removed from the spool at a speed that is equal to or greater than the speed of the ROV. A feed mechanism is used to apply a tension to the optical cable so that it is removed from the spool and emitted from the ROV without becoming tangled.

Abstract: An optical fiber cable has a transparent core for transmitting optical data and a biodegradable protective covering. When placed in water, the protective covering dissolves in water after a few days. The raw remaining optical fiber cover is very thin, approximately 0.003 inches in diameter and very fragile. The optical core is easily broken into fine particles which becomes sand on the sea floor.

Abstract: A system for communicating with a remotely operated underwater vehicle (ROV) includes a winged ROV coupled to a surface buoy by a tether. A controller on a support ship is coupled to the tether and the control signals are then transmitted through the tether to the ROV. Feedback and sensor signals are transmitted from the ROV through the wireless transceivers to the controller. The wings of the ROV produce negative lift which is greater than the buoyant force of the ROV and the vertical tension forces on the tether.

Abstract: A system used in a remotely controlled firearm device includes a circular gear and two worm gears. The worm gears engage the outer diameter of the circular gear and rotate synchronously to rotate the circular gear to align the firearm device with a target. Once the firearm device is aligned, the circular gear is locked into a fixed position that does not have any hysteresis by rotating the two worm gears asynchronously.
