The apparatus and system in the present invention not only can be used for submarine structure detection, but also can be used for earthquake disaster and tsunami warning, and can implement autonomous energy supply, long timing, and unattended operation.

An underwater drone is disclosed. The underwater drone includes a horizontal propeller module and a vertical propeller module to respectively provide a drone body with a horizontal proceeding force and a vertical lifting or diving force. The underwater drone includes a horizontal channel and a vertical channel, which allow the water to pass through for reducing resistance when the underwater drone moves forwards, upwards or downwards. The underwater drone is equipped with a buoy member with an antenna portion of a communication module disposed therein. The underwater drone is equipped with the fishing device, the fish finding device and the image capturing module. Therefore, the underwater drone is capable of fishing, rapidly moving and wireless remote control.

A method and apparatus for raising a self-propelled pool cleaner from a surface of a pool. The cleaner includes an interior chamber, a lower portion with an inlet and an upper portion with an outlet. Rotatably-mounted supports guide the cleaner along the pool surface. An interior water pump draws water/debris through the inlet, the debris is filtered in the interior chamber, and filtered water exits through the outlet to propel the cleaner during a cleaning operation. A buoy assembly is tethered to the cleaner via a retractable cable. When the cleaner is submerged, the cable is released and the buoy assembly floats on the water surface while tethered to the submerged cleaner. The cleaner can receive a command signal from a controller to exit from the pool, and the cable is retracted to cause the cleaner to rise from the submerged surface of the pool.

Disclosed is a novel type of computing apparatus which is integrated within a buoy that obtains the energy required to power its computing operations from winds that travel across the surface of the body of water on which the buoy floats. Additionally, these self-powered computing buoys utilize their close proximity to a body of water in order to significantly lower the cost and complexity of cooling their computing circuits. Computing tasks of an arbitrary nature are supported, as is the incorporation and/or utilization of computing circuits specialized for the execution of specific types of computing tasks. And, each buoy's receipt of a computational task, and its return of a computational result, may be accomplished through the transmission of data across satellite links, fiber optic cables, LAN cables, radio, modulated light, microwaves, and/or any other channel, link, connection, and/or network.

A computer-implemented method, computer program product, and computer system may include determining, by a computing device, a first location on a body of water. The first location may be transmitted to a drone buoy. Data may be received from the drone buoy. A second location on the body of water to send to the drone buoy may be determined based upon, at least in part, the data received from the drone buoy.

An underwater body having a movable component which can be moved into a retracted position and, as a result, increases the volume of the underwater body. In addition, a method is disclosed for operating such an underwater body. An expansion means conducts a fluid into a hollow space. The hollow space is operatively connected to the movable component. When the fluid is conducted into the hollow space, the movable component is moved into the extended position relative to the shell of the underwater body. The fluid in the hollow space hardens. The hardened fluid in the hollow space holds the movable component in the extended position.

A buoy includes a surface unit comprising a sealed tank comprising an inflatable bag, a tubular wall of axis z and a bottom, the tubular wall and the bottom delimiting a volume referred to as the inner volume, the surface unit comprising at least one cartridge enclosing a compressed gas that can be released in such a way as to inflate the inflatable bag such that it functions as a float in an operational configuration of the buoy, and the sealed tank comprises a projecting container protruding from the bottom and extending out from the inner volume, from the bottom.

Systems and methods for deployment and retrieval of ocean bottom seismic receivers. In some embodiments, the system includes a carrier containing receivers. The carrier can include a frame having a mounted structure (e.g., a movable carousel, movable conveyor, fixed parallel rails, or a barrel) for seating and releasing the receivers (e.g., axially stacked). The structure can facilitate delivering receivers to a discharge port on the frame. The system can include a discharge mechanism for removing receivers from the carrier. In some embodiments, the method includes loading a carrier with receivers, transporting the carrier from a surface vessel to a position adjacent the seabed, and using an ROV to remove receivers from the carrier and place the receivers on the seabed. In some embodiments, an ROV adjacent the seabed engages a deployment line that guides receivers from the vessel down to the ROV for on-time delivery and placement on the seabed.
