Exemplary systems enable operation of mobile devices underwater. Antennas on a buoy assembly allow a mobile device to maintain wireless communications. A series of cable segments connect a buoy assembly to a waterproof case capable of sealing a mobile device.

Disclosed herein is a floating recovery device for underwater equipment. The device includes a recovery body partitioned into a first compartment, a second compartment, and a third compartment by a partition wall, first and second pressure tanks installed in the first and second compartments, respectively, first and second striking parts fastened to the first and second pressure tanks, respectively, to strike the first and second pressure tanks, first and second actuators wirelessly actuating the first and second striking parts, respectively, and a buoyancy generator installed in the third compartment, and inflated by high-pressure gas introduced from the first and second pressure tanks, thus generating buoyancy. Such a configuration allows the pressure tank to be wirelessly struck for the purpose of supplying high-pressure gas to the buoyancy generator and floating the underwater equipment in the event of the loss of the underwater equipment.

An underwater docking station for communication with underwater devices. The underwater docking station comprises a support structure and an optical communication module configured for communication with said underwater devices along an optical communication axis. The station also comprises an actuator active on the optical communication module to move the optical communication axis between operative positions, wherein, in the first operative position, the communication axis is directed along a first communication direction, and, in the second operative position, the communication axis is directed along a second communication direction different from the first communication direction. The station further comprises a control unit connected to the optical communication module to manage a communication with said underwater devices, and the actuator to drive the optical communication axis to the first operative position and to the second operative position.

Provided is a mobile object including: a mobile object information transmitting unit configured to transmit, to another mobile object by optical wireless communication by a first optical wireless communication unit, first mobile object information including first inertial measurement information and first body control information; a mobile object information receiving unit configured to receive, from the another mobile object by optical wireless communication by the first optical wireless communication unit, second mobile object information including second inertial measurement information and second body control information; and an optical axis direction control unit configured to control a direction of an optical axis of the first optical wireless communication unit on a basis of the first mobile object information and the second mobile object information.

A method and apparatus for connecting a V2X-enabled terminal to a local vehicle-to-everything (V2X) server is provided. A communication method of a terminal of the present disclosure includes transmitting mobility information of the terminal to a macro vehicle-to-everything (V2X) server performing V2X communication with the terminal, receiving provision information for connection to a local V2X server taking charge of an area predicted as a next-hop area to which the terminal moves from the macro V2X server, and establishing, when the terminal enters the next-hop area, a connection to the local V2X server for V2X communication based on the provision information.

A multiple services system through sensors having a central monitoring unit for vessels, consisting of a central monitoring unit and a set of sensors being connected to each other in a wireless way, and being susceptible to establish communication through the central monitoring unit with a remote user.

This application relates to an apparatus for tracking location using a control platform of a small buoy for simulating marine pollutants, in which at least one small observation buoy floats on the ocean, and a relay buoy collects location information from the observation buoy and provides the collected location information to a weather information management server. The apparatus may include at least one observation buoy and a relay buoy, the observation buoy including a GPS receiver which receives a signal transmitted from a GPS satellite and generate location information. The apparatus may also include a communicator performing wireless transmission and reception of signals with the relay buoy, and a power source providing driving power to the GPS receiver and the communicator. The relay buoy may receive location information from the at least one observation buoy and provide the received location information to a weather information management server.

A mooring buoy comprising a buoyant body, an attachment point for attaching the buoy to a marine vessel, a controller, an RF communication device for receiving a vessel ID identifying the marine vessel and a movement sensor, wherein the controller is arranged to determine when the marine vessel is moored to the mooring buoy based on the received vessel ID and the movement sensor.

An inflatable deployable mast fairing assembly is provided with a rigid foundation, a hydrodynamic fairing and at least one soft actuator. The hydrodynamic fairing is shaped to close an aperture formed between a deployable hardware system and a sail bay opening. A first soft actuator connects to the rigid foundation at one end and to the hydrodynamic fairing at another. Fluid pressurization elongates a first soft actuator coaxial to the deployable hardware system to fittedly position the fairing in the aperture with a void in the fairing to receive the hardware system. If the rigid foundation is sail-mounted, a second soft actuator connects to the sail-mounted foundation opposite the first soft actuator and to a counter flange mechanically connected to the hydrodynamic fairing. A second pressurization elongates the second soft actuator coaxial to the deployable hardware system to retract the hydrodynamic fairing from the aperture.
