Abstract: A control system adapted for a boat having a first sensor including a GNSS receiver detecting a position of the boat, and a second sensor detecting the position of the boat is provided. The control system includes a control unit having a processor, configured to: switch a control mode of the control unit to an automatic docking mode; obtain roof information regarding whether a berth for mooring the boat includes a roof wherein when the control unit determines the berth for mooring the boat includes the roof, the control unit switches, at a predetermined timing, from the first sensor to the second sensor for determining the position of the boat.

Abstract: A control system, adapted for a boat having a first GNSS receiver disposed at a bow side of the boat, and a second GNSS receiver disposed at a stern side of the boat, the control system includes a control unit including a processor configured to determine whether an approach direction of the boat to a berth is bow first or stern first; and select, based on the approach direction, the first GNSS receiver or the second GNSS receiver for determining a position of the boat.

Abstract: An automatic berthing system and method for a vessel are provided. The automatic berthing system comprises a controller, controlling the vessel; an input part, receiving an input to perform the automatic berthing mode; at least one peripheral sensor, detecting position information and speed information of another vessel other than the vessel to determine whether a wake caused by the another vessel has influence on the vessel. The controller performs an automatic berthing control when the input to perform the automatic berthing mode is received until the vessel reaches a berthing position, and the controller stops the automatic berthing control when the another vessel is located within a predetermined distance from the vessel based on the position information.

Abstract: An autonomous control system and method for a vessel are provided. The autonomous control system includes a route setting unit, setting a route to a destination; a disturbance data acquisition unit, acquiring disturbance data from sources other than the vessel; an autonomous control unit, performing a control of the vessel based on the route set by the route setting unit and corrects the control of the vessel based on the disturbance data acquired by the disturbance data acquisition unit.

Abstract: A wireless communication method collects data generated from a plurality of moving entities. The wireless communication method includes performing first communication in which a control device controls a condition of data forwarding in the plurality of moving entities, via long-distance wireless communication; performing second communication that includes carrying out communication between one of the moving entities and a relay, or communication among the plurality of moving entities, via short-distance wireless communication, by using a DTN (Delay Tolerant Network), which employs a store-carry-and-forward process; and performing third communication that includes carrying out communication between the control device and the relay, or communication between the control device and one of the moving entities, via wired communication or the long-distance wireless communication.

Abstract: A system for treating waste water using a particulate body formed by covering and fixing nitrifying bacteria. In the system, the particulate body is inserted in a nitrifying vessel which including therein an air diffusion device for supplying oxygen to the nitrifying bacteria and a particulate body separation device for preventing the outflow of the particulate body. The nitrifying vessel and the particulate body contained therein are used as a nitrifying vessel unit and one or more such nitrifying vessel units are arranged within a treating tank. Waste water is circulated between the nitrifying vessel and the other portions of the treating tank than the nitrifying vessel by means of the air lift effect of the air diffused from the air diffusion device.
