Abstract: A ship IoT wireless communication system using metal surface waves is proposed. The ship IoT wireless communication system may include a first access point installed in a first compartment among a plurality of compartments formed in a ship, and a second access point installed in a second compartment among the plurality of compartments. Each of the first access point and the second access point may perform surface wave communication with each other to form a communication network inside the ship. Each of the first and second access points may include a surface wave generator configured to transmit and receive a surface wave through at least one of a floor, a ceiling, or a bulkhead of each of the plurality of compartments.

Abstract: The present invention relates to a method of scheduling for an underwater wireless mobile network. Particularly, the present invention relates to a method of scheduling for an underwater wireless mobile network, whereby the method may consider a scheduling method that does not cause collision at a specific time domain, and improve network efficiency by receiving in a sink node a packet in a packet train form in consideration with a transfer velocity of a sound wave and a packet length rather than performing orthogonalization to avoid transmission time overlap at a specific time.

Abstract: The present invention relates to a hydraulic height adjusting device for installing a heavy-weight structure to secure stable horizontal bearing power against a horizontal load of a heavy-weight upper structure. The present invention includes a lower frame which is installed on a top surface of the carrier and is provided with a plurality of receiving portions formed in an upwardly opened shape; and a hydraulic cylinder which is disposed in and engaged to the respective receiving portions of the lower frame, the hydraulic cylinder being moved in a vertical direction to adjust the height of the upper structure, in a state in which an upper end thereof supports the upper structure. The receiving portion is provided with a support guide which is interposed between an inner wall of the receiving portion and the hydraulic cylinder to annually enclose the hydraulic cylinder and thus prevent the hydraulic cylinder from being tilted.

Abstract: A method of automatically assigning IP in a ship ad-hoc network includes (A) receiving a non-duplicate IP block from a terrestrial station by transmitting/receiving an IP request signal and an IP request response signal generated from a data link layer by one-hop ship stations able to perform direct transmission/reception with the terrestrial station; (B) allowing the one-hop ship stations receiving IP blocks to determine IPs thereof and to allocate IP blocks, as IP providers, to multi-hop ship stations able to perform indirect transmission/reception with the terrestrial station through ad-hoc communication when the multi-hop ship stations request the IP blocks; and (C) determining one of the IP providers to transmit an IP request signal such that the determined IP provider transmits an IP request response signal when multi-hop ship stations, to which the IP blocks are not allocated, receive MAC frames of plural IP providers in a channel allocation.

Abstract: The present invention relates to a container search system comprising: a radiation irradiation unit for irradiating radiation to a container to be inspected; a detection unit installed opposite to the radiation irradiation unit to detect radiation having passed through a container; a transfer cart for loading an automobile thereon, on which a container to be inspected is loaded, and travelling along a search path formed between the radiation irradiation unit and the detection unit; and a circulation orbit unit formed to allow the transfer cart to circulate along the search path, wherein a primary side of a linear induction motor for generating a moving magnetic field is formed on either side among the transfer cart and the search path and a secondary-side reaction plate for inducing a secondary eddy current due to the moving magnetic field and generating a linear driving force is formed on the other side thereof. The container search system can transfer a transfer cart according to a linear motor scheme in a radiation search section, and thus can obtain a radiation search image of high quality.
