A quickly deployable and reconfigurable light emitting diode (LED) lighting apparatus with high output intensity and precisely controlled beam property is disclosed for navigational aids. The lighting apparatus comprises an array of high intensity LED units with their light beams individually controlled by secondary optical systems. The transformed light beams mix in a pre-determined manner to produce an illumination pattern with desired intensity distribution. The LED lighting apparatus may further comprise a micro-controller, a plurality of sensor elements, and a wireless transceiver for remote monitoring and control. The lighting apparatus can be powered by rechargeable batteries for temporary or semi-permanent lighting. It can also be powered by standard power lines for permanent lighting.

A lighting device having a plurality of LEDs mounted on a heat sink that serves to transfer heat from the LEDs to the outside environment. The lighting device is positioned within a fresnel lens to produce a distribution of light.

A lamp assembly adapted for underwater use including a guard tube adapted for being filled with water and for forming a hollow housing for the lamp assembly and an inner tube positioned within the guard tube to provide a waterproof environment for the lamp assembly.

A lighting device having a dual LED point-source assembly containing two high flux LEDs mounted facing each other with LED lenses positioned between the LEDs. At least one heat sink is attached to one of the LEDs. The heat sinks serve to transfer heat from the LEDs to the outside environment. In one embodiment the lighting device is positioned within a fresnel lens to produce a horizontally uniform distribution of light.

In one aspect, a control mechanism for a trolling device has an interface for establishing a network connection between the control mechanism and an electronic GPS mapping computer having an electronic display for displaying data. In an aspect, the control mechanism is configured to receive control instructions from the electronic GPS mapping computer to execute speed or direction.

The present invention relates to a passenger ship navigation management system using AIS two-way communication, and a control method thereof. The passenger ship navigation management system comprises the following components: a control center which receives real-time AIS position information from a plurality of wireless base stations for analyzing a port entering and leaving state of a passenger ship and notifying the current ship navigation state to a passenger ship navigation control center; and the ship navigation control center which is administrated by the port and comprises the following components: a seacoast wireless base station device which transmits the land information that is supplied from the control center to an on-sea terminal, and receives the position information transmitted from the on-sea terminal to the control center; a passenger ship monitor device which is connected with the control center and displays the state of the inward-outward passenger ship on an electronic navigational chart for monitoring the position of the passenger ship in sea navigation, while the passenger ship navigation control center provides information; and an on-sea passenger ship terminal which receives and displays a sea navigation support function with the electronic navigational chart and the on-sea security support short message transmitted from the land, and furthermore transmits the position of the terminal and the ship navigation information to the land.

A subsea vertical glider robot which supports deployment in subsea oilfield activities is disclosed. This vertical glider robot can also be used in oceanographic research exploration. One application of this vertical glider robot is the autonomous delivery of equipment and sensor systems to a precise predetermined location on the sea floor. The vertical glider robot is deployed from a surface ship or any other suitable sea surface platform and allowed to free fall to the bottom of the ocean. The traversal through the body of water is performed primarily by converting initial potential energy of the apparatus into kinetic energy, it does not use propellers. The traversing of the seafloor is controlled with a steering module that refines orientation while processing information about the vertical glider robot's current position and the target where it has to land.

The invention relates to a navigation mark capable of generating electricity with wave energy. The navigation mark comprises a fixed column, which is fixed on the riverbed or seabed, with the top extending out of the water level and a sliding block sleeving the fixed column, wherein two buoys capable of bobbing up and down around a hinge point are hinged to two sides of the sliding block respectively, two arc racks are fixed on two sides of the sliding block respectively, the fixed column is provided with a straight-line rack, the sliding block is provided with a first electric generator and a first gear mechanism, an input shaft of the first electric generator is engaged with the straight-line rack permanently through the first gear mechanism, each buoy is provided with a second electric generator and a second gear mechanism, and an input shaft of the second electric generator is engaged with the arc rack permanently through the second gear mechanism. The navigation mark is capable of generating electricity with wave energy, simple in structure and not easy to damage.

A system comprising a radar subsystem including a radar transmitter and a radar receiver, and an encoder subsystem including a computer connected to a transmitter and two antennas. The computer is configured to encode and transmit a custom payload AIS Type 8 message. A second computer connected to a receiver and antenna receives the message. The custom payload AIS Type 8 message contains target longitude, latitude fields, range, and bearing fields.A method for transmitting and receiving the radar track of a target ship including: receiving the radar signal at the own ship; encoding the target ship longitude, latitude, speed, and course into a custom payload AIS Type 8 message; transmitting the custom message to a receiver ship; decoding and displaying the target ship longitude, latitude, course, and speed at the receiver ship.
