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.

An underwater communication method includes creating an air column in a water body using a device including a device body, an air column-generating component, and a transceiver, thereby forming an air column to a surface of the water body. A signal is transmitted, received, or a combination of transmitted and received using the transceiver through the air column to the surface of the water body.

A computer implemented method and apparatus for a marine vessel data system, the method comprising: receiving data from at least one sensor configured to measure vibration and operationally arranged to the marine vessel to provide time-domain reference sensor data; maintaining the time-domain reference sensor data within a data storage system; generating a Fast Fourier Transform (FFT) on the time-domain reference sensor data to provide a plurality of reference spectra files in frequency-domain, wherein each reference spectra file comprises spectra data defined by amplitude information and frequency information, and each spectra file is associated with condition information determined based on collection of the time-domain reference sensor data; normalizing each reference spectra file by converting the frequency information to order information using the condition information to provide normalized reference spectra files; and training a convolutional autoencoder type of neural network using the normalized reference spectra files.

A marine-type communication device that reads data from a data bus, dynamically creates new data channels for a plurality of operational systems and performs a volatility assessment to determine when to save the data for transmission to a cloud network and when to transmit the data to the cloud network.

The system for an antenna assembly for use on unmanned underwater vehicles (UUV). The antennas are low-cost, lightweight, single-use, and have a small form factor amenable to use on a micro-UUV. A central post and pivotally attached arms form an antenna (e.g., a monopole) that is lifted via an aerial, kite, or the like, when deployed from the UUV to extend the line of site of the antenna several meters above the surface of the water. In some cases, the antenna may be used on a number of UUVs in a swarm formation.

The instant invention describes devices and methods of measuring the differential air pressure at numerous representative points across the surface of the sail and providing visual feedback of areas of ideal laminar flow and areas of less than optimal airflow with an indication of how the sail must be adjusted to create the maximal differential in airflow. The invention utilizes an array of sensors that detect minute variations in barometric pressure and other data on each side of the sail surface. These sensors are connected together to form a network or net across the sail. This connection can be physical, using wires, or it may be wireless, using for example, but certainly not being limited to, Bluetooth LE 5.0 or other wireless topologies or technologies. Finally it may utilize a combination of wired and wireless connections to fit individual situations and may couple with existing terrestrial and satellite ship networks.

Methods and systems enabling electronic devices associated with each of at least two watercrafts to dynamically form ad hoc wireless networks when the corresponding watercrafts are within range of one another are provided. Data transfer on the water is thus enhanced via such ad hoc mesh-type networks. A method of distributing marine electronics data includes receiving, over a first wireless local area network at an electronic device associated with a first watercraft, marine electronics data from an electronic device associated with a second watercraft; establishing a second wireless local area network between the electronic device associated with the first watercraft and an electronic device associated with a third watercraft; and transmitting the marine electronics data received from the electronic device associated with the second watercraft from the electronic device associated with the first watercraft to the electronic device associated with the third watercraft over the second wireless local area network.

An axial piercing mechanism for a pressurized gas canister includes a housing, electric motor assembly, pushrod assembly, and lancet. The housing defines one or more radial exhaust ports and coaxial internal cavities. The electric motor assembly and pushrod assembly are disposed in the respective first and second cavities. The pushrod assembly is coupled to the electric motor assembly and is rotatably driven along the longitudinal axis thereby. The lancet is coupled to the pushrod assembly. The housing includes a second end that receives or couples to a sealed end of the pressurized gas canister proximate the lancet such that the electric motor assembly, when energized, causes the pushrod assembly and lancet to translate along the longitudinal axis, pierce a sealed end/diaphragm of the canister, and release pressurized gas through the exhaust port. A system includes the axial piercing mechanism and the pressurized gas canister.

A system and method for optical communication between multiple UUVs, more specifically, for leader-follower formations between UUVs. The system focuses on the characterization and modeling of a 1-dimensional and/or 3-dimensional light field produced from a light source mounted on a Leader UUV, which is detected by one or more follower UUVs. Communication algorithms are used to monitor the UUV's motion and orientation utilizing simulators, look up tables, and the like. A variety of detectors arrays can be used in a variety of wavelengths depending on the desired application.
