ROV Lightweight Lifting Tether System

A segmented marine tether that keeps a compact diameter for comms/power while adding a load-bearing lifting sleeve for safe launch/recovery, plus torsion control and optional “S-tether” buoyancy behavior. Enables lighter signal tethers to lift heavy ROVs safely: adds a load-bearing sleeve for in-air lift, reduces twist/hockling, and can form an “S” shape to lower tug on the vehicle.

Submersible Interferometric Sensor

This technology reads an interferometer signal using a standard spectrometer. It calculates absolute optical path length difference with very high precision, even when the spectrometer samples are not spaced in the usual “quadrature” way. It has a resolution from 1/1,000 to 1/100,000 of a wavelength, which supports high-precision sensing of parameters like refractive index, which can be used for salinity and density.

Beacon Deployment for Underwater Vehicles

Beacon Deployment for Underwater Vehicles is a payload release system for underwater vehicles and other platforms. It holds each payload by suction (vacuum), then releases it by letting water enter a chamber, and it supports passive weight compensation while a leg assembly helps the payload stand in a functional position.
