The same tomography/thermometry network of acoustic sources and receivers can also provide long-term passive acoustic listening, underwater acoustic navigation (performing a global positioning system [GPS] function underwater), and low bandwidth communications providing the navigation and timing required for under-ice operation of autonomous gliders, floats, and unmanned undersea vehicles (UUVs) in the Arctic (Fig.
Acoustic networks can improve observations of the water column beneath the ice directly, using tomographic/thermometry measurements, while simultaneously providing acoustic navigation and communications supporting autonomous vehicles.
The AITPs are currently equipped with 1560 Hz and 780 Hz sound sources to provide acoustic navigation of and communication with gliders and floats operating under ice.
The acoustic transceivers also transmitted RAFOS signals to provide an underwater acoustic navigation system for gliders and floats.
Robert Mehrabian, chairman, president and chief executive officer of Teledyne, says that through CDL and its other marine instrumentation companies, Teledyne provides surface and subsea inertial measurement and motion sensing solutions based on a number of different technologies including mechanical, ring laser and fibre optic gyrocompasses and dynamic motion sensors, as well as acoustic navigation
Yi-Xian Qin, Director of the Orthopaedic Bioengineering Research Laboratory at Stony Brook University, has revealed that the new technology, called Scanning Confocal Acoustic Navigation
(SCAN), works by assessing multiple parameters of hard tissue like bone.
Let go of the latch, and, using an acoustic navigation
system to guide its movements, travel around its survey area taking video snap shots and making a variety of measurements.
Proclude[R], the Sonic Fracture Healing System (SAFHS)[TM], the V3D Colon[TM] virtual colonoscopy, Emulsiphan(TM), the Scanning Confocal Acoustic Navigation
(SCAN)[TM] system, Vita-Assays[TM], and the Dynamic Motion Therapy (DMT)[TM] platform are just a few of the innovations that have resulted from our activities.
