Kraken Delivers Real Time Sonar Signal Processor

.   In 2013 DSTO procured an AquaPix Interferometric Synthetic Aperture Sonar system from Kraken for research related to enhancing mine detection and neutralization techniques using Autonomous Underwater Vehicles (AUVs). As their research advanced, DSTO scientists required a real-time sonar signal processing capability embedded directly onboard their REMUS 600 AUV. In real-time signal processing, the analyzed (input) and generated (output) samples can be processed continuously. DSTO is also developing automatic target recognition algorithms to identify naval mines. Moving the algorithms directly

New All-in-one Optical Incremental Encoder from Renishaw

Available to order from August 2016, VIONiCplus is Renishaw's new optical incremental encoder system launched as part of the VIONiC digital all-in-one encoder series. The VIONiC design combines all necessary interpolation and signal processing inside the readhead and eliminates the requirement for additional external interfaces. To this end, Renishaw said it has developed a new Versatile Interpolation ASIC (VIA) chip to perform all of the functions originally executed by the interface. Other features, working in conjunction with the Advanced Diagnostic Tool (ADT), bring the end-user wide-ranging

ASL Builds Custom Instrument for Hydrothermal Vent Flow

NEPTUNE cabled observatory at the Endeavour hydrothermal vent site, approximately 300 kilometers off the west coast of Vancouver Island, in 2,200-meter water depth. The deployment is scheduled for 2016, with logistical support from Ocean Networks Canada.  The instrument will employ advanced signal processing techniques and two-way acoustic transmissions to measure the rise velocity of the plume and its turbulent properties in near-real time. Long-term measurements of these properties, in conjunction with three-dimensional plume models, will advance understanding of the interaction between hydrothermal

The HeliCom Matrix achieves superior, crystal-clear diver helium voice communication through advanced DSP (digital signal processing) helium speech decoding techniques. The helium speech from the pressurised divers and the chamber occupants are mixed in an audio mixer before decoding to the selected gas and environmental settings by a digital signal processing circuit (DSP). This has been the key element of HeliCom&rsquo

bandwidth and transmission rates. EvoLogics underwater acoustic modems and positioning systems continuously spread the signal energy over a wide range of frequencies and adapt the signal structure so that the multipath components do not interfere with each other. At the receiver end, advanced signal processing collects the energy and converts the received signals into sharp signals. This results in achieving significant depression of multipath disturbances and substantial system gain, enabling successful decoding of signals also in challenging environments.
