payload, running at peak efficiency gives the micro-UUV a range of a little more than 100 nautical miles in 33 hours. This presumed an operating speed of 3.0 knots. At 0.5 knots the same vehicle configuration could run for three days.In early 2018, Riptide announced a near-total redesign of internal electronics resulting in a new MKII µUUV. This offered a nearly 60% reduction in hotel load power to 3.8 Watts from its first-generation boards. It also reduced the internal wire count in the vehicle by 80%, simplifying the vehicle further. This traditional battery based performance is more than adequate

An inevitable outcome from this will be the spin-off technologies that develop into new economic opportunities, such as cheap 3D-printed casing for electronics that can withstand up to 5,600 lbs. per square inch of pressure.Primarily through private industry, a race is currently underway and focused on four kilometers below the ocean’s surface. Today, teams are letting robots do the work of aquanauts with artificial intelligence and virtual reality

and asset longevity. Avitas Systems will be able to complete subsea inspection with reduced cost and time, and operational footprint.   Kraken Robotics brings a broad range of cost efficient AUV technologies, such as underwater sensors, pressure tolerant batteries, thrusters and control electronics. Avitas Systems will integrate these technologies into an autonomous subsea inspection system. The data from this inspection will be uploaded into a state-of-the-art platform that includes robust data ingestion, automatic defect recognition, predictive analytics and a cloud-based visualization

New Owner Takes Over at WESMAR

Bruce H. Blakey, founder and President of WESMAR (Western Marine Electronics), has sold his company to local businessman Roger Fellows, effective November 1, 2017.   Blakey has sold the company to a new innovator whom he says is poised to take the company and its products to new heights. The name of the company will remain the same. Headquarter operations will remain in Woodinville, Wash. and employees will remain with the company, says its new owner and president Fellows.   “WESMAR is impressive,” Fellows said. “It is not every day someone can purchase a company with

Nortek analyzed the noise spectrum present at the site and was able to modify the internal filter of the power supply to reduce the EMC noise and enable the 20-meter range.  “There are subtle electronics in the ADCP instrument, and the turbine itself is basically a giant electromagnet. This meant that initially, we couldn’t get any useful data so close to the turbines. There is also a lot of fluctuation and turbulence in the water. To measure that properly you need to measure quickly and

Teledyne has recently qualified three new configurations that extends the range of the CAN bus signal to up to 5,000 meters. The Active Flying Lead product line is characterized by integrating specialized electronics into qualified highly reliable atmospheric housings located directly within a subsea cable, or flying lead. The ability to run CAN Bus signals longer than before allows for greater flexibility in the placement of sensors in an oil field or subsea observatory. The alternative is to locate a control

M&SS is a pretty broad, large, and steeped in the traditional maritime business that has been on a strong and sustainable growth curve for 20 plus years. Basically we do electronics – especially mission systems – system integration, and product development for many maritime programs. And then the word “strategic” that’s in that acronym, as well, “strategic” meaning “nuclear” so think Navy nuclear. I have four businesses

reliable over multiple mating cycles since there are no dynamic seals that wear out, a far more forgiving mating tolerance, immunity to contamination and no pins to align, break or bend. A reduced mechanical complexity is valuable in increasing reliability, and justifies the application of solid-state electronics. There are further enhancements that an intelligent connector can provide which ‘simple’ pins cannot, such as localized network diagnostics.”   One of the vital breakthroughs that made the UAC concept viable relates to WiSub’s patented high-speed, high frequency
