[ARCHIVED] NUWC Division Newport Inventors Showcase Cutting-Edge Technology During Collaborative Event At URI

NUWC Division Newport inventors showcase cutting-edge technology during collaborative event at URI

Three Naval Undersea Warfare Center (NUWC) Division Newport technologists shared information on undersea warfare-inspired inventions during the Technology Commercialization, Research and Development Showcase held Dec. 6 at the University of Rhode Island (URI).

A number of dignitaries — including U.S. Sens. Jack Reed and Sheldon Whitehouse (both D-RI) and URI President Marc Parlange — and members of the 401 Tech Bridge, URI, industry and R.I. 

Commerce community received presentations about exciting new technologies that have a broad range of potential commercial applications.

“We are poised for success because of this collaboration. Collaboration, the exchange of ideas, is what is going to move us forward and we have to do it faster,” Reed said. “NUWC, as we all recognize, is the national leader in developing underwater systems. Submarines provide that cautionary note to our adversaries wondering what they’re doing and where they are. 

“China is the pacing threat and when you turn to the Pacific, there’s a lot of water out there. We have to develop very, very quickly because we’re up against a very sophisticated, agile competitor.”

Dr. Tariq Manzur of Division Newport’s Undersea Warfare (USW) Electromagnetic Department, Paul Cavallaro of the Ranges, Engineering and Analysis Department, and Bill Craig, technical project manager for advanced technology in the USW Electromagnetic Department — filling in on behalf of inventor Dr. David Tonn — first gave an overall presentation on these new technologies and later provided opportunities for one-on-one discussions with attendees during a poster session.

Manzur’s presentation focused on photonics and laser technology, Cavallaro discussed advances in the field of composites and fabrics, and Craig briefed on breakthroughs with antennas. The event also included tours of URI’s cutting-edge Research CORE Facilities and Dynamic Photo-Mechanics Laboratory in Fascitelli Center for Advanced Engineering located on the Kingston campus.

“I’m very proud of NUWC; it’s a great organization,” Reed said. “It’s an engine for our efforts to accelerate sophisticated new technologies and get them into the fleet.”

Mary Sylvia, head of the Technology Partnerships Office, and Jim Kasischke, supervisory patent counsel, Office of Legal Counsel, also discussed the technology transfer process with an emphasis on the merits of patent licensing, while Chief Technology Officer Jason Gomez gave an overview of the entire program.

Gomez noted that a recent government study revealed Division Newport has generated almost 800 patents in the past 30 years. This represents 10% of the total number of patents awarded to the Department of the Navy (DON) over that period of time despite Division representing less than 2% of the total civilian Navy’s workforce.

“NUWC’s been there for a long, long time. We have a great relationship with URI and a growing relationship with the Tech Bridge,” Gomez said. “Throughout its 152-year history, NUWC has put a lot of emphasis on capturing intellectual property and we’re really trying to grow an innovative culture at NUWC. 

“While we need to protect our intellectual property, we also recognize the advantage of sharing it with the communities we work with to increase the speed of development for both fleet capability and commercialization.” 

Specifically, Manzur’s inventions focus on photonics technology of an optical amplifier, light detection and ranging (LiDAR), free space multi-frequency stealth laser communications and innovative optical amplifier pumping schemes. Manzur offered a handful of potential commercial applications for this technology, including auto-driving, commercial ship navigation and satellite communications or tracking.

Cavallaro, meanwhile, presented two technologies: Inflatable structures and experimental test fixtures, as well as crimp imbalanced fabrics for improved fragment and projectile impact protection. 

The inflatable project, Cavallaro explained, was a spinoff of another project where the Department of Defense (DOD) needed to repatriate the remains of soldiers killed in action by chemical or biological means.  

“These aren’t pool toys or the waving inflatable arm guys that we’re talking about here. Imagine something you could take out of your pocket and it inflates to 100 times its original size,” Cavallaro said. “With inflatable structures constructed from high-performance fibers, you get out of it what you put into it. What you put into it is the inflation pressure, which can be air, water or gas. The more you put in, the more pressure you generate and the higher the load-carrying capacity. You also get the unique benefit of elastic fail-safe recovery modes of operation during an overloading event.”

This technology has a number of applications, such as inflatable launch and recovery systems for underwater towed bodies, inflatable fendering systems for marine vessels or hazardous materials, or bulk material transfer packages for use in severe environments. 

“Ultimately, we’re taking it into the next level as composites and inflatables dovetail right into soft robotics for undersea launch and recovery,” Cavallaro said. “The State of Rhode Island is geared heavily in the textiles market. We believe there’s a lot of transition opportunities.”

The crimp imbalance fabric is one of those opportunities. A simple architectural modification during the weaving process yields a fabric that can enhance the dynamic impact protection levels in soft body armors. This process provides not only more protection to warfighters and law enforcement officers, but more comfort and mobility at a lighter weight. 

Craig, presenting some of Tonn’s inventions, closed the Division Newport technology discussions with a talk on a patch antenna retrofit kit and broadband linear antennas.

“Dave [Tonn] is really an exceptional engineer and inventor. He and I have worked together for almost 30 years,” Craig said. “We got into a routine where he’d come up with an idea and say, ‘What if we did this? What could we do with that effect?’ Then we’d go from there.”

Craig explained how the retrofit kit is not only cost-effective and easy to install on existing antennas, but also improves capability as it can significantly increase bandwidth depending on the specifics of the antenna.

The broadband linear antenna, meanwhile, improves the bandwidth of linearly polarized antennas such as monopoles and slotted antennas to the point that they can support several communications functions in a single antenna. The potential commercial applications of these technologies are wide-reaching given the reliance on antennas in so many fields.
