Fiber Optic Rotary Joints Add a Spin to Sensing, Mobile, and Robotic Fiber Systems

To the passing optical signals, fiberoptic rotary joints (FORJs) are nothing more than fiber connectors, which provide connection between one or multiple fibers. Their unrestricted ability to rotate, however, gives them a critical role in many sensing, mobile, and robotic fiber systems such as ROVs (remotely operated vehicles), aerostat radars, submarines, satellite antennae, OCT (optical coherence tomography), mining vehicles, cranes, wind turbines, robotic vehicles, broadcasting (mobile cameras), etc. This article discusses some of the applications where optical rotary joints are indispensable. www.princetel.com

Unmanned Naval Helicopter

Northrop Grumman Corporation Redondo Beach, CA 310-812-4321 www.northropgrumman.com The U.S. Navy has been conducting ship-board flight testing of the first operational MQ-8C Fire Scout unmanned helicopter delivered by the Northrop Grumman Corporation. After more than a year of land-based testing conducted at Point Mugu, California, the MQ-8C took its first flight off the deck of the guided-missile destroyer, USS Jason Dunham (DDG 109), off the coast of Virginia in mid-December last year. It marked the first time an unmanned helicopter had ever operated from the deck of a U.S. Navy destroyer. All told, the new Fire Scout made 22 takeoffs and precision landings during its first sea trials, all while being controlled from the ship’s ground control station. According to George Vardoulakis, Northrop Grumman’s vice president for medium range tactical systems, the test program will run throughout the summer of 2015 and if all goes well, the aircraft should be operational by the end of the year.

Anti-Hacking Software for UAVs

Galois Portland, OR 503-626-6616 http://galois.com To address growing evidence that commercial Unmanned Aerial Vehicles (UAV), automobiles and other vehicles are vulnerable to hacking and sophisticated cyber security attacks, Galois developed and successfully demonstrated what has been called “the world’s most secure UAV software.” Galois, a company that specializes in protecting information, devices, networks, and vehicles, recently conducted a successful demonstration for the U.S. Defense Advanced Research Projects Agency’s High-Assurance Cyber Military Systems (HACMS) program. Galois is part of a team that produced provably correct and secure software that runs on commercial UAVs.
