Counter-Drone Technology

Citadel Defense
San Diego, CA

Citadel Defense has developed a Counter-drone (CUAS) technology called Titan that reliably detects, identifies, and defeats unmanned aerial vehicles (UAV's or “drones”) and swarms threatening combat troops, critical infrastructure, or information espionage. The company recently manufactured a first-of-its-kind solution designed to protect troops, vehicles, and permanent structures from threat drones.

Video Graphics Modules

WOLF Advanced Technology
Stouffville, Ontario, Canada

WOLF Advanced Technology (“WOLF”) recently announced that NASA has chosen two WOLF video graphics modules to take part in the development of NASA's X-59 Quiet SuperSonic Technology (QueSST) aircraft. Now under construction by Lockheed Martin Aeronautics Company at its famed Skunk Works plant in Palmdale, California, the X-59 is designed to reduce the noise generated by a sonic boom. Once fully tested and pronounced safe to fly within the National Airspace, the X-59 in late 2022 will begin making supersonic flights over select communities to measure residents’ reactions to any noise they might hear.

Electrical Characterization of Crystalline UO2, THO2 and U0.71TH0.29O2

Tracking and identifying radiation sources in the age of nuclear proliferation and well- resourced non-state actors is a national priority. Current neutron detection methods favor large detector volumes and long data collection times. Additionally, portable neutron detection methods have persistent problems with low signal-to-noise (small pulse height) and require large applied voltages.

Matrix-Free Assisted Laser Desorption Ionization Using Metal-Organic Frameworks

Matrix-assisted laser desorption/ionization (MALDI) is a soft ionization technique that is widely applied in the characterization of large biomolecules using various mass spectrometry (MS) analyzers, specifically, time-of-flight (TOF) analyzers. The MALDI process involves the deposition of an analyte solution onto a metal substrate before the addition of a matrix. The matrix/analyte dry spot is exposed to a UV laser, and the laser energy that is absorbed by the matrix/analyte is converted into heat energy that initiates charge transfer, which results in the desorption of the matrix and analyte molecules in ionized form. The positive ions are then accelerated through a vacuum into MS analyses.

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.

Hydraulic Propulsion an Alternative to Drone Batteries

Drones require heavy batteries or lots of electrical components, which leaves little room for the actual payload. A Purdue University team came up with a method to use fluid power technology for autonomous vertical takeoff and landing (VTOL) vehicles.

US and Japanese Scientists Conduct Joint Composites Study

Dr. Keisuke Umezawa of the Air Systems Research Center in the Japanese Ministry of Defense (JMoD) recently joined the Air Force Research Laboratory on an engineers and scientists exchange program (ESEP). The JMoD chose Umezawa for the ESEP based on his experience as a stress analysist of polymer matrix composite materials. Also, Umezawa has been heavily involved in the development of the next generation Japanese fighter aircraft, including the development of the test program for prototype PMC structures.
