DSIAC collects and publishes articles related to our technical focus areas on the web to share with the DoD community.
Physiological mechano-acoustic signals, often with frequencies and intensities that are beyond those associated with the audible range, provide information of great clinical utility. Stethoscopes and digital accelerometers in conventional packages can capture some relevant data, but neither is suitable for use in a continuous, wearable mode, and both have shortcomings associated with mechanical transduction of
Bell Helicopter is taking its legacy developing tiltrotor technology into the unmanned world with a new aircraft it is calling the V-247 “Vigilant.” The company unveiled a model of the aircraft Thursday at the National Press Club in Washington, complete with a motorized demonstration of how the unmanned aircraft system can fold its wings and
Energetic materials and munitions are used across DoD in mission critical applications such as rockets, missiles, ammunition, and pyrotechnic devices. In these applications, energetic materials and munitions must perform as designed to ensure success in both training and combat operations. There are, however, potential environmental, occupational safety and health risks associated with these materials. Mitigating
Piezoelectric sensors measure changes in pressure, acceleration, temperature, strain or force and are used in a vast array of devices important to everyday life. However, these sensors often can be limited by the “white noise” they detect that can give engineers and health care workers false readings. Now, a University of Missouri College of Engineering
High tech for low casualties. A gun is a powerful tool for putting a hole in a person. That power made them a staple of armies centuries ago and keeps them on the hips of soldiers, law enforcement, and Gadsden-flag-wearing anybodies to this day. Among the problems of such a lethal tool is that, in
Researchers at the U.S. Naval Research Laboratory (NRL), Optical Sciences Division, in collaboration with the laboratory’s Material Science Division, for the first time have demonstrated successful detection of acoustic emission from cracks in riveted lap joints using a distributed feedback fiber laser-acoustic emission sensor. “An automated, in-situ structural health monitoring (SHM) system, capable of monitoring
Hundreds of military, government and commercial satellites reside today in geosynchronous Earth orbit (GEO) some 22,000 miles (36,000 kilometers) above the Earth—a perch ideal for providing communications, meteorology and national security services, but one so remote as to preclude inspection and diagnosis of malfunctioning components, much less upgrades or repairs. Even fully functional satellites sometimes
Thales is unveiling its AUSS concept (Autonomous Underwater & Surface System) long-range hybrid multi-mission multi-sensors remote-controlled system capable of operating both above and below the surface. The new naval system was designed for a broad range of military roles including surface intelligence gathering such as ELINT (Electronic Intelligence), IMINT (Imagery Intelligence ), COMINT (Communications Intelligence)
This month the U.S. Army”s Army Expeditionary Warrior Experiments (AEWE) program tested the AimLock Stabilized Weapon Platform for the first time during a live fire exercise. This ungainly-looking gun seeks to revolutionize the average infantryman”s combat effectiveness by removing human error from the equation entirely. A civilian development company called Rocky Mountain Scientific Laboratory (RMSL),
A new collaborative effort that connects Navy technical experts with academia is helping to create partnerships that generate real innovation. As a catalyst for developing the Navy’s future workforce, professors and students at universities nationwide are conducting research and development on naval-relevant topics at their campus laboratories. The research takes place through the Naval Engineering
The Army is putting the finishing touches on its robotics and autonomous systems strategy, according to the director of the Army Capabilities Integration Center. The strategy, expected to come out this year, is in “the final stages of editing now,” Lt. Gen. H.R. McMaster told Defense News in an interview at the Association of the
Scalable laser weapon system brings down UAVs in all weathers, showing promise for military deployment, Defense systems company MBDA Deutschland has reported successful testing of a new high-energy laser effector – a key element in a laser-based weapons system – at a military training facility on Germany’s North Sea coast. The company says the tests,
