The growing use of unmanned surveillance "eyes in the sky" aircraft raises a thicket of privacy concerns, but the U.S. Congress is getting mixed advice on what, if anything, to do about it. A future with domestic drones may be inevitable. While civilian drone use is currently limited to government agencies and some public universities...
South Korea is analyzing whether projectiles North Korea fired into its eastern waters over the weekend are short-range missiles or a new type of artillery the country may be developing, officials said Monday. North Korea fired what Seoul officials called a short-range projectile Sunday, a day after conducting three similar launches.
These days, aerospace engineering is all about the light stuff: building airplanes with lighter wings, fuselage and landing gear in an effort to reduce fuel costs. Advanced carbon-fiber composites have been used in recent years to lighten planes’ loads. These materials can match aluminum and titanium in strength but at a fraction of the weight, and can be found in aircraft like the Boeing 787 and Airbus A380, reducing such jets’ weigh...
Counterfeiters are adaptable and constantly incorporating solutions that can void the latest countermeasures adopted by the electronics manufacturers and their supply chain. In some cases, the counterfeits are very hard to differentiate from the original component.
Commercial and military aircraft manufacturers are promoting the replacement of older hydraulic and pneumatic control systems by lighter and more efficient, electrically-driven systems through a trend known as MEA, or More Electric Aircraft.
An electrolytic capacitor has two electrodes, one with a dielectric, that relies on electrostatic charge storage. A battery has electrodes that store energy faradaically in electrochemical reactions involving the electrodes and electrolyte. A hybrid capacitor is the combination of two electrodes, one that stores charge electrostatically, and the other storing charge faradaically.
M/A-COM Technology Solutions introduced a series of GaN in Plastic packaged power transistors for high-performance civilian and military radar and communications systems. The family scales to peak pulse power levels of 100 W, which is asserted to be the
Oven Industries is now offering a high-powered temperature controller mounted on a heat sink that creates a seamless transition between heating and cooling devices, as it serves as the commander of thermoelectric modules. With a bi-directional or unidirectional H-bridge configuration, the controller has many benefits.
A revised version of David Bowie's Space Oddity, recorded by Commander Chris Hadfield onboard the International Space Station. This is believed to be the first music video recorded in space (and as Internet memes go, it sure beats silly cat videos). Captioning kindly provided by CHS (www.chs.ca)
Highland Technology announces the release of the V120 VME PCI Express Crate Controller for aerospace, industrial, and laboratory application. The V120 is a VME bus master crate controller, usable as a crate slot 0 arbiter or as a secondary controller. Each PCI Express cable driver board, in a PC backplane, can drive one or two V120s over standard, flexible PCI Express cable assemblies....
The Boeing X-51A WaveRider unmanned hypersonic vehicle has achieved the longest air-breathing, scramjet-powered hypersonic flight in history. Last summer, an infestation took control of the Harvard robotics laboratory. The situation posed no need to call an exterminator, for this demonstration featured the first controlled flight of an insect-sized robot inspired by the biology of a fly.
Researchers at the U.S. Naval Research Laboratory flew their fuel cell powered Ion Tiger UAV for 48 hours and 1 minute on April 16-18 by using liquid hydrogen fuel in a new, NRL-developed, cryogenic fuel storage tank and delivery system. This flight shatters their previous record of 26 hours and 2 minutes set in 2009 using the same vehicle...
Kontron announced the ready-to-use SMARC Starterkit. The kit offers developers fast entry into the world of embedded ARM processors, which is now highly scalable owing to SMARC Computer-on-Modules. The kit comes in a sturdy transport case, has all the cables already connected and is
A U.K. budget airline will create an artificial volcanic ash cloud over Europe this summer to test ash detection technology. The experiment aims to avoid the kind of chaos that paralyzed air traffic during eruptions three years ago. Thursday's announcement was made by easyJet....
Skyworks Solutions introduced a surface mount limiter diode for receiver protection applications. The CLA4608-085LF is a low capacitance silicon PIN limiter diode designed for high power applications ranging from 10 MHz to over 6 GHz. The maximum resistance at
Coilcraft CPS (Critical Products and Services Group) has released its AT392RAS inductors, targeting applications where high temperatures can be encountered. Air-core design and special materials allow operation in ambient temperatures as low as –60°C and up to 240°C. Five inductance values are
Alone in the single-seat cockpit and high above the American Southwest, pilot Bertrand Piccard could hear only his plane's gear box and the quiet whine of four electric motors. No noisy jet engines. He's flying Solar Impulse, considered the world's most advanced sun-powered plane.
An experimental, unmanned aircraft developed for the U.S. Air Force went hypersonic during a test off the Southern California coast, traveling at more than 3,000 mph, the Air Force said Friday. The X-51A WaveRider flew for more than three minutes under power from its exotic scramjet engine and hit a speed of Mach 5.1, or more than five times the speed of sound.
Samsung Electronics Co. says the U.S. Department of Defense has approved using Samsung smartphones for its networks. The South Korean company said Friday the Galaxy S4 smartphone has become the first Android device to meet the security requirements set out by the U.S. government...
With 160 confirmed kills, Chris Kyle is one of the most prolific snipers in American history. The best-selling author of American Sniper was recently killed on a shooting range by a fellow vet, and Kyle's wife graciously donated his sniper rifle to NVision for them to scan for a project.
Determined to kill or capture a murderous Mekong River drug lord, China's security forces considered a tactic they'd never tried before: calling a drone strike on his remote hideaway deep in the hills of Myanmar. New light has been cast on China's unmanned aerial vehicle program, which has been quietly percolating for years and now appears to be moving into overdrive.
NASA's newest scientific rover is set for testing May 3 through June 8 in the highest part of Greenland. The robot known as GROVER, which stands for both Greenland Rover and Goddard Remotely Operated Vehicle for Exploration and Research, will roam the frigid landscape collecting measurements...
Cal Sensors announced an optical detector technology capable of detecting muzzle flash from over 100 meters away, while minimizing false alarms. Operating at the speed of light, an optical flash detection system provides an almost instantaneous response to a gunfire event, providing
Data Device Corporation (DDC) introduced the AceXtreme Bridge Device to translate avionics messages in real-time between MIL-STD-1553, ARINC 429, and Ethernet in any direction, without a host computer. With an onboard Intel Atom processor, two Ethernet channels, two
NVision recently volunteered its 3D laser-scanning services to help Sarasota sculptor Greg Marra create an exact replica of the rifle that former Navy Seal Chris Kyle used while in the military. Christopher Scott “Chris” Kyle is widely considered to have been the most lethal sniper in U.S. military history with over 150 confirmed kills.
