Weight, hinge design, and assistive power of a quasi-passive exoskeleton were studied at the U.S. Army Natick Soldier Research, Development and Engineering Center here to see how these factors affect the way an individual walks. The study, done in conjunction with Yale University, also measured how much energy a person used walking with the knee brace.
Unmanned aerial vehicle pilots maintain an "eye-in-the-sky" view providing real-time surveillance high above the battlefield in order to keep Soldiers safe from unexpected "enemy" attacks, at the U.S. Army National Training Center, here. Before putting Soldiers in harm's way, military unmanned aerial vehicles, known as UAVs, perform aerial reconnaissance, be it night or day.
In the great world of 3D printing, nothing is more fascinating to me than the idea of printed food. There has been some rumblings about printed meat, but it’s been mostly outliers in the industry. However, NASA just made it a little more legitimate with by offering a $125,000 grant to Systems and Materials Research Corp to develop a 3D printed version of an American (and worldwide) favorite: Pizza.
VPT Inc., a HEICO company, announced the availability of a new series of radiation hardened DC-DC power converters, point of load converters, and EMI filters to power space systems.
A solar-powered plane is flying from Arizona to Texas on the second leg of a trip across the United States. The Solar Impulse is making the first attempt by a solar airplane capable of flying day and night without fuel to fly across the U.S.
What steps are necessary to keep counterfeit components out of the supply chain? Are more industry standards needed? Stop having unrealistic pricing expectations. Understand and qualify quality vendors of all kinds. Allocations and obsolescence are part of our industry....
Imagine trying to solve this complex problem: You have to modernize a fleet of combat vehicles, such as tanks, tracked howitzers and infantry fighting vehicles, choosing from among more than 50 ways to update them to meet future threats. Each modernization option can be configured differently to meet a variety of missions around the globe.
Sometime in the next quarter-century, NASA plans to send the first humans to Mars, a mission that will push the boundaries of teamwork for a handful of astronauts who will spend as long as three years together in a tiny capsule. A Michigan State University project, now wrapping up its third year, aims to arm the crew....
Think keeping in shape is an uphill battle? Try staying fit in space, where living quarters are cramped and prolonged weightlessness withers muscle and bone. That's the challenge a group of Michigan State University researchers will address with a new three-year, $1.2 million grant from NASA.
Chris Hadfield might just be the coolest guy on the internet (or in this solar system.) The astronaut—who just recently returned to earth—made it part of his mission to share different things happening on the international space station since he took command—the first Canadian to do so—on December 19, 2012.
Wireless and wired technologies have advanced to the point where automated control systems are routinely networked together. Information can be shared and tasks performed across long distances, via the Internet, linking systems in large industrial spaces, or across remote or rugged areas. Networked control systems (NCS) offer many benefits such as far greater efficiency than manual controls....
M/A-COM Technology Solutions announced a new broadband Flip Chip Schottky Diode for multi-market applications. The MADS-001317-1500 is designed for customers who need a versatile, low cost, ultra-small Schottky solution for Police Radar, Point to Point, Electronic Warfare, and Aerospace and Defense applications.
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
The crew of the International Space Station is boldly going where no one has gone before - to see the new "Star Trek" film. The three astronauts were offered a sneak peak of "Star Trek Into Darkness" days before it opens Thursday on Earth, seeing it not in 3-D, but Zero-G.
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....
In a high-flying, perfectly pitched first, an astronaut on the International Space Station is bowing out of orbit with a musical video: his own custom version of David Bowie's "Space Oddity." It's believed to be the first music video made in space, according to NASA. Canadian astronaut Chris Hadfield's personalized rendition of "Space Oddity" was posted on YouTube on Sunday....
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.
