Elbit has introduced a new, lightweight, low-profile remotely operated weapon station designed for light vehicles. The system designated 'Electrically Remotely Controlled Weapon Station - Medium' (ERCWS-M) mounts a modular electro-oprtical payload, configurable to carry customer furnished EO sensors. The payload is mounted on an independent traverse and elevation gear, enabling the operator to decouple the weapon from the EO sensors, performing surveillance and reconnaissance activity while the gun is elevated 60 degrees up, without 'pointing' at specific targets. The EO payload can also perform limited lateral (traverse) movements to improve fire correction and compensation when firing an Automatic Grenade Launcher. Other weapons carried by the system include 7.62 and 12.7mm machine guns. All photos: Defense Update. The new system has already been selected for the new Austrial Armored Protected Vehicles procured in Italy.

One for All: AAI Textron’s UAV Control System
Can the Army create a universal ground control system for UAVs? The ability to use hundreds of comparatively cheap UAVs from different manufacturers has been a blessing to ground forces, who finally have the comprehensive aerial coverage they want. It can also be a curse. If each system has its own unique controller and vehicle – or worse, its own receiver and screen – the result will be chaos.
Enter AAI’s One System® ground control offerings, which are a step toward a more universal future. This Spotlight article covers the One System concept, its ongoing development, its current reach, and future technology initiatives and requirements that will affect UAV ground control…

US Air Force to Test Scramjet Aircraft
The US Air Force has been developing an aircraft that employs an air-breathing scramjet engine, and hopes to run test flights in the fall of 2009. Officials hope the X-51 “Waverider” aircraft will provide high speed aircraft for reconnaissance or strike missions, and eventually the engines will be used for rockets to deploy satellites in space.
“The long-range goal of this for the Air Force is access to space,” said Charlie Brink, an Air Force Research Laboratory propulsion directorate official who manages the X-51 program from Wright-Patterson Air Force Base.The first test flight of the X-51 will be on Oct. 27, 2009, launched from a B-52 aircraft with a missile booster to at least Mach 4.5, the minimum speed at which the air-breathing scramjet engine operates, before the scramjet kicks in and accelerates the vehicle to at least Mach 6 — six times the speed of sound.

Wide Field Camera 3
After astronauts install the Wide Field Camera 3 (WFC3) during SM4, it will continue the pioneering tradition of previous Hubble cameras, but with critical improvements to take the telescope on a new voyage of discovery. Together with the new Cosmic Origins Spectrograph (COS), WFC3 will lead the way to many more exciting scientific discoveries.
Instrument Overview
WFC3 will study a diverse range of objects and phenomena, from young and extremely distant galaxies, to much more nearby stellar systems, to objects within our very own solar system. Its key feature is its ability to span the electromagnetic spectrum from the ultraviolet (UV, the kind of radiation that causes sunburn), through visible/ optical light (what our eyes can detect), and into the near infrared (NIR, the kind of radiation seen with night-vision goggles). WFC3 extends Hubble’s capability not only by seeing deeper into the universe but also by providing wide-field imagery in all three regions of the spectrum—UV-Visible-NIR. It is this wide-field “panchromatic” coverage of that makes WFC3 so unique. As an example, WFC3 will observe young, hot stars (glowing predominantly in UV) and older, cooler stars (glowing predominantly in the red and NIR) in the same galaxy.

Future Helicopters Get SMART
Helicopters today are considered a loud, bumpy and inefficient mode for day-to-day domestic travel—best reserved for medical emergencies, traffic reporting and hovering over celebrity weddings.
But NASA research into rotor blades made with shape-changing materials could change that view.
Twenty years from now, large rotorcraft could be making short hops between cities such as New York and Washington, carrying as many as 100 passengers at a time in comfort and safety.
Routine transportation by rotorcraft could help ease air traffic congestion around the nation's airports. But noise and vibration must be reduced significantly before the public can embrace the idea.

Cheap Plastic Could Improve Electronic Devices
Cheap plastic in CDs and DVDs could one day improve the integrity of electronics in aircraft, computers and handheld electronics, researchers said today.
Shay Curran, associate professor of physics at University of Houston , and his research team created ultra-high electrical conductive properties in plastics, called polycarbonates, by mixing them with carbon nanotubes.
Computer failure, for instance, results from the build up of thermal and electrical charges, so developing these polymer nanotube composites into an antistatic coating or to provide a shield against electromagnetic interference would increase the lifespan of computing devices, ranging from PCs to PDAs.

Turning the Tide to Energy: New Concept Could Harness the Power of Ocean Waves
NASA researchers who developed a new way to power robotic underwater vehicles believe a spin-off technology could help convert ocean energy into electrical energy on a much larger scale. The researchers hope that clean, renewable energy produced from the motion of the ocean and rivers could potentially meet an important part of the world's demand for electricity.
Many different methods already exist for using moving water to create power. Hydroelectric plants, for example, are among the most established and least expensive sources of electricity. They benefit from the large hydrostatic pressure difference between the water surface behind the dam and the turbines that can be harnessed to produce power. But the power that can be produced in this manner is limited, because most of the suitable rivers already have hydroelectric dams.

Ultimate Fridge Magnets Could Save Energy
Magnetic refrigeration technology could use 20-30 percent less energy than traditional gas-compression fridges and air conditioners used today. But the material needed to make them work hasn't been determined.
Now a step has been made toward figuring out what materials will work best.
A magnetic refrigeration system works by applying a magnetic field to a magnetic material — some of the most promising being metallic alloys — causing it to heat up. This excess heat is removed from the system by water, cooling the material back down to its original temperature. When the magnetic field is removed the material cools down even further, and it is this cooling property that researchers hope to harness for a wide variety of cooling applications.

Patent reveals Google's book-scanning advantage
Sometimes overlooked in the Sturm und Drang about Google Book Search is any consideration of the mechanics of economically scanning the books in the first place, but a patent awarded to Google gives insight into how the search behemoth accomplishes the task.
In short, Google has come up with a system that uses two cameras and infrared light to automatically correct for the curvature of pages in a book. By constructing a 3D model of each page and then "de-warping" it afterward, Google can present flat-looking pages online without having to slice books up or mash them onto a flatbed scanner.

Photo-direct vehicle camouflage matches battlefield
While military camouflage patterns for vehicles have evolved, the application process has been stuck in the spray booth. Now, however, GI equivalents of Earl Scheib can apply a precut "wrap" of adhesive vinyl that will blend in on virtually any battlefield.
The process is similar to the advertising and decorative wraps commonly seen on cars and buses, except that this product from Military Wraps, called Photo Veil, is lightweight and incorporates images from cameras on drones, satellites, or lidar in the field and loops them back to be applied to vehicles or equipment as site-specific, high-resolution camouflage.

GPS Accuracy Could Start Dropping in 2010
At the end of April 2009, the U.S. Government Accountability Office released a report expressing concern about the Air Force's modernization and maintenance of the GPS system. Constant replacement and upgrading of satellites is necessary, especially with hardware that's been operating in space for almost two decades.
The GAO's report draws attention to problems that the Air Force has had in working with contractors to build and launch GPS satellites within cost and schedule goals. Some of the problems stem from government acquisition methods that didn't provide for enough oversight, and added requirements that resulted in cost and schedule overruns.

Reliable Acoustic Path Vertical Line Array
DESCRIPTION: In recent years the U.S. Navy has researched the utility of deep water (i.e., 6 km depth, 3 deg C temperature) acoustic sensing technologies that exploit the reliable acoustic path (RAP) [1] using vertical line arrays (VLAs) of vector sensors [2,3]. The first RAP VLA array was large and deployed over the side of a research vessel [3]. The sensing nodes consisted of a pressure hydrophone, a triaxial pressure-gradient hydrophone, and an electronics housing all contained within a free-flooding plastic frame having a diameter and length of 13-in x 41-in. The measured acoustic signals were routed to a central node that served as a data recorder. Future arrays will be smaller and deployed from tactical naval platforms using existing packaging modalities

The Future Sneaks Up On You
The U.S. Army is caught in the middle of a debate over its future. Many politicians want to turn the army into a force specializing in irregular warfare (as seen in Iraq and Afghanistan). Many generals, and some politicians, warn that the army is still needed for conventional warfare, against a foe with lots of armor, aircraft and trained troops. While the army still contains many armored unit (about half the 45 brigades are equipped with tanks and other armored vehicles), many of the tank crews have gone to Iraq and served as infantry. In the last five years, very little mechanized warfare training has been done. The troops train for Iraq and Afghanistan, which means infantry fighting.

Illusion Cloak Makes One Object Look like Another
Just when you thought invisibility cloaks couldn't get any weirder, researchers come up with this: a way to make one object look like any other.
Invisibility cloaks work by steering light around a region of space, making any object inside that region invisible. In effect, an invisibility cloak creates the illusion of free space. This is possible because of a new generation of artificial materials called metamaterials that can, in principle at least, steer light in any way imaginable. Indeed, various teams have built real invisibility cloaks that hide objects from view in both the microwave and optical bands.
Now Che Chan and pals from the Hong Kong University of Science and Technology say that metamaterials could be used for an even more exotic effect: for cloaks that create the illusion that a different object is present.
