Using Hollow Core Plastic Bragg Fiber to Deliver Ultrashort Pulse Laser Beams

Ultrashort pulse (USP), or “ultrafast,” lasers emit extremely brief pulses of light, generally with duration of a picosecond (10-12 seconds) or less. The pulses are characterized by a high optical intensity that induces nonlinear interactions in various materials, including air.

Communications Systems Support NASA’s Unmanned Aircraft

Communications systems and support equipment L-3 Communications Corp. Communications Systems West Salt Lake City, UT 801-594-2000’s Dryden Flight Research Center in Edwards, CA has chosen L-3 Communications Systems West to provide engineering, technical, and product support services for the center’s operation of two Global Hawk unmanned aircraft. The contract supports Dryden’s planned operation of the two aircraft, their associated ground control station, and related systems. L-3 will be responsible for providing specialized analysis, engineering, functional tests, hardware or software development, or testing that requires specific L-3 proprietary data.

Handheld Labeler is Key to International Space Station’s Organizational System

PT-1880 handheld electronic labeler Brother International Bridgewater, NJ 908-704-1700 October 2007, the crew of NASA’s International Space Station (ISS) was having difficulty clarifying the often complex layout of the ISS panels and systems. The crew contacted Mission Control and had a NASA worker purchase Brother Ptouch ® 1880 electronic labelers, which were then sent up to the ISS on the next shuttle mission. The PT-1880, an easy-touse handheld labeler, is now an important component of the ISS’s organizational system.

BEI Duncan’s Steer-by-Wire Technology Improves Fuel Efficiency for AGCO Challenger® Tractor

Off-highway tractors slog through mud, muck, and other rough terrain on a daily basis. Achieving high reliability and performance in spite of these harsh conditions requires technology at its best. To improve fuel efficiency and reliability while decreasing manufacturing costs, the AGCO Challenger® track tractor went through a major redesign from the ground up.

Delta Motion Controller Helps ADI Improve Automotive Chassis Testing

There’s a science to testing metal structures for rigidity and performance under stress. The development of new testing methodologies is continuing at a fast pace, aided by innovations in supporting technologies. For example, motion controllers have evolved to support special capabilities for exerting real-world forces on structures that can deliver, in a matter of hours or days, the loads and movement that assemblies would otherwise encounter in a whole lifetime of use. And motion control electronics connected to hydraulic or electromechanical actuators can submit assemblies to stresses and measure responses in a “clean” environment that would be difficult or expensive to accomplish in the field.

Heidenhain Encoders Help TRW Machine Ford SUV Parts

TRW has been making parts for the automotive industry for many years, but when Ford Automotive considered giving them the contract to manufacture the rear toe-links for their Navigator and Expedition SUVs, their traditional lathes were considered inadequate for the task. The solution was to upgrade the lathes with Heidenhain linear encoders.

Shortwave Infrared - The Latest Weapon in the War on Terror

Keeping one step ahead of our adversaries is top priority for security forces with terrorist threats growing daily around the world. Intelligence, surveillance and reconnaissance are the core situational awareness tools for the global war on terrorism (GWOT). Just as night vision equipment has denied terrorists the cover of darkness for more than a couple of decades, emerging shortwave infrared imaging technology is now removing weather and environmental limitations from the ISR equation.Shortwave infrared exploits the third and final atmospheric window in the infrared spectrum. SWIR, long the domain of the high altitude U-2 spy plane with its cryogenically-cooled focal plane array (FPA) technology, has powerful capabilities not widely known outside the intelligence community until recently. SWIR makes long slant range imaging possible under practically any conditions. A revolution in imaging has recently been developed via breakthrough, indium gallium arsenide (InGaAs) FPA technology, resulting in lighter weight, more compact cameras. These new uncooled InGaAs imagers offer the advantages of the short-wave infrared spectrum to see beyond the visible, and because of their ultra-compact design, they can be implemented on the smallest UAVs (unmanned aerial vehicles) and man-portable platforms.
