The World's First -- and Best -- Linear Motion Guides THK's original technology is behind the smooth and silent movement of the "Linear Motion System." The LM Guide is our major product that put the rolling of the linear motion part into practical use for the first time in the world. This improves the accuracy, rigidity, energy saving, velocity, productivity, and service life of the machine. THK offers a full support system from the beginning design phase throughout the maintenance, and follow-up service.

| Aluminum treads on Mars Curiosity rover show open breaks and tears | |
 A routine check of the aluminum wheels on NASA's Curiosity Mars rover has found two small breaks on the rover's left middle wheel -- the latest sign of wear and tear as the rover continues its journey, now approaching the 10-mile mark. NASA lays out the problem, and Designfax delves a little deeper into the cause.

Wings: Next Big Thing in Army aviation? Lockheed Martin S-97 RAIDER is fast and furious The Lockheed Martin/Sikorsky S-97 RAIDER is a next-gen light tactical prototype helicopter that can reach speeds of more than 220 knots, nearly double the speed of a conventional helicopter, and is capable of flying at 10,000 feet in 95°F heat. It can carry six troops and external weapons, and it aims to redefine helicopter flight during the 21st century. Based on Sikorsky's Collier Award-winning X2 Technology, RAIDER incorporates the latest advances in fly-by-wire, flight controls, vehicle management systems, and systems integration. It also has retractable landing gear, active vibration control, a composite fuselage, active elevator and rudders, split torque transmission, and a rigid co-axial rotor system. These technologies enable the aircraft to operate at high speeds while maintaining the low-speed handling and maneuverability of conventional, single main-rotor helicopters.

Top Engineer's Toolbox: Metal tape measure technology grows up When first-timers see the Zippermast rise into the air from an unmanned vehicle, they are amazed by how high it can be extended. Inspired by the lowly metal tape measure design, the compact and super-sturdy Zippermast consists of three interlocked steel tapes that also function like a locking zipper, lifting cameras and sensor equipment up to 40 ft in the air. A small DC motor from FAULHABER provides the unique design with reliable retraction and extension, all incorporated into an amazingly small base housing.

U.S. military 3D prints working grenade launcher and ammo What's better than a 3D-printed prototype grenade launcher? One that works -- with 3D-printed ammo -- of course. Researchers at the U.S. Army Armament Research, Development and Engineering Center (ARDEC) and industry partners have been working hard to push the envelope in 3D-printing prototype technology. Did they succeed? Yup -- with a bang.

OEMS and Motion Control: Optimized Performance vs. 'Good Enough' OEMs have to balance a lot of competing factors -- cost, precision, safety, performance -- in order to build a superior machine. The motion experts at Kollmorgen discuss in depth the considerations, processes, and challenges machine engineers face when making motion-related decisions. Learn how flexibility, connectivity, modularity, changeover time, and costs can converge to create a total system approach that takes machines from 'good enough' to best in class.

| Cool Tools: Ultra-wide Samsung 49-in. HDR monitor | |
 Officially it's a gaming monitor, but who says your design work shouldn't be a little fun? The new Samsung ultra-wide 49-in. CHG90 display features powerful, High Dynamic Range (HDR) picture enhancement technology typically reserved for high-end TVs, an exceptionally wide range of accurate color reproduction using QLED Quantum Dot technology, and AMD's new Radeon FreeSync 2 tech for stutter-free motion. Now, having two smaller monitors on your desktop is so 2016.

Top Product: Infrared LED optimizes license plate recognition and more Osram Opto Semiconductors is expanding its family of high-power infrared Oslon LEDs for illumination solutions to include a new wavelength, 810 nm. The new SFH 4703AS infrared emitter will improve the performance of inspection and scanning camera systems, such as those used to read license plates. The additional wavelength enhances image contrast, making it easier to read patterns from recorded images at any time of day. At 1-A current, the emitter generates 1 W of optical power. With this new device, designers can now choose from mutually compatible emitters in three different wavelengths.
