Heads-up display aims to give Soldiers improved situational awareness A novel technology called "Tactical Augmented Reality" (TAR) is now helping Soldiers precisely locate their positions, as well as the locations of friends and foes. It even enables them to see in the dark, all with a heads-up display device that looks like night-vision goggles.

Printed sensors monitor tire wear in real time Electrical engineers at Duke University have invented a printed sensor made of metallic carbon nanotubes that can monitor the tread of tires in real time. In its first demonstration, the cheap, simple innovation shows it can measure tire thickness down to the millimeter while surviving the harsh conditions of the interior of a tire.

New innovative way to take up tolerances Smalley Linear Springs are a continuous wave-formed (marcelled) wire length produced from spring-tempered materials. They act as a load-bearing device, having approximately the same load/deflection characteristics as a wave spring. Linear Springs are now available as a standard part in carbon and stainless steel, with over 200 sizes.

NIST seeks help with 'Unidentified Museum Objects' The museum collection at the National Institute of Standards and Technology (NIST) includes hundreds of artifacts that tell the story of one of the nation's oldest physical science laboratories, and its predecessor NBS, that reflect the larger history of American scientific research. But not every item in the collection has been identified. In fact, they're in the possession of quite a few thingamajigs.

Compact hexapod for industrial alignment applications PI has added a higher performance model to its range of compact hexapods. The new H-811.i2 provides twice the velocity along with sensor resolution up to eight times higher compared to the current H-811.D2 miniature hexapod. The compact size, robust design with low-friction ballscrews, brushless motors, and powerful controller with multi-axis alignment capabilities make the new hexapod an ideal tool for high duty-cycle alignment applications in optics, automotive, and photonics applications. Specifications, datasheets, more information > Read technical articles and applications of PI hexapods >

Rotate an object to a precise angular position Goniometer stages can measure angles of objects such as crystals or move an object to a precise angular position along an arc in relation to a fixed point in space. Two goniometer stages mounted in an alpha-beta configuration (stacked) can rotate an object around a fixed point in space on a spherical surface. Optimal Engineering Systems (OES) offers stacked, precision-aligned goniometer stages like the compact AK110-15-10 with a rotation center 50 mm above the upper stage. Goniometers are used for identifying crystals, examining cutting edges of medical instruments, estimating hyperspectral bidirectional reflectance, gloss measurements, measurements of radiation patterns of LEDs, directing lasers, aligning mirrors, and manufacturing quartz oscillator plates using quartz cutting X-rays.

Gun metal: Army cold spray process reclaims unrepairable metal parts The U.S. Army Research Lab and the South Dakota School of Mines have commercialized a portable system to reclaim unserviceable parts and reduce the amount of maintenance required by military and commercial sectors. The cold-spray process uses mixtures of metallic and nonmetallic particulates in powder form accelerated at supersonic speeds onto the surface of a worn or damaged part to restore it back to its original dimensions.
