Thousands of engineers and scientists rely on National Instruments' LabVIEW for a variety of applications. This paper focuses on the capabilities that make LabVIEW the right tool for data and measurement analysis.

Materials engineers at Purdue University have created a new type of coating that attracts water yet beads oils, promising potential applications such as "self-cleaning" eyeglasses and antifogging car windshields and ski goggles. The coating consists of a single-molecule-thick layer of a material called polyethylene glycol, where each...

Technical assistance is needed for the manufacture of serrated, scalloped (concave), and wavy (convex) bandknife blades. Of interest are 14 and 16 TPI (teeth per inch) by blanking for the serrated edge. Blanking has been achieved for the scalloped edge, but the resulting shape is not satisfactory. Blanking was not achieved...

The "Research Opportunities in Aeronautics" announcement from NASA's Aeronautics Research Mission Directorate seeks research in several new topic areas for the Next Generation Air Transportation System Air Traffic Management Airspace Project and the Subsonic Fixed Wing Project.

Researchers at Saint Louis University (St. Louis, MO) have developed a biodegradable fuel cell battery that runs on virtually any sugar source, from soft drinks to tree sap, and has the potential to operate three to four times longer on a single charge than conventional lithium ion batteries. If the battery continues to show promise...

A low-cost fingerprint detector, using off-the-shelf components integrated into a compact, portable unit, is available. The fingertip is moved relative to a skin-resistance-sensing array to produce a 'reference trajectory signal' that is stored in memory. The fingertip is moved again to produce a 'sample trajectory signal.'...

Engineers at Moteur Developpment International (MDI, Luxembourg City, Luxembourg) have designed a prototype car that is powered by compressed air. The vehicle has a tubular chassis that is glued together, a fiberglass body, and uses wireless communication between its components. The engine weighs less than half that of a standard car....

Astronomers have woven NASA Hubble Space Telescope images of Saturn, its rings, and several of its moons into three movies. Each movie highlights unique times in the planet's 30-year waltz around the Sun. Hubble snapped only about a dozen images during each of these three events, so astronomers created software to extend the photos...

Nanotech Briefs® magazine is accepting nominations for its third annual Nano 50 awards competition. The Nano 50 recognizes the top 50 technologies, innovators, and products with the greatest potential to advance the commercialization of nanotechnology.

Using lasers and tuning forks, researchers at Pacific Northwest National Laboratory have developed a chemical weapon agent sensing technique called Quartz Laser Photo-Acoustic Sensing (QPAS) that promises to meet or exceed current and emerging defense and homeland security chemical detection requirements. The instrument is...

A coating that is hard and has a high modulus of elasticity is needed for application to polyvinyl alcohol (PVA) optical films. Excellent coating adhesion and optical transparency are mandatory. The coating must withstand a force greater than 13,000 MpA, and offer a pencil hardness of B or over.To respond to this Tech Need...

By 2020, NASA plans to establish a long-term human presence on the Moon. To make this possible, a reliable stream of consumables such as fuel, food and oxygen, spare parts, and exploration equipment would have to make its way from the Earth to the Moon as predictably as any Earth-based delivery system. To figure out how to do...

BI Technologies Electronic Components Division (Fullerton, CA) introduced the EN line of rotary mechanical encoders. The two-bit gray code incremental encoders are housed in 11, 12, and 16 mm packages, and feature detents and push-on switch options.

Developed at NASA’s Marshall Space Flight Center (Huntsville, AL), a micro-commanding rotational-position-control system offers the advantage of less mechanical complexity, susceptibility to mechanical resonances, power demand, bulk, weight, and lower cost, relative to prior rotational-position-control systems based on...

A research team led by Chang Liu at the University of Illinois at Urbana-Champaign (UIUC, Champaign, IL) has built a sensor for underwater vehicles equivalent to a sensory organ found on fish called the lateral line. In fish, the lateral line provides guidance for synchronized swimming, obstacle avoidance, and prey/predator detection...

Medical scientists at Johns Hopkins University (Baltimore, MD) have constructed the "PneuStep," a prototype pneumatic step motor that is the first of its kind. The motor was developed as part of a project for a robot that could operate precisely within the closed bore of high-intensity MRI equipment. The pneumatic nature of the...

Researchers at Massachusetts Institute of Technology (MIT) have created customizable hydrogel microparticles capable of identifying different biomolecules, disease monitoring, drug discovery, or genetic profiling. Each particle is equipped with a bar-coded ID and one or more probe regions that turn fluorescent when they detect...

Engineers at the Humanoid Robot Research Center (Taejon, S. Korea) have constructed the prototype HUBO-FX1, a human-riding "robotic chair" capable of carrying a person or a load of 100 kg. The user sits in a chair structure mounted on two robot legs, and controls ambulatory motion by way of a joystick. The HUBO-FX1 can walk forward,...

A self-biased solar cell is available that provides improved conversion efficiency. Loss of carriers at the back surface of the battery is decreased, and open circuit voltage and quantum efficiency near a long wavelength are increased. View this technology here.
