LabVIEW for Measurement and Data Analysis

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.

Torque Measurement Methods

This white paper from HBM showcases torque measurement products in action and details how measurement experts measure torque. It outlines torque measurement in the following areas: calculation from electrical power, measuring reaction torque, measuring in-line torque, and strain gages in torque measurement.

New Coating

Posted March 29th, 2007 by

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 molecule is tipped with a Teflon-like “functional group” made with fluorine. Water molecules pass through theTeflon-like layer, which acts as a barrier to the larger oil molecules. The water is then attracted to the polyethylene glycol immediately adjacent to the glass surface.

Tech Needs of the Week

Posted March 29th, 2007 by

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 for the wavy edge utilizing the current machine. To respond to this Tech Need, click here.

Screen-printing, foil-stamping, or laser-marking methods are needed to engrave permanent markings on stainless steel. The method will be used on both flat surfaces and curvatures. The visibility of the engravings must be clear and prominent. The method will be used on stainless steel dining ware and cups/mugs. To respond to this Tech Need, click here.

The Technology Needs of the Week are anonymous requests for technology, distributed through the yet2.com marketplace, that you and your organizationmay be able to fulfill. Responding to a Tech Need is the first step to gaining an introduction with a prospective “buyer” for your technology solution.

NASA News

Posted March 29th, 2007 by

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.

The primary goal of the Airspace Systems Program is to develop revolutionary concepts, capabilities, and technologies that will enable significant increases in the capacity, efficiency, and flexibility of our National Airspace System. A major focus of the Subsonic Fixed Wing project is to develop improved prediction methods and technologies for future subsonic aircraft with lower noise, lower emissions, and higher performance.

Sugar Battery

Posted March 27th, 2007 by

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 during further testing and refinement, it could be ready for commercialization in three to five years.

“This study shows that renewable fuels can be directly employed in batteries at room temperature to lead to more energy-efficient battery technology than metal-based approaches,” said study leader Shelley Minteer, PhD, an electrochemist at St. Louis University. “It demonstrates that by bridging biology and chemistry, we can build a better battery that’s also cleaner for the environment.”
