The materials included in the collection of documents describe the research of the NASA Ames Fatigue Countermeasures Group (FCG), which examines the extent to which fatigue, sleep loss, and circadian disruption affect flight-crew performance. The group was formed in 1980 — in response to a...

A specialty chemical company is seeking innovative green, renewable raw materials, products, and processes for replacement of existing non-environmentally friendly solvents while not compromising the performance or significantly increasing the costs. The solutions should be biodegradable, low/non- VOC, low...

A method is sought to provide a real-time quantitative measure of the volume of milk consumed as a baby breast-feeds. The solution must be safe, environmentally sound, non-invasive, retail for under $50, and should not interfere with mother- newborn bonding. It should be compatible with home use and relatively...

Creating the future is about change, creativity, and risk - the core building blocks that foster innovation. For the past five years, Emhart Teknologies has partnered with NASA Tech Briefs in challenging the engineering community through our “Create the Future”...

Parallel-Plate Motorcycle Frame Martin O’Toole, Revolution Motorcycles, Doylestown, PA The concept of the parallel-plate framing system is to eliminate the welded tubular frame. The components are made using 3-axis CNC milling, waterjet, and laser-cutting machines. By removing the...

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...
