Advanced Pattern Recognition Technologies These sensors, algorithms, neural network systems, optics and camera...

University of California, Riverside nanotechnologists have controlled the color of very small particles of iron oxide suspended in water simply by applying an external magnetic field to the solution. The discovery has potential to greatly improve the quality and size of electronic display screens and to enable the manufacture...

The Defense Advanced Research Projects Agency (DARPA) is seeking proposals for LANdroids -- a fleet of miniature, intelligent mobile robots that will aid military communications in urban settings. The goal is to create small, inexpensive robotic radio relay nodes that dismounted warfighters will drop as they deploy. The nodes...

Origin 8 Windows-based data analysis and graphing software from OriginLab Corp., Northampton, MA, has been named NTB's Product of the Month for July. The software operates around a revamped workbook space, which allows results of an analysis to be placed into a worksheet within the raw data's workbook. Parameter values,...

An electromagnetic actuator is a highly sensitive motion control device that employs more reliable and cleaner electromagnetic technologies to replace slower, less precise, larger, noisier, and environmentally unfriendly hydraulic omponents. This patented technology uses an armature in the form of a piston that moves on its own...

Researchers at Purdue University's Birck Nanotechnology Center have used nanotechnology to create transparent transistors and circuits, a step that promises applications from e-paper and flexible color screens for consumer electronics, to "smart cards" and heads-up displays in auto windshields. The transistors are made of...
