Tech Needs of the Week

An advanced materials company is seeking new coating technologies that display excellent weathering and durability performance. The coatings will be applied in wet format to glass substrates and need to be optically transparent, have a hardness of at least 2H, and have excellent outdoor durability. To respond to this Tech Need, click here. A coating is needed for application on top of an optical layer, which consists of a scratch-sensitive material. The coating should provide protection against mechanical damage and will be applied either by spray coating, doctor blade coating, or dip coating. 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 organization may 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.

White Papers

Three Levels of Data-Logging Software from National Instruments This paper introduces the three levels of data-logging software for use with National Instruments’ DAQ devices -- NI LabVIEW SignalExpress, NI LabVIEW SignalExpress LE, and NI LabVIEW. Unique Method for Orifice Production This white paper from Bird Precision explains that in producing accurate, repeatable orifices, all the variables that might influence the Cd Value (Coefficient of Discharge) must be controlled during production.

Intelligent Sunglasses

Researchers at the University of Washington (Seattle, WA) have designed prototype sunglasses that darken instantaneously, using electrochromic materials that change transparency depending on the electric currents running through them. The wearer spins a tiny dial on the arm of the glasses to change lens color or shade. Sandwiching a gel between two layers of electrochromic material created the lenses. Applying a small voltage moves charged particles from one layer to another, changing the transparency. A single watch battery is able to power thousands of transitions. Once the glasses are a certain tint, they will stay that way without power for about 30 days. Organic molecules allowed the researchers to create colored lenses. For more information, click here.

Current Attractions

Each month, NTB highlights tech briefs related to a particular area of technology in a special section known as Technology Focus. Here's an Insider look at the April focus on Sensors. Wearable Environmental and Physiological Sensing Unit Developed at NASA’s Ames Research Center, the wearable environmental and physiological sensing unit (WEPS) is a prototype of systems to be worn by emergency workers to increase their level of safety. The WEPS includes sensors that measure a few key physiological and environmental parameters, a microcontroller unit that processes the digitized outputs of the sensors, and a radio transmitter that sends the processed sensor signals to a computer in a mobile command center. (Page 28) Iterative-Transform Phase Retrieval Using Adaptive Diversity NASA Goddard Space Flight Center’s phase-diverse iterative- transform phase-retrieval algorithm enables high-spatial-frequency, high-dynamic-range, image-based wavefront sensing. No prior phase-retrieval algorithm has offered both high dynamic range and the capability to recover high-spatial-frequency components.

Fancar Aircraft

Engineers at Urban Aeronautics (Yavne, Israel) are developing the prototype X-Hawk Fancraft(TM), a Vertical Take-Off and Landing (VTOL) vehicle whose rotors, unlike a helicopter, are contained in the body of the craft. Originally envisioned as a medical evacuation vehicle, X-Hawk’s modular cargo bay allows for tailor-made, task-specific configurations that would enable the aircraft to be an all-around workhorse. Some other applications could include power line maintenance, bridge inspection, and ship-to-shore taxi service. Quieter than a helicopter, a vane system enables the X-Hawk to maneuver laterally without the need to roll. This is essential if a mission necessitates hovering directly in contact with the side of a structure. For more information, click here.
