The Army is using a new helicopter simulator, called the Non-rated Crew Member Manned Module (NCM3), to train helicopter crews on the rear of both the CH-47 Chinook and UH-60 Black Hawk. Through specially created virtual reality glasses, which fit the same as night vision goggles, soldiers can practice and...

University of Utah chemists developed a method to design and test new catalysts – substances that speed chemical reactions and are crucial for producing energy, chemicals and industrial products. By using the new method, the chemists also discovered that the sizes and electronic properties of...

Idaho National Laboratory researchers have recently demonstrated a new sample preparation technique that makes it easier to examine irradiated fuel at the nanoscale. This accomplishment revealed material behavior that suggests increased stability of a new type of reactor fuel. Further study and...

"Create the Future" Design Contest sponsored by PTC®, COMSOL, and Tech Briefs Media attracts over 900 innovative product ideas from engineers and students in 50 countries. New York, NY – A new invention could protect millions from contracting...

Coherent terahertz radiation has historically been very difficult to generate, and the search for an easy-to-use, compact source continues today. Northwestern University researchers recently developed a simpler way to generate single-chip terahertz radiation — a discovery that could benefit...

A new method of extracting sugars from biomass could lead to more sustainable, inexpensive biofuel production. Unlike more expensive techniques that focus on enzymes, this method, developed at Iowa State University, relies on pyrolysis of lignocelluslosic biomass: quickly heating the biomass without oxygen to...

University of Texas at Austin researchers have discovered how to extract and use information in an individual image to determine how far objects are from the focus distance, a feat only accomplished by human and animal visual systems until now. Like a camera, the human eye has an auto-focusing...

The black box, an airplane’s digital flight-data recorder, holds massive amounts of data, documenting the performance of engines, cockpit controls, hydraulic equipment, and GPS systems, typically at regular one-second intervals throughout a flight. Analysts have been studying...

A technology commonly used for designing buildings, bridges, and aircraft has now been used to aid breast tissue reconstruction in cancer patients. Researchers from Australia, Germany, Singapore, and Georgia Tech have used computer-aided design (CAD) to create an extremely accurate mold of...

This week's Question: Google Wallet, an Android mobile app launched earlier this month, is slowly being rolled out to the public. The application allows users to make purchases with their phones. The technology uses near field communication (NFC) chips to store and remit credit card data,...

The 2220 Series brushless DC oil-less air compressor from Thomas Division (Sheboygan, WI) is designed for applications requiring a compact compressor with variable output. The unit weighs 1.48 pounds and measures 3.8 × 2.64 × 4.7". It features a variable speed motor that produces flow to 1.2 cfm and pressure to 30 psi. It uses...

Improved devices have been proposed for collecting sweat for biochemical analysis — especially for determination of the concentration of Ca2+ ions in sweat as a measure of loss of Ca from bones. Unlike commercially available sweat-collection patches used previously in monitoring...

Phil McAlister, acting director of commercial spaceflight development, oversees the efforts of the Commercial Crew Development and Cargo programs. The dual initiatives spur efforts within the private sector to boost human spaceflight...

For safety and efficiency, nuclear reactors must be carefully monitored to provide feedback that enables the fission rate to be held at a constant target level via adjustments in the position of neutron- absorbing rods and moderating coolant flow rates. For automated reactor control, the...

In the past, solid electrolytes have mainly been used as oxygen sensors for automobiles. This type of sensor measures the difference between the oxygen partial pressures of a reference electrode and a measurement electrode, and always requires a...

A cytometer now under development exploits spatial sorting of sampled cells on a microarray chip followed by use of grating-coupled surface-plasmon-resonance imaging (GCSPRI) to detect the sorted cells. This cytometer on a chip is a prototype of contemplated future miniature cytometers that would be suitable for rapidly...

A process has been examined for bonding a platinum resistance thermometer (PRT) onto potential aerospace materials such as flat aluminum surfaces and a flexible copper tube to simulate coaxial cables for flight applications. Primarily, PRTs were inserted into a...

Tactile sensors are currently being designed to sense interactions with human hands or pen-like interfaces. They are generally embedded in screens, keyboards, mousepads, and pushbuttons. However, they are not well fitted to sense interactions with all kinds of objects.
