Single-walled, jacketed aluminum tanks have been conceived for storing liquefied natural gas (LNG) in LNG-fueled motor vehicles. Heretofore, double- wall steel tanks with vacuum between the inner and outer walls have been used for storing LNG. In comparison with the vacuum-insulated steel tanks,...

The immediately preceding article includes an example in which a composite overwrap on a pressure vessel contains wound filaments made of a hybrid of high-strength carbon fibers and poly(phenylene benzobisoxazole) [PBO] fibers. This hybrid material is chosen in an effort to increase the...

Structural components made of amalgams can be made to have tensile strengths much greater than previously known to be possible. Amalgams, perhaps best known for their use in dental fillings, have several useful attributes, including room- temperature fabrication, corrosion resistance, dimensional...

Software is currently being developed at Ohio State University that will one day help scientists operate big-budget research instruments, such as high-powered microscopes and telescopes, over the Internet. The need for such capability, which is being driven by the high cost of doing research, is growing rapidly. By using...

The John H. Glenn Research Center introduces the Portable Unit for Metabolic Analysis (PUMA), an instrument that measures quantities indicative of human metabolic function. The PUMA makes time-resolved measurements of temperature, pressure, flow, and the partial pressures of oxygen and carbon dioxide in breath during inhalation and...

Abdominal obesity is a known independent risk factor for heart disease. Based on results of the European Prospective Investigation into Cancer cohort study (Epic-Norfolk), researchers have found that using the waist-hip ratio rather than waist measurement alone is a better predictor of heart disease risk. The research was based on...

A company is seeking a powder slurry coating technology, where substrates are coated with powder slurry in an organic binder and then heat treated to diffuse the coating onto the substrates. Any proposed powder slurry coating technology should involve a powder composition based on Co-based or Ni-based alloys. It should be a...

Researchers from Johns Hopkins and the University of Pennsylvania have uncovered another reason why the Myc protein - one of the most commonly activated proteins in cancer - is so dangerous. Myc can stop the production of at least 13 microRNAs, small pieces of nucleic acid that help control which genes are turned on and off. A...

High-performance, single photon sources are closer to reality. A single photon can be used to implement secure optical communication, also known as quantum cryptography. According to scientists, a single photon signature that took eight hours five years back can now be achieved on a millisecond time scale. This was achieved...

An optical device that peers through the eyes of a mouse enables scientists to monitor the cells passing through its bloodstream, holding hope for researchers treating cancer and other diseases. The device, developed by researchers from the Wellman Center for Photomedicine at Massachusetts General Hospital and Harvard Medical...

A method to detect image position errors includes forming a first pattern with a symbol embedded therein and a second pattern which, when positioned on the first pattern, exposes the symbol if the misalignment between the first and second patterns exceeds a position error tolerance. The symbol is perceivable with the unaided eye,...

Finding the source of pollutant emissions is no easy task when one has to look inside a dirty combustion chamber. But an Iowa State University researcher may have a solution. Terry Meyer, an assistant professor of mechanical engineering at Iowa State, is using laser-based sensors to capture images at upwards of thousands of...

Each month, NTB highlights tech briefs related to a particular area of technology in a special section called Technology Focus. Here are some of the technologies featured in the December issue focus on Data Acquisition.

Panoramic Video Patent Portfolio. Ten issued US patents for sale. Several U.S. applications: Computer Graphics Processing and Selective Visual Display Systems, Television, and Optics. Watermarking, Cryptography & Anti-Piracy Patent Portfolio. Eleven issued US patents for sale. Several U.S. applications: Electrical...

The world's most powerful medical magnetic resonance imaging (MRI) machine at the University of Illinois at Chicago has passed safety tests and will soon offer doctors a real-time view of biological processes in the human brain. The MRI, called the 9.4 Tesla (9.4T), will allow physicians to observe metabolic processes in real...

Science, technology, engineering, and math (STEM) courses often employ graphs, diagrams, and figures, putting students with visual disabilities at a significant disadvantage. The company Livescribe has created a smartpen and paper technology that aims to bring these subjects to life for blind students. Andy Van Schaack, a lecturer at...

Technology is required to enable real-time detection of defects during the welding process. This could be achieved by a system that monitors parameters during the welding process and then analyzes changes, ascertains the presence and location of a weld defect, and if possible, its nature. Potential solutions should be...

The University of California-Davis has licensed a new plug-in hybrid vehicle technology to Efficient Drivetrains Inc. (EDI) of Palo Alto, CA. EDI was founded in 2006 to commercialize the technology brought about by decades of work by Andy Frank, professor of mechanical and aeronautical engineering at UC Davis. Unlike hybrid-electric...

Researchers at Chalmers have succeeded in combining a receiver for high frequencies with an antenna on a small chip. Measuring just a few square millimeters, the receiver integrates an antenna, low-noise amplifier, and frequency converter, monolithically integrated on gallium arsenide. The receiver is designed to operate at...

The hassle of going through airport security and taking off shoes, watches, belts, and other items could be alleviated with a safe form of electro- magnetic radiation called T-rays, or terahertz radiation. Scientists at the U.S. Department of Energy's Argonne National Laboratory, along with collaborators in Turkey and Japan, have...
