This week's question concerns the wonders and the woes of the American auto industry. With falling sales, the somewhat controversial "cash for clunkers" program, and the spate of bailouts that occurred last year for Detroit's "big three", the industry seems to be due for some...

A method of determining the radio refractivity of the atmosphere as a function of altitude involves processing of data acquired by airborne or mountain-top Global Positioning System (GPS) receivers from particular GPS satellites as those satellites rise above or fall below the horizon....

Another day at MD&M West has come and gone, and I'm continuing to see a lot of focus on miniaturization -- which makes sense, considering the multitude of medical applications that could benefit from compact yet efficient devices.

The SQUIGGLE motor from New Scale Technologies measures 2.8 x 2.8 x 6 mm....

Day one at the Medical Design & Manufacturing (MD&M) West show in Anaheim, CA was bustling with energy. Nearly everyone I spoke with said that they had found themselves happily busy throughout the day.

One nice part about meeting people at trade shows is that you might come across information you...

This week's question concerns a recent Forbes/AP story that reported on the nominees for the 2010 Nobel Peace Prize. These include a Russian human rights group, a Chinese dissident, and, believe it or not, the Internet. Proposed by the Italian version of Wired magazine, which...

Day two at SolidWorks World, the worldwide event for SolidWorks users, drew a record crowd. And this time it wasn’t because of the sunny Southern California weather. It was because the special guest speaker happened to be James Cameron, who just this morning was nominated for Best Director and Best Picture Academy...

This week’s question concerns the much-anticipated unveiling of the Apple iPad tablet computer/book reader/music, movie, and video player. At $499, Apple touts the device as a bridge between smartphones and laptops. Tech critics say it’s nothing more than a big iPhone.

A laser tracker (LT) is an important coordinate metrology tool that uses laser interferometry to determine precise distances to objects, points, or surfaces defined by an optical reference, such as a retroreflector. A retroreflector is a precision optic consisting of three orthogonal...

A compact, reliable controller for an electrically erasable, programmable readonly memory (EEPROM) has been developed specifically for a space-flight application. The design may be adaptable to other applications in which there are requirements for reliability in general and, in particular, for prevention of...

Solid-state frequency multipliers are used to produce tunable broadband sources at millimeter and submillimeter wavelengths. The maximum power produced by a single chip is limited by the electrical breakdown of the semiconductor and by the thermal management properties of the chip. The solution is to...

A method is provided for a radiationhardened (rad-hard) solid-state drive for space mission memory applications by combining rad-hard and commercial offthe- shelf (COTS) non-volatile memories (NVMs) into a hybrid architecture. The architecture is controlled by a rad-hard ASIC (application specific integrated...

High-speed, low-power, reconfigurable electronic hardware has been developed to implement ICER-3D, an algorithm for compressing hyperspectral-image data. The algorithm and parts thereof have been the topics of several NASA Tech Briefs articles, including “Context Modeler for...
