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 Wavelet...

The high-speed ring bus at the Jet Propulsion Laboratory (JPL) allows for future growth trends in spacecraft seen with future scientific missions. This innovation constitutes an enhancement of the 1393 bus as documented in the Institute of Electrical and Electronics Engineers (IEEE) 1393-1999 standard for a spaceborne...

This week’s question concerns 3D TV. The recent success of 3D movies such as Avatar has added to an already-growing interest in 3D television and content. TV makers such as Sony, Samsung Electronics, LG Electronics, and Panasonic showed 3D ready televisions at the recent Consumer Electronics Show and expect to...

This week’s question concerns nuclear weapons. Diplomats from 65 countries are meeting at the United Nations Conference on Disarmament in Geneva this week to discuss beginning talks on a possible treaty that would stop nations from producing plutonium and highly enriched uranium...

Do the Russians know something we don’t? In the waning days of 2009, the head of Russia’s federal space agency, Dr. Anatoly Perminov, made huge headlines by telling a Russian radio station that their space agency was contemplating sending a mission to Apophis, an 885-foot (270-meter) asteroid first...

This week’s question concerns tablet computers. Apple Computer is strongly rumored to soon unveil a tablet computer able to play music and video, read E-books, and provide Internet access. Several PC makers, including Motorola and Hewlett-Packard, also demonstrated tablet computers at...

I mentioned in my last blog post I will travel to Anaheim in early February to attend several shows, notably the Pacific Design & Manufacturing Show and Medical Design & Manufacturing West. That means once again subjecting myself to the rigors of airport security - whipping out my photo ID, emptying my pockets...

As the holidays fade and the New Year unfolds, it’s back to business for most of us. For NASA Tech Briefs, that includes a bunch of trade shows and conferences our editors will attend over the next few months. One show I plan to attend is the Pacific Design & Manufacturing Show, taking place at the Anaheim Convention...
