Wafer Level Camera Technology

Film cameras were traditionally manufactured by discrete assembly, which means each component was fabricated as an individual item, tested if necessary, and then assembled into the final working product. The advent of solid state imaging did little to change this approach. The film was merely replaced by a light-sensitive electronic component. The only significant change was that the mechanical shutter was rendered obsolete and its action generated electronically within the imager die.

Dr. Scott Barthelmy, Research Scientist, Laboratory for High Energy Astrophysics, Goddard Space Flight Center, Greenbelt, MD

Dr. Scott Barthelmy is the principal investigator for the Burst Alert Telescope (BAT), a sophisticated instrument that detects and precisely locates elusive gamma-ray bursts in the universe. Developed as part of NASA’s Swift mission, the instrument technology is now being considered for a variety of homeland security applications because of its ability to pinpoint and identify nuclear materials – both legal and illegal – in transit or storage. Dr. Barthelmy also created the Gamma-Ray Bursts Coordinates Network (GCN) to distribute data collected on gamma-ray bursts to researchers throughout the world in real time.

Laser Tracker Ensures Accurate Alignment of Ares I Components

FARO® Laser Tracker FARO Technologies Lake Mary, FL 800-736-0234 www.faro.com

Making its first flights to the International Space Station by the middle of the next decade, the Orion crew exploration vehicle is part of the Constellation Program, which will send human explorers back to the Moon, and then to Mars and other destinations in the solar system. Future astronauts will ride into orbit on Ares I, Orion’s launch vehicle, which uses a single, five-segment solid rocket booster. NASA’s first test flight, called Ares I-X, will provide NASA with an early opportunity to test and prove the hardware, facilities, and ground operations associated with the Ares I.

Tape Backup Systems Help NASA Archive Enterprise Data

Spectra® T950 tape libraries Spectra Logic Federal Boulder, CO 303-449-6400 www.spectralogic.com

NASA’s Ames Research Center in Moffett Field, CA, installed two Spectra® T950 tape libraries with LTO-4 drives and media, which together offer approximately 20,000 data storage slots and up to 32 petabytes of storage capacity, with data compression. By replacing multiple, outdated silos, NASA Ames has freed more than 1,400 square feet of valuable data center floor space.

The Physics of Failure: Predicting Reliability in Electronic Components

A lot has been written about Moore’s Law and the potential limitations of semiconductor design and manufacturing in the future. Can we really continue to double the number of transistors on a given-sized die every eighteen months? For the last 30 years, Moore’s Law has held, but, we may be seeing the real limitations to future semiconductor development and to Moore’s Law — severely shortened operational lifetimes of advanced chips. That, in turn, creates massive reliability problems for critical embedded systems in the future.

Measuring the Color and Appearance of Special-Effect Paint

Manufacturers that design, formulate and apply coatings have struggled for years to find a rigorous and easy-to-use method that reliably measures the color and appearance of special-effect paints. Companies tried to relate measurements taken with handheld spectrophotometers that collect colorimetric data from several in-plane angles to events that occurred in production processes, but these instruments, by their nature, could not collect the essential data points to yield reliable results. Other companies have tried to skirt the problem by creating a coarseness index or “sparkle” metric that relies on photographic images taken in-plane, but this method is easily confused and insufficient for rigorous analysis.

NASA Celebrates Apollo’s 40th Anniversary

Forty years ago this month, on July 20, 1969, Apollo 11 commander Neil Armstrong stepped out of the lunar module and took “one small step” in the Sea of Tranquility, calling it “a giant leap for mankind.”

Designing the First Fully Sustainable Block in the U.S.

In the near future, a crumbling parking lot in downtown Dallas, Texas will be the location of the first fully sustainable, urban square block in the United States. Re:Vision Dallas is the sixth competition in a series from the San Francisco, California-based organization, Urban Re:Vision – a group of people focused on changing the urban landscape by re-imagining the components which make up a city block.

NASA Geostationary Coastal and Air Pollution Monitoring

The Geostationary Coastal and Air Pollution Events (GEO-CAPE) mission has been recommended for launch in the 2013-2016 time frame by the National Research Council. The mission’s purpose is to gather science that identifies human versus natural sources of aerosols and ozone precursors, tracks air pollution transport, and studies the dynamics of coastal ecosystems, river plumes, and tidal fronts.

Test Control and Measurement Software

Jacobs Technology Group, Tullahoma, TN, offers Test SLATE test control and measurement software that enables users to create a data acquisition and test automation program using point-and-click Windows-based graphical tools on any PC. Data is visually presented in the style and format chosen by the user, and the display format and content may be modified on the fly using drag-and-drop graphics. It is composed of off-the-shelf components such as National Instruments’ LabVIEW and Microsoft’s SQL Server Express. The software supervises all control and measurement activities in automated testing using solutions as simple as a single PC, to multi-system networked architectures. The program coordinates control and measurement functions from multiple vendors’ hardware, and can take hundreds of measurements simultaneously. The system is designed for applications in aerospace, automotive, and manufacturing, but is adaptable to environmental test and measurement applications, automating and collecting data for conditions such as wind, moisture, speed, temperature, and pressure.
