Spiralock Fasteners Safeguard Reliability for Medical Lasers and Implants

Failure is not an option when it comes to medical equipment. From critical or sensitive devices like lasers, MRI scanners, knee joints, and implantable pacemakers to instruments as straightforward as stethoscopes, when life is at stake, medical equipment must be reliable.

Laser Tracker Ensures Accurate Alignment of Ares I Components

FARO® Laser Tracker FARO Technologies Lake Mary, FL 800-736-0234 www.faro.comMaking 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.comNASA’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 By replacing multiple, outdated silos, NASA Ames has freed more than 1,400 square feet of valuable data center floor space.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.

Mass Flow Controllers Ensure Astronauts Have Medical Fluids On Demand

Quantim Coriolis mass flow controller Brooks Instrument Hatfield, PA 215-362-3527 www.brooksinstrument.comTransporting medical fluids that are manufactured on Earth into space is expensive and logistically challenging, so researchers at NASA’s Johnson Space Center sought a way to manufacture medical fluids in space. The Quantim Coriolis mass flow controllers from Brooks Instrument were chosen by NASA contractor ZIN Technologies for measuring water flow through a purification system to a standard IV bag that was prefilled with salt crystals and a magnetic lab stirrer. The Quantim devices are making their way into space to ensure that astronauts have medical fluids on demand for emergency needs.
