Bill Jackson, Deputy Director, NASA Independent Verification and Validation Facility, Fairmont, WV

Bill Jackson Searching for defects amid several thousand lines of code in mission critical software, NASA’s Independent Verification and Validating Facility (IV&V) was open for business in 1994 as a safeguard against mission failure. Reporting to the Goddard Space Flight Center, the IV&V audits software across NASA (and other government agencies) dealing with several different projects concerning satellites and shuttle mission software. The current Deputy Director, Mr. Jackson was Acting Director of IV&V from January to October of 2006.

13-bit magnetic sensor

Renishaw, Hoffman Estates, IL, has introduced a 13-bit magnetic sensor for rotary and angular positioning control. Providing 8,192 counts per revolution, the sensors are available in chip, chip-on-board, and ready-to-mount packaged versions. The solid-state, non-contact design features an integrated circuit chip that senses the position of a separate two-pole permanent magnet. Suited for difficult environmental requirements, the sensors provide -40°C to 125°C operational temperature range, and shock and vibration resistance. Friction-less, low-inertia operation enables 0.3° positioning accuracy at speeds to 30,000 rpm. They are available in models providing absolute, incremental, analog, or digital outputs, as well as simultaneous SSI and incremental output. Chip and chip-on-board models allow the sensors to be integrated into machinery and equipment designs. Packaged versions enclose the chip and electronics in metal cases. Enclosed units are used in rugged applications and environments; fully encapsulated versions are waterproof.

NASA Studies Paper-Like Plastic for Space Electronics

On the right is an antenna array embedded on liquid crystal polymer (LCP); a large sheet of LCP is on the left. (Georgia Tech Photo: Gary Meek)NASA’s Earth Science Technology Office and the Georgia Institute of Technology (Georgia Tech) are evaluating a material called liquid crystal polymer (LCP) for electronics applications in space, as well as possible uses in consumer electronics. The ultra-thin, paper-like plastic can incorporate a variety of electronic circuits, while still molding to any shape. It also performs well in extreme temperatures and intense radiation found in space.
