Next-Generation Electronics Innovations for NASA’s Space and Commercial Future

In 1964, NASA’s Electronics Research Center (ERC) opened in Massachusetts, serving to develop the space agency’s in-house expertise in electronics during the Apollo era. The center’s accomplishments include development of a high-frequency (30-GHz) oscillator, a miniaturized tunnel-diode transducer, and a transistor more tolerant of space radiation. Another development was in the area of holography. At the ERC, holography was “used for data storage, and has permitted a remarkable degree of data compression in the storing of star patterns.”

Successful Test Management For Systems Engineers

Designing a reliable test strategy requires broad, strategic thinking. The goal of verification is to ensure you release a best-quality system that meets customer expectations as documented in your early design concept and requirements gathering phases. To maximize the value of your test process, test your product objectives early.

Delivering Roadworthy Designs: Automotive Electronics Circuit Protection Overview, Applications & Standards

Today’s automotive designs include nearly 100 microprocessors; that number is expected to double in five years. From in-dash displays to connected technologies and safety systems, all onboard electronics require circuit protection to maintain reliability. The major sources of electrical hazards in automotive systems are electrostatic discharge (ESD), switching loads in power electronics circuits, and lightning. Overcoming transient surges that can harm the vehicle’s electronics, whether under the hood or in the cabin, is one of the biggest obstacles of system design.

How to Avoid PCB Re-spins when IC’s Change or are Obsoleted

Working with printed circuit boards (PCBs) for sophisticated military, aerospace, or medical systems can be a frustrating – and expensive – exercise, particularly when the customer requests “a simple upgrade” or modification after the boards have been made or after deployment. Thanks to Murphy’s Law, these “simple upgrades” are never as simple as they should be. Aries has developed a unique solution that can save you from having to re-spin your PCB due to IC obsolescence or package change.

2015 Create the Future Design Contest: Electronics Category Winner

Real-Time Fiber Optic Sensing System Lance Richards NASA Armstrong Flight Research Center Edwards, CA “The entire team of researchers who have dedicated years to the development of the FOSS technology is honored to receive this award. Since the beginning of our work, we wanted to create a better sensing system, making structural monitoring more comprehensive and lightweight. As we realized how broadly applicable FOSS was, we were inspired to keep innovating.“ A team at NASA Armstrong has developed fiber optic sensing system (FOSS) technology that represents a major breakthrough in high-speed operational monitoring and sensing. Driven by ultra-efficient algorithms, FOSS can be used to determine, in real time, a variety of critical parameters including strain, shape deformation, temperature, liquid level, and operational loads. This state-of-the-art sensor system delivers reliable measurements in the most demanding environments confronted by aerospace, automotive, and energy sectors. FOSS is ideal for monitoring the structural health of aircraft, buildings, and dams; improving the efficiency of turbines and industrial equipment; and detecting instabilities within tunnels and power plants.
