Hermetic Feedthroughs Safeguard Mission-Critical Electronics

Experts specializing in electronics failure analysis can list a host of reasons for various malfunctions, but one of the most common causes is simple moisture. Because water and electronics do not mix well, several strategies exist to protect mission-critical components from moisture and condensation. One of the most successful methods of protecting key components from water hazards involves hermetically sealed electronics cavities—enabled by moisture-blocking component assemblies such as hermetic feedthrough technology.

Component Design with a Twist

Helixes in nature abound—from the formation of DNA, to the spiral of a seashell, to the tendril of a climbing vine. That is because the helical structure provides support for the curve through three-dimensional space. Taking a cue from nature, Fort Wayne Metals created its Helical Hollow Strand (HHS® Tube) with up to three layers to provide engineers with solutions to design problems that exceed the capabilities of conventional constructions.

Five-Fingered Robot Gets a Grip

Intricate tasks that require dexterous in-hand manipulation — rolling, pivoting, bending, and sensing friction — are a challenge for today's robots. A University of Washington team of computer scientists and engineers has built a robotic hand that performs dexterous manipulation and "learns" from its own experience. The five-fingered robot, for example, can spin a tube full of coffee beans without needing human direction.

Students' Decelerator Design Wins NASA's 'Big Idea' Challenge

Students from the University of Illinois at Urbana-Champaign took top honors in NASA’s first Breakthrough, Innovative and Game-changing (BIG) Idea Challenge. The challenge: To increase the lift-to-drag ratio on the Hypersonic Inflatable Aerodynamic Decelerator (HIAD) in ways that could potentially help NASA land heavier payloads. The HIAD inflatable device is designed to slow down a spacecraft upon atmospheric re-entry to Earth or other planets.
