Top official describes DARPA real-time space awareness efforts

The Defense Advanced Research Projects Agency (DARPA) has transferred to the Air Force ownership of a revolutionary space surveillance telescope, and the agency is working on other real-time technologies to improve space situational awareness, including not just tracking satellites but debris of all kinds, natural and manmade.

OEMs: How to protect home devices and appliances from cyber attack
In July 2014, HP Labs did a study of 10 popular IoT (Internet of Things) devices and found security was shockingly bad. The researchers studied the devices, looking at end-to-end security capabilities including privacy protection, authorization, encryption, user interface protection, and code security. They found 70 percent of the devices had at least one major vulnerability. David West, Engineering Director at Icon Labs, runs through a checklist for OEMs to shore up IoT device security for their customers.

Researchers demonstrate how to make better aluminum casts -- inside and out
Industrial aluminum slabs are typically produced by blending small amounts of copper or manganese in a reservoir of molten aluminum that is rapidly cooled, a process known as direct-chill casting. Variations in the way these elements solidify can yield uneven results that weaken the final product, with castings sometimes ending on the scrap heap. Controlling the distribution of strengthening elements to aluminum throughout a casting is thus key to reducing waste and improving product reliability.

How special pink paint provides NASA with pressure pictures

They say you show your true colors when you're under pressure. Turns out the old saying works for models being tested in wind tunnels as well, specifically those coated with a unique pressure-sensitive paint (PSP) that NASA engineers have used for more than 25 years.

Mike Likes: New innovative way to take up tolerances!
Smalley Linear Springs are a continuous wave-formed (marcelled) wire length produced from spring-tempered materials. They act as a load-bearing device, having approximately the same load/deflection characteristics as a wave spring. Linear Springs are now available as a standard part in carbon and stainless steel, with over 200 sizes.

Engineer's Toolbox:
World's smallest production V8 optimized with precision honing

Gary Conley's 30-year quest to manufacture a true production V8 engine in quarter-scale almost went up in smoke twice: once in 2001 when a foundry fire claimed all his critical molds, and later when oil smoke proved a stubborn problem during run-offs of the engine. Conley overcame the first setback with years of sheer determination. The second issue required a Sunnen MB 1660 honing machine, abrasives, and some Sunnen know-how.

Chairless exoskeleton solves long-standing problem
The Chairless Chair is a new innovation for relieving strain and fatigue from excessive standing during long work shifts. The entire construct is lightweight, easy to put on, and hardly noticeable when walking. By operating a switch on the strap, the flexible construct turns into a stable seat. Two small DC motors activate a stop valve in the hydraulic elements of the shock absorbers, locking the support into the seated position.

Fun: World's largest Rube Goldberg machine lights up Christmas tree
To make the act of switching on the town’s Christmas tree lights even more exciting, Latvian e-commerce company Scandiweb constructed the world’s Largest Rube Goldberg contraption for the people of Riga. Recognized by Guinness World Records, the feat is also, arguably, the most elaborate way anyone has invented to turn on some festive lights. The chain reaction consisted of 412 individual mechanical steps. It took two months to construct.

Wheels: Stanford researchers show Swedish airbag bike helmets hold promise
David Camarillo, whose Stanford lab works on understanding and preventing concussion, decided to test a new type of inflatable helmet that is available in some European countries. While he doesn’t doubt that wearing a helmet is better than no helmet at all, Camarillo thinks that traditional helmets don’t protect riders as well as they could.
