A unique chamber tests pilotless aircraft for their ability to function at altitudes exceeding 67,000 ft. Engineers at Aurora Flight Sciences Corp. (Manassas, VA) designed, built, and operate the chamber, called the Ultra-High Altitude Test Facility. Aurora successfully tested its Perseus B drone in the 12- by 7-ft chamber. Ram air coolers, normally mounted under the Perseus wing and on the fuselage's side, were replaced with compact coolers in which liquid fluids cool the engine and turbos instead of the ram air. To simulate the low temperatures at high altitudes, a special low-temperature fluid with a freezing temperature of about -130C was pumped through the coolers.

When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
