"If you put lots of high-tech stuff on a soldier's helmet and the additional mass makes the helmet slide over the soldier's eyes when he dives into a fox hole, that's a problem," says Robert Playter, vice president of engineering at Boston Dynamics. "That's the kind of problem you want to uncover before the helmet makes its way to the battlefield." Boston Dynamics is developing software tools for virtual prototyping of next-generation soldier equipment that are part of Objective Force Warrior, the U.S. Army's new science and technology initiative to develop future soldier fighting systems. The company is using its Digital Biomechanics , which relies on robotic control and physics-based models, for providing human-simulation software that obeys the same laws of locomotion, balance, and loading as a person would in the physical world. Analysts at the Army's Soldier Systems Center in Natick, MA use Digital Biomechanics to assess the impact of prototype designs on soldier performance before building physical mock-ups and testing with soldiers. Virtual prototyping reduces the design cycle. "Instead a design cycle of a year or more, the goal is to get things done in months or weeks," says Playter. Prototyping tools the company will deliver to the Army in upcoming months include physics-based simulation of soldiers performing war-fighting tasks. "We proved the concept, now we are developing the product." For more information, go to www.bdi.com.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
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.
