"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.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
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.
