Whacking protective helmets until they break might seem like a fun diversion for charged up kids, but it’s serious business at the Snell Memorial Foundation, which certifies the safety of all kinds of helmets. Gathering analog signals is critical for all real-world tests, particularly those that happen quickly. Snell uses National Instruments’ CompactDAQ modules to gather data generated during the 36 times helmets are dropped onto steel anvils. If the system registers more than 300 Gs inside the helmet, it fails the tests. The Snell Foundation was formed in the ‘50s after auto racer Peter Snell died from head injuries in a slow rollover crash.

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.
