Yes, this is an interesting use of MEMS. I remember a few years ago, a company started up that captured the golf swings and baseball swings of stars and sold a system that tracked the user's swings against those of the stars. Cools application for MEMS. Not sure how successful that company was, but it was a clever idea.
Those are some pretty cool examples of MEMS in action on the sports field. Given a segment (and hopefully a growing one) of the population's focus on fitness and competitive sports, seems like a natural application and one that can really give athletes far more control over their training regimens.
Linear guides are one of the most important components required for the development of automated or computer-controlled equipment. Aluminum profile extrusions, used for these guides in machine design, can enable designed-in functional features.
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.
