Non-Contact Seal Sensor
When vacuum seals can't handle the strict tolerances required by high tech vacuum systems, the job goes to ferro-fluid based seals. Measuring the actual performance of these seals can often add unwanted drag to the seal mechanism. A non-contact measurement technique using radio waves rather than physical touch provided the solution.

Money Saving Cordless Tools
That's the story from the National Council on Compensation Insurance. The report claims that cordless tools reduce trips, falls, and entanglement related injuries. Compared with traditional corded tools, cordless tools are initially more expensive to buy. However, the report indicates that contractors and employees can benefit in the long run.

Metal Mystery Revealed
Fifty years ago, scientists discovered that tiny metal structures called "tin whiskers" exhibited amazing strength, but were baffled by the reason for this phenomenon. Recent research at the Materials Sciences Division of DOE's Lawrence Berkeley National Laboratory reveals the highly technical answer, mechanical annealing reduces dislocation density.

Beauty More Than Skin Deep
Cars today are partially made of discarded soft-drink bottles and plant-based material used in seats and upholstery. Besides fuel, oil-based products are used to create materials for thousand of automotive parts. Virtually indistinguishable recycled or plant-based substitutes can improve mileage and improve emissions. Would you support eco/agri autos?

Recycling Throw Away Technology
Many parts of the world have become used to trashing perfectly good products for the latest and greatest versions flooding the marketplace. But most mechanical components don't simply disappear, and so man has turned to recycling. But let's not forget the craftsmen in countries that still can't afford to purchase new electronics and rely on reuse. Perhaps we could re-learn some forgotten lessons from Egyptian recyclers who take a completely different approach.
