The dual-hinge operating mechanism in Motorola's PEBL mobile phone is made with injection molded 17.4 PH stainless steel to a density of 7.6 g/cm³. The innovative design positions the clamshell cover so that it slides down and flips open in one movement. The flip slider and hinge barrel are made by Advanced Materials Technologies Pty Ltd. of Singapore. According to the molder, the MIM process allows a very complex thin wall, overhanging structures and three-dimensional design. Both parts are coined, machined, polished and plated. It's estimated that it would have cost five times more to machine these parts. They won the grand prize in the electrical/electronic components category of the 2006 Powder Metallurgy Design Awards competition sponsored by the Metal Powder Industries Federation.

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.
