Los Angeles —The figure in the picture is no dwarf. It's a technician at Boeing Satellite Systems (BSS), formerly Hughes Space and Communications Co. BSS is building the 12.25-m (40-ft) reflector designed for geostationary satellites used in regional mobile communications. Known as the Boeing GEM spacecraft, it transmits and receives signals from an L-band feed array, which forms a large number of small spot beams whose position can be adjusted as phone traffic warrants. Composite materials provide a 78-kg (170-lb) reflector that compresses into a 1.3-m (50-inch) diameter 3.8-m (150-inch) long package for launch. The first GEM spacecraft is the Thuraya-1 satellite, which will be part of a mobile satellite system including the Arab world, Indian subcontinent, Central Asia, and eastern Europe including Turkey.
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.
