Liquid crystal displays are manufactured on flat rigid substrates where the liquid crystals position between pixel electrodes and counter-electrodes. Flat is important, because bending produces unequal distances between electrodes. This difference results in color irregularities. Omron Corp.'s Material Development Department (part of the Electronic Components Business Company) is challenging the production limitation. Using a vacuum impregnation technique, Omron has demonstrated the ability to insert liquid crystals into a polymer film consisting of approximately 0.5-micron diameter spherical polyacrylate particles. Because the polymer network is finer than than conventional self-supported polymer/liquid crystal composite film, it allows a uniform color across a display whether the display is bent or not. Other potential applications for this capability include light-diffusion film, reflection film, and ink jet printing paper. For further details, contact Christopher_udell@omron.co.jp.
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.
