The Eastman Kodak Company and Sanyo Electric Co. Ltd. have formed a joint venture for manufacturing organic light-emitting diodes (OLEDs). Unlike a discrete LED which has crystalline origins, an OLED is a film-based emitter of light. An OLED display is self-luminous, so it does not require a backlight, weighs less than half of its LCD counterpart, and uses less power. It is also easily patterned for producing flat panel displays. The new technology has thin layers of individual carbon-based elements that emit light when electric current passes through them. A 2.5-inch (measured diagonally) OEL display has 190,000 pixels. Each element or pixel is independently turned on or off, creating multiple colors and fluid, smooth-edged images on the display. And the OLED display won't fade out when the viewer moves from side to side because the viewing angle is 160 deg. The display is readable in bright sunlight and total darkness. The two companies are beginning with a pilot facility this year and graduating to full production in 2003. The displays are designed for use in telephones, cameras, personal digital assistants, and portable entertainment machines. Visit www.kodak.com/US/en/corp/infoImaging/devices_flatPanel.shtml.
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.
