...still-video cameras operate on the same basic principle. Light passes through a lens and strikes a flat electronic wafer called a charge-coupled device, which converts the image into electronic signals that are stored on a floppy disk in the same manner that a camcorder records the individual frames of a video movie. Once an image has been captured, it can be displayed on a TV, printed on paper or transmitted over telephone lines anywhere in the world. But whoever receives the images must have one of the cameras or other special equipment to view the pictures...
...with the introduction of Dexedrine's "tiny time capsules." Variations have included slowly dissolving wax-coated pills and small adhesive skin patches capable of delivering doses of medication. The new drug-delivery systems, based on advances in molecular biology, represent a dramatic improvement over their predecessors. Take the plastic wafer, about the size of a quarter, that can carry powerful drugs to brain-cancer victims. Researchers have known for some time that disks formed of chemical structures called polymers work well for dispensing small molecules like nitroglycerin, a pain reliever commonly used for heart patients. But the polymers seemed stubbornly...
Holograms, those silvery 3-D images that adorn 500 million credit cards, will - soon make an appearance on another product: designer clothing. Garments made by Italy's Gruppo GFT for European designers Valentino, Emanuel Ungaro and Claude Montana will arrive in stores next spring bearing wafer-thin holograms that are glued to labels inside the clothing. The images, virtually impossible to copy, will certify to shoppers and retailers that the designer pieces are authentic. Anyone who tries to rip out the label and transfer it to a counterfeit designer garment will ruin the hologram. Clothing manufacturers hope the holograms will...
...practical chip in 1958 and remains a major producer, is determined to help lead a U.S. counteroffensive. The company is rolling out devilishly tiny weapons, among them the world's first four-megabit chip, a supersophisticated semiconductor that can store more than 4 million bits of information on a wafer the size of a child's fingernail. Declares Norman Neureiter, a Texas Instruments vice president: "The U.S. semiconductor industry is not rolling over and dying...
...Button-cute, rapier-keen, wafer-thin and pauper-poor is S.J. Perelman . . . that he possesses the power to become invisible to finance companies . . . that he owns one of the rare mouths in which butter has never melted are legends treasured by every schoolboy...
