...that snaps taken with a $500 digital camera often aren't as sharp as those from a $20 disposable? Because unlike the light-sensitive chemicals in ordinary analog film, each sensor on a digital chip saves only one-third of the color data it receives--either red, green or blue, but not all three at once. With the new Foveon X3 technology, however, three sensors are stacked on top of one another, so that each pixel absorbs the full color spectrum. Result: a 3.5-megapixel camera using Foveon technology will produce images as clear as today's 7 MP models...
That's what Dr. Weiss is after. The idea is to heat up the underlying dermis, stimulating fibroblast cells to produce collagen, which pushes out fine wrinkles and scars. "This temperature sensor is monitoring things," says Weiss, 49, as he points to a fail-safe device on the laser. "If the temperature rises too high in the skin, it won't let you do another pulse...
When Holgersen wants to pick up a glass, he moves his right shoulder upward. This movement sends an electrical signal from the position sensor, which is worn under his clothing, to the stimulator in his chest, which amplifies it and passes it along to the appropriate muscles in his arm and hand. In response, the muscles contract and his left hand closes. When he wants to release the glass, he moves his right shoulder downward and his left hand opens...
...most innovative musical toy at the Toy Fair this year is Neurosmith's Musini ($69.99, ages 3 and older, due out in September). Musini is built around a motion sensor that picks up vibrations from the surrounding room. Put it on the floor, and when a toddler stamps a foot or knocks on a wall, Musini composes music on the fly in time with the kid's movements. The room itself becomes a musical instrument, one that never plays the same song twice. Note: Musini is not compatible with Hummel figurine collections...
...system tells frantic business travelers exactly where the spots are. Electronic signs announce the available spaces in each row. As you're driving by, just watch for the brightly lighted LED--a green arrow if the spot is vacant, a red X if not. The secret is a sensor that detects occupancy. Used in parking lots from Barcelona to Seoul, Smart Park is now a welcome addition to lots at Baltimore-Washington International and Jacksonville International airports. Watch for more...
