...feel groggier some mornings than others? It may be because your alarm went off when you were in the middle of a deep sleep. The Sleeptracker watch solves this problem by waking you only when you are in a light sleep. Equipped with a built-in motion sensor, the watch can tell whether you are in a deep or a light slumber. (The more restless you are, the lighter your sleep.) To ensure an optimal waking time, allow a window of 20 minutes or so when it would be O.K. to get up. Then Sleeptracker's alarm will...
...giving them plenty of ways to gather information about their environment. Takao Someya, a researcher at the University of Tokyo, has created an electronic film-made up of bendable, shock-resistant transistors embedded in plastic-that can detect pressure and temperature. The sheet, known as a "large-area sensor array," is flexible enough to cover small objects and could give robots a sense of touch. Another potential use: smart carpet or furniture upholstery that can automatically adjust its temperature. Next Product: Goin' Coconuts...
...TUNE UP. Cleaning your clogged air filters improves mileage 10%, for a savings of 27¢ per gal. Fixing a faulty exhaust-pipe oxygen sensor, which monitors the fuel-to-air ratio in your engine, can save 40%, or $1.08 per gal. Properly pumping up tires can inflate mileage...
...Everio G series has many great features. If you drop a hard disk while it's spinning, there's a chance it'll go kaput. That's why JVC built a drop sensor into the camcorder. Whenever it senses itself plummeting downward, it shuts down completely, and in the blink of an eye. JVC's "Data Battery" relays information to the camcorder, so when you push the Info button, a screen comes up telling you how much hard drive space is left; push the button again and you learn exactly how much longer the battery will last. There's also...
...developing a night-system sensor that can see things a naked eye cannot. The system would automatically prevent a collision. Another system protects a car from spinning even after its emergency brakes are applied. In the future we can develop a sleep-and-drive-prevention system, whereby a device will tap the sleeper and wake him up. I want to make it happen quickly. My dream is a system that would pick up the danger of collision and save the driver or passenger from being [ejected] and suffering injuries--something like a net that rescues a person before collision because...
