    Public transportation has its own drawbacks: Buses and trains don't start at your home and don't end at your destination, nor do they leave just when you'd like or even guarantee you a seat. To get the best of both worlds, we could teach our cars to work together, as closely grouped cyclists do in a peloton. The lead car could be entrusted to a professional driver to whom the other drivers would of course each pay a small fee; all the other cars would follow it automatically. The cars would all use networked communications coupled with the optical or electromagnetic sensors already installed in some luxury cars to avoid head-on collision, stay in the proper lane, and brake in case of emergency. These systems have been developed at great expense to provide active safety, as distinguished from the passive kind afforded by seat belts. But this investment, having been made, can now be exploited for other things-like allowing you to relax and read the paper. If only we'd let them. Active systems are improving at a splendid rate. Adaptive cruise control, for example, maintains a car's speed while using radar or lidar to keep a safe distance from the car in front of it, thus automating much of the braking and accelerating. The latest generation of this system can follow a lead car from highway speed to a stop and then resume automatically when that car drives away. Soon the system will get additional data from vision sensors and digitized maps and additional support for the steering, allowing it to slow down on curves. View full abstract»

  • Sports: 3-D TV's toughest challenge

    If you're one of the 24 million or so people around the world who purchased a 3-D television in 2011-or the 42 million doing so this year-you might know what it takes to watch 3-D on your home television: a pair of 3-D glasses. But you likely haven't thought much about what it takes to produce the 3-D spectacle that comes to life in your living room. More cameras, or at least more lenses, you might think, and that's probably about it. View full abstract»

  • How RCA Lost the LC D

    In September 1967, Richard Klein and his boss, Lawrence Murray, traveled to RCA's central research facility in Princeton, N.J. It was a familiar trip for Klein, an associate engineer at the company's semiconductor division in nearby Somerville, whose work with light-emitting diodes kept him in close touch with solid-state researchers in Princeton. On this occasion, though, Murray assured him he was going to see something new. Sure enough, upon arriving in Princeton, Klein and Murray were escorted to a room where electrical engineer George Heilmeier presented them with a seemingly ordinary piece of glass attached to a power supply. Then Heilmeier flipped a switch, and a familiar black-and-white image suddenly appeared on the previously transparent square. "It was a TV test pattern," Klein recalled. "The thing pops up, and I almost fell over!" View full abstract»

  • Overclock My Satellite

    The Draper group teamed up with engineers at the Naval Postgraduate School, in Monterey, Calif. And in 2010, we carried out our promise to make the NASA observation satellite scan the sky faster than even its mission controllers thought possible. By operating spacecraft beyond their purported limits, we can extend their life and usefulness without installing new hardware and driving up costs. So how do we achieve this clever hack? Ultimately, we overclock a satellite by uploading a set of precise steering instructions from the ground to its onboard flight computer, essentially overriding its automated route. But that's the easy part. The real challenge is figuring out what those instructions should be, which requires solving mathematical puzzles known as optimal control problems. View full abstract»
