Five years in development, Walt Disney's new interactive tour guide Pal Mickey operates off of an infrared wireless network that transmits information in order to help it triangulate its location and speak the appropriate audio message. (The receiver is in Mickey's nose.) The choice of infrared may seem surprising, given the need for line of sight and difficulties coping with direct sunlight (think crowded theme park in the Sunshine State). But Leslie Hartog, project manager for Pal Mickey, says that the entertainment giant is using a new, patent-pending outdoor infrared technology developed by its own engineers. "Even in bright sunlight, the technology is powerful enough that the toy will pick up the signals," explains Hartog. "Also, they bounce off of things like concrete and clothing." She says that Disney engineers actually preferred to use infrared over radio because of the greater accuracy and short transmission distances. The signals consist of mainly simple codes, with Pal Mickey having most of the smarts. In fact, it's programmed to speak some 700 different messages. As for delivering customized messages or using Pal Mickey to perform true traffic control in the park, though, Product Developer Kyle Poor says that's not in the plans—just yet.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
