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.
United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
The new small-form-factor EZ-BLE PRoC (Programmable Radio on Chip) module is a derivative of the existing PRoC BLE Programmable Radio-on-Chip solution. The EZ-BLE PRoC module integrates the programmability and ARM Cortex-M0 core of the PRoC BLE, two crystals, an onboard chip antenna, a metal shield, and passive components.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
