Planning to fly on United or Continental at any point over the next few years? Then it looks like your odds of having in-flight WiFi will be getting increasingly better. United Continental Holdings announced today that it's signed an agreement with Panasonic Avionics Corporation to bring satellite-based WiFi connectivity to more than 300 of its aircraft beginning in mid-2012. Those aircraft will include Airbus 319 and 320 and Boeing 747, 757, 767, 777 and 787, and the company says it expects its entire mainline fleet to be covered by 2015. No specific word on any additional content or services that will come with it (or a cost, for that matter), but the company promises that the system will "enable wireless streaming of video content."

The idea of cars preventing accidents before they happen isn't novel, but at the end of the day, collision detection systems are only as smart as the information being fed to them. That's the ethos behind Continental's new stereo camera system, which spots people, pets, and other objects in a vehicle's path, and measures their height, distance from the vehicle, and how they might be moving. This rig, which will be just another part of Continental's ContiGuard safety system, uses the difference in the lenses' optical paths to make these calculations -- so long as those obstacles are 20 to 30 meters (66 to 98 feet) away. The company also says the cameras are sharp enough to detect partially obscured objects, and claims accuracy within 20 to 30 centimeters (8 to 12 inches). No word on when it will be ready to ship seeing cars, though if the press release is any indication, German drivers are likely to get their test drive first.
