Fans of more extreme sports will probably be stoked to hear that Apple just might be developing a device with them in mind. Apple Insider's discovered a recent patent filing that could possibly signal the development of a monitoring device (much like Nike+) which can detect, track, and display a visual and quantitative measure, for instance, of a skier's speed and air time. The device looks like it would contain one or more loft sensors (in one photo it is shown installed in a snowboard) and a microprocessor subsystem to determine loft time. There are of course, no guarantees that a product like this will ever see the light of day, but we sure hope so: runner favoritism must end. One more page of the filing after the break.
