I’m in a state of fascination now that I’ve had time to peruse the Arcteryx patent for a battery operated fan-filled avalanche airbag pack. The patent includes juicy tidbits such as the idea of being able to fill the bags up to 50 times between charges, and including a motion switch that could activate the system without user intervention (with cutout, of course, in case you want to do inverted sorts of things on purpose). Perhaps most importantly, the system will weigh significantly less than compressed gas units and be easy for TSA to deal with (though the powerful lithium battery is probably subject to some sort of restriction). View the PDF here, or just check out the images below. Discuss? (Click images to enlarge slightly for more legibility, or peruse the PDF linked above.)
