"How often have you, or someone you know, eschewed a bicycle helmet to look cool at the expense of safety? \nWell, gamble with a traumatic brain injury no more. Two Swedish inventors created an invisible helmet called H\u00F6vding, and it doesn't involving using any Harry Potter invisibility cloak magic, or even plastic. The helmet is actually a thick collar \u2014 like one you might see on a heavy winter jacket \u2014 with an airbag hood underneath that deploys should you get in an accident. \n\n\nIt uses rechargeable battery-powered accelerometers and gyroscopes to detect movement that resembles being in a bike crash and launches airbags around the wearer's head. \n\n\nWeighing 1.5 lbs. without the shell, the airbags are powered by a cold helium inflator located in a holder in the collar. Though similar to motorcycle helmets with inflators, this helmet is only for bicycles \u2014 not skateboards, mopeds, or skates, either. \nIf you're concerned with matching your helmet-collar to your outfit, you can buy coordinating shells that house the airbag. \n\n SEE ALSO: High-Tech Threads: Can Your Clothes Do This?\nThe helmet also contains a \"black box\" that records 10 seconds of data of the cyclists' movement before an accident. If you do get in a bike accident, H\u00F6vding asks that you send the black box in for their research purposes, but they'll give you a discount on the next helmet if you do so.\nAt a cost of about $600, that's an expensive safety measure. The helmet is only good for one use, so you'll have to replace it after it deploys. \nWould you buy a H\u00F6vding collar-helmet?
