No, sadly that's not a Proton Pack from Ghostbusters, but it's no less cool: behold the laser backpack developed by researchers from UC Berkeley (go Bears!). InventorSpot explains:
We’ll state right up front that the thing bears little resemblance to the slick units used in “Ghostbusters” or anything that a Star Wars fanboy or Star Trek fangirl dreamed up.
It’s ugly and misshapen – almost aggressively so – but the scientists at the University of California, Berkeley weren’t exactly going for looks.
Instead, they were going for an improvement in current laser mapping techniques, which right now can take anywhere from a few day up to a week or more, especially for an interior space with a great deal of surface variations, nooks, crannies, and things you should really have put away before your mom came over.
