The Nora system consists of a smooth "pebble-shaped" wireless mic that sits on your bedside table, a mini pump that's located beneath the bed, and a hose-connected flat rectangular padded bladder that's inserted between your pillow and pillow case.
When the mic detects the sound of snoring, it activates the pump. It, in turn, quietly inflates the bladder. This causes your head to subtly change position, which stimulates and thus tightens your upper throat muscles – it is these muscles that typically cause snoring when they relax, collapse and constrict your airways.
As a result of those muscles firming back up, you reportedly stop snoring, without awakening.
Of course, Nora still can't stop you from starting to snore in the first place. If you're curious to see how you're doing on that front, a companion iOS app will show you how you slept (and how noisy you were) over the course of the previous night, and how that changes over time.
Nora is currently the subject of a Kickstarter campaign, where a pledge of US$179 will get you a system – assuming it reaches production. The planned retail price is $299.
Hammacher Schlemmer's existing Snore Activated Nudging Pillow works on a principle similar to that of Nora, although it incorporates everything into one product-specific pillow ... so you can't just keep using your favorite pillow, or whichever one is handy.
