A Japanese company by the name of Takanoha has come up with a tiny gadget that prevents you from falling asleep. Putting the Nap Alarm behind your ear, the gadget vibrates once it detects that you are falling asleep. It measures the speed of head movements in order to determine whether or not the user is falling asleep. Just think of all those times you stayed up all night cramming for an exam—or, at least you planned on staying up. With the Nap Alarm, waking up 15 minutes before said exam may be a thing of the past, though falling asleep while driving is another matter entirely. (Hint: Find a place to stop, pull over. Problem solved.)
