I remember seeing this on an episode of ‘Hey, Spring of Trivia‘ not all that long ago. There is was being used by Japan Rail to wake up their conductors at the station so they wouldn’t miss their shifts. The idea is that when the alarm sounds and air bag inflates and will wake even the most sound of sleeper. When you fist see this you thing it has to be a ‘Chindogu‘, or a an invention that has no real utility. Nope, it’s a real product that you can buy for your loved one or kid that is always late for the bus.
