Million Dollar Ideas: Thinking Beer Mat

[ironman]

A beer mat that calls for a refill when the pint is almost empty has been invented by scientists in Germany. The electronic beer mat was created by computer scientists Andreas Butz of the University of Munich and Michael Schmitz of Saarland University. Beneath the cardboard surface is a small, flat baseplate which conceals pressure and acceleration sensors that react to the weight of the glass and the position and movement of the coasters.
