Stein over mat-ter
From:
September 29, 2005

BERLIN: German inventors have devised an interactive beer mat that can tell the barman when it's time for a refill.

The device comprises a small, flat base plate with a traditional cardboard beer mat on top. The plate conceals sensors that react to the weight of the glass, or stein, and movement of the beer mat.

The sensors relay the data to a computer at the bar. Its inventors believe the gadget could also be used as a voting device in pub games

Kinda neat.

I've heard of a similar device except it used some laser/light to measure the density of the beer or the refraction to indicate how much beer is left. I believe that the Canon ink cartridges kind of do the same thing to indicate it's low on ink.

I've never had a problem communicating to the bartender when I need another :D.

Hey, I have an idea, make the beer glasses out of glass, so the bartender can just see how low you are...

Oh, wait... :rolleyes:
