Another Beer Please

jmichaelg writes "What do you get when you combine a glass, a PIC computer, two capacitors, a coil and a zener Diode? A wireless beer glass that signals your waiter when you need a refill. The circuit is an RFID transponder that measures the fluid level in a glass and transmits a globally unique ID coupled to the fluid level reading when queried by an antenna hidden in your table. The query provides enough power to drive the circuit so no batteries are needed. A technical paper describes the circuitry in the table and the glass." This hit the news over a year ago, but we didn't have the technical details.

Damn it. I had this idea YEARS AGO. Had I only written it down and filed, I could have lived the american dream and became stinky filthy rich by doing nothing :(

Think of an old diner, but in place of the jukebox at the end of every booth, you have a touchpad menu that lets you order everything right there whenever you are ready. If you need your waitor, the push of a button says "get your ass over here." You don't need drink sensors because if you buy a drink, you have a universal fountain right at your table, ready to refill water, soda, beer even!

How cool would that be?
