Another Beer Please

Posted by michael on from the brooklyn-lager dept.

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.

  1. So what happens when... by sTavvy · · Score: 5, Insightful

    You don't want another drink, but your glass/table has ordered you another one, and teh waiter brings it over???
    and then proceeds to add the drink to the bill even though you didn't drink it, but you did order it.?

      Because people are FUCKING STUPID. Arbys and Taco Bell have both tried this, and people can't figure it out. "Duh... I pushed taco and said my order was done, now it says to pay the cashier?? what do I do???"

  2. Responsible Service of Alcohol by sTavvy · · Score: 5, Insightful

    Also kind of throws the "Responsible service Of Alcohol" policy that we have in Australia.
    How is the glass going to know how drunk the person is, and if they should be seerved any more alcohol?
