Another Beer Please 333
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.

Somebody would eventually pull up behind me and order. I would get whatever it was they ordered. If it was a big family, I would simply say I got trapped in the line and pass on thru, but if it was another single, chances are he ordered something simple too.. so I would just take it as if nothing happened pay for it, then pull around and park in the lot and watch all the confusion at all the subsequent orders being all out of sync.
Another funny thing is a lot of those order-taker panels were actually little two-way radios. With a strong local mobile rig, you could "capture" the carrier and make do like the restaurant. It was hilarious making do like the order-taker and playing with the customers.

Speaking as a former waiter, I know that a good deal of a waiter's time is taken up by simply checking on fluid levels. And that some people will have a full glass of beer/water/whatever for 10 minutes, but then drain the entire glass in 60 seconds. Quite difficult to time that refill.
If the waiter no longer had to constantly monitor drinks, it would free them up to handle more customers and/or provide better service.

Inductive coupling. Those PIC chips don't require much power at ALL to run! Like in the microamp region.

The data could be easily be transmitted by selectively loading the coil in a serial fashion. Th
Re:Inductive coupling (Score:4, Informative)
Read the article; it's far more ingenious than that. The coil is just feed into two PIC inputs, and the PIC's static-protection diodes do the rectification. A zener and a cap across the power pins complete the power supply.
It gets better. They use the clock pin as one of those inputs. Thus the chip is clocked by the received RF. And by briefing switching the other input to an output, they communicate pulses back to the sender. (That right -- no separate RFID chip, the PIC does all the sending as well as the sensing.)
Speaking of sensing, it gets even better. The capacitance measurement used to determine the fluid level is done by switiching two other input/output pins and a fixed capacitor to create a charge pump measurement. By counting the number of times a charge on the fluid-measuring capacitance has to be transfered to the fixed capacitor to bring it up to a logic level, they measure picofarad differences corresponding to changing fluid levels easily.
An utterly amazing bit of minimalist engineering!
