Abstract

A beverage dispensing control and quantity monitoring system includes a transponder to transmit a signal from a control cap placed on a liquor bottle to a receiver system and then to a data processing device. The cap fits on the bottle and contains an electronic package which will meter an exact amount of beverage when tilted, thus controlling the amount poured. The cap also transmits to the receiver such data as the operator or bartender pouring the beverage, the type of beverage, the amount of beverage, and any other necessary data such as when the cap is removed from the bottle, when the battery therein is low, etc. This is accomplished using a plurality of data bits preprogrammed into each bottle cap which are serialized using a shift register. The serialized data gates the output of an LF oscillator. A separator HF signal transmitted from the vicinity of the bottlecap is mixed in a nonlinear device with the gated LF oscillator output and radiated to a remote receiver and data processing device.

setting re-programmable data switches disposed within a given bottle control cap for impressing therein data bits to identify that cap from others in a system of programmable control caps;

opening a valve in the control cap;

activating electronic circuitry disposed within the control cap that both serializes the data bits impressed therein and also transmits a radiated signal containing the serialized data bits;

serializing the data bits programmed into the control cap using the energized shift register;

passing both the serialized data bits and another output from the oscillator through an AND gate in the control cap;

gating through the AND gate pulses corresponding to the serialized data bits;
