Wireless control system for dispensing beverages from a bottle
A pour spout, for attaching to a bottle, has a first wireless transceiver and a valve for selectively controlling flow of a beverage from the bottle. A server interface, adapted to be carried by a person who serves beverages, has a second wireless transceiver. A control unit is provided to wirelessly communicate with the second transceiver. In one mode, the pour spout transmits a spout identifier to the server interface, which responds by transmitting the spout identifier and a server identifier to the control unit. The control unit responds with a reply transmission causing the server interface to command the pour spout to open the valve. In another mode, a person selects a cocktail, that results in the control unit sending designations of a plurality of liquor ingredients to the server interface. The server interface controls dispensing each of the plurality of liquor ingredients.
1. A method for dispensing a beverage from a bottle comprising:
transmitting a dispensing authorization message wirelessly from a stationary control unit to a server interface that is being carried by a person who serves beverages;
responding to the dispensing authorization message by wirelessly transmitting a dispensing command from the server interface to a pour spout attached to the bottle, wherein the dispensing command designates a nominal pour time interval and further wherein the pour spout senses an angle to which the bottle is tilted and in response to the angle produces a first adjusted pour time interval from the nominal pour time interval; and
responding to the dispensing command by the pour spout opening a valve through which the beverage flows from the bottle and out of the pour spout for a period of time that is derived from the first adjusted pour time interval.
2. The method as recited in claim 1 wherein the pour spout senses a temperature and produces a second adjusted pour time interval from the first adjusted pour time interval; and opens the valve for a period of time that is derived based on the second adjusted pour time interval.
3. The method as recited in claim 1 further comprising occasionally operating the valve without dispensing the beverage in order to inhibit motion of the valve from sticking.
4. A method for dispensing a beverage from a bottle comprising:
(a) transmitting a spout identifier wirelessly from a pour spout attached to a bottle to a server interface that is being carried by a person;
(b) transmitting a request message wirelessly from the server interface to a stationary control unit, wherein the request message contains a server identifier unique to that server interface and the spout identifier;
(c) responding to the request message by wirelessly transmitting from the stationary control unit to the server interface a reply message that thereby authorizes beverage dispensing;
(d) responding to the reply message by wirelessly transmitting a dispensing command from the server interface to the pour spout; and
(e) responding to the dispensing command by the pour spout opening a valve through which the beverage flows from the bottle.
5. The method as recited in claim 4 further comprising prior to (a) determining a desire to dispense the beverage from the bottle by detecting motion of the bottle.
6. The method as recited in claim 4 wherein a spout identifier comprises designations of a brand of beverage, a type of beverage, and a volume capacity of the bottle.
7. The method as recited in claim 4 further comprising the server interface visually displaying a name of the beverage.
8. The method as recited in claim 4 wherein the dispensing command designates a nominal pour time interval; and the pour spout opens the valve for a period of time that is derived from the nominal pour time interval.
9. The method as recited in claim 8 wherein the pour spout responds to a value selected from the group consisting of: a temperature value, a bottle tilt angle value, and a liquor quantity value in the bottle to which the pour spout is attached and derives an adjusted pour time interval from the nominal pour time interval; and opens the valve for the adjusted pour time interval.
10. The method as recited in claim 4 further comprising prior to (a) determining a desire to dispense the beverage from the bottle by activating an input device by a person.
