Monitoring beverage pours
Techniques for monitoring dispensed liquid include an intelligent spout that incorporates an IMU (Inertial Measurement Unit) for tracking its own orientation and movement in three-dimensional space. The spout has its own processor, memory, and wireless networking components, which support local data processing, data logging, and bi-directional wireless communication. Communication may be carried out with a server, with other spouts of like kind, and/or with other devices.
1. A spout configured to attach to a mouth of a bottle, the spout comprising:
a passageway extending through the spout and configured to pass liquid out of the bottle;
an IMU (inertial measurement unit) configured to track orientation and movement of the spout in three-dimensional space;
wireless communication circuitry configured to communicate bidirectionally with other electronic equipment that is not part of the spout; and
a pour detector constructed and arranged to detect a pour event and to compute, based on measurements from the IMU, horizontal translation of the spout during the pour event.
2. The spout of claim 1 , further comprising a visual indicator, visible from outside the spout and configured to convey visual information to a user.
3. The spout of claim 2 , wherein the visual indicator is configured to convey the visual information based on at least one of (i) measurements made by the IMU and (ii) wireless communication between the spout and an element of the other electronic equipment.
4. The spout of claim 1 , further comprising a transducer configured to convey sonic or other vibrational information to a user.
5. The spout of claim 4 , wherein the transducer includes at least one of a speaker or piezoelectric device configured to convey the sonic or other vibrational information based on at least one of (i) measurements made by the IMU and (ii) wireless communication between the spout and an element of the other electronic equipment.
6. The spout of claim 1 , further comprising a label, visible from outside the spout, which identifies a type of beverage to which the spout is assigned for use.
7. The spout of claim 6 , wherein the label is an electronic label configured by the spout in response to wireless communication between the spout and an element of the other electronic equipment.
8. The spout of claim 1 , wherein the spout is constructed and arranged to transmit information based on IMU measurements acquired during beverage pours to a server computer of the other electronic equipment.
9. The spout of claim 1 , wherein the spout is one of multiple spouts configured to communicate with one another in a cluster formed based on physical proximity.
10. The spout of claim 1 , further comprising a data log constructed and arranged to store IMU measurements associated with multiple pour events.
11. The spout of claim 1 , further comprising a kinematic engine configured to associate measurements from the IMU during pour events with respective users.
12. A method of monitoring beverage pours, comprising:
providing a spout attached to a mouth of a bottle, the spout housing electronic circuitry that includes (i) an IMU (inertial measurement unit) and (ii) wireless communication circuitry configured to communicate bidirectionally with a server computer;
detecting, by the spout, a pour event based at least in part on the IMU measuring orientation and movement of the spout in three-dimensional space; and
wirelessly transmitting information about the pour event to the server computer,
wherein the snout includes a set of indicators conveying visual and/or sonic information based on at least one of (i) measurements made by the IMU and (ii) wireless communication between the spout and the server computer.
13. The method of claim 12 , wherein conveying the visual and/or sonic information includes generating an indication of pouring progress during the pour event.
14. The method of claim 12 , wherein conveying the visual and/or sonic information includes outputting an indication in response to the server computer identifying the spout as being associated with a beverage order.
15. The method of claim 12 , further comprising translating the pour event into multiple pour events in response to the information about the pour event indicating a horizontal translation of the spout while the spout is in a tilted orientation.
16. The method of claim 12 , further comprising the spout identifying a user of the spout based on receiving a wireless signal from a device worn by the user of the spout.
17. The method of claim 12 , further comprising storing at least one database entry that associates the pour event with any of (i) a human person using the spout during the pour event, (ii) a POS (point of sale) entry for a particular drink order, and/or (iii) a video clip of the pour event acquired by a camera.
18. A method of monitoring beverage pours, comprising:
providing a spout attached to a mouth of a bottle, the spout housing electronic circuitry that includes (i) an IMU (inertial measurement unit) and iii) wireless communication circuitry configured to communicate bidirectionally with a server computer;
detecting, by the spout, a pour event based at least in part on the IMU measuring orientation and movement of the spout in three-dimensional space;
wirelessly transmitting information about the pour event to the server computer;
acquiring measurements by the IMU of position and orientation of the spout during the pour event;
generating a kinematic signature of the pour event based on the acquired measurements; and
identifying a current user of the spout based at least in part on matching the kinematic signature to one of multiple previously-stored kinematic signatures for respective users of the spout.
