Abstract

Embodiments are provided for determining and managing an inventory. The position of an object in an inventory may be determined by utilizing an interrogator to send multiple request signals to a tag attached to the object. Each of the request signals may be communicated by the interrogator at a different frequency. The interrogator may then receive multiple reply signals from the tag. The interrogator may then determine the position of the tag (and thus the object) along a transmission line from phase measurements of the reply signals. A dispenser inventory may be managed. The dispenser may identify an ingredient packaging to be inserted into an ingredient matrix of the dispenser. The dispenser may then receive a user input of a location within the ingredient matrix where the identified ingredient packaging has been inserted.

First claim

What is claimed is:

1 . A computer-implemented method of determining a position of a tag, comprising:
sending, by an interrogator, a plurality of request signals, each of the plurality of request signals being communicated at a different frequency; receiving, by the interrogator, a plurality of reply signals from the tag; and determining a position of the tag along a transmission line from phase measurements of the plurality of reply signals.

2 . The method of claim 1 , wherein each of the plurality of request signals is communicated along the transmission line.

3 . The method of claim 1 , wherein the position of the tag is at least one of a relative position and an absolute position along the transmission line.

4 . The method of claim 1 , wherein the transmission line extends alone one or more dimensions.

5 . The method of claim 1 , wherein the phase measurements are determined based on a relative magnitude of I and Q channels of the plurality of reply signals.

6 . The method of claim 1 , wherein each of the plurality of reply signals includes an identification of the tag.

7 . The method of claim 1 , wherein determining the position of the tag comprises:
determining a phase signature of the tag from the phase measurements; and correlating the phase signature of the tag to a predetermined phase signature of a location along the transmission line.

8 . The method of claim 1 , further comprising:
receiving a second plurality of reply signals from another tag; and determining a position of the other tag along the transmission line from phase measurements of the second plurality of reply signals.

9 . The method of claim 8 , wherein the position determined for the other tag is distinct from the position determined for the tag.

10 . An interrogator comprising:
a memory for storing executable program code; and a processor, functionally coupled to the memory, the processor being responsive to computer-executable instructions contained in the program code and operative to:
send a plurality of request signals, each of the plurality of request signals being communicated at a different frequency;
receive a plurality of reply signals from a first tag; and
determine a position of the first tag along a transmission line from phase measurements of the plurality of reply signals.

11 . The interrogator of claim 10 , wherein each of the plurality of request signals is communicated along the transmission line.

12 . The interrogator of claim 10 , wherein the position of the first tag is at least one of a relative position and an absolute position along the transmission line.

13 . The interrogator of claim 10 , wherein the transmission line extends alone one or more dimensions.

14 . The interrogator of claim 10 , wherein the phase measurements are determined based on a relative magnitude of I and Q channels of the plurality of reply signals.

15 . The interrogator of claim 10 , wherein each of the plurality of reply signals includes an identification of the first tag.

16 . The interrogator of claim 10 , wherein determining the position of the first tag comprises:
determining a phase signature of the first tag from the phase measurements; and correlating the phase signature of the first tag to a predetermined phase signature of a location along the transmission line.

17 . The interrogator of claim 10 , wherein the processor is further operative to:
receive a second plurality of reply signals from a second tag; and determine a position of the second tag along the transmission line from phase measurements of the second plurality of reply signals, wherein the position of the second tag is distinct from the position of the first tag.

18 . A computer-readable storage medium storing computer executable instructions which, when executed by a computing device, will cause the computing device to perform a method of determining a position of a tag, the method comprising:
sending a plurality of request signals, each of the plurality of request signals being communicated at a different frequency; receiving a plurality of reply signals from the tag; and determining a position of the tag along a transmission line from phase measurements of the plurality of reply signals.

19 . The computer-readable storage medium of claim 18 , wherein each of the plurality of request signals is communicated along the transmission line.

20 . The computer-readable storage medium of claim 18 , wherein the position of the tag is at least one of a relative position and an absolute position along the transmission line.

21 . The computer-readable storage medium of claim 18 , wherein the transmission line extends alone one or more dimensions.

22 . The computer-readable storage medium of claim 18 , wherein the phase measurements are determined based on a relative magnitude of I and Q channels of the plurality of reply signals.

23 . The computer-readable storage medium of claim 18 , wherein each of the plurality of reply signals includes an identification of the tag.

24 . The computer-readable storage medium of claim 18 , wherein determining the position of the tag comprises:
determining a phase signature of the tag from the phase measurements; and correlating the phase signature of the tag to a predetermined phase signature of a location along the transmission line.

25 . The computer-readable storage medium of claim 18 , further comprising:
receiving a second plurality of reply signals from another tag; and determining a position of the other tag along the transmission line from phase measurements of the second plurality of reply signals.

26 . The computer-readable storage medium of claim 25 , wherein the position determined for the other tag is distinct from the position determined for the tag.

27 . A computer-implemented method of managing a dispenser inventory, comprising:
identifying an ingredient packaging to be inserted into an ingredient matrix of a dispenser; and receiving a user input of a location within the ingredient matrix where the identified ingredient packaging has been inserted.

28 . The method of claim 27 , wherein identifying an ingredient packaging to be inserted into an ingredient matrix of a dispenser comprises reading a tag on the ingredient packaging to identify a beverage product contained in the ingredient packaging.

29 . The method of claim 27 , wherein identifying an ingredient packaging to be inserted into an ingredient matrix of a dispenser comprises reading a tag on the ingredient packaging to identify a cleaning fluid, the cleaning fluid being utilized to flush one or more supply lines in the dispenser.

30 . The method of claim 27 , wherein identifying an ingredient packaging to be inserted into an ingredient matrix of a dispenser comprises reading a tag on the ingredient packaging to identify a priming fluid, the priming fluid being utilized to prime one or more supply lines in the dispenser.

31 . The method of claim 27 , wherein receiving a user input of a location within the ingredient matrix where the identified ingredient packaging has been inserted comprises:
displaying a user interface comprising a representation of the ingredient matrix; receiving a selection of an icon corresponding to the identified ingredient packaging
