Abstract

A method and system of managing inventory of consumables stored in containers including associating with a container a sensor configured to determine an indication of the amount of an attribute, such as an indication of an amount of substance stored in the container, and storing the indication of amount at various times as a usage history.

Claims

1. A method of managing inventory, comprising:

associating a sensor with the container, the sensor configured to determine an indication of the amount of a substance stored in the container;

receiving a first indication of the amount of the substance from the sensor at each of a plurality of points in time; and

storing a second indication of the amount derived from the first indication of the amount with each point in time as a usage history.

2. The method of claim 1 wherein the second indication of the amount is the same as the first indication of the amount.

3. The method of claim 1 wherein the second indication of amount is calculated from the first indication of amount and geometric information about the container.

4. The method according to claim 1, further comprising:

processing the first indications of amounts of the usage history over a usage period; and

calculating a usage rate for the period from the first indications of the amounts.

5. The method according to claim 4, further comprising calculating an expected depletion date based on a current indication of the amount and the usage rate.

6. The method according to claim 5, further comprising establishing a replenishment date for the substance based on the expected depletion date.

7. The method according to claim 6, wherein the replenishment date is the expected depletion date.

8. The method according to claim 6, wherein the replenishment date is prior to the expected depletion date.

9. The method of claim 1 wherein the second indication of the amount is calculated from the first indication of the amount and the prior indication of the amount and reflects the change in the amount of substance since a previous first indication of amount.

10. The method according to claim 9, further comprising:

summing the second indications of the amounts of the usage history over a usage period; and

calculating a usage rate for the period based on the summing and a length of the usage period.

11. The method according to claim 1, further comprising associating an expected unit cost with the substance.

12. The method according to claim 11, further comprising:

receiving current price and quantity data from at least one provider of the substance;

calculating a current unit price based on the current price and quantity data;

determining whether an available capacity can accommodate an additional quantity if the current unit price is less than the expected unit price.

13. The method according to claim 12, wherein the current price and quantity data includes a date range during which the current price and quantity data is valid.

14. The method according to claim 1, further comprising storing usage histories of a plurality of substances stored in a plurality of containers.

15. The method according to claim 14, further comprising compiling a shopping list from the usage histories.

16. The method according to claim 14, further comprising compiling a menu from the usage histories.

17. The method according to claim 1, further comprising associating a plurality of indications of attributes of the substance.

18. The method according to claim 17, further comprising processing the plurality of indications of attributes and determining a disposal date for the substance.

19. The method according to claim 18, further comprising processing the plurality of indications of attributes and determining a depletion date for the substance.

20. The method according to claim 19, further comprising comparing the disposal date with the expected depletion date and generating a notification in response to the comparing.

21. The method according to claim 20, wherein if the disposal date is earlier than the depletion date, the notification advises a user that the substance will need to be disposed before the expected depletion date.

22. The method according to claim 20, further comprising establishing a replacement date in consideration of the earlier of the expected depletion date and the disposal date.

23. A method of managing inventory, comprising:

sensing at least one attribute of a domestic consumable substance stored in a portable container at each of a plurality of points in time during a usage period;

transmitting information about the at least one attribute and an identifier;

receiving the information at each of a plurality of points in time during the usage period; and

storing the information with each point in time as a usage history.

24. The method according to claim 23, further comprising:

summing the amounts of the usage history over the usage period; and

calculating a usage rate for the period based on the summing and a length of the usage period.

25. The method according to claim 23, further comprising calculating an expected depletion date based on a current indication of amount and the expected depletion date.

26. The method according to claim 25, further comprising establishing a replenishment date for the substance based on the expected depletion date.

27. The method according to claim 26, wherein the replenishment date is the expected depletion date.

28. The method according to claim 26, wherein the replenishment date is prior to the expected depletion date.

29. The method according to claim 23, further comprising associating an expected unit cost with the substance.

30. The method according to claim 29, further comprising:

receiving current price and quantity data from at least one provider of the substance;

calculating a current unit price based on the current price and quantity data;

determining whether an available capacity can accommodate an additional quantity if the current unit price is less than the expected unit price.

31. The method according to claim 29, wherein the current price and quantity data includes a date range during which the current price and quantity data is valid.

32. A method of managing inventory, comprising:

sensing at least one attribute of quantity of a domestic consumable substance stored in a portable container at each of a plurality of points in time during a usage period;

storing the information with each point in time as a usage history;

associating an expected unit cost with the substance;

receiving current price and quantity data from at least one provider of the substance;

calculating a current unit price based on the current price and quantity data;

calculating the usage rate of the substance from the usage history; and

determining from the current amount and the usage rate and the current unit price if an additional amount should be purchased.

33. The method according to claim 32, further comprising comparing the current unit price with the expected unit price and using the comparison in the determining.

34. The method according to claim 32, further comprising calculating an expected depletion date from the usage rate and using the expected depletion rate in the determining.

35. The method according to claim 34, further comprising adjusting the expected depletion rate for the expiration date of the substance, if the expiration date is earlier.

36. The method according to claim 35, further comprising calculating the expiration date from usage data.

37. The method according to claim 32, wherein the current price and quantity data includes a date range during which the current price and quantity data is valid.

38. The method according to claim 32 further comprising generating a notification recommending increased consumption of the substance.

39. A system for managing inventory of a plurality of portable containers of substance, each having a sensor configured to determine a first indication of the amount of a substance stored in the container and a transmitter configured to transmit the first indication of the amount, the system comprising:

a receiver capable of receiving the first indications of the amount from each container of substance at each of a plurality of points in time;

a data processing system capable of processing the first indication of the amount to determine a second indication of the amount; and

capable of processing a plurality of second indications of the amount generated at a plurality of points in time to generate a usage history; and

a data storage system capable of storing the second indications of the amount and the usage history of each substance.
