System, article and method for tracking an inventory
First Claim
1. A system for tracking inventory comprising:
- an inventory store;
one or more transceivers for interrogating one or more radio frequency identification devices associated with one or more articles;
a processor in communication with the transceivers;
code operable by the processor to increase the inventory when the one or more articles enter the inventory store;
code operable by the processor to initiate a timer when the one or more articles are removed from the inventory store;
code operable by the processor to decrease the inventory if one or more transceiver interrogations of a field indicate that the one or more articles removed from the inventory store does not respond to the interrogation or have been used; and
whereby if one or more transceiver interrogations of a field indicate that the one or more articles removed from the inventory store have not been used, then the inventory is unchanged for the responding one or more articles provided that the timer has not timed out.

Abstract
The present invention pertains to a storage facility containing consumable items that updates an inventory when items are stored, removed and consumed. A product scanner and a computer installed in the facility use RFID technology to determine if an item has been consumed or removed from a locale. Items in the facility have RFID tags attached. The system interrogates the tags and if a tag becomes disabled, displaced or non-existent due to consumption or removal from a locale the system provides instantaneous status. The computer transmits consumption information to a central location for billing, inventory management, market research information and can transmit the same to other processing units such as hand held computers possessed by staff that replenishes the facility. This system prevents used items from being placed back into the housing facility and being incorrectly accounted for as usable/billable and provides for greater room servicing efficiencies.

- an inventory store;
- 11. A container comprising a disabling means and a radio frequency identification device antenna integral to a seal whereby the disabling means acts upon the seal to open the container and disable the antenna.
-
12. A container comprising a cap, a body and a tab, wherein an associated antenna is connected to the tab and the body of the container whereby when the tab is removed it disables the antenna.
- 16. A seal comprising a disabling means and a radio frequency identification device antenna integral to the seal whereby the disabling means acts upon the seal to disable the antenna.
- 18. A label comprising a disabling means and a radio frequency identification device antenna integral to the label whereby the disabling means acts upon the label to disable the antenna.

20. A method for tracking inventory comprising:
- stocking an inventory store;
interrogating a radio frequency identification device associated with one or more articles in the inventory store;
processing a communication to record the one or more articles entering the inventory store to increase inventory;
initializing a timer when the one or more articles are removed from the inventory store;
interrogating the one or more articles removed from the inventory store; and(a) decreasing the inventory for the one or more articles if the radio frequency identification device of one or more articles removed from the inventory store indicate that the one or more articles have been used; and (b) not changing the inventory for the responding one or more articles if the radio frequency identification device of one or more articles removed from the inventory store response indicate the one or more articles have not been used provided that the reentering the one or more articles into the interrogation field or the inventory store occurs before the timer times out. - View Dependent Claims (21, 22, 23, 24, 25)
