RFID INVENTORY DEVICE
First Claim
1. A radio frequency identification (RFID) inventory device for use with one or more containers, the device comprising:
- an antenna supporting wireless interrogation by an external RFID reader;
a RFID chip coupled to said antenna having an embedded unique identifier and a memory element, wherein said RFID chip is adapted to store in said memory element at least one quantity value associated with said objects stored in said one or more containers, wherein said RFID chip is adapted to allow said external reader to wirelessly collect said identifier and said at least one quantity value in response to said wireless interrogation; and
one or more sensors coupled to said RFID chip, wherein said one or more sensors are configured to send at least one signal to said RFID chip in response to a change in said quantities of said objects in said one or more containers;
wherein said RFID chip is configured to update said at least one quantity value stored in said memory element in response to said at least one signal from said one or more sensors.

Abstract
A radio frequency identification (RFID) inventory device attached to a container for tracking quantities of objects stored in the container having an antenna supporting wireless interrogation by an external RFID reader, a RFID chip coupled to the antenna having an embedded unique identifier and a memory element, where the RFID chip is adapted to store in the memory element at least one quantity value and to allow an external reader to wirelessly collect the identifier and at least one quantity value in response to said wireless interrogation, and one or more sensors coupled to the RFID chip, where the sensors are configured to send at least one signal to the RFID chip in response to a change in quantities of objects in the container and where the RFID chip is configured to update at least one quantity value stored in response to a signal from the sensors.

8. A method for updating at least one quantity value stored in an RFID inventory device associated with a container, the method comprising the steps of:
-
sending at least one signal from one or more sensors in said container to an RFID chip of said RFID inventory device in response to a change in quantities of objects stored in said container; and updating at least one quantity value associated with said quantities of objects stored in said container in a memory element of said RFID chip in response to said RFID chip receiving said at least one signal. - View Dependent Claims (9, 10, 11, 12, 13, 14)
