Abstract

Information from an object having an RFID tag is received and state information about the object is received from a sensing device. A state is determined for the object using the information from the tag and the sensing device, and the state is assigned to the object.

Claims

1. A method comprising:

receiving information from at least one RFID tag reading device, wherein the information is read from an RFID tag by the at least one RFID tag reading device and the RFID tag is associated with an object;

receiving state information from at least one sensing device;

determining a state for the object, wherein the state is determined from the state information received from the at least one sensing device; and

assigning the determined state to the object using the information received from the at least one RFID tag reading device.

2. The method of claim 1, wherein assigning the determined state to the object further comprises:

using a virtualization module to determine the state for the object from the received state information, to assign the state to the object, and to convert the assigned state for the object into a predetermined value representing the assigned state of the object.

3. The method of claim 2, wherein the virtualization module is operable to simulate the use of multiple RFID tag reading devices to determine different states for the object.

4. The method of claim 1, wherein the at least one sensing device and the at least one RFID tag reading device are configured to monitor a single point, and wherein the determined state represents a direction of movement through the single point, the method further comprising:

converting the determined state into a predetermined value, wherein the predetermined value is selected from one of entry into a dedicated virtual entry point or exit from a dedicated virtual exit point.

5. The method of claim 4, wherein the object is included in inventory;

the method further comprising;

tracking the inventory using the at least one sensing device and the at least one RFID tag reading device.

6. The method of claim 5, wherein tracking the inventory further comprises:

using inventory tracking software to track the inventory, wherein the inventory tracking software receives information obtained from the at least one RFID tag reading device and the at least one sensing device in the form of the predetermined values derived by a virtualization module and understood by the inventory tracking software.

7. The method of claim 1, wherein the state for the object comprises at least one of a determination that the object is a predetermined size, a determination that the object is a good, and a determination that the object is a human.

8. A system comprising:

at least one sensing device operable to sense state information for an object;

at least one reading device operable to read the information contained in an RFID tag associated with the object; and

a virtualization module operable to determine a state for the object from the state information and convert the state to a predetermined value used as data input for an RFID software application.

9. The system of claim 8, wherein the RFID software application comprises:

tracking software operable to track RFID tagged objects read by the at least one reading device and sensed by the at least one sensing device.

10. The system of claim 9, wherein the virtualization module is further operable to assign the determined state to the object using the information read from the RFID tag, wherein the state is represented as a virtual model.

11. The system of claim 8, wherein the at least one sensing device is operable to sense both motion and direction of motion.

12. The system of claim 8, wherein the at least one sensing device comprises at least one of a camera system, an infra red system, and a pressure sensing system.

13. The system of claim 8, further comprising:

a plurality of objects each having an RFID tag, wherein the at least one sensing device is operable to sense directional information for the plurality of objects and the virtualization module is operable to determine a state for each of the plurality objects from the directional information for the object; and

a host operable to receive the states of the plurality of objects and further operable to monitor the plurality of objects based on the states.

14. The system of claim 13, wherein the host is operable to monitor the plurality of objects entering and exiting a location.

15. The system of claim 13, wherein the host is operable to store whether the plurality objects have entered or exited the location.

16. The system of claim 15, wherein the location comprises a single point where the plurality of objects are operable to enter or exit and the virtualization module is operable to represent the single point as a dedicated virtual entry point and a dedicated virtual exit point for the location.

17. The system of claim 8, wherein the state of the object comprises at least one of a determination that the object is a predetermined size, a determination that the object is a good, and a determination that the object is a human.

18. An entry/exit point comprising:

at least one sensing device;

at least one reading device operable to read the information contained in an RFID tag, wherein the RFID tag is associated with an object; and

a computing device operable to determine a state for the object from the information received from the sensing device;

further operable to assign the determined state to the object; and

further operable to convert the assigned state of the object into a predetermined value, wherein the predetermined value represents the object passing through one of multiple virtual points.

19. The entry/exit point of claim 18, wherein the predetermined value is one of entry into a dedicated virtual entry point and exit from a dedicated virtual exit point.

20. The entry/exit point of claim 18, wherein the predetermined value comprises at least one of entry into a dedicated virtual entry point only for objects of a predetermined size, entry into a dedicated virtual entry point only for objects that are goods, and entry into a dedicated virtual entry point only for objects that are humans.

21. A computer readable medium upon which is stored a computer program including instructions which when executed by a processor cause the processor to perform the following steps, wherein the steps comprise:

receiving information from at least one reading device, wherein the information includes identification information from an RFID tag, wherein the RFID tag is associated with an object;

receiving state information from at least one sensing device;

determining a state from the state information;

assigning the determined state to the object; and

converting the determined state into a predetermined value.

22. The computer readable medium of claim 21, further comprising:

tracking the movement of the object, wherein the movement of the object is tracked with the predetermined value.

23. The computer readable medium of claim 22, wherein the virtualization module is operable to simulate virtual reading devices.
