Abstract

A magnetic field focusing assembly includes a magnetic field generating device configured to generate a magnetic field, and a split ring resonator assembly configured to be magnetically coupled to the magnetic field generating device and configured to focus the magnetic field produced by the magnetic field generating device.

Claims

1. An RFID system comprising:

an RFID antenna configured to be positioned on a product module of a processing system, wherein the product module is configured to engage at least one product container;

a first RFID tag configured to be positioned on the at least one product container, wherein the at least one product container is configured to position the first RFID tag within a detection zone of the RFID antenna whenever the product module engages the at least one product container; and

a split ring resonator configured to be magnetically coupled to the RFID antenna and configured to focus at least a portion of the magnetic field produced by the RFID antenna.

2. The system of claim 1 wherein the product module includes a pump assembly configured to engage at least one product container.

3. The system of claim 2 wherein the pump assembly is a solenoid piston pump.

4. The system of claim 2 wherein the processing system includes a manifold assembly for releasably engaging the pump assembly included within the product module.

5. The system of claim 4 wherein the manifold assembly is rigidly affixed to a bracket assembly of the processing system.

6. The RFID system of claim 1 further comprising:

a second RFID tag configured to be positioned on a bracket assembly, the bracket assembly configured to engage the product module and position the second RFID tag within a detection zone of the RFID antenna whenever the bracket assembly engages the product module assembly.

7. The system of claim 6 wherein at least one of the RFID tags is a passive RFID tag.

8. The system of claim 6 wherein at least one of the RFID tags is a writeable RFID tag.

9. The system of claim 6 wherein at least one of the RFID tags defines one or more of the following:

a quantity identifier for the product container, a production date identifier for the product container, a discard date identifier for the product container, an ingredient identifier for the product container, a product module identifier, and a bracket identifier.

10. The system of claim 1 further comprising an RFID subsystem coupled to the RFID antenna for processing data provided by the RFID antenna.

11. The system of claim 10 further comprising a user interface subsystem coupled to the RFID subsystem for providing information to the user of the processing system.

12. An RFID system comprising:

an RFID antenna configured to be positioned on a product module of a processing system, wherein the product module is configured to releasably engage at least one product container;

a first RFID tag configured to be positioned on a first product container, wherein the first product container is configured to position the first RFID tag within a detection zone of the RFID antenna whenever the product module assembly engages the first product container; and

a second RFID tag configured to be positioned on a second product container, wherein the second product container is configured to position the second RFID tag within a detection zone of the RFID antenna whenever the product module releasably engages the second product container; and

a split ring resonator configured to be magnetically coupled to the RFID antenna and configured to focus at least a portion of the magnetic field produced by the RFID antenna,

wherein the RFID antenna is configured to be positioned proximate the first RFID tag and the second RFID tag and to detect the presence of the first RFID tag and not detect the presence of the second RFID tag.

13. The system of claim 12 wherein the product module includes a pump assembly configured to engage at least one product container.

14. The system of claim 13 wherein the pump assembly is a solenoid piston pump.

15. The system of claim 13 wherein the processing system includes a manifold assembly for engaging the pump assembly included within the product module.

16. The system of claim 15 wherein the manifold assembly is rigidly affixed to a bracket assembly of the processing system.

17. The system of claim 12 wherein at least one of the RFID tags are a passive RFID tag.

18. The system of claim 12 wherein at least one of the RFID tags is a writeable RFID tag.

19. The system of claim 12 wherein at least one of the RFID tags defines one or more of the following:

a quantity identifier for the product container, a production date identifier for the product container, a discard date identifier for the product container, an ingredient identifier for the product container, a product module identifier, and a bracket identifier.

20. The system of claim 12 further comprising an RFID subsystem coupled to the RFID antenna for processing data provided by the RFID antenna.

21. The system of claim 20 further comprising a user interface subsystem coupled to the RFID subsystem for providing information to the user of the processing system.
