Abstract

A system for monitoring a plurality of screen panels configured for use in a materials screening process is provided. The system includes a plurality of screen panels. Each screen panel is coupled to a radio frequency identification (RFID) circuit which is configured to alter its behavior if its associated screen panel breaks.

Claims

1. A system for monitoring a status of a screen panel configured for use in a material screening process, the system comprising:

a screen panel configured for use in the material screening process;

an antenna coupled to the screen panel and configured to receive first electromagnetic energy; and

a processing circuit coupled to the screen panel and the antenna, the processing circuit configured to receive a signal from the antenna regarding the first electromagnetic energy and to cause the transmission of second electromagnetic energy in response to the receipt of the signal.

2. The system of claim 1, wherein the antenna is embedded within the screen panel.

3. The system of claim 1, wherein the screen panel is arranged to include a plurality of rows and columns of apertures and wherein a conductor system for the antenna is embedded around at least one of the apertures of the screen panel.

4. The system of claim 1, wherein the screen panel is arranged to include a plurality of rows and columns of apertures and wherein a conductor system for the antenna is embedded around a majority of the rows and columns of the apertures of the screen panel.

5. The system of claim 4, wherein the conductor system of the antenna forms a circuit which will not successfully receive the first electromagnetic energy and/or transmit the second electromagnetic energy when a portion of the screen panel is broken.

6. The system of claim 4, wherein the conductor system of the antenna forms a circuit which the processing circuit is configured to monitor for a status condition, wherein the processing circuit is configured to alter information represented by the second electromagnetic energy based on the status condition.

7. The system of claim 4, wherein the conductor system of the antenna forms a circuit, and wherein the processing circuit is configured to alter its operation if the circuit is broken.

8. The system of claim 1, wherein the screen panel is a screen configured to allow the material to flow and/or fall through openings formed by the screen, wherein the screen is formed from at least one of plastic, rubber, ceramic, and glass.

9. The system of claim 1, wherein the processing circuit is assigned a unique identifier that is communicated with the second electromagnetic energy in response to the receipt of the signal.

10. The system of claim 1, wherein the antenna and the processing circuit form a passive radio frequency identification (RFID) circuit.

11. The system of claim 1, wherein the processing circuit is coupled to a power supply and the antenna and the processing circuit form an active radio frequency identification (RFID) circuit.

12. The system of claim 1, further comprising:

a reader located remotely from the screen panel and configured to transmit the first electromagnetic energy to the antenna, wherein the reader is configured to determine the status of the screen panel based on one of;

(a) whether the second electromagnetic energy is received by the reader; and

(b) information represented by second electromagnetic energy received by the reader.

13. The system of claim 12, wherein the reader is configured to monitor for radio frequency (RF) responses from a plurality of antennas and processing circuits coupled to a plurality of screen panels.

14. The system of claim 13, wherein the reader is configured to identify one or more broken screen panels based on received RF responses.

15. The system of claim 13, wherein the reader is configured to identify one or more broken screen panels based on which screen panels having antennas and processing circuits do not return RF responses to the reader.

16. The system of claim 13, wherein the reader is configured to provide data regarding the broken screen panels to a processing system configured to communicate at least one of the identification and the location of the broken screen panels to a user.

17. The system of claim 13, wherein the reader is configured to build a map of screen panels based on responses received from the screen panels.

18. A screen panel configured for use in a materials screening process, comprising:

a mesh structure;

an antenna embedded within the mesh structure; and

a processing circuit coupled to the mesh structure and the antenna,

wherein the antenna is configured so that a break in the mesh structure changes a signal provided from the antenna to the processing circuit when electromagnetic energy is received by the antenna.

19. A system for monitoring a plurality of screen panels configured for use in a materials screening process, the system comprising:

a plurality of screen panels, wherein each screen panel is coupled to a radio frequency identification (RFID) circuit which is configured to alter its behavior if its associated screen panel breaks.

20. The system of claim 19, wherein each screen panel is arranged to include a plurality of rows and columns of apertures and a conductor system for an antenna is embedded around a plurality of the apertures of the screen panel, wherein the RFID circuit altering its behavior if its associated screen panel breaks comprises experiencing a break in the conductor system that affects the RFID circuit'"'"'s operation.

21. The system of claim 20, further comprising:

a reader system having a transceiver configured to communicate with the RFID circuits of the plurality of screen panels, the reader system configured to determine if any of the screen panels are broken based on communication between the transceiver and the RFID circuits.

22. The system of claim 21, wherein the reader system is further configured to identify which of the screen panels are broken based on the communication.

23. A system for monitoring an apparatus, the system comprising:

a radio frequency identification (RFID) circuit; and

a conductor system coupled to the apparatus and the RFID circuit, the conductor system configured to break when the apparatus breaks, wherein the RFID circuit is configured to alter its behavior when the conductor system breaks.
