Claims17
A product monitoring system comprising:
- a product module assembly for receiving a plurality of product modules, each product module having a RFID tag assembly;
- a first magnetic field generating device;
- a first split ring resonator assembly configured to focus at least a portion of a magnetic field produced by the first magnetic field generating device, wherein the first magnetic field generating device is configured to be positioned proximate a first module with a first RFID tag assembly to detect the presence of the first RFID tag assembly;
- a second magnetic field generating device;
- and
- a second split ring resonator assembly configured to focus at least a portion of a magnetic field produced by the second magnetic field generating device, wherein the second magnetic field generating device is configured to be positioned proximate a second module with a second RFID tag assembly to detect the presence of the second RFID tag assembly.
