Patent Images
1. A system for tracking transported grain, the system comprising:
- a writer for recording data into an RFID tag, the data including at least a time when the RFID tag was handled with surrounding grain and information sufficient to determine a location of handling at the time when the RFID tag was handled with surrounding grain;
a reader for retrieving said recorded data from the RFID tag;
a radio-frequency identification (RFID) tag dimensioned to have a size approximating surrounding grain, said tag comprising a memory and an RF communication channel, wherein said writer records the data in the memory, and wherein said reader retrieves the recorded data from the memory;
a remover for removing said RFID tag from surrounding grain;
wherein said remover comprises;
a container for holding RFID tags;
a magnet for magnetically attracting the RFID tags; and
a moving surface for moving said magnetically attracted RFID tags towards said container, said moving surface being disposed between said magnet and the surrounding grain including the RFID tags;
said moving surface moving said magnetically attracted RFID tags to a location wherein the RFID tags are sufficiently displaced from a force of said magnet and is permitted to freely fall into said container.
