Abstract

An RFID system provides a transponder having a power store that can be recharged when located within an electro-magnetic field generated by a transceiver unit. The power store can be a battery and/or a capacitor. In certain embodiments, the transponder can communicate over at least two different frequencies so that the real time performance of the transponder can be improved without losing backwards compatibility. The system provides an ear tag for use on livestock with superior durability and overall performance in the field.

Claims

1-12. -12. (canceled)

13. A dairy animal management system comprising:

a data manager installed at a milking parlor configured to allow one or more dairy animals to be milked, the data manager including an antenna configured to receive and send RF signals;

a plurality of identification tags configured to be attached to dairy animals that visit the milking station, each identification tag including an antenna configured to receive and send RF signals, a rechargeable power source that is configured to harvest power from the data manager while the dairy animal is located at the milking parlor, memory configured to store data pertaining to the dairy animal, and a processor configured to access the data and send at least a portion of the data to the data manager; and

a data manager interface communicatively coupled to the data manager to obtain the data supplied from the identification tags.

14. The dairy animal management system of claim 13, wherein each identification tag is configured to harvest power from data signals sent by the data manager.

15. The dairy animal management system of claim 13, wherein each identification tag is configured to harvest power from power signals sent by the data manager.

16. The dairy animal management system of claim 13, wherein each identification tag harvests sufficient power during each milking session to enable operation of the identification tag until at least a next scheduled milking session.

17. The dairy animal management system of claim 16, wherein each identification tag harvests sufficient power during each milking session to enable operation of the identification tag even if the next scheduled milking session is missed.

18. The dairy animal management system of claim 13, wherein the data manager supplies power to each identification tag for no more than about three hours.

19. The dairy animal management system of claim 13, wherein the data manager supplies power to each identification tag for about thirty minutes per milking session.

20. The dairy animal management system of claim 13, wherein the data manager supplies power to each identification tag for about ten minutes per milking session.

21. The dairy animal management system of claim 13, wherein the data manager supplies power to each identification tag for about one hour per milking session.

22. The dairy animal management system of claim 13, wherein each identification tag is configured to harvest about ten milliamps of current at about three volts in a single milking session.

23. The dairy animal management system of claim 13, wherein the memory of each identification tag stores an identification number associated with the respective dairy animal.

24. The dairy animal management system of claim 23, wherein the memory of each identification tag also stores activities of the dairy animal.

25. The dairy animal management system of claim 13, wherein the data manager is located at a milking station within the milking parlor.

26. The dairy animal management system of claim 13, further comprising:

a plurality of additional data managers, each additional data manager being installed at an additional milking station; and

a plurality of additional identification tags configured to be attached to dairy animals that visit the additional milking stations, each identification tag including an antenna configured to receive and send RF signals, a rechargeable power source that is configured to harvest power from the respective additional data manager while the dairy animal is located at the respective additional milking station, memory configured to store data pertaining to the dairy animal, and a processor configured to access the data and send at least a portion of the data to the respective additional data manager;

wherein the data manager interface services each of the additional data managers.

27. The dairy animal management system of claim 26, wherein the data manager interface is coupled to at least some of the additional managers using a wireless connection.

28. A method of managing dairy animals comprising:

sending query signals from a data manager located at a milking stall;

receiving at the data manager an identification signal from an identification tag when a dairy animal is located at the milking stall, the identification signal identifying the dairy animal;

providing a power signal configured to be harvested by the identification tag while the identification tag is located at the milking stall; and

sending data obtained from the received identification signal to a data manager interface.

29. The method of claim 28, further comprising sending updated data obtained from the data manager interface to the identification tag.

30. The method of claim 29, wherein the updated data includes updated medical records for the dairy cow.

31. The method of claim 28, further comprising receiving data pertaining to a production history of the dairy animal.

32. The method of claim 28, further comprising receiving data indicating the amount of milk obtained from the animal during each visit.
