Animal health monitoring system

1. An animal health monitoring system, comprising:

a ruminant bolus transponder comprising at least one physiological sensor, a microcontroller with memory, a low frequency radio frequency identification (RFID) transceiver, and a high frequency radio frequency transmitter;

at least one high frequency radio frequency (RF) transceiver device comprising at least one physiological sensor, a microcontroller, and a high frequency radio frequency transceiver; and

at least one base station comprising a high frequency radio frequency transceiver;

wherein the high frequency radio frequency transceiver device is proximally located to the ruminant bolus transponder;

wherein the ruminant bolus transponder periodically emerges from a low power dormant state and measures data comprising at least one sensor measurement comprising time and date data;

wherein the ruminant bolus transponder is configured to store the measured data using the memory connected to the microcontroller in the ruminant bolus;

wherein the ruminant bolus transponder periodically emerges from a low power dormant state and transmits the stored data in the memory to the proximally located device via high frequency RF transmission; and

wherein the ruminant bolus transponder can be spontaneously activated by a low frequency scanner.

2. The animal health monitoring system of claim 1 , wherein the low frequency scanner configures the ruminant bolus transponder to transmit the stored data.

3. The animal health monitoring system of claim 1 , wherein the low frequency scanner is configured to reconfigure the ruminant bolus transponder.

4. The animal health monitoring system of claim 3 , wherein the low frequency scanner transmits configuration data and time/date synchronization to the ruminant bolus transponder.

5. The animal health monitoring system of claim 1 , wherein:

the high frequency radio frequency transceiver device emerges from a low power dormant state at intervals synchronous with the ruminant bolus transponder; and

the high frequency radio frequency transceiver device receives at least one piece of data via high frequency RF transmission.

6. The animal health monitoring system of claim 1 , wherein the high frequency radio frequency transceiver device emerges from a low power dormant state and records data comprising at least one sensor measurement associated with current time and date in memory.

7. The animal health monitoring system of claim 1 , wherein:

the high frequency radio frequency transceiver device emerges from a low power dormant state at intervals synchronous with the at least one base station; and

the high frequency radio frequency transceiver device transmits stored data records comprising ruminant bolus transponder data and proximal device data via high frequency transmission.

8. The animal health monitoring system of claim 1 , wherein the low frequency scanner obtains data stored on the ruminant bolus transponder.

9. The animal health monitoring system of claim 1 , wherein the low frequency scanner reads a bolus identification number and sensor data stored in the ruminant bolus transponder.

10. The animal health monitoring system of claim 1 , wherein the base station broadcasts polling requests to at least one high frequency radio frequency transceiver device.

11. The animal health monitoring system of claim 10 , wherein the base station is configured to broadcast via high frequency RF.

12. The animal health monitoring system of claim 11 , wherein a polling request is addressed to at least one high frequency radio frequency transceiver device.

13. The animal health monitoring system of claim 11 , wherein the high frequency radio frequency transceiver device responds to the polling request by transmitting requested stored sensor data.
