Abstract

Methods and apparatus for providing close proximity detection in medical systems are disclosed.

Claims

1. A method, comprising:

receiving an encoded data packet including one or more error detection bits, one or more close proximity commands, and a communication identifier;

decoding the received data packet;

performing error detection based on the one or more error detection bits;

validating the decoded received data packet; and

executing one or more routines associated with the respective one or more close proximity commands when the decoded received data packet is validated;

wherein the executed one or more routines includes transmitting analyte related data.

2. The method of claim 1 wherein the received data packet is Manchester encoded.

3. The method of claim 1 wherein the one or more error detection bits include a predetermined bit pattern.

4. The method of claim 3 wherein the predetermined bit pattern includes a dotting pattern.

5. The method of claim 1 wherein decoding the received data packet includes performing Manchester decoding.

6. The method of claim 1 wherein validating the decoded received data packet includes comparing the received communication identifier in the data packet with a stored value.

7. The method of claim 1 wherein the communication identifier includes a device identification information.

8. The method of claim 1 wherein the one or more routines are associated with the operation of an analyte monitoring device.

9. The method of claim 1 wherein the executed one or more routines includes a power on routine, a power off routine, a data transfer initiation routine, or a data transfer disable routine.

10. The method of claim 1 wherein the analyte related data includes a monitored analyte level.

11. The method of claim 10 wherein the analyte is glucose.

12. The method of claim 1 including storing the received data packet.

13. A method, comprising:

receiving an encoded data packet including a close proximity command and a communication identifier;

decoding the received data packet;

validating the decoded received data packet; and

executing one or more routines associated with the respective one or more close proximity commands when the decoded received data packet is validated.

14. The method of claim 13 wherein the encoded data packet is Manchester encoded.

15. The method of claim 13 wherein decoding the received data packet includes performing Manchester decoding.

16. The method of claim 13 wherein validating the decoded received data packet includes comparing the received communication identifier in the data packet with a stored value.

17. The method of claim 13 wherein validating the decoded received data packet includes performing error detection on the data packet.

18. The method of claim 17 wherein performing error detection includes comparing one or more data pattern in the received data packet.

19. The method of claim 13 wherein the communication identifier includes a device identification information.

20. The method of claim 13 wherein the one or more routines are associated with the operation of an analyte monitoring device.
