Abstract

Methods and systems for providing data communication in medical systems are disclosed.

Claims

1. An analyte monitoring device, comprising:

a data transmission section;

a data receiving section; and

a data processing section coupled to the data receiving section;

wherein the data receiving section is configured to receive a predefined command, and further, wherein the data processing section is configured to control the data transmission section to transmit one or more data in response to the received predefined command.

2. The device of claim 1 wherein the data receiving section includes a close proximity receiver.

3. The device of claim 1 wherein the data transmission section includes an RF transmitter.

4. The device of claim 1 including an antenna coupled to the data transmission section and the data receiving section for wireless data communication.

5. The device of claim 1 wherein the data processing section includes a state machine.

6. The device of claim 1 wherein the transmitted one or more data includes a device identification information.

7. The device of claim 1 wherein the transmitted one or more data includes a response data packet.

8. The device of claim 7 wherein the response data packet includes one or more of a communication mode information, a device status information, a device type information, a close proximity command information, or a sensor count information.

9. The device of claim 1 including a memory unit for storing data.

10. A method, comprising:

receiving a command to initiate communication with an analyte sensor;

retrieving an identification information;

transmitting the retrieved identification information; and

receiving a communication key associated with the transmitted identification information.

11. The method of claim 10 wherein the received command includes a close proximity command.

12. The method of claim 10 wherein the retrieved identification information is wirelessly transmitted over an RF communication link.

13. The method of claim 10 wherein the identification information includes a data processing device identification information.

14. The method of claim 13 wherein the data processing device identification information includes a transmitter identification information.

15. The method of claim 10 wherein the communication key includes an 8 bit data associated with the identification information.

16. The method of claim 10 including transmitting a data packet including the communication key.

17. The method of claim 10 including storing the communication key.

18. The method of claim 10 wherein the analyte sensor includes a glucose sensor.

19. The method of claim 10 including receiving one or more signals related to a monitored analyte level.

20. The method of claim 19 wherein the analyte level includes glucose level.
