Abstract

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

Claims

1. An analyte monitoring system, comprising:

a data processing unit; and

a control unit in wireless communication with the data processing unit, the control unit configured to transmit one or more predefined close proximity commands to the data processing unit;

wherein the data processing unit is configured to perform one or more predefined functions in response to the received one or more predefined close proximity commands.

2. The system of claim 1 wherein the data processing unit includes a close proximity receiver coupled to an antenna for receiving the one or more predefined close proximity commands from the control unit.

3. The system of claim 1 wherein the data processing unit is configured to transmit one or more signals related to a monitored analyte level in response to the received one or more predefined close proximity commands.

4. The system of claim 3 wherein the communication of the one or more predefined close proximity commands is performed when the data processing unit and the control unit are within a predetermined distance from each other.

5. The system of claim 4 wherein the predetermined distance includes a distance of less than one foot.

6. The system of claim 1 including a memory unit.

7. The system of claim 6 wherein the memory unit includes an EEPROM.

8. The system of claim 1 wherein the control unit includes an application specific integrated circuit (ASIC) configuration.

9. The system of claim 1 including an analyte sensor coupled to the data processing unit, wherein the data processing unit receives one or more signals from the analyte sensor.

10. The system of claim 9 wherein the control unit and the data processing unit are in wireless communication using RF communication protocol.

11. A method, comprising:

positioning a controller unit within a transmission range for close proximity communication;

transmitting one or more predefined close proximity commands; and

receiving a response packet in response to the transmitted one or more predefined close proximity commands.

12. The method of claim 11 including generating a communication key associated with the response packet.

13. The method of claim 12, wherein the communication key is generated based on at least in part, a transmitter unit identification information.

14. The method of claim 13 wherein the transmitter unit identification information is included in the response packet.

15. The method of claim 11 wherein the transmission range includes a distance of less than one foot.

16. The method of claim 11 including storing one or more of the predefined close proximity commands or the response packet.

17. The method of claim 16 wherein storing includes storing the commands or the response packet in a nonvolatile memory device.

18. The method of claim 11 including receiving one or more signals from the analyte sensor.

19. The method of claim 11 wherein the transmitting and receiving include RF communication protocol.
