Abstract

Method and system for providing a fault tolerant data receiver unit configured with a partitioned or separate processing units, each configured to perform a predetermined and/or specific processing associated with the one or more substantially non-overlapping functions of the data monitoring and management system is provided.

Claims

1. A method, comprising:

receiving one or more analyte related signals;

generating a quiet host signal prior to receiving the one or more analyte related signals; and

in response to the generated quiet host signal, completing a current processing cycle, if any, and entering an inactive mode during the reception of the one or more analyte related signals.

2. The method of claim 1 wherein receiving the one or more analyte related signals includes wirelessly receiving the one or more analyte related signals.

3. The method of claim 1 including transcutaneously positioning at least a portion of an analyte sensor in fluid contact with interstitial fluid under skin layer.

4. The method of claim 3 wherein the analyte includes one or more of glucose, blood, or oxygen.

5. The method of claim 1 further including receiving data associated with an analyte sample.

6. The method of claim 5 wherein the analyte sample is received from a blood glucose test strip.

7. The method of claim 5 further including processing the data associated with the analyte sample.

8. The method of claim 5 wherein the analyte sample includes a blood glucose measurement.

9. The method of claim 1 further including outputting one or more signals associated with the condition of a patient including one or more of a directional arrow indicator, a color indicator, or a monitored condition level indicator.

10. The method of claim 9 wherein outputting the one or more signals associated with the condition of the patient includes progressively increasing or decreasing an associated outputted signal over a predetermined time period.

11. A method, comprising:

performing, using a first processing unit, a first predetermined routine including generating a predetermined signal;

performing, using a second processing unit, a second predetermined routine including completing a first processing cycle and subsequently entering an inactive mode if the predetermined signal is received during a first processing cycle, or entering an active mode and determining whether a second processing cycle is to be performed during a data reception period if the predetermined signal is received other than during the first processing cycle.

12. The method of claim 11, wherein the second predetermined routine further includes:

expediting the second processing cycle, generating a time flag associated with the expedited second processing cycle, and entering the inactive mode if it is determined that the first processing cycle is to be performed during the data reception period; and

performing the second processing cycle and subsequently entering the inactive mode if it is determined that the first processing cycle is to be performed during the data reception period.

13. The method of claim 12, further including providing the generated time flag and maintaining the second processing unit in the inactive mode during the data reception period.

14. The method of claim 11, further comprising performing, using a third processing unit, a third predetermined routine.

15. The method of claim 11, wherein the second processing cycle includes a housekeeping routine.

16. A method, comprising:

receiving one or more analyte related signals from an analyte sensor;

performing, using a first processing unit, a first predetermined processing routine, and performing, using a second processing unit, a second predetermined processing routine, wherein the first and second predetermined processing routines are non-overlapping; and

receiving data from electronics coupled to the analyte sensor during a data reception cycle and, prior to the data reception cycle, generating a quiet host signal and, in response to the quiet host signal, placing one of the first or the second processing units in an inactive mode, wherein the inactive mode includes suspending all activity of the another one of the first or second processing units.

17. The method of claim 16, wherein receiving the one or more analyte related signals includes wirelessly receiving the one or more analyte related signals from electronics operatively coupled to the analyte sensor.

18. The method of claim 16, further comprising providing medication information based on the received one or more analyte related signals for administration to a subject.

19. The method of claim 18, wherein the medication information includes an insulin amount.
