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

12. An analyte monitoring and management system, comprising:

an analyte sensor;

a transmitter unit coupled to the analyte sensor and configured to receive one or more analyte related signals from the analyte sensor; and

a receiver unit configured to receive data corresponding to the one or more analyte related signals and to process the received data, the receiver unit comprising a data analysis module including a first processing unit for performing a first predetermined processing routine, a user interface module operatively coupled to the data analysis module and including a second processing unit for performing a second predetermined processing routine, and a communication module operatively coupled to the user interface module and including a third processing unit for performing a third predetermined processing routine, wherein the first, second and third predetermined processing routines are substantially non-overlapping.

1. A data receiver unit, comprising:

a first processing unit configured to perform a first predetermined routine including generating a predetermined signal prior to a data reception period; and

a second processing unit operatively coupled to the first processing unit, the second processing unit configured to receive the predetermined signal and to perform a second predetermined routine including;

completing a first processing cycle and subsequently entering an inactive mode if the predetermined signal is received during the first processing cycle;

or

entering into an active mode and determining whether a second processing cycle is to be performed during the impending data reception period if the predetermined signal is received other than during the first processing cycle.

2. The data receiver unit of claim 1, wherein the second predetermined routine further includes, upon entering into the active mode:

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

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

3. The data receiver unit of claim 2, further comprising a timer, wherein the generated time flag is provided to the timer and wherein the second processor is maintained in the inactive mode during the data reception period.

4. The data receiver unit of claim 1, further comprising a third processing unit operatively coupled to the second processing unit, the third processing unit configured to perform a third predetermined routine.

5. The data receiver unit of claim 4, further comprising a power supply unit operatively coupled to the second processing unit, wherein the power supply unit is configured to provide power to the first, the second and the third processing units.

6. The data receiver unit of claim 5, further comprising a memory unit operatively coupled to the second processing unit.

7. The data receiver unit of claim 6, wherein the memory unit includes a non-volatile memory.

8. The data receiver unit of claim 7, wherein the memory unit is configured to store one or more programming instructions for execution by one or more of the first processing unit, the second processing unit and the third processing unit.

9. The data receiver unit claim 1, wherein the data receiver unit is configured to receive data related to one or more analyte levels during the data reception period.

10. The data receiver unit claim 9, wherein the data receiver is configured to receive data from a transmitter unit coupled to an analyte sensor.

11. The data receiver unit of claim 1, wherein the second processing cycle includes a housekeeping routine.

13. The analyte monitoring and management system of claim 12, wherein the receiver unit is configured to receive data from the transmitter unit during a data reception cycle and wherein, prior to the data reception cycle, the data analysis module is configured to generate a quiet host signal and, in response to the quiet host signal, the user interface module is configured to enter an inactive mode.

14. The analyte monitoring and management system of claim 13, wherein the inactive mode includes suspending all activity of the communication module.

15. The analyte monitoring and management system of claim 12, wherein the data analysis module is configured to receive the one or more analyte related signals for processing.

16. The analyte monitoring and management system of claim 12, wherein the user interface module includes an output unit configured to output one or more signals associated with a condition of a patient.

17. The analyte monitoring and management system of claim 16, wherein the output unit is configured to output one or more of a visual, auditory or vibratory output associated with the condition of the patient.

18. The analyte monitoring and management system of claim 12, wherein the user interface module includes an input unit configured to receive one or more input commands from a patient.

20. The analyte monitoring and management system of claim 12, wherein the analyte sensor includes a glucose sensor.

21. The analyte monitoring and management system of claim 12, further comprising an infusion device for administering a medication to a patient, the infusion device configured to receive processed data from the receiver unit.

22. The analyte monitoring and management system of claim 21, wherein the analyte sensor includes a glucose sensor and the infusion device includes an insulin infusion pump.

18-1. The analyte monitoring and management system of claim 12, wherein the communication module includes a wireless communication module.
