1. A method, comprising:

  • providing a signal associated with initiation of an analyte sensor, the analyte sensor for monitoring analyte level;

    providing a count, wherein the count is temporally associated with the signal associated with the initiation of the analyte sensor;

    periodically incrementing the count;

    storing the count temporally associated with the signal associated with the initiation of the analyte sensor, wherein when sensor life of the initiated analyte sensor has not expired and a system failure is detected, continuing use of the initiated analyte sensor based at least in part on the stored count;

    providing a new sensor count; and

    incrementing the new sensor count only when a new sensor is first initiated.
