First Claim
Patent Images
1. A method of operating an analyte monitoring system comprising:
- providing a signal associated with initiation of an analyte sensor;
providing a count from an incrementing counter, wherein the count is temporarily 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 from a new sensor counter; and
incrementing the new sensor count only when a new sensor is first initiated, wherein the new sensor count indicates the number of sensors used.

24. A method of operating an analyte monitoring system comprising:
-
providing a signal associated with initiation of an analyte sensor; providing a count from an incrementing counter, wherein the count is temporarily associated with the initiation of the sensor signal; storing the count temporally associated with the initiation of the sensor signal in a memory device; incrementing the count by a periodic cycle of analyte level measurement; determining elapsed or remaining time of the analyte sensor by comparing the stored count with the incremented count;
wherein when the elapsed or remaining time of the analyte sensor is determined to not have expired and a system failure is detected, continuing use of the analyte sensor based at least in part on the count;providing a new sensor count from a new sensor counter; and incrementing the new sensor count only when a new sensor is first initiated, wherein the new sensor count indicates the total number of sensors used. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)
