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; andincrementing the new sensor count only when a new sensor is first initiated. 2. The method of claim 1, wherein incrementing the count is associated with a measurement cycle. 3. The method of claim 2, wherein the measurement cycle comprises a periodic determination of the monitored analyte level. 4. The method of claim 1, including storing the count temporally associated with the initiation of the analyte sensor in a memory device. 5. The method of claim 4, wherein the memory device is a nonvolatile memory device, such that count information stored in the memory is not lost during the system failure. 6. The method of claim 1, wherein the system failure is a component failure. 7. The method of claim 1, wherein the system failure includes a battery drain, power shut-down, or reset. 8. The method of claim 1, including outputting a message or alarm when the system failure occurs. 9. The method of claim 1, wherein incrementing the count is associated with communication of data packets. 10. The method of claim 1, wherein the analyte sensor comprises a working electrode that includes an analyte responsive enzyme and a mediator, wherein at least one of the analyte responsive enzyme and the mediator is chemically bonded to a polymer disposed on the working electrode, and wherein at least one of the analyte responsive enzyme and the mediator is crosslinked with the polymer. 11. A data processing device, comprising: a first counter configured to incrementally count;a data communication unit;a data processing section coupled to the data communication unit and the first counter, the data processing section configured to determine an elapsed life of an analyte sensor; wherein when a device failure is detected and the determined elapsed life indicates that analyte sensor life has not expired, continuing use of the analyte sensor based at least in part on the first counter configured to incrementally count; anda new sensor counter coupled to the data processing section and configured to increment a new sensor count only when a new sensor is first initiated. 12. The data processing device of claim 11, wherein the analyte sensor is configured to generate a signal associated with a level of monitored analyte. 13. The data processing device of claim 11, further including a storage unit configured to store a count temporally associated with initiation of the analyte sensor. 14. The data processing device of claim 11, wherein the analyte sensor includes a glucose sensor. 15. The data processing device of claim 13, wherein the data processing section is configured to compare the stored count with an incremented count associated with the first counter to determine the elapsed life of the analyte sensor. 16. The data processing device of claim 15, wherein the data processing section is configured to estimate the remaining sensor life based on the stored count and the incremented count. 17. The data processing device of claim 13, further including an output unit configured to output one or more signals associated with the count. 18. The data processing device of claim 13, wherein the analyte sensor comprises a working electrode that includes an analyte responsive enzyme and a mediator, wherein at least one of the analyte responsive enzyme and the mediator is chemically bonded to a polymer disposed on the working electrode, and wherein at least one of the analyte responsive enzyme and the mediator is crosslinked with the polymer.
