`ABSTRACT
`
`Provided are methods and apparatus for receiving sensor
`data from an analyte sensor of a sensor monitoring system,
`processing the received sensor data with time corresponding
`calibration data, outputting the processed sensor data,
`detecting one or more adverse conditions associated with the
`sensor monitoring system, disabling the output of the sensor
`data during the adverse condition time period, determining
`that the one or more detected adverse conditions is no longer
`present in the sensor monitoring system, retrieving the
`sensor data during the adverse condition time period, pro(cid:173)
`cessing the retrieved sensor data during the adverse condi(cid:173)
`tion time period, and outputting the processed retrieved
`sensor data.
