Method and system for dynamically updating calibration parameters for an analyte sensor
First Claim
Patent Images
1. A computer implemented method, comprising:
- receiving a first sensor data at a first predetermined time from an analyte sensor in fluid contact with an interstitial fluid;
retrieving, using a processor, a previously determined rate of change of sensor data based on previously received sensor data;
updating, using the processor, the previously determined rate of change of sensor data based on the first sensor data and the previously received sensor data; and
performing, using the processor, a lag compensation of the previously received sensor data based on the updated previously determined rate of change of sensor data to generate a lag compensated previously received sensor data.

8. An apparatus, comprising;
-
one or more processing units; and a memory storing instructions which, when executed by the one or more processing units, causes the one or more processing units to receive a first sensor data at a first predetermined time from an analyte sensor in fluid contact with an interstitial fluid, to retrieve a previously determined rate of change of sensor data based on previously received sensor data, to update the previously determined rate of change of sensor data based on the first sensor data and the previously received sensor data, and to perform a lag compensation of the previously received sensor data based on the updated previously determined rate of change of sensor data to generate a lag compensated previously received sensor data. - View Dependent Claims (9, 10, 11, 12, 13, 14)
