Data modification for predictive operations and devices incorporating same
First Claim
1. A method of operating a device, the method comprising:
- obtaining a sequence of measurements indicative of a condition of a user;
modifying one or more unusable measurements in the sequence using one or more other measurements in the sequence to obtain a modified sequence of measurements, wherein modifying the one or more unusable measurements comprises;
determining a gap between a preceding usable measurement for the one or more unusable measurements and a succeeding usable measurement for the one or more unusable measurements;
replacing the one or more unusable measurements by interpolating the one or more unusable measurements using the preceding usable measurement in the sequence and the succeeding usable measurement when the gap is less than a threshold; and
backfilling the one or more unusable measurements with the succeeding usable measurement when the gap is greater than the threshold;
determining a predicted value for the condition based at least in part on the modified sequence of measurements; and
operating the device in a manner that is influenced by the predicted value.

Abstract
Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device capable of delivering fluid to a user involves obtaining a sequence of measurements indicative of a condition of the user that is influenced by the fluid and modifying one or more unusable measurements in the sequence using one or more other usable measurements in the sequence to obtain a modified sequence of measurements. The method continues by determining a predicted value for the condition of the user at a time in the future based at least in part on the modified sequence of measurements and operating the infusion device in a manner that is influenced by the predicted value.

8. A method of operating a device, the method comprising:
-
obtaining a sequence of measurements indicative of a condition of a user; modifying one or more unusable measurements in the sequence using one or more other measurements in the sequence to obtain a modified sequence of measurements; determining a predicted value for the condition based at least in part on the modified sequence of measurements, wherein determining the predicted value for the condition based at least in part on the modified sequence of measurements comprises; determining an estimate of a trend in the sequence of measurements based at least in part on differences between consecutive measurements of the modified sequence of measurements; and determining the predicted value for the condition of the user at a time in the future based at least in part on a current value for the condition and the estimate of the trend; and operating the device in a manner that is influenced by the predicted value. - View Dependent Claims (9, 10)

11. A method of operating an infusion device capable of delivering fluid to a user, the fluid influencing a physiological condition of the user, the method comprising:
-
obtaining a sequence of measurements indicative of the physiological condition of the user; modifying one or more unusable measurements in the sequence using one or more other measurements in the sequence to obtain a modified sequence of measurements; determining an estimate of a trend in the sequence of measurements based at least in part on differences between consecutive measurements of the modified sequence of measurements; determining a predicted value for the physiological condition of the user at a time in the future based at least in part on a current value for the physiological condition and the estimate of the trend; determining a dosage command for operating a motor of the infusion device based at least in part on the current value for the physiological condition and the predicted value for the physiological condition; and operating the motor of the infusion device to deliver the fluid in a manner that is influenced by the predicted value. - View Dependent Claims (12, 13, 14, 15, 16, 17)
