Application: Retrospective sensor systems, devices, and methods (Patent ID: US20230360799A1)

The patent by Medtronic Plc describes a method for retrospectively calibrating a glucose sensor by using stored values of measured working electrode current to calculate a final sensor glucose value. The process involves preprocessing the Isig values, applying discrete wavelet decomposition, and utilizing machine learning models like Genetic Programming and Regression Decision Tree to calculate SG values based on Isig values and wavelet decomposition. Additionally, other inputs such as counter electrode voltage and Electrochemical Impedance Spectroscopy data can be used. Multiple machine learning models can be employed to generate respective SG values, which are then fused to create a final SG value. The fused SG values can be filtered for data smoothing and blanked if necessary.

The method outlined in the patent involves measuring Isig values for the working electrode, storing them, preprocessing them, and decomposing them using wavelet decomposition. Machine learning models like Genetic Programming and Regression Decision Tree are used to calculate final SG values based on Isig values and wavelet decomposition. The patent also discusses the fusion of multiple SG values, the use of Electrochemical Impedance Spectroscopy data, and the smoothing of EIS-based parameters. The process can be repeated periodically or continuously to generate a stream of fused SG values over time, which can be further smoothed and blanked based on noise levels or specific parameters. Additionally, the method includes smoothing the preprocessed Isig values using a polynomial model and calculating signal noise for the smoothed Isig values.
