Reaction Site Temperature Estimation in Blood Glucose Devices

The patent introduces a thermal model as an intermediary between the internal temperature sensor and the reaction site temperature estimation. The thermal model accounts for heat transfer paths and thermal resistance between electronic components and the reaction site, allowing accurate temperature estimation without direct thermal contact that would cause heating.

The patent replaces direct thermal measurement (mechanical/physical contact) with a computational approach using a thermal model. Instead of relying on physical proximity that causes heat transfer, the system uses mathematical modeling based on measured temperatures and known thermal characteristics to estimate the reaction site temperature.

The patent implements a dynamic thermal model that continuously adapts to changing operating conditions. The model is updated based on real-time temperature measurements from internal sensors and adjusts its parameters to reflect current device usage patterns, allowing accurate temperature estimation despite fluctuating internal temperatures from various electronic components.

The system uses feedback from internal temperature sensors to continuously refine the thermal model's estimation of reaction site temperature. The measured temperatures from various points in the device are fed back into the thermal model, which adjusts its calculations to account for current heat generation patterns, ensuring accurate temperature compensation throughout device operation.
