Abstract:
1. A method of estimating the temperature of a reaction site on a measurement strip in a blood glucose measuring device having a plurality of heat generating components and a temperature measuring element, the method comprising: determining, by a microcontroller, an activation initiation time, when a heat generating element becomes active, an activation duration time, how long a heat generating element had been active within a sample period, and a thermal magnitude Qx at which a heat generating element had been active within the sample period for each of the heat generating components; determining, by a microcontroller, a temperature elevation Ex for each of the heat generating components, wherein the temperature elevation Ex for each of the heat generating components is determined at least in part by an impulse response matrix [X determining, by a microcontroller, a total temperature elevation E reading, by a microcontroller, a temperature value T determining, by a microcontroller, a reaction site temperature estimation T
