Abstract
Official abstract text for this publication.
A method of estimating a temperature of a material being heated is described. The method may comprise supplying electrical power to a heating element in dependence on a measured temperature, calculating a rate at which the amount of electrical power supplied changes over time, comparing the calculated rate with a plurality of known values in order to determine the value of a parameter relating to thermal properties of the material being heated, and calculating an estimated temperature based on the determined value of said parameter. In some embodiments, the method may further comprise detecting a drop in temperature of the material being heated, by detecting a change in the calculated rate at which the amount of electrical power supplied changes over time.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of estimating a temperature of a material in a container being heated by a heating element, the method comprising: sensing a temperature proximate the heating element; controlling a varying supply of electrical power to the heating element to maintain a predetermined dependence of the electrical power supplied on the sensed temperature; calculating a rate at which the supplied electrical power varies with time; determining a thermal iner…
