Abstract:
1. A thermometer for determining the temperature of a subject, comprising: a sensor that provides temperature signals in response to sensing the temperature of the subject, the temperature signals varying in time; a display; and a processor configured to: adapt a variable shape, nonlinear, multi-parameter model temperature curve to the monitored temperature signals, wherein the configuration of the processor in adapting the model temperature curve comprises: where: T n is an integer sample index initialized to 0 at the first sample meeting conditions for “Prediction Start”; τ is a number of seconds per sample (sec); A is an “offset” parameter (° F. or ° C.); B is a “span” or “range” parameter (° F. or ° C.); C is a “curvature” or “rate of equilibration” parameter (sec E is a “time warp” factor (unit-less) that may be used to make a nonlinear modification of the curvature of the model curve to make it better fit the curve of the temperature data; wherein the display displays the predicted temperature.
