A thermometer system and method that rapidly predict body temperature based on the temperature signals received from a temperature sensing probe when it comes into contact with the body. A nonlinear, multi-parameter curve fitting process is performed and depending on the errors in the curve fit, parameters are changed or a prediction of the temperature is made. Criteria exist for the differences between the curve fit and the temperature data. The processor switches to a Continuous Monitor State if the curve fit over a limited number of time frames is unacceptable. Determining the start time on which the measurement time frame for prediction is based is performed by tissue contact threshold coupled with a prediction time delay.

Cette invention concerne un système de thermomètre et un procédé correspondant qui permettent de prévoir rapidement la température du corps sur la base des signaux de température reçus en provenance d'une sonde de détection de température, venant en contact avec ledit corps. A cet effet, on applique un processus d'ajustement de courbe non linéaire multiparamètre et, en fonction des erreurs de l'ajustement de courbe, on modifie les paramètres ou on réalise une prévision de température. Des critères sont appliqués pour les différences entre l'ajustement de courbe et les données de température. Le processeur passe à un état de monitoring continu, lorsque l'ajustement de courbe supérieur à un nombre limité de tranches de temps est inacceptable. On détermine le moment de départ sur lequel est basé la tranche de temps de mesure pour la prévision, en associant un seuil de contact de tissu avec un délai de prévision.
