Abstract
L'INVENTION CONCERNE L'HORLOGERIE. UN CIRCUIT DETECTEUR DE TEMPERATURE POUR UNE MONTRE COMPREND NOTAMMENT UN CIRCUIT 102 QUI FOURNIT UN SIGNAL DE SORTIE NUMERIQUE 106 DONT LA VALEUR EST FONCTION DE LA TEMPERATURE. CE SIGNAL EST APPLIQUE A UN COMPARATEUR 103 QUI RECOIT EGALEMENT LE SIGNAL DE SORTIE D'UN CIRCUIT 101 QUI COMPORTE UN COMPTEUR ET QUI EST ATTAQUE PAR LE SIGNAL DE SORTIE DU COMPARATEUR. ON OBTIENT AINSI UN SIGNAL DE SORTIE 109 QUI EST FONCTION DE LA TEMPERATURE AMBIANTE. APPLICATION AUX MONTRES ELECTRONIQUES.
