Abstract

Dispositif électronique à usage d'horloge et/ou de chronomètre à affichage numérique, du genre comportant un générateur de signal qui alimente, par l'intermediaire d'unités de mémoire et de decodage, une serie d'indicateurs visuels numériques. Le nombre de ces indicateurs 36-39 est inférieur au nombre minimum nécessaire pour l'affichage simultané de groupes de chiffres respectivement affectés chacun aux dizaines et unités d'heures, de minutes, de secondes et dixièmes de seconde; le dispositif comportant une unité de présélection 24 interposée entre les unités de mémoire 10, il et l'unité de décodage 35 et conçue pour permettre l'envoi en séquence préfixée auxdits indicateurs de signaux relatifs à l'un au moins desdits groupes de chiffres. Application, entre autres, aux automobiles de compétition.
