Abstract
a. Détecteur de sens de rotation comportant un organe rotatif tournant autour d'un axe. b. Détecteur caractérisé par la combinaison d'un premier, d'un second détecteur placés autour de cet axe, chacun des détecteurs créant un signal de détection distinct ayant des états logiques correspondant aux positions de rotation de l'organe rotatif, les états logiques ayant des transitions, et un circuit logique couplé au premier détecteur et au second détecteur pour recevoir le premier et le second signal et créer des signaux de commande indiquant le sens de rotation de l'organe rotatif.
