A movable barrier operator (10) includes an absolute position detector (124) which provides a unique value for each position of the barrier (12) along its path of travel. The absolute position detector (142) employs multiple binary serial streams and one multiple clock stream. After the first five cycles of the clock stream, the binary streams can be decoded by a processor to produce an absolute position. Every clock edge produces a new absolute position along the path of travel.
L'invention porte sur un mécanisme (10) de commande pour fermeture mobile muni d'un détecteur (124) absolu de position fournissant un chiffre unique pour chacune des position de la fermeture (12) sur sa trajectoire. Le détecteur (142) utilise deux trains binaires sériels multiples et un train de signaux d'horloge. Après les cinq premiers cycles du train de signaux d'horloge, on peut décoder les trains binaires au moyen d'un processeur pour obtenir la position absolue. Chacun des bords du signal d'horloge correspond à une nouvelle position absolue de la trajectoire de la fermeture.
