CA 2509669

Disclosed are systems and methods for operating a barrier. In one embodiment, a door operator can be opened or closed by triggering either an internal device (e.g., wall button) or an external device. In one embodiment, if an obstacle is detected when the door is opening or closing, the door will either stop or swing in the reverse direction. In yet a further embodiment, the door operator is implemented using an alternating current (AC) synchronous motor.

L'invention concerne des systèmes et des méthodes pour actionner une barrière. Dans un mode de réalisation de l'invention, un actionneur de porte peut être ouvert ou fermé, par le déclenchement d'un dispositif intérieur (par exemple, un bouton mural) ou d'un dispositif extérieur. Dans un autre mode de réalisation de l'invention, si un obstacle est détecté, lorsque la porte est en cours d'ouverture ou de fermeture, la porte s'arrête ou se met à se déplacer dans la direction inverse. Dans encore un autre mode de réalisation de l'invention, l'actionneur de porte est actionné au moyen d'un moteur synchrone à courant alternatif (CA).
