Abstract
Se usa informacion de pulsos variables para controlar al menos una deteccion de obstaculo y tambien, de manera opcional, velocidad de movimiento de una barrera movible. En una forma de realizacion, de acuerdo con un modo de aprendizaje (50), la barrera movible es movida (51) y, mientras se esta moviendo la barrera movible, se mide (52) al menos un pulso variable que corresponde al movimiento de la barrera movible a una velocidad deseada y se usa para determinar al menos un umbral predeterminado que corresponde a un nivel de fuerza excesiva, como se ejerce por la barrera movible. Este umbral puede entonces ser usado durante un modo de operacion para facilitar la deteccion de obstaculos para la barrera.
