  • Method and apparatus for facilitating control of a movable barrier operator
    Patent number: 6696806
    Abstract: A movable barrier operator (11) receives movement sensing signals from a sensor (13) and calculates corresponding speed of movement of a movable barrier. Such speed measurements lead to development of a median speed value over a monitoring window. The median speed value is used in a subsequent monitoring window to facilitate determining when speed of movement for the movable barrier has slowed in a way that likely corresponds to the movable barrier having encountered an obstacle.
