SYSTEM AND METHOD FOR AUTOMATED MOTOR ACTUATION IN RESPONSE TO A TRAVEL-LIMIT DISPLACEMENT OF A MOVABLE BARRIER

摘要

The present invention is generally a system and method for automatically actuating or controlling a movable barrier in response to a travel-limit displacement of the movable barrier, and more specifically, a movable barrier operator system configured to respond automatically to a travel-limit displacement, or change in position of a barrier's travel limit, in order to return the movable barrier to its intended position. In an exemplary embodiment, an operator may receive from one or more sensors adapted to detect any change in the travel limit position, a signal detecting a change in barrier position. In response to this signal, the operator may generate a command in order to counter-act, or push-back, the undesired movement of the barrier. In some applications, the invention provides a measure of security. In other applications, the invention provides a measure of efficiency and overall stability of a movable barrier system.
