US Patent 10163284 Method and system for controlling a movable barrier

A method and system include monitoring to detect a crossing of a first geographic boundary and monitoring to detect a crossing of a second geographic boundary. When a crossing of the first geographic boundary and a crossing of the second geographic boundary are detected in succession, a first barrier system response is initiated. In some examples, when a crossing of the third geographic boundary and a crossing of the second geographic boundary are detected in succession, a second barrier system response is initiated.
