MOVABLE BARRIER OPERATOR COMPRESSED INFORMATION METHOD AND APPARATUS

摘要

System (20) of figure 2 having a movable barrier (21) that serves to selectively control the movement of a movable barrier (22). The movable barrier controller (21) can selectively move the movable barrier back and forth between a fully opened position and a fully closed position. At least one movable barrier force sensor (23) responds to indicia of force as applie d to the movable barrier (22) and provides corresponding force information to the movable barrier controller (21). A position sensor to determine a presen t position of the movable barrier. A movable barrier controller (21) can obtai n readings from the movable barrier force sensor (23) during controlled moveme nt of the movable barrier (22) to develop applied force information for various positions of the movable barrier during movement thereof.
