Abstract
A method and system for monitoring a movable partition. In one embodiment, the system includes a sensor linked to a movable partition, a drive system, and a controller. The drive system is configured to move the movable partition. The sensor, which in one embodiment includes a drum connected to the partition by a cable, is independent of the drive system. The sensor transmits a signal indicative of the rotational motion of the drum to the controller, which receives the transmitted signal and calculates at least one of a speed, acceleration, position, and direction of movement of the movable partition.
