    a plurality of movers movably mounted on the track for moving along a path;

    active and reactive elements associated with the track and movers and configured for driving and controlling the position of the movers along the path;

    a controller operably associated with the active elements for controlling the driving of the movers; and

    a position sensor configured for sensing position information corresponding to the true absolute position of the movers along the path;

    wherein the sensor is associated with the controller for transmitting the position information to the controller, the sensor being configured such that position formation is transmitted from the movers through substantially the entire sensor at a sensing speed faster than about 10,000 meters per second, and the controller is configured for controlling the movement of at least one of the movers independently from the others.
