  • Patent number: 8564851
    Abstract: Upper to lower assembly analog position sensors in a dual scanning system measure alignment offsets. A controller uses error signals from the position sensors to calculate actuator error profiles that are used in the next scan in the same direction, with different error profiles being used for forward and reverse scans. Since the alignment error profiles are repeatable for a given set of scanner conditions, the actuator controller anticipates what the error signal will be before each scanning assembly reaches a given position. An optimized error correction can be calculated based on the error profiles and actuator bandwidth without concerns regarding feedback loop speed, overshoot, and unstable control oscillations. An actuation system driven from error profiles can correct for alignment offsets by actively changing belt tensions at the offsetting drive pulleys and/or changing the position of sensor assemblies relative to the drive belt systems.

  • Patent number: 8196516
    Abstract: A sensor head-transporting roller carriage has four pairs of wheels acting around pivot points at the four corners of the carriage, which is advanced along tracks that are supported by vertical structures. The lateral wheel spacing is chosen in correlation with the track support interval distances such that the vertical travel of all the wheels together is averaged, to be zero. As a result, variations in displacement alignment of the sensor are minimized. In addition, the pivot mechanism results in a fifty percent reduction in the effect of random vertical deflections caused by track debris or wheel concentricity etc. versus standard non-pivoting wheel sets. The roller carriage moves the sensor head along the cross direction to monitoring physical characteristics of a web of material that is moving in the machine direction.
