  • Noncontact lateral control system for use in a levitation-type transport system
    Patent number: 5601029
    Abstract: A noncontact lateral control system for use in a corridor guided noncontact transport system includes proximity sensors mounted on each side of the container of the transport system operable to continually monitor the lateral position of the container as the container moves through the transport system transit corridor. If the proximity sensors sense that the container has moved laterally within the transit corridor, a control unit associated with the lateral control system provides an energizing signal to one or more electromagnets and the electromagnets move the container laterally within the transit corridor until the container is again centered laterally within the transit corridor.
