  • Patent number: 5207309
    Abstract: A controller for a device moving along a complementary path to a conveyed object, derives basic speed input from the object conveyor and uses a non-invasive sensor system to detect the proximity of the object. The sensor system controls electronic logic which causes a drive unit to match the speed of the device to that of the object over the complementary path. The controller returns the device to the start of the path for iterative utilization.
