  "abstract": "A zoned vacuum gripping tool comprising one mounting flange, one foam pad, one ejector, two zone branches, two pressure sensors and one vent valve. When the foam pad reaches the workpiece, the foam pad is evacuated by the ejector. After the workpiece has reached the set-down position, the vacuum circuit is vented by the vent valve. The arrangement is a proposed configuration composed from a typed library of mechanism blocks derived from published patents; it has not been constructed.",
