  "abstract": "A zoned vacuum gripping tool comprising one mounting flange, two suction cups, one ejector, one manifold, two zone branches, one pressure sensor and one vent valve. When the suction cups reach the workpiece, the suction cups are 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.",
