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