  "abstract": "A zoned vacuum gripping tool comprising one mounting flange, one foam pad, one ejector, four isolation valves, four zone branches, one contact detector and one blow-off 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 workpiece is blown off by the blow-off 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.",
