Abstract
A sensing edge is made in segments that can be used to determine at which point along the edge an obstruction occurred. Data collected can be used to determine a point in a process that the fault occurred by addressing each segment individually or as a whole. A programmable controller can be operatively coupled to the sensing edge, and can include logic to control the door and/or other equipment using data collected from the sensing edge.
Claims7
A safety edge system, comprising
- a safety edge including
- a segment retainer,
- a grounding retainer, and
- an isolating insert disposed between the segment retainer and the grounding retainer;
- wherein the segment retainer includes a plurality of segment substrates arranged longitudinally across the segment retainer, each segment substrate is imprinted with conductive ink and connected to a conductive wire;
- wherein the grounding retainer includes a continuous surface imprinted with conductive ink;
- and
- wherein the isolating insert includes a plurality of openings corresponding to the segment substrates, forming air gaps between the segment retainer and the grounding retainer;
- and
- a controller operatively connected to the segment substrates,
- wherein, responsive to application of a force through the grounding retainer and the isolating insert, the controller is able to identify a location along the length of the safety edge where the force was applied;
- and
- wherein conductive traces are imprinted individually to each segment substrate connecting the segment substrates to a connector with a multi-conductor cable, said connector further connecting the conductive traces to individual wire conductors, said wire conductors connecting to the controller.
