Patent ID: 8901940

Claim:
A sensing edge for providing a signal to a controller indicating that a forward edge of a door is obstructed during operation, the sensing edge comprising: a) an elongated sheath including: i) a first end, a second end and a first cavity connecting the first end and the second end, the elongated sheath being mounted to the forward door edge, and ii) first and second electrically conductive materials, disposed and spaced apart within the elongated sheath; b) a first end plug including: i) an inner end having first engaging structures extending therefrom, the first engaging structures positioned within the first cavity in an assembled configuration, ii) an outer end surface having a first depression for housing a resistor, the resistor electrically coupled to the first and second electrically conductive materials; and c) a second end plug including an inner end having a sensing component and second engaging structures extending therefrom, the second engaging structures positioned within the first cavity in an assembled configuration, and wherein the sensing component is electrically coupled to the first and second electrically conductive materials and is configured to detect a current flowing through the first and second electrically conductive materials and upon detecting a sudden increase in current flow, or a flow of current greater than a predetermined value, between the first and second electrically conductive materials providing a signal to a controller.
