Abstract: Embodiments include techniques for operating an elevator safety control system and method. The techniques include charging one or more portions of an elevator system, the elevator system includes an elevator door and elevator frame, and monitoring a charge on the one or more portions of the elevator system. In addition, the techniques include detecting a change in the charge on the one or more portions of the elevator system, and responsive to the detection, controlling an operation of the elevator door.

Abstract: A method of fault detection of a belt or rope includes interconnecting a plurality of cords of the belt or rope, the cords including a plurality of wires, to form a bridge circuit. A fault detection bridge circuit is subjected to a voltage excitation and outputs a voltage which is indicative of the belt or rope damage but remaining insensitive to other environmental noises.

Abstract: A method of fault detection of a belt or rope includes connecting a fault detection unit to at least a portion of a belt or rope including a plurality of wires arranged in a plurality of strands and/or cords. At least the portion of the belt or rope is subjected to an AC voltage of high frequency range and an electrical impedance of the portion of the belt or rope is measured via the fault detection unit. Using at least the measured electrical impedance of the portion of the belt or rope, a fault condition of the belt or rope is determined.
