Abstract: An elevator car separation assurance system and method of operation includes determining a position and velocity of each one of a plurality of cars by a safety motion state estimator. A safety assurance module of the system is configured to determine a separation map associated with a first car and an adjacent second car of the plurality of cars. The system is further configured to initiate a first separation assurance-induced event associated with at least one of the first and the second cars and based on the separation map. A recovery manager of the system is configured to detect the first separation assurance-induced event, and upon detection, slow at least a third car of the plurality of cars down.

Abstract: An adjacent safety configuration for an elevator includes a second pair of safeties displaced from a first pair of safeties by at least 0.1 seconds of travel time at a rated speed of the elevator. An adjacent safety configuration for an elevator including a second pair of safeties displaced from the first pair of safeties to provide a predetermined time period before the second pair of safeties pass over a point on a guide rail previously passed over by the first pair of safeties to permit the guide rail surface to decrease by a predetermined temperature. A method of spacing an adjacent safety configuration for an elevator system including de-rating a pair of trailing safeties with respect to a pair of leading safeties as a function of a rated speed of the elevator and a spacing between the pair of trailing safeties and the pair of leading safeties.

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: An elevator system includes one or more elevator cars configured to travel along a hoistway. One or more rails extend along the hoistway and are operably connected to the one or more elevator cars to guide the one or more elevator cars along the hoistway. Each rail of the one or more rails includes a plurality of rail segments arranged end to end. Each rail segment is affixed to a hoistway wall to transfer vertical loads from the rail segment to the hoistway wall. Each rail segment is secured to the hoistway wall via a plurality of rail support brackets. The vertical loads are transferred from the rail segment to the hoistway wall via at least one rail support bracket of the plurality of rail support brackets.
