Abstract: An elevator system control system is provided and includes a sensor system configured to sense elevator car conditions, a safety system signaling element to generate a safety signal indicative of an incident and a control system configured to react to the safety system signal. When the control system receives the safety signal indicating that an incident has occurred that requires engagement of at least one of primary and secondary brakes, the control system controls a deceleration rate during the incident by operating the primary brake, determining whether the deceleration rate is within a target range and adjusting the deceleration rate based on signals from the sensor system.

Abstract: A method of operating an elevator system including: receiving an evacuation call from a first evacuation floor; moving an elevator car to the first evacuation floor; opening doors of the elevator car when the elevator car arrives at the first evacuation floor; monitoring, using a sensor system, a remaining capacity of the elevator car; and closing the doors of the elevator car when at least one of a first selected period of time has passed and the remaining capacity is equal to a selected remaining capacity.

Abstract: Elevator systems having an elevator machine connected to an elevator car within an elevator shaft, the elevator shaft including a plurality of landings, at least one first sensor assembly attached to the elevator car, at least one second sensor assembly arranged within the elevator shaft and configured to interact with the at least one first sensor assembly, and a computing system in communication with at least one of the at least one first sensor assemblies and the at least one second sensor assemblies such that the computing system receives at least one of signals or data from the at least one of the at least one first sensor assemblies and the at least one second sensor assemblies. The at least one first sensor assemblies and the at least one second sensor assemblies form a contactless position sensing system for determining a position of the elevator car within the elevator shaft.

Abstract: Methods and systems of controlling elevators including detecting a landing stop for an elevator car, measuring load information associated with the stop, controlling stopping of the elevator at the landing using a machine based on at least one of the detected landing and the measured load information and performing dynamic compensation control of a motion state of the elevator with a computing system and the elevator machine. The dynamic compensation control includes receiving motion state information related to at least one motion state of the elevator car at the computing system, receiving the landing and load information at the computing system, applying a filter to the received information and generating a first control signal, and producing a control output from the first control signal to control the elevator machine to minimize oscillations, vibrations, excessive position deflections, and/or bounce of the elevator car at the detected landing.

Abstract: A method of operating an elevator building system is provided. The method includes: receiving an evacuation call from a first evacuation floor; determining an evacuation zone surrounding the first evacuation floor; determining a number of passengers on each floor within the evacuation zone; determining a number of elevator cars to send to each floor within the evacuation zone in response to the number of passengers on each floor, a capacity of each elevator car, and a location of the floor in reference to the first evacuation floor; and moving an elevator car to a first determined floor within the evacuation zone.
