Abstract: An elevator system, having: an elevator car, a hoistway, and a pit; a sensor assembly, including a sensor configured to capture and process images; an elevator safety chain; wherein the sensor assembly is configured to: monitor in first sensing mode to detect whether an object is located in a first area of the elevator system; after the object is detected in the first area in the first sensing mode, monitor in a second sensing mode that is more sensitive than the first sensing mode to detect the object in the second sensitivity mode; and upon detecting the object in the second sensitivity mode, the elevator safety chain is opened by the sensor assembly to stop the elevator car.

Abstract: An elevator system includes an elevator car, a pressure sensor, and a controller. The car is adapted to move vertically within a hoistway and defines a passenger compartment adapted to be occupied by at least one passenger. The sensor is configured to measure air pressure in the passenger compartment. The controller is configured to control travel of the elevator car, receive a plurality of pressure signals from the sensor indicative of changing air pressure in the passenger compartment over a prescribed time period, and execute a preprogrammed application configured to apply a current car velocity and the changing air pressure to a preprogrammed ear pressure table. Upon application, the controller outputs a command to reduce the current car velocity if application of the preprogrammed ear pressure table determines a differential ear pressure would otherwise exceed a preprogrammed threshold.

Abstract: Methods and systems for monitoring a dynamic compensation control system of an elevator system are provided. The methods and systems include monitoring a first motion state sensor signal generated by a first motion state sensor, the first motion state sensor associated with an elevator machine, monitoring a second motion state sensor signal generated by a second motion state sensor, the second motion state sensor located on an elevator car, determining an operational status of the second motion state sensor based on an analysis of the first motion state sensor signal and the second motion state sensor signal, and when it is determined that a failure status of the second motion state sensor is present, the method further comprises deactivating a dynamic compensation control mode of operation of the elevator system.

Abstract: Disclosed is a car mover, configured for autonomously moving an elevator car along a track beam in a hoistway lane, having: a car mover body; a drive wheel operationally connected a lateral side of the car mover body, and configured to rotate about a drive wheel axis; a first guide wheel operationally connected to the lateral side of the car mover body, wherein the first guide wheel is offset from the drive wheel so that, in operation: the first guide wheel engages a lateral sidewall of the track beam when the drive wheel laterally moves on the track beam, to thereby restrict lateral motion of the drive wheel on the track beam.

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: An illustrative example elevator rope tensioning assembly includes a tensioning sheave configured to guide movement of a compensation rope. A tensioning mass is coupled with the tensioning sheave to provide weight urging the sheave in a tensioning direction. A rail structure guides vertical movement of the tensioning mass. A frictional damper continuously resists vertical movement of the tensioning mass.
