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 escalator system includes a moving step including a plurality of grooves and drivable in a travel direction. A combplate is located at at least a downstream end of the moving step relative to the travel direction at a step-combplate interface. A retraction device is configured to move the combplate along the travel direction from a normal position toward a retracted position when an entrapment of an object is detected at the step-combplate interface.

Abstract: A multi-car ropeless elevator system includes at least one lane. An elevator car is arranged in the at least one lane. A linear motor system includes a plurality of stationary motor primary sections extending along the at least one lane and at least one moveable motor secondary section mounted to the elevator car. A plurality of sensors is operatively connected to the linear motor system. Each of the plurality of sensors is operatively associated with a corresponding one of the plurality of stationary motor primary sections. A sensor failure detection and fusion system is operatively connected to each of the plurality of sensors. The sensor failure detection and fusion system operates to identify failures in one or more of the plurality of sensors and fuse data received from remaining ones of the plurality of sensors.

Abstract: An escalator system is provided and includes a balustrade including a skirt with a brush, a moving step, which is drivable to move in a conveyance direction along the balustrade to form a step-skirt interface between ends of the brush of the skirt and a corresponding side of the moving step, and an entrapment monitoring and detection system. The entrapment monitoring and detection system includes a sensor and a processor. The sensor is disposed at the step-skirt interface and is configured to sense an object being present at the step-skirt interface. The processor is configured to determine whether the sensor senses the object being present at the step-skirt interface for a predetermined time.

Abstract: An elevator component separation assurance system includes a controller, and a brake controller. The controller includes an electronic processor, a computer readable storage medium, a safety motion state estimator, and a safety assurance module. The safety motion state estimator is configured to identify velocity and position of each one of a plurality of elevator components. The safety assurance module is configured to select a separation map from a plurality of pre-pre-programmed separation maps for each one of an adjacent component pair of the plurality of elevator components for initiating a Ustop that maintains elevator component separation. The brake controller is carried by each one of the plurality of elevator components, and is configured to actuate a secondary brake upon detection of a loss of communication with at least a portion of the controller.

Abstract: An elevator system includes a lane and at least one rail extending along the lane. An elevator car is arranged in the lane and is operatively coupled to the at least one rail. The elevator car has a predetermined alignment relative to the at least one rail. A propulsion system is operatively connected between the elevator car and the at least one rail. A thrust and moment control system is operatively connected to the propulsion system. The thrust and moment control system selectively controls the propulsion system to substantially maintain the predetermined alignment of the elevator car relative to the at least one rail.
