Abstract: A system for elevator door sensor fusion, fault detection, and service notification is provided. The system includes a processor and a memory including computer-executable instructions that, when executed by the processor, cause the processor to perform operations. The operations include monitoring outputs of a plurality of sensors. It is determined whether the outputs of the plurality of sensors follow an expected pattern. Based at least in part on determining that the outputs of the plurality of sensors do not follow the expected pattern: identifying a sensor in the plurality of sensors that is not following the expected pattern, and transmitting a notification indicating that the sensor is exhibiting unexpected behaviour.

Abstract: A method and system for controlling a movable door associated with a passenger compartment, the door moveable between an opened position and a closed position configured to provide access to, or egress from, the passenger compartment. The method includes monitoring a landing area of the elevator door with at least one sensor, and determining a level of urgency of an approaching passenger based on the information from the at least one sensor. If the level of urgency exceeds a predetermined threshold, modifying a closing of the elevator door based on the level of urgency. The method may also include modifying a closing speed of the elevator door if the level of urgency exceeds a predetermined threshold.

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.

Abstract: A door control system is provided. Aspects includes a sensor having a field of view in proximity to a door threshold of an entrance to an occupancy area, wherein the sensor is adapted to detect objects in the door threshold and a landing area proximate to the door threshold, wherein the sensor is operated based on a movement of a door in the door threshold. And based at least upon detecting an object within a portion of the door threshold or the landing area, the sensor operable to signal a door operation controller to perform an action.

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.
