Abstract: A method for controlling car separation in a multi-car elevator system, the method including: initiating, by a controller, a change in a profile of a target elevator car; determining that N elevators cars are affected by the change in the profile of the target elevator car, wherein elevator car N is an elevator car farthest from the target elevator car; calculating for each of the N elevator cars an updated profile; for each of the N elevator cars, beginning with the Nth elevator car and ending with the target elevator car, performing: determining if the updated profile for the elevator car will provide separation between the elevator car and a neighboring elevator car; and when the updated profile for the elevator car will provide separation between the elevator car and the neighboring elevator car, executing an elevator car profile update process for the elevator car.

Abstract: A device commissioning system includes a terminal device, a data communication network, and a network controller. The terminal devices selects a device type of a component configured to operate in a control system, and outputs a device activation signal that requests a configuration file for commissioning the component according to a selected device type. The communication network is remotely located from the component and stores configuration files for commissioning different types of components. The network controller receives the device activation signal indicating a request to commission the component according to the selected device type and establishes a secure data link to deliver the configuration file in response to the device activation signal. The component receives the configuration file corresponding to the selected device type, and installs the configuration file to commission operation as the selected device type.

Abstract: An elevator car travels in a lane (113, 115, 117) of an elevator shaft (111). A linear propulsion system imparts force to the car (214). The system includes a first part (116) mounted in the lane of the shaft and a second part (118) mounted to the elevator car configured to co-act with the first part to impart movement to the car. Car state sensors (360a-c) are disposed in the lane and determine a state space vector of the car within the lane. A sensed element (364) on the car is sensed by the plurality of car state sensors when the car is in proximity to the respective car state sensor. A control system (225) applies an electrical current to at least one of the first part and the second part and the plurality of car state sensors communicate with the control system and the linear propulsion system to provide state space vector data.

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: A service tool proximity detection system includes a service tool and an equipment controller. The service tool is operable to establish communication with the equipment controller of an equipment service system. At least one processor of the service tool proximity detection system is configured to generate a location proximity indicator to verify proximity of the service tool to a predetermined service location of the equipment service system, determine that the service tool is located local to the predetermined service location based on verifying that a response to the location proximity indicator matches an expected response, determine that the service tool is located remote from the predetermined service location based on verifying that the response to the location proximity indicator fails to match the expected response, and configure one or more functions of the service tool based on the location of the service tool relative to the predetermined service location.

Abstract: According to an aspect, an elevator system includes a propulsion system having a plurality of motor segments forming a primary portion and a plurality of drives to impart force on a secondary portion coupled to an elevator car. The elevator system also includes a controller operable to identify a local neighborhood of the drives and determine a health status of each of the drives within the local neighborhood. The controller is further operable to adjust a thrust command per active drive of the local neighborhood based on at least one of the health status and a position of each active drive of the local neighborhood with respect to the secondary portion.

Abstract: An elevator control system is configured to control an elevator car constructed and arranged to move along a hoistway defined by a stationary structure. The elevator system may include a communication pathway and a hoistway control system supported by the stationary structure and configured to send a continuous brake command signal over the pathway. A car control system is carried by the elevator car and is configured to receive the continuous brake command signal and initiate a brake Ustop mode upon a loss of the brake command signal, and independent of the hoistway control system.
