A method of controlling an elevator system (2) comprising at least one elevator car (6), which is configured for travelling between a plurality of landings (8), comprises the steps of: displaying a hold button (26) on a mobile device (20) if the at least one elevator car (6) has stopped at a landing (8) and holding the elevator car (6) at the current landing (8) if the hold button (26) is operated.

According to one aspect, there is provided a method for predicting floor information for a destination call. The method comprises storing, in a memory, destination call history entries about destination calls made by a user, each destination call history entry comprising a time stamp and a source and destination floor pair for a destination call; detecting an intention of the user to make a new destination call; and predicting a destination floor for the new destination call based on the current time and the stored destination call history entries of the user.

Systems, methods and devices for real-time contactless elevator service operation of an elevator includes a trained neural network (TNN) model. The TNN model is trained using a training processor with augmented datasets as a synthetic training dataset, to later perform elevator identifier recognition. The augmented data sets are generated from synthetic text images, the synthetic text images are augmented with different geometrical parameters and visual parameters to a predetermined number of variations in appearance to a set of training elevator identifiers. A camera captures a user image. A text image portion from the user image is extracted using the TNN model, and detects an elevator identifier in the extracted text image portion using the extracted text image portion and the TNN model. The detected elevator identifier is displayed for user confirmation or user cancellation, and upon user confirmation, generates a control command based the detected elevator identifier associated with an elevator service.

A car mover for autonomously moving an elevator car along a lane in a hoistway, including: first and second wheels of the car mover, configured to apply a pinch force against a track therebetween and to rotationally drive along the track, by respective first and second wheel motors of the car mover; and a controller configured to execute: a gap control self-learning module, wherein based on adjustment data, one or more operational parameters applied by one or more of the first and second wheel motors are adjusted; and a gap feedback control module, wherein based on one or more of a first lateral clearance adjacent the first wheel on the track and a second lateral clearance adjacent the second wheel on the track, torque applied by one or more of the first and second wheel motors is increased or decreased.

Embodiments of systems and methods for digital control of elevator and other access gateways are described herein. More specifically, embodiments comprise systems and methods for retrofitting or outfitting elevator systems with digital control systems that can be universally applied to virtually every manufacturer's elevator systems.

The invention allows enhancing radio signal coverage in an elevator environment. An elevator antenna pair comprises a primary antenna that is configured to transmit and receive radio frequency signals with an external wireless communication network. The elevator antenna pair further comprises a secondary antenna that is communicatively connected to the primary antenna and configured to transmit and receive radio frequency signals with at least one radio frequency transceiver in an elevator car. The primary antenna is arranged within an elevator landing signalization unit, and the secondary antenna is arranged inside an elevator hoistway.

A method and a device for outputting an audible voice message in an elevator system includes at least the following steps: transmitting the content of the voice message as a text file to be output via the Internet to a web-based text-to-speech service provider; receiving an audio file from the service provider via the Internet, the audio file having been created based upon the transmitted text file to be output; and outputting the audio file in the elevator system as the audible voice message. If necessary, the text file to be output can be obtained by translating a source language text file into a target language beforehand with the aid of a translation service provider. The targeted use of online service providers allows the outlay needed to realize voice announcements in an elevator system at different use locations with different languages to be greatly reduced.

A building management robot includes a communication unit configured to recognize an identification device corresponding to a first divided space among at least one divided space in a building and acquire first identification information of the first divided space from the identification device, a camera configured to acquire image data including a position where the identification device is recognized, and a processor configured to recognize a user from the image data, confirm an authentication level of the first divided space of the recognized user from a database, and provide the user with a service based on the confirmed authentication level.

Various embodiments are directed to an elevator positioning system, comprising: a transceiver disposed within an elevator shaft; a first positioning element; a second positioning element; and a controller communicably coupled to the transceiver, wherein the controller is configured to: determine a first distance between the transceiver and the first positioning element; determine a calibration distance between the transceiver and the second positioning element based at least in part on a second reflection detected by the transceiver from the second positioning element at a first instance; based at least in part on the first distance and the calibration distance, calculate an adjusted elevator car position defined at least in part by a shaft displacement compensation distance; and cause an elevator car to move about a vertical axis of the elevator shaft to a vertical position within the elevator shaft that corresponds at least in part to the adjusted elevator car position.

A smooth braking control method for an elevator, a smooth braking control device for an elevator, and an elevator brake. The elevator is provided with an elevator brake including a fixed part and a moving part, and in a first state, by driving the moving part to move toward an elevator power device so that a friction member in the moving part contacts the elevator power device, the elevator brake provides a braking force to stop an elevator car, and in a second state, by outputting an electromagnetic force from an electromagnetic member in the fixed part, the friction member is disengaged from the contact with the elevator power device.
