Abstract: An elevator car (100) defining an interior space (1) for accommodating passengers. The elevator car (100) comprises an openable roof (2), horizontal roof guide rails (13a, 13b) arranged on a top side of the elevator car (100), a support structure (4) pivotably mounted to the guide rails (13a, 13b) by a first joint (5a, 5b), and a working platform (6) pivotably and movably mounted to the support structure (4) by a second joint (7a, 7b) arranged at a distance from the first joint (5a, 5b). The working platform (6) is pivotable between a retracted position, in which said working platform is oriented close to the guide rails (13a, 13b) in the top side of the elevator car, and a deployed position, in which the working platform (6) is in the interior space (1), at a distance from the guide rails (13a, 13b). The first joint (5a, 5b) being arranged movable along the guide rails (13a, 13b).

Abstract: The present invention relates to computer-implemented methods and computer systems for performing reverse geocoding. The method and system of the present invention uses multiple machine learning models that are each trained to perform reverse geocoding for different geographical subdivisions across a hierarchy of such subdivisions. By chaining together multiple machine learning models across different levels of the hierarchy, latitude and longitude can be reverse geocoded with transmitting the latitude and longitude data to a remote sever, improving data security and privacy.

Abstract: An elevator car defining an interior space for accommodating passengers includes an openable roof, horizontal roof guide rails arranged on a top side of the elevator car, a support structure pivotably mounted to the guide rails by a first joint, and a working platform pivotably and movably mounted to the support structure by a second joint arranged at a distance from the first joint. The working platform is pivotable between a retracted position, in which said working platform is oriented close to the guide rails in the top side of the elevator car, and a deployed position, in which the working platform is in the interior space, at a distance from the guide rails. The first joint is arranged movable along the guide rails.

Abstract: An elevator car roof system is provided for monitoring safety of a service access located on an elevator car roof. The elevator car roof system may monitor a change in an opening state of the elevator car roof. Positions of a plurality of roof panels may indicate when the elevator car roof is partially open, fully open or fully closed. The positions of the roof panels may cause at least one sensor of the elevator car roof system to provide a signal to a control system of the elevator. Further, the elevator car roof system may detect if there is an object on the roof. Based on the detected object on the roof, the elevator car roof system may provide at least one signal to enable controlling operation of the elevator.
