A method for refinishing a surface structure of shaft material of an elevator, which extends along a shaft, enables the use of image data to determine an absolute position and/or speed of an elevator car. The elevator includes the elevator car, which is movable in the shaft, a camera, which is arranged at the elevator car and generates the image data from the surface structure, and an evaluating unit, which determines the absolute position and/or the speed of the elevator car from the image data. The surface structure is refinished at least locally in order to increase a distinctiveness of the surface structure in the image data. The shaft material can be, for example, a guide rail, a fastening element of the guide rail, or a shaft wall.

A safety switching for elevator systems includes a safety function and a safety switch dedicated to the safety function. The safety switch opens or closes a safety circuit between one connection point and a second connection point as a function of a safety state of the safety function. A test function tests whether or not the safety switch opens and closes the safety circuit as a function of the safety state of the safety function. A detection device is provided for the test function. An auxiliary energy function is provided wherein an auxiliary voltage can be temporarily applied via at least the safety switch and an input part of the detection device for performing the test function. Locally between the connection points the auxiliary energy function introduces an auxiliary energy for generating the auxiliary voltage. The safety switching can be used for converting or retrofitting an existing elevator system.

To provide an elevator 3D data processing device that can reduce a load of calculation. The elevator 3D data processing device includes a projection image generating unit that, when 3D data of a shaft of an elevator is aligned with a preset coordinate system, generates a 2D projection image from the 3D data, a projection image feature extracting unit that extracts a feature of the projection image generated by the projection image generating unit, and a reference position specifying unit that specifies a reference position for processing of the 3D data from the feature extracted by the projection image feature extracting unit.

A modular sill assembly includes a top layer, a bottom layer, a first fastener, and a second fastener. The top layer includes a first top plate and a second top plate. The first and second top plates define a door channel therebetween. Each of the first and second top plates includes a top surface, a bottom surface, and a blind bore. The blind bore is defined in the bottom surface and extends towards the top surface. The blind bore is threaded. The bottom layer includes a first base plate that defines a through bore. The first fastener extends through the first base plate and is threadably received in the blind bore of the first top plate to secure the first top plate to the first base plate. The second fastener extends through the first base plate and is threadably received in the blind bore of the second top plate to secure the second top plate to the first base plate.

A method and a corresponding device for exchanging a component in a passenger transport system are proposed. In this case, a digital double dataset, which is digitally stored in a computer and can also be processed, exists parallel to the passenger transport system, wherein said digital double dataset comprises data concerning physical properties of the passenger transport system. The method comprises the steps of physically exchanging the component by removing an existing component from the passenger transport system and replacing the existing component with a replacement component; and exchanging component data concerning physical properties of the component in an at least partially automated manner by replacing component data concerning physical properties of the existing component with component data concerning physical properties of the replacement component in the digital double dataset.

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.

In a method for carrying out an installation process in an elevator shaft of an elevator system, an assembly device is inserted into the elevator shaft. The assembly device includes a support component, a mechatronic installation component retained by the support component and a control apparatus. At least one assembly apparatus (tool, sensor or component) is arranged on the support component. The support component is fixed in a fixing position in the elevator shaft. After the support component has been fixed, an actual position of the at least one assembly apparatus is determined relative to the installation component. Using the determined actual position relative to the support component, the at least one assembly apparatus is received by the installation component and an assembly step is carried out using the received at least one assembly apparatus.

An exemplary method includes distributing identifying tags to a plurality of potential elevator passengers so that each passenger has a uniquely identifiable one of the tags. Collective elevator system traffic information is determined based on monitoring movement of individual ones of the plurality of tags and corresponding elevator system operation.

An elevator door subsystem including a hanger mount, a leveling cam, an engaging member, and a roller assembly, configured such that when the roller assembly is positioned on one side of the elevator door hanger, the hanger mount is positioned within an opening of the elevator door hanger, and the leveling cam is positioned on another side of the elevator door hanger, the engaging member is receivable by the roller assembly after the engaging member is passed through an opening in the leveling cam, an opening in the hanger mount, and the opening in the door hanger.

An elevator car (42; 103) for carrying a load in a vertical direction. The elevator car includes at least one elevator car door (38) carrying a door coupling (20) and a camera mount (40) comprising a mounting location (46) for a camera (44). The camera mount (40) is located at the top of the elevator car (42) with the mounting location (46) positioned for a camera (44) to monitor the door coupling (20). The camera mount is deformable at least in the vertical direction, when acted on by a downwards force, such as to protect the door coupling (20) from being impacted by the camera mount (40).
