Abstract: An aerodynamic bearing for mounting a shaft for a turbo compressor having two annular axial bearing disks and a hollow cylindrical radial bearing bush. The two axial bearing disks are spaced apart and form a cavity between them for receiving a shaft sleeve connected to the shaft, and the two axial bearing disks each have an axial bearing surface facing the cavity for forming an axial gas cushion in an axial bearing gap between the axial bearing surface and the shaft sleeve. The radial bearing bush has a radial bearing surface radially inward for forming a radial gas cushion in a radial bearing gap between the radial bearing surface and the shaft for the radial mounting of the shaft, and the radial bearing bush is formed integrally and/or materially with one of the axial bearing disks as a combination bearing bush.

Abstract: A turbocompressor with an impeller rotatable about an axis of rotation for conveying a fluid, a diffuser downstream of the impeller in terms of flow, and a clamping ring for fixing a thrust bearing axially mounting the impeller in a bearing receptacle. The diffuser and the clamping ring are formed integrally and in a single piece with each other as a unit.

Abstract: A connection adapter for the detachable connection of an impeller with a shaft made of ceramic or tungsten carbide, to a rotor assembly for a turbo compressor. The connection adapter has an impeller section for fixing the impeller to the connection adapter and a shaft section for fixing the connection adapter to the shaft, and the impeller section has a first axial alignment means for axial alignment and a first radial alignment means for radial alignment of the impeller to the connection adapter. The shaft section has a second axial alignment means for axial alignment and a second radial alignment means for radial alignment of the shaft to the connection adapter, by way of which the impeller and the shaft are in a predetermined axial and radial alignment to one another on the connection adapter.

Abstract: The present disclosure relates to a method (200) of updating safety-related software in a people conveyor system, particularly in an elevator system (10), the method comprising: the steps of providing an updated version of the safety-related software (210); storing (230) the updated version of the safety-related software in a safety unit (60) of the people conveyor system; activating (240) the updated version of the safety-related software, the step of activating including operating a software update activation switch permanently associated with the people conveyor system; and in case of successful activation of the updated version of the safety-related software, controlling the operation of the people conveyor system based on the updated version of the safety-related software (290).

Abstract: Embodiments are directed to receiving, by a demand entering device configured to receive an elevator destination command, a request for at least one of: statistical data regarding use of at least one elevator, and field data in connection with a field service, maintenance, repair, or installation activity associated with the at least one elevator, and obtaining, by the demand entering device, at least one of the statistical data and the field data in response to the request.

Abstract: A method includes receiving, from a portable recording device, multiple recordings of sounds made by an elevator during operation of the elevator, the multiple recordings generated at different times. The method includes analyzing, by a sound analysis circuit, the multiple recordings generated at the different times to detect changes in an elevator characteristic over time and generating, based on detecting the changes in the elevator characteristic over time, a notification to perform an action on the elevator.

Abstract: A device and method for automatically adjusting safety control parameters of a conveyor are disclosed. The safety device may include various sensors and a safety control module. The safety control module may be preprogrammed with a learn-run method configured to learn operational and mechanical characteristics of a conveyor, validate the operational characteristics of the conveyor based on predefined nominal specifications, and determine a safety function with calibrated safety control parameters by which to monitor conveyor operation.

Abstract: An access control system for a people conveyor control system, includes an authentication proving device adapted to communicate with a people conveyor control system. The authentication proving device has a central processor unit and a read protected memory protected from read and write access by external applications. The authentication proving device stores in its read protected memory program code to carry out a verification procedure in response to a verification request from the people conveyor control system, and sends a verification signal to the people conveyor control system. The people conveyor control system in response to the verification signal selectively allows or denies access to at least one of specific sections of said people conveyor control system or specific functions implemented in the people conveyor control system.
