Abstract: The disclosure relates to a method for monitoring the travel operation of a person-transporting installation with a monitoring system. The at least one motion-sensing module transmits its motion sequence images to an interaction module and to a hazard analysis module; the motion sequence images are displayed on a screen of the interaction module and, at the same time, in the hazard analysis module the motion sequence images are examined for critical situations with analysis algorithms. As soon as a critical situation is recognized, a warning signal is sent to the interaction module. As a result of the warning signal, the interaction module visually and/or acoustically emphasizes the corresponding motion sequence image on the screen and generates a confirmation input field. The travel operation of the person-transporting installation can be influenced based on a manual tapping on the confirmation input field.

Abstract: A method and a supporting-means monitoring device monitor properties of a supporting arrangement in an elevator system. The supporting arrangement has a plurality of supporting devices that support and can displace an elevator car. The method includes: measuring tensile forces acting on the supporting devices; and deriving change information indicating changes in the properties of the supporting arrangement by analyzing the progression over time of the measured tensile forces. By such an analysis, taking into consideration, for example, a temporal gradient, a frequency spectrum, and/or an amplitude of the progression over time of the measured tensile forces, there is derived e.g. information about wear on a surface profiling or a traction surface of a deflection roller or a traction sheave, information about wear on guide rails and/or information about wear of lateral guide structures on a roller for guiding one of the supporting devices.

Abstract: A method for forwarding data content from a second data connection and a third data connection of a node of a data network to a first data connection of the node, wherein data content received at the second data connection has priority over data content received at the third data connection, includes interrupting forwarding of data content received via the third data connection as soon as reception of data content at the second data connection is detected. The data content received at the second data connection is fed into an intermediate buffer (memory) and the output of the data content received via the second data connection, via the first data connection, is delayed for a definable time period.

Abstract: An elevator system includes an elevator car and a laser distance measuring device. The elevator car is moved along a travel path that is delimited at the top by an upper boundary and at the bottom by a lower boundary. The laser distance measuring device emits a laser beam and determines a distance to a position at which the laser beam impinges on an object. The laser distance measuring device is mounted on the elevator car such that the laser beam can be directed upward to the upper boundary in a first configuration and can be directed downward to the lower boundary in a second configuration. A current position of the elevator car can thereby be determined in a redundant manner. Furthermore, in a third configuration, lateral distances to boundary markers can be measured to read out information that is codified by the boundary markers.
