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.

Abstract: In an elevator installation, an elevator control system is configured to receive an elevator call from a person via a call terminal and from a robot via a radio transceiver. A current transport capacity of the elevator installation is determined. An elevator call originating from the robot is recognized by the elevator control system, the call including a priority level set by a dispatcher, wherein the priority level is one of a high, a medium and a low priority range, wherein the elevator call is indicative of a boarding floor. The allocation of the elevator call originating from the robot to the elevator car is delayed if the priority level is set to the medium priority range and the current transport capacity is lower than a first threshold value, or if the priority level is set to the low priority range and the current transport capacity is lower than a second threshold value.

Abstract: A method for controlling a closing movement of a door of an elevator car in the event of a power failure uses the door drive and an electrical energy store. During normal operation of the door by the door drive, electrical energy is buffered in the energy store. In response to a power failure when the door is open, a closing mechanism begins to close the door and the stored electrical energy is provided as backup energy to the door drive by a control device to decelerate the closing movement.
