Abstract: The disclosure relates to a handrail disinfecting device for a handrail of a passenger transport installation. The handrail disinfecting device has a plurality of light-emitting diodes that can emit germicidal electromagnetic radiation in the region of their light cone. A pass-through segment of the handrail disinfecting device is divided into at least two sectors and has a carrier having planes that are arranged in the sectors. The light-emitting diodes are arranged on the carrier such that they are oriented according to the planes. In one of the sectors, there are two planes that are arranged in parallel with the longitudinal extension of the pass-through segment and so as to be mutually inclined at an angle of 100° to 160°.

Abstract: Spreadable granules as infill granules for grass and artificial turf fields are proposed, which granules have a polymer matrix with a percentage between 10% by mass and 100% by mass of at least one biodegradable polymer and at least one filler from the group of natural fillers, embedded in the polymer matrix with the at least one biodegradable polymer. The invention provides for the spreadable granules to have at least one filler from the group including comminuted fruit kernels. In addition, the invention relates to the use of such spreadable granules as infill granules for grass and artificial turf fields, as a spacer material for the storage of construction materials, such as, e.g., floor covering materials, and as grit for road maintenance in winter.

Abstract: A passenger transport system and a method of operating the same are described. The passenger transport system includes a passenger conveying device, a control unit for controlling an operation of the passenger conveying device, and a disinfecting device for disinfecting a surface to be disinfected on the passenger conveying device. The disinfecting device includes a controller for controlling an operation of the disinfecting device. The control unit of the passenger transport system and the controller of the disinfection device are adapted in such a manner that status signals, which reflect information about a current operation, a current state, and/or a current configuration of the disinfection device, are sent from the controller to the control unit, and the control unit generates control signals taking into account received status signals and transmits them to the controller, wherein the controller controls the operation of the disinfection device taking into account received control signals.

Abstract: The disclosure relates to monitoring a state of a physical passenger transport system. A method comprises monitoring the state of the passenger transport system using an updated digital-double dataset (UDDD) that reproduces in a machine-processable manner characterizing properties of components of the physical passenger transport system in an actual configuration after its assembly and installation. At least one detection device is arranged in the conveyor belt of the physical passenger transport system that detects accelerations and changes in position in all three axes during operation, which are transmitted to the virtual conveyor belt of the UDDD. Using dynamic simulations, forces, impulses and vibrations resulting from the dynamic behavior of the conveyor belt, which act on the virtual components of the virtual conveyor belt, corresponding to the physical components, and on the virtual components which interact with the virtual conveyor belt, can be determined and evaluated.

Abstract: The invention relates to a device for operating elevators in a special mode which comprises at least one control element for controlling at least one allocated functional unit of the elevator. At least one indicator is assigned to the functional unit, which indicates at least one condition of the functional unit that can be influenced by one or several control elements and which can be perceived by the operator of the one or several control elements.
