A method of predicting deterioration in a component part of a passenger moving system includes, activating at least one sensor in communication with the component part, performing data acquisition to acquire data from the at least one sensor, processing the data, repeating the processing step over a first specified time period, and triggering a command signal to initiate a maintenance operation and generating a predictive alert, both in response to the processed data reaching a pre-determined threshold.

In order to provide a technique capable of presenting information that is different from the image of a surveillance camera and is effective for searching for a person, this search information providing device includes, as functional units, a collation unit and an output unit. The collation unit collates a fingerprint image obtained by a fingerprint photographing device with a fingerprint image, of a search target person, given in advance. When the fingerprint image on the handrail member matches the fingerprint image of the search target person, the output unit outputs information indicating that the search target person has been detected to a predetermined reporting destination.

Disclosed is an uncoated passenger contact component including a self-sanitizing polymer composition.

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°.

A passenger transport system includes a three-phase drive motor, a control device and an inverter module having power semiconductor switches. The gate electrodes of the power semiconductor switches are driven directly by the control device. The inverter module is connected on the input side to a DC source and on the output side to the three-phase drive motor. Between the DC source and the inverter module there is a DC circuit, wherein drive signals that can be modulated on the DC circuit can be generated by the control device, and the inverter module has a demodulator, by which demodulator the drive signals can be converted into control voltages assigned to the individual gate electrodes of the power semiconductor switches.

The invention relates to a moving walk having an endless conveyor member comprising pallets and at least one longitudinal drive member to which the pallets are connected, which drive member is engaged by a drive unit, whereby the endless conveyor member runs in a middle section of the moving walk along an upper conveying track and along a lower return track; at both ends of the middle section a respective end section is located, whereby each end section comprises an entrance/exit area of the moving walk and a transfer means for transferring the endless conveyer member from the conveyor track to the return track and vice versa. The middle section comprises a self-supporting support structure, wherein the support structure is formed by roller rails, by cross beams and by support brackets, whereby the roller rails have an upper rail surface for rollers of the pallets, the cross beams connect the roller rails and/or the support brackets on both sides of the moving walk and the support brackets comprise the footing of the support structure and are spaced apart in the longitudinal direction of the roller rails and wherein the roller rails and/or the cross beams are mounted to the support brackets. This space saving support structure is easy to deliver to the building site and easy to install.
