The method including the steps of providing the lift car a scanning device directed outwardly from the lift car. Each of the stations having an independent scanning extension. When the lift car arrives at one of the stations equipped with a scanning device, the scanning device and the scanning extension are juxtaposed to form an operable combination. Scanning the predetermined region with the operable combination to produce an output signal representing a state of the predetermined region, such as whether the region is occupied or not. Using the signal or a function of the signal to regulate subsequent operation of the lift car.
A method of controlling a lift car located in a lift shaft, which serves to define at least two or more stations between which the lift car can be driven and at each of the at least two or more stations the lift car can be caused to stop to enable at least one of a person and an article to one of enter and leave the lift car, the method comprising the steps of:
A lift system having a lift car located in a lift shaft which serves to define a number of separate stations, the lift car being stoppable at each of the separate stations to enable a person to one of enter and leave the lift car, the lift system comprising a scanning device, supported by the lift car, and being directed outwardly of the lift car, a scanning extension at each of the separate stations at which the lift car can be stopped, and when the lift car is stopped at a given station, the scanning extension is juxtaposed with the scanning device of the given station to provide a combined unit directed at a predetermined region of the given station, and the scanning device is adapted to provide on an output signal representing a state of the predetermined region.
