Abstract: An elevator system including at least one elevator car mounted in a building to serve the floors therein. The elevator car includes a door having one or more panels, and a door operator which selectively operates the door at the end of a run from the closed to a fully open position, or from the closed to a predetermined partially open position. Door control, in response to at least one predetermined parameter of the elevator system, controls the selection by the door operator. In a preferred embodiment, an audible message informs the passengers of the decision, at least when the doors will only be partially opened.

Abstract: A braking system for transportation apparatus, such as an escalator, having an electrical drive. The braking effort applied when the transportation apparatus is to be stopped is inversely proportional to the electrical energy being consumed by the electrical drive at the time the stopping decision is made.
