Abstract
The next destination for an automatically registered elevator call is displayed to a passenger on a portable card that he carries, when he passes a beacon adjacent to the elevator, only if the destination is designated as "fixed"; if the destination is designated as "unfixed", a new next destination is determined from a record of the passenger's destinations (which may include a history of the passenger's travel habits) and the floor upon which the beacon is situated. A transponder remote from the elevator entrance responds to a transmission from the card to register a hall call for that floor; a transponder in the car can sense a transmission from the card to enter a car call for the destination floor; if there is no car transponder, the destination is stored and a car call entered automatically upon the arrival of a car in response to the hall call. If the passenger enters a new destination, it is designated as "fixed". Whenever a car call is entered for the passenger, the destination is redesignated as "unfixed". Destinations may be determined and designated centrally for all passengers, or in a distributed fashion by each corresponding card.
