Abstract:
In one embodiment, fuzzy sets D1-D6 indicative of the degree to which the time since the last passenger boarded an escalator can be deemed to be zero, a very long time, or something in between, are combined with fuzzy sets E1-E6 indicative of the extent to which the maximum number of passengers in a recent temporal or cyclic period can be deemed to be a zero passenger, a very large group, or something in between. In another embodiment, fuzzy sets indicative of the degree to which the time since the last passenger exited an empty escalator can be deemed to be nearly zero, a very long time, or something in between, are combined with fuzzy sets indicative of the degree to which the maximum group of passengers on the escalator at any time the last time it was empty can be deemed to be a single passenger, a very large group, or something in between. T-norms (functions for combining the pair of fuzzy sets) are used to select recommended target speeds; weighted averaging of more than one recommended target speed is used to defuzzify the result to achieve an ultimate target speed, except in the second embodiment, which tailors the speed of the escalator to the current traffic level where the target speed is always maximum if the escalator is occupied and which judiciously slows an empty escalator.

Abstract:
Elevator cabs (A,B) are transferred between elevators, which may be shuttles, in various levels of a building, such as transport floors, in response to car calls registered in the cabs and hall calls registered on the transport floors. The cabs may be transferred from carriages (107) or bogeys onto elevator car frames (104) in a lateral direction, which is perpendicular to the motion of the cab on a carriage (107) or bogey, or in a longitudinal direction which is the same as the direction of motion of a cab on a carriage or bogey. The horizontal/vertical control and transfer may be effected in response to the arrival at transport floors of elevators having cabs therein, or in response to the arrival at an elevator of a bogey carrying a cab which must be transported between a transport floor on one level of a building and a transport floor on another level of a building, in order to serve the need of a car call registered therein or a hall call. The horizontal transportation may occur on transport floors within a building, or may extend between different building segments or between different buildings.
Abstract:
An elevator system provides service between a ground level and each of three upper levels through a single elevator shuttle hoistway system. Three elevator cabs (B,D,F) are moved in a triple deck elevator car frame, or a four deck elevator car frame (75) in a low hoistway (51); two cabs (A,C) are moved in a double deck elevator car frame or four deck car frame (76) in a mid hoistway (52); and one cab (P) is moved in a single deck car frame or triple deck car frame (77) in a high hoistway (53). Other embodiments have other car frame arrangements.
Abstract:
A particular elevator is commandeered to transfer an emergency cab F to (or near) a floor where an alarm has been sounded. The commandeered car is brought to the floor FF where the emergency cab is parked. The fire cab is exchanged for the normal cab C on the commandeered car, and is then carried to (or near) the alarm floor for responding to the alarm. Passengers in the normal cab may exit through landing doorways (23). Emergency personnel have access to the alarm area through emergency hoistway doors (27). A rack and pinion horizontal motive means for moving the cabs is illustrated.
Abstract:
Elevator cabs A-C move upwardly through three or more contiguous overlapping hoistways 38-40 in the upper decks of double deck car frames 41-43, and move downwardly through the hoistways in the lower decks (or vice versa). To switch between decks, the cabs are offloaded from the hoistways into auxiliary elevators 50, 51 at the terminal ends of the shuttle, and are moved to be adjacent to the other deck by the auxiliary elevator and loaded thereon for the trip in the opposite direction. A second embodiment has additional auxiliary elevators 64, 65 and additional cabs D, E so that loading and unloading of passengers do not delay movement of the cabs in the hoistways.

Abstract:
Double deck elevator cars (10-12) are moveable in corresponding adjacent overlapping hoistways (7-9). Passengers who have entered the bottom deck (39) of a first elevator (12) from a ground landing (41) are transferred into the bottom deck (47) of a second elevator (11) as passengers in the upper deck (46) of the second elevator are transferred to the upper deck (38) of the first elevator. Passengers in the lower deck (31) of a third elevator (10) are transferred to a lower landing (33) as passengers in an upper landing (32) enter an upper deck (30) of the third elevator. Passengers are thereafter transferred in the same fashion between the second elevator and the third elevator at a second transfer level (49).
Abstract:
A remaining response time for an elevator car under consideration for assignment to a newly registered hall call is estimated by using a neural network. The neural network or any other downstream module may be standardized for use in any building by use of an upstream fixed length stop description that summarizes the state of the building at the time of the registration of the new hall call for one or more postulated paths of each and every car under consideration for answering the new hall call.
