  • Patent number: 7614490
    Abstract: A passenger conveyor handrail (30) has a gripping surface (32, 42, 52, 62, 72, 82) with a generally circular cross-section. Disclosed examples include a toothed driven surface (34, 44, 54, 64, 74, 84) that is adapted to be engaged by a toothed driving member (28) for propelling the handrail in a desired direction. Disclosed examples include having the generally circular cross-section extend along an entire length of the handrail (30) corresponding to the closed loop path followed by the handrail during operation of a corresponding passenger conveyor.

  • Patent number: 7475757
    Abstract: A perceived waiting time for a hall call to be answered by a car is determined as a constant times the square (46) of the summation (45) of remaining response time (39) and the amount of time that has expired since the call was registered (38). The time that may be perceived by a passenger to travel to the passenger's destination is determined as a constant times the square (51) of the distance between an estimated destination floor and the floor of the call and a constant times an estimated number of new hall stops and committed hall stops that each car will make (47). Perceived service time is (52) the sum of perceived wait time and perceived travel time. Constants are adjusted so that a long waiting time will yield a quick travel time. Assignment of calls to cars (60) is in accordance (61) with the smallest summation of square (59) of perceived service times for all waiting up calls and down calls.
