  • Patent number: 7849974
    Abstract: An elevator system (20) includes a plurality of cars (22) and destination entry devices (40) located some distance from the elevator cars (22). A controller (38) dispatches an elevator car to a requested destination entered by a passenger before the passenger enters an elevator car. In one example, the controller (38) uses an expected arrival time corresponding to the time it is expected to take for a passenger to travel from the location where the destination request is entered to the location of the elevator car to decide how to dispatch a car to service that request. In one example, the controller dispatches an elevator car to the requested destination on a next trip of that car if the expected arrival time of the passenger near that car occurs at or before the departure time for that next trip. Otherwise, the controller (38) dispatches the car to the requested destination on a subsequent trip after the next trip.

  • Publication number: 20090218176
    Abstract: Method for the condition monitoring of the safety switches of the safety circuit of an elevator. Inferences can be made about the condition of a safety switch by measuring and examining the current of the safety circuit of the elevator after the state of the safety circuit has changed. The current signal is filtered, after which the amount of interference caused by contact malfunctions of the switch is determined from it. Based on the amount of interference it is possible to determine in what condition the switch is.

  • Patent number: 7575101
    Abstract: A detector of foreign objects, and particularly fingers, between the doors and the contiguous walls of landing and car openings in an elevator with glass car and landing doors includes a light beam emitter and a receiver. The emitter, which is located near an opening frame edge of the car, emits a light beam that extends transversally across the car and landing glass doors from the vertical car opening frame edge to the opposite vertical landing frame edge. The receiver, which receives the emitted light beam, is adapted to detect any obstacle to the light beam and to order the simultaneous halt and reversal, as required, of the car and landing doors.

  • Patent number: 7575102
    Abstract: In an elevator safety device, a brake device puts brakes to brake a car through an operation of a safety relay main contact provided to a safety circuit. When the car stops during normal operations, a safety relay instruction signal for operating the relay main contact to such a direction that the brake device puts brakes is generated from a detection circuit. Then, the detection circuit detects whether or not the safety relay main contact is operated in accordance with the safety relay instruction signal.

  • Patent number: 7562747
    Abstract: An elevator installation with at least one car includes at least one device for determining a position of the car and a method of operating such an elevator installation. The position determining device has a code mark pattern and a sensor device. The code mark pattern is arranged along the length of travel of the car and consists of a multiplicity of code marks. The sensor device is mounted on the car and has sensors contactlessly scanning the code marks. The code marks are arranged in a single line and the sensor device comprises at least two sensor groups which are separated from each other perpendicular to the line of the code marks, which makes reading the code marks possible even if there are lateral displacements between the sensor device and the line of the code marks.

  • Patent number: 7559408
    Abstract: A floor selection station (39a) has at least one switch button (45-51, 70, 93) which visually handicapped people use in selecting floors, and a speaker (54) to emit a sound uniquely ndicative of which elevator to board. Stations (39a, 39c) have a plurality of buttons with Braille indications of groups of floors (45-51) or individual floors (33). A station (39b) has only one button (70). Near or at each elevator lobby related to a group of floors serving a building, a floor identifier (39, 42) identifies with color, and optionally a symbol such as letter, each floor which is served by the group of elevators related to that lobby. At each elevator (26-29) there is an elevator indicator (32-35) which displays the same color, and optionally the same symbol, as displayed for any floor which the respective elevator is currently assigned to serve, and a speaker (32a 35a) which emits the same sound as at the floor selection station until the assigned elevator is dispatched.

  • Patent number: 7559407
    Abstract: A set of elevators, preferably an elevator group, may include a number of elevators without counterweight which have a common connection to a power supply. The elevators may have a common control system which contains an instruction to prevent an elevator having stopped at a floor from being dispatched upwards if, of the elevator cars of the other elevators connected to the same power supply, more cars are moving upwards than are moving downwards at the instant and/or within a set period of time. A method for controlling a set of elevators without counterweight connected to a common power supply may include monitoring to establish whether, at the instant and/or within a set period of time, the number of upwards moving elevator cars of the elevators in the set is larger than the number of downwards moving elevator cars of the elevators in the set.

  • Patent number: 7549513
    Abstract: In an elevator control apparatus, calculations regarding the control of an elevator are performed in a duplexed system including first and second processing portions. A first clock signal from a first clock is input to the first processing portion. A second clock signal from a second clock is input to the second processing portion. The first and second clock signals are input to a clock abnormality detecting circuit. The clock abnormality detecting circuit counts the numbers of pulses of the first and second clock signals, and detects abnormalities in the first and second clock signals from a difference between the numbers of the pulses.

  • Patent number: 7546903
    Abstract: Example embodiments relate to a method and a system for integrating electric elements of an elevator in a single module, e.g. in the door operator of the elevator, to reduce the number of components to be installed and to enable the electric elements of the elevator to be added to the door operator on the elevator car already at the manufacturing stage. The method may include intergrating electric components to be placed in the elevator, such as location elements, acceleration sensors and door zone sensors, with the door operator or some other module already at the manufacturing stage of the elevator, e.g. by placing the active parts of the sensors in conjunction with the door operator and the passive parts on the floor level side.
