Patent number: 8177036Abstract: Elevator reassignment information is communicated to passengers in a group elevator system (10). The group elevator system (10) includes a group of elevators (14a, 14b, 14c) that is operable to transport each of the passengers to one of a plurality of floors (L, F2, F3, F4, F5). A destination entry input device (30, 35) at each floor permits each passenger to enter destination input information. A dispatch controller (20) assigns an elevator to each passenger based on the destination input information. When service of a dispatched elevator is terminated, a communication device (46, 50) communicates elevator reassignment instructions to passengers assigned to or located in the dispatched elevator.Type: GrantFiled: July 18, 2005Date of Patent: May 15, 2012Assignee: Otis Elevator CompanyInventors: Jannah Stanley, Paul A. Stranieri, Richard K Pulling, Jr., Vlad Zaharia, Daniel Williams, Richard Mangini, Wade Montague

Patent number: 7597176Abstract: A method for determining a position of a moving object, such as an elevator car in an elevator shaft, includes the steps of mounting a leading sensor and a lagging sensor to the moving object and spacing the leading sensor from the lagging sensor by an offset distance, mounting a plurality of spaced apart position indicators along a pathway of the moving object, transmitting signals representative of object position from the leading sensor and the lagging sensor to a controller as the sensors pass the spaced apart position indicators, and filling any gaps in the signal gathered from one of the sensors by using a correction factor established from the position sensed by the other sensor and the offset distance. A system for performing the method is described.Type: GrantFiled: August 10, 2004Date of Patent: October 6, 2009Assignee: Otis Elevator CompanyInventor: Vlad Zaharia

Patent number: 7559408Abstract: 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.Type: GrantFiled: May 19, 2004Date of Patent: July 14, 2009Assignee: Otis Elevator CompanyInventors: Michael P.

Patent number: 7353915Abstract: An elevator system (20) utilizes destination entry dispatching techniques. A controller (28) receives an automated destination request that includes a prestored, primary destination. This allows for seamlessly integrating building access and destination entry for the elevator system. A passenger interface (40) allows a passenger to override a prestored destination. The elevator controller (28) allows for override or secondary destination requests to be made at various intervals between receipt of the initial request and arrival of an initially assigned car at an appropriate level to let the passenger board the elevator car.Type: GrantFiled: September 27, 2004Date of Patent: April 8, 2008Assignee: Otis Elevator CompanyInventors: Vlad Zaharia, Wade Montague, Richard Mangini, Gary Meguerdichian, Richard K. Pulling, Jr., Paul Stranieri

Patent number: 7328775Abstract: An elevator system utilizes a destination entry control technique and delays indicating which car is assigned to a request to allow an individual to arrive near an elevator lobby. An elevator group assignment is made responsive to a destination request. An indication regarding the group assignment is provided to a passenger within a first time from the receipt of the request. A second indication regarding a car assigned to carry that passenger to the desired destination is provided at a second, later time from the request. Separating out the group assignment indication and the car assignment indication is accomplished in one example by providing separate interfaces at different locations within a building.Type: GrantFiled: September 27, 2004Date of Patent: February 12, 2008Assignee: Otis Elevator CompanyInventors: Vlad Zaharia, Theresa Christy, Richard Mangini, Jannah Stanley, Paul Stranieri, Wade Montague

Patent number: 6707374Abstract: Directionally sensitive motion detectors at the entrances to elevator cars provide a running count of passenger population aboard the cars. Passengers wear portable devices that transmit personal IDs, and a check of IDs of passengers on the elevator along with the total passenger count will determine if each of the passengers exiting the elevator corresponds to an ID authorized to enter a particular floor of the building, or determine if each of the passengers aboard the car corresponds to an ID authorized to make a particular trip (the particular elevator at a particular time). Unauthorized exit may cause an alarm or other events. If any passenger does not have an ID authorized for a secure trip, an announcement urges the unauthorized passenger to leave for some period of time, following which an alarm is sounded and the elevator is prevented from moving. Pairs of motion detectors may provide directional sensitivity, or doppler motion detectors may be used.Type: GrantFiled: July 21, 1999Date of Patent: March 16, 2004Assignee: Otis Elevator CompanyInventor: Vlad Zaharia

Patent number: 6483047Abstract: Load cells 35, 56 on antirotation dowel pins 28a or load mounts 49 indicate brake reaction forces in the disk brake 8, 8a of an elevator. Vertical load cells 72, 73 on bending load cell 80 indicate vertical brake reaction loads on a rail 60. A table indicating the load of an empty car at each of the landings served by the car permits subtracting load components relating to ropes, chains and cables to provide a live load indication prior to brake release; this may be used to determine if the load exceeds the maximum permissible load for the car.Type: GrantFiled: September 13, 2000Date of Patent: November 19, 2002Assignee: Otis Elevator CompanyInventors: Vlad Zaharia, Nigel B. Morris

Patent number: 6435315Abstract: Apparatus for determining the position of an elevator car within a hoistway that includes a code rail containing optically readable indicia that is being mounted within the hoistway adjacent to the path of travel of the car. At least one camera is mounted upon the car for movement therewith for scanning the code rail indicia and providing data indicative of the car's position to the car controllers.Type: GrantFiled: December 11, 2000Date of Patent: August 20, 2002Assignee: Otis Elevator CompanyInventor: Vlad Zaharia

Publication number: 20020104715Abstract: An elevator system includes an inspection device that provides information regarding a condition of the elevator rope or belt. The inspection device preferably is positioned to inspect an entire portion of the rope or belt that is most likely to wear as the elevator cab travels between chosen locations. In some situations, the inspection device is at a fixed position within an elevator hoistway. In other situations, the inspection device is supported for movement relative to other elevator system components. In one example, the inspection device is supported on the cab and moves with the cab through the hoistway. A variety of factors are considered for determining the portion of the rope or belt that is most likely to wear and the ideal placement of the inspection device relative to the other elevator system components.Type: ApplicationFiled: February 7, 2001Publication date: August 8, 2002Inventors: Vlad Zaharia, Pedro S.
