US Patent:

7434665, Oct 14, 2008
Filed:

Jul 21, 2003
Appl. No.:

10/555531
Inventors:

Zuhair S. Bahjat - Farmington CT, US
Theresa M. Christy - West Hartford CT, US
Assignee:

Otis Elevator Company - Farmington CT
International Classification:

B66B 1/20
US Classification:

187383, 187247
Abstract:

In down peak, floors of the building are divided into sectors (), empty cars () are assigned () to the sector and assigned () the highest down call in the sector provided the highest down call is above the committable floor of any car already assigned in the sector, or there is no car assigned in the sector. If a car is not full (), it will be assigned additional calls (). If there are no calls in the sector below a car sector which is not full, a long calls routine () determines if there is a down call (), that is in danger of becoming a long-waiting call, ahead of a car () and if so, assigns that call to the car ().

Filed:

Jan 29, 2004
Appl. No.:

10/582049
Inventors:

Zuhair S. Bahjat - Farmington CT, US

The system provides a color indication (A-E) associated with an elevator car (A-E) that will travel to a passenger's intended destination floor. In one example, the portable device () provides a color indication that corresponds to the color indication (A-E) associated with the car. Providing the color indication () on the portable device () assists a passenger () in locating the correct car and provides piece of mind to the passenger that they are entering the correct car and will be carried to their intended destination floor.

Variable Elevator Door Dwell Time Based Upon Time Of Notification Of Assigned Car

US Patent:

52869300, Feb 15, 1994
Filed:

Jul 2, 1992
Appl. No.:

7/907727
Inventors:

Joseph Bittar - Avon CT
Zuhair S. Bahjat - Farmington CT
Assignee:

Otis Elevator Company - Farmington CT
International Classification:

B66B 1314
US Classification:

187103
Abstract:

Elevator door dwell time is varied as a function of arrival time so that a show-and-go time is met. The show-and-go time is the time from when the passengers are shown which elevator to board to the time when the elevator door is ready to close after the pasengers have entered the elevator. The arrival time is a function of the distance of the elevator from the floor of the hall call signal and is the time remaining after an elevator reaches a stop control point where a hall call assignment is fixed to a car until the door of said elevator begins to open. Door opening time, door dwell time, and arrival time are subtracted from a show-and-go time. If the difference is greater than or equal to zero, the door dwell time is increased by the difference, but if the difference is less than zero the door dwell time is decreased by the difference, and the doors are then held open at a landing for the door dwell time.

Elevator System Having Improved Crowd Service Based On Empty Car Assignment

US Patent:

53450493, Sep 6, 1994
Filed:

Oct 8, 1993
Appl. No.:

8/134517
Inventors:

Zuhair S. Bahjat - Farmington CT
V. Sarma Pullela - North Granby CT
Assignee:

Otis Elevator Company - Farmington CT
International Classification:

B66B 118
B66B 120
US Classification:

187127
Abstract:

A method for controlling the dispatching of elevator cars, and apparatus for accomplishing the method. The method includes the steps of (a) receiving a hall call from a floor landing; (b) determining a current passenger load of an elevator car; (c) determining if a crowd signal is generated for the floor landing; and, if it is determined that a crowd signal is generated for the floor landing, (d) determining, from the current passenger load, if the elevator car is EMPTY. If it is determined that the elevator car is EMPTY, the method further includes the steps of (e) assigning an Empty Car Bonus to the elevator car; and (f) employing the Empty Car Bonus value in determining a Relative System Response for the elevator car. The Relative System Response is a function of a plurality of bonuses and penalties. The use of the invention increases the efficiency of the elevator system and serves to decrease the waiting time for persons waiting behind the hall call by increasing the probability of an empty car being assigned to a hall call having a crowd waiting behind the hall call.
