An elevator dispatching system includes a plurality of elevator groups, each of the plurality of elevator groups including a group controller and a plurality of elevator cars, each of the plurality of elevator groups serving a respective set of floors; and a redirector configured to receive a service request including a destination floor, and, in the event more than one elevator group serves the destination floor, communicate the service request to the group controllers of the more than one elevator groups, wherein the respective group controllers of the more than one elevator groups are configured to each determine a respective group score, and communicate the respective group score to the redirector, and the redirector is further configured to determine the best group based on the respective group scores.

An elevator dispatching system includes a plurality of elevator groups, each of the plurality of elevator groups including a group controller and a plurality of elevator cars, each of the plurality of elevator groups serving a respective set of floors; and a redirector configured to receive a service request including a destination floor, and, in the event more than one elevator group serves the destination floor, determine a best group to service the request from the plurality of elevator groups based on information stored in the redirector, wherein the group controller of the determined best group is configured to determine a best car from the plurality of elevator cars in the determined best group.

An exemplary elevator system includes a first controller configured to recognize a hall call signal that indicates a passenger's desire to board an elevator car at a particular landing. The first controller is associated with at least one elevator car for assigning a hall call request to that elevator car. A second controller is configured to recognize a destination request that indicates a passenger's desire to be carried to a particular level. The destination request originates outside of an elevator car. The second controller is associated with at least one elevator car for assigning a destination request to that elevator car. The second controller is configured to determine whether a selected condition will be satisfied if a received destination request is serviced by an elevator car associated with the second controller. The second controller handles the received destination request in that manner if the condition will be satisfied. A cross dispatcher is configured to communicate with the second controller and to handle the destination request. If the condition will not be satisfied, the cross dispatcher provides an indication of a hall call signal corresponding to the received destination request to the first controller.

Method of handling passenger requests during elevator modernization

An exemplary method of assigning calls to elevator cars includes ensuring that a passenger separation requirement is satisfied. The passenger separation requirement is satisfied when a passenger belonging to one service group is not carried in the same elevator car simultaneously with another passenger belonging to a different service group, for example. A call is assigned to an elevator car to carry a passenger belonging to the one service group while the elevator car is assigned to carry or is already carrying another passenger belonging to the different service group.

A destination entry input device () is commissioned in a group elevator system (). The destination entry input device () is connected to a dispatch controller (). A network address is input into the destination entry input device () corresponding to an installation location of the destination entry input device (). When the network address is input, installation location information related to the installation location of the destination entry input device is downloaded to the destination entry input device () and verified.

Elevator reassignment information is communicated to passengers in a group elevator system (). The group elevator system () includes a group of elevators (, 14, 14) that is operable to transport each of the passengers to one of a plurality of floors (L, F, F, F, F). A destination entry input device () at each floor permits each passenger to enter destination input information. A dispatch controller () assigns an elevator to each passenger based on the destination input information. When service of a dispatched elevator is terminated, a communication device () communicates elevator reassignment instructions to passengers assigned to or located in the dispatched elevator.

Communication of elevator reassignment information in a group elevator system

An elevator system () utilizes destination entry dispatching techniques. A controller () 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 () allows a passenger to override a prestored destination. The elevator controller () 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.

Automatic destination entry system with override capability

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.

A circuit breaker assembly including first and second circuit breakers each having toggle switch assemblies movable between ON and OFF positions. The toggle switch assemblies have connectors coupled thereto for preventing both circuit breakers from being in the ON position at the same time.

A saddle assembly (10) for a circuit breaker comprising a saddle base (22), at least one stab terminal (14) and two resilient tabs (50, 52) in facing alignment for releasably securing the at least one stab terminal (14) to the saddle base (22), wherein the engagement of the two resilient tabs (50, 52) with the stab terminal (14) releasably secures the at least one stab terminal (14) to the saddle base (22).

Saddle assembly for a circuit breaker

A lock-down device for use in a circuit breaker assembly. The device comprises a base for releasably securing the device to the assembly's saddle, an arm portion connected to the base, and a hand portion, connected to the arm portion, for engaging the housing of a first circuit breaker such that when the first circuit breaker and a second circuit breaker is mounted on the saddle the hand portion is intermediate the first and second circuit breakers and the first circuit breaker cannot be inadvertently removed from the saddle. In an alternative embodiment, the hand portion of the device comprises flanges for engaging and permitting the lock-down of the second circuit breaker as well.

A magnetic flux concentrator trip unit for molded case circuit breakers in the form of a flux concentrator magnet arranged round the load strap at one end of the circuit breaker is positioned in magnetic proximity to an armature. Current transport through the load strap generates attractive magnetic forces to articulate the circuit breaker operating mechanism when the current exceeds a threshold value.
