US Patent 7353915 Automatic destination entry system with override capability

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.
