Abstract: An elevator system with an elevator group with a plurality of elevators and a group controller is configured to receive building information from a building management system. For each elevator, the received building information results in an assignment of each elevator to at least one elevator lobby for a specified floor, from which elevator lobby the assigned elevator can be accessed on the specified floor. Building information stored in a memory device of the elevator system is updated with the received building information, wherein, for each elevator, the stored building information indicates an existing assignment of the respective elevator to at least one elevator lobby for the specified floor. Upon receipt of an elevator call, the elevator system is operated according to the updated building information.

Abstract: Methods and systems to control access to a predetermined service or area. An access code is read from a portable electronic device of a user using an access terminal at a service site. As a result of reading the access code from the portable electronic device, access-related information is transmitted to the portable electronic device.

Abstract: An access control method can include sending an identification code to an access node using a mobile telephone. If the identification code is recognized as valid, an access code is sent from the access node to the mobile telephone and presented on the display of the mobile telephone. The access code is detected using a camera, and if the access code is recognized as valid, the access is granted.

Abstract: Elevator car position information can be determined based at least in part on readings from a sensor attached to the elevator car. The sensor readings provide movement information for the car. Some elevator installations are also configured with additional sensors for calibrating the sensor attached to the elevator car. The sensors can be used with, for example, an elevator installation that is being modernized.
