Abstract: In order to guide a person along a path, audible acoustic signals are used, which are generated by signal generators arranged in an area. The person can orient themselves in the area using these acoustic signals. As the person moves along the path towards a destination, the signal generator arranged next in line on the path generates an acoustic signal, in which direction the person can then move. A signal generator generates an acoustic signal of this type, when it receives a control command from a mobile device carried with the person or from a control device.

Abstract: An access control system is configured to detect the presence of a portable electronic device carried by a user in a first area. The access control system sends an access code to the device. In a second area, the user presents the portable electronic device to an access terminal, which reads the access code from the device. If the access code read from the device matches the access code that was sent to the device by the system, then the access control system grants access to the user.

Abstract: During an evacuation situation in a building that is equipped with an elevator system and in which a plurality of fixed point markers are arranged at defined sites, an escape route is transmitted to a person by means of a mobile device. The fixed point markers store data that can be received by the mobile device. An instantaneous position of the mobile device can be determined when the mobile device uses data received from a fixed point marker to access a database in which the data is linked to a site of the fixed point marker. The ascertainment of the escape route to a destination is based on the instantaneous position of the mobile device. The person is registered on reaching the destination when the mobile device is detected at the destination.

Abstract: A device serves for determining the speed of a passenger-transporting system. The device includes an arrangement of auxiliary elements and a sensing device. The arrangement of the auxiliary elements rotates, in a manner corresponding to a movement of the passenger-transporting system. The sensing device can sense whether an auxiliary element is, or is not, located at a certain sensing location. The auxiliary elements are of a first configuration type and a second configuration type. The sensing device can sense whether an auxiliary element is of the first configuration type or of the second configuration type. Furthermore, the sensing device can assign an auxiliary element of the first configuration type and an auxiliary element of the second configuration type to one another such that the direction of rotation can be determined from the order in which the auxiliary elements are sensed.
