Abstract: A human-machine interface device can be arranged on a building. The device can include a communication device, a recording device, an optical projection module and a control device. The communication device sends and receives data signals via a communication network, and the recording device records data relating to a user. The control device is configured to transmit user data recorded by the recording device to a control system of a building system and to control the optical projection module based on routing information. The optical projection module is configured to project routing information relating to the user and visible to the user onto a projection surface.

Abstract: The invention relates to an elevator system that has a number of elevator operating devices which are arranged on floors of a building and which are connected to an elevator controller. At least one first elevator operating device is permanently assigned to a single destination floor such that inputting an elevator call on the first elevator operating device generates a destination call comprising data that specifies the floor on which the first elevator operating device is arranged as the boarding floor and the destination floor which is permanently assigned to the first elevator operating device as the destination floor.

Abstract: Premises access information can be distributed using a system having a ticket server coupled to a remotely located premises server. The ticket server receives a ticket request from a host device. After interacting with the premises server, the ticket server sends access-related information to a visitor device. The visitor device can later use the access-related information to gain access to a premises.

Abstract: A visitor can receive guidance (e.g., movement directions) through a portable electronic device. The visitor can read an information-containing tag with the electronic device to input location information into the device. With the electronic device, the visitor can then select one or more destinations. The device then provides directions to the visitor for the one or more destinations.

Abstract: The telephone (1) comprises a base (2) adapted to be connected to a telephone line, a first handset (4) connected to the base (2) by a flexible cord (5) and a second handset (6) connected to the base (2) by a radio link. To reduce the size of the base (2), the latter is formed with a cavity (11) in which the second handset (6) can be fully inserted, or at least substantially so. This cavity (11) communicates with the exterior of the base through an opening (11b) formed in one of the walls (2c) of the base's casing, such that the microphone and the earpiece of the second handset (6) are acoustically linked with the exterior of the base (2) and hence enable the second handset (6) to be used even when it is lodged in its cavity (11).

Abstract: The invention relates to telephones that have a base and two handsets or one handset and a base acting as a second handset and which are adapted to be connected to two or more telephone lines. Unlike known telephones designed to be connected to a set number of lines and to no other, the telephone according to the invention comprises an adapter that enables it to be connected equally well to a single line as to two lines or more, depending on the maximum number of lines for which it has been designed, and to provide in each case the same scope for communication between parties as a known telephone connected to the same number of lines. The adapter preferably includes change-over switches that can be operated by acting on a control device that is accessible from outside the telephone, but it may also include change-over switches or wire connections located inside the telephone.

Abstract: The telephone comprises a handset (8) having a receiver and a microphone, and a base (2) on which the handset may be placed. According to the invention, the casing (28) of the base is fitted with another receiver and another microphone and has a shape such that the base may be used as a second handset, thereby enabling two people to converse at the same time with one outside person if the phone is connected to one line or with different outside people if the phone is connected to two lines.
