Abstract: A system and method for transmitting data between at least two communication terminals includes handling useful address data by a switching unit and handling useful data records by a data exchange node. A spatial distance of the at least two communication terminals is calculated. A time interval of communication inquiries to the switching unit in order to initiate a data transmission between the at least two communication terminals is determined. The data transmission is controlled depending on predeterminable threshold values of the spatial distance of the at least two communication terminals and the at least one time interval between the communication inquiries.

Abstract: A system for transferring information for at least one person in the area of an airport, comprising a) at least one personal end device which can be worn by the at least one person, b) a detection means for detecting the current spatial position of the at least one person in the area of the airport, c) a control means for determining at least one target time for a station located along the path to a flight gate assigned to the at least one person and/or for determining a path of the at least one person from a pre-determined position to the flight gate assigned to the person.

Abstract: The invention relates to a system for transmitting data between at least two communication terminals (10, 20), comprising a) at least one first communication terminal (10) and a second communication terminal (20), wherein at least one communication terminal (10, 20) is designed as a mobile device, in particular a hand-held device, b) a switching unit (30) that can be coupled to all communication terminals (10, 20) by way of a data network (100), characterized by c) a means (40) for calculating and/or evaluating the spatial distance of the communication terminals (10, 20), d) a means (50) for determining and/or evaluating time intervals of communication inquiries (200, 201, 202, 203) to the switching unit (30) in order to initiate data transmission between the at least two communication terminals (10, 20), e) wherein a connecting means (60) associated with the switching unit (30) controls the data transmission, depending on predeterminable threshold values of the spatial distance of the at least two communicat

Abstract: A method and device for the pictorial representation of space-related data, for example, geographical data of the earth. Such methods are used for visualising topographical or meteorological data in the form of weather maps or weather forecast films. Further fields of application are found in tourism, in traffic control, in navigation aids and also in studio technology. The space-related data, for example topography, actual cloud distribution, configurations of roads, rivers or frontiers, satellite images, actual temperatures, historical views, CAD-models, actual camera shots, are called up, stored or generated in a spatially distributed fashion. For a screen representation of a view of the object according to a field of view of a virtual observer, the required data are called up and shown only in the resolution required for each individual section of the image.
