Abstract: A transaction method, a service center, and a device for carrying out the transaction method. In the transaction method object picture data relating to a transaction object, for example a product or a service, are made visible to a user, for instance by projecting image signals corresponding to the object picture data directly on the retina of the user. Eye features of the user are determined while the object picture data, made visible, are viewed by him/her, for example by the light being captured that is reflected by the retina owing to the projected image signals and retina patterns of the user being determined from the determined reflection data and the associated object picture data. The determined eye features with object data relating to the transaction object are linked in a transaction record and the transaction record is forwarded to a processing unit.

Abstract: Method for anonymously transmitting a message by means of a telecommunication network. A first exchange (2) between the sender (1) and the receiver (4) of said message replaces identifying features (MSISDN) of the sender (1) of the message by a first alias identification (CID). The conversion between the said identifying features (MSISNDN) and the first alias identification (CID) is permanent, or at least secure for several weeks. The first alias identification (CID) is replaced by a second alias identification (CMID) at the receiver (4) or in a further exchange (3). The second alias identification (CMID) enables the receiver to identify the transmitter.

Abstract: Method with which a first user of a mobile telecommunications network, in which users are identified with a chip card by the provider of the telecommunications network, can provide objects to other users of the telecommunications network, with the following steps: reserving by the first user of a memory area in an accessible database in said telecommunications network, in which at least a number of users can store objects, for example documents and programs, filing by the first user of objects in said memory area, allocation by the first user of access authorizations for said objects, sending by a second user of a query to said database, verification of the access authorization of the second user through the database administration system, by using the second user's identity stored in his said personal identification module for his identification in the database administration system, if his access authorization allows it, sending of a reply from the database to the second user.

Abstract: A method, a mobile device and a central unit for supplying a mobile user with service information relating to real world objects viewed by him, picture data for at least one of the objects being captured and made visible to the user by a picture producing device worn or carried by the user in that picture signals corresponding to the picture data are projected directly on the retina of the user, the user selecting a picture segment from the made-visible picture data which is determined through eye positions of the user, picture segment data based on the picture segment being sent to a processing unit which is located in the mobile device or in the central unit and which determines the desired service information based on the picture segment data, for example a translation of the text information provided on the viewed objects or background information on the viewed objects, and this service information being reproduced for the user, for example in visible or audible form.

Abstract: Proposed is a transaction method between a customer and one of a plurality of service terminals (4) which supply selectable products and/or services, subject to costs, on location, as well as a sales system for carrying out the transaction method, whereby, by means of a portable mobile device (1) of the customer, an order record (6), comprising a service terminal identification (62) of the service terminal (4), is transmitted via a mobile radio network (2) to a service center (3), the service center (3) checking the credit worthiness of the customer from whom the order record was transmitted, and, in the case of positive credit worthiness, transmitting a credit record comprising a credit value via a communication network (2′) to the service terminal (4) identified through the service terminal identification (62), and whereby, on the basis of the received credit record, the service terminal (4) releases the selection of a product and/or of a service and supplies the desired product or the desired service

Abstract: Method and system for video conferencing with at least three different video conference participant stations, which communicate with one another by a telecommunications network. Multimedia data is transmitted over the telecommunications network including at least participant image data and/or participant audio data, and each participant receives the participant image data of the other participants shown at the same time visually arranged on a reproduction device. An eye tracking system registers the direction of view of the respective participant and transmits it to a communications unit. Those participant image data which are not shown in the momentary direction of view of the respective participant are transmitted over the telecommunications network to the communications unit with reduced resolution and/or video transmission rate.

Data can be received in the control unit from the modules by the radio device interface, or respectively transmitted selectively to the modules by the radio device interface, it being possible to configure from which signal receiving modules data is supposed to be conducted to which signal emitting modules.

Abstract: In a wireless local communication network, a so-called Wireless Local Area Network (WLAN) a prepaid value code is transmitted from a wireless communication terminal via an air interface to an access point unit of the wireless local communication network, a so-called access point. The validity of the received value code is checked in a value code database by a centralized access control server. If applicable, the access to the wireless local communication network and to communication networks connected thereto, for example the Internet, is cleared for the wireless communication terminal. After the clearance, a monetary amount is credited to the operator of the access point unit and the validated value code is cancelled in the value code database.
