A method for controlling access to a resource of an application in a data-processing device, comprising the steps: registering an access interface of an access-management component at the data-processing device; request by a first application for an access to the access interface of the access-management component at the data-processing device; registering of a resource of the first application at the access-management component actuation of a second application by a user which requests access to the resource of the first application; sending an access-authorization query of the first application about the user to the access-management component; and, given authorization of the user, granting access to the resource of the first application by the second application.

A method and a device, respectively, for controlling a barricade of a parking space for a vehicle are proposed, the method being used to change a code as needed with which authorization for controlling the barricade of the parking space is attained and to recognize a plurality of codes as authorized for one barricade. A code is able to be changed using a password. The radio signals are preferably transmitted via Bluetooth. A dwell time of the vehicle in the parking space may also be logged. A code may be designed as a personal identification number or as an identification number of the vehicle or of the radio module. The barricade is designed as either a garage door or a barrier.

A method for the transmission of data using radio transmission systems between transmitter/receiver stations is provided, and a computer for the allocation of radio transmission systems for the transmission of data between transmitter/receiver stations is provided, which serve to select radio transmission systems dynamically, for a communication from at least one transmitter/receiver station, on the basis of a subscriber profile, a location of the one transmitter/receiver station, and/or a speed of the transmitter/receiver station, in order to transmit data between transmitter/receiver stations. A computer in a switching device calculates which radio transmission system best meets the criteria. During a data transmission, it is possible to switch automatically to a further radio transmission system if the transmission quality of the radio transmission system currently being used declines.

METHOD FOR TRANSMITTING DATA BETWEEN MASTER/SLAVE STATIONS BY MEANS OF RADIO TRANSMISSION SYSTEM AND COMPUTER FOR THE ALLOCATION OF RADIO TRANSMISSION SYSTEMS FOR THE TRANSMISSION DATA BETWEEN MASTER/SLAVE STATIONS

The process for data transmission between two stations by means of data blocks each having a synchronization pattern field (SYNC), a header field (HEADER) and an information field (INFORMATION) following the header field includes providing a header control field (HEX) following the header field (HEADER) in each of the data blocks for reconstruction of the header field when a transmission of the header field contains errors.

Reliability information obtained during the channel decoding of the transmitted signal is averaged over the short term; the short-term average reliability information is mapped to detect residual errors. The variable obtained by the mapping step is compared with at least one decision threshold, and the result of the comparison is transmitted as residual error information. In addition, the reliability information can also be averaged over the long term, the variable obtained by the mapping step being modified by the long-term average reliability information.

Method for obtaining information on the residual errors in a transmitted

In a method for optimizing the transmission of signals, especially video signals, over a channel with a predetermined channel data rate after source encoding for data reduction and channel encoding, in which redundancy is added to the source-encoded signals for error control protection, at least one quality parameter of the transmitted and decoded signals is measured. As a function of the measured quality parameter, the relationship between the source accuracy of the source encoding and the added redundancy is changed in opposite directions to optimize the transmission.

A method for arithmetic decoding improves the reliability of the arithmetic coding. For the purpose of channel decoding, use is made of a soft output Viterbi algorithm which, along-side the decided data item, supplies an item of reliability information. In addition, a data item is predicted for the decided data item in accordance with channel-decoded and arithmetically decoded data already transmitted, and subsequently arithmetically coded and compared with the channel-decoded data item. If the two data items do not correspond, the distribution density function used for the arithmetic decoding is changed by using the reliability information, and the channel-decoded data item is subsequently arithmetically decoded using the new distribution density function.
