Abstract: A method, a software application, and a reader for evaluating a matrix code in an image, in which the patterns of the individual symbol rows are reconstructed, and scanning values are determined at the intersections of the symbol row patterns. Firstly, the approximate position of each of the symbols along the symbol rows in the direction of a first dimension of the image is determined successively, with the determined pixel positions being used as the position of the symbols in the direction of the first dimension, and subsequently the patterns of the individual symbol rows along the other dimension of the complete image are determined successively. These two steps are then repeated for the other dimension. The scanning points are determined on the basis of the properties of the data modulation taking into consideration the channel distortions. A decorrelation of the scanned symbols reduceS the local inter-symbol interferences.

Abstract: A method processes a stable emulsion having components from whole-cell biotransformations such as cells, soluble cell components, organic solvents and/or water. In this connection, the emulsion, which is stable after the biotransformation, is mixed with further parts of organic phase, and subsequently the mixture is continuously stirred until a catastrophic phase inversion of the emulsion takes place while mixing; subsequently, this phase-inverted mixture is transferred to a settling container, where the phases of the emulsion separate from one another and can be separated from one another.

Abstract: A method for monitoring an airspace includes a first control and detection system and a second control and detection system. The first control and detection system has a first flying device and a first control and detection unit, and the second control and detection system has a second flying device and a second control and detection unit. An airspace monitoring system is different from the first control and detection unit and also from the second control and detection unit. First data relating to the first flying device is transmitted from the first control and detection unit to the airspace monitoring system, and data based on the first data is transmitted from the airspace monitoring system to the second control and detection unit. In this manner, the method allows a system-independent airspace monitoring process.

Abstract: A method for transmitting optical information between an emitter station and a receiving station via a multi-mode optical wave guide uses a wave length multiplex method. Several optical emitters generate a respective signal for each wave length to be transmitted. The signals are fed to the multi-mode optical wave guide in the form of a number of modes via mode multiplexers and wavelength multiplexers, the multi-mode optical wave guide having its own mode that can propagate within the multi-mode optical wave guide for each mode to be transmitted. After transmission and optionally regeneration and/or amplification of the signal via the multi-mode optical wave guide, the transmitted signals are broken down via the wavelength multiplexer into groups of signals having the same wavelength and via the mode demultiplexer into signals having the same mode. Subsequently, the interference signals are extracted from the transmitted demultiplexed signals.
