Patent DE-19913585-A1 (DE)
Inventor: SCHWEIDLER SIEGFRIED
IPC: H04L12/28
Filed: 1999-03-25
Abstract: The format of the transmission of isochronous data packets via the IEEE 1394 bus is defined in the IEC 61883 Standard. In this case, it is possible to use an operating mode in which the same number of data blocks (DB0-DB7) is always transmitted in a bus packet. In this case, the memory management is extremely simple and the data source packet boundaries can easily be determined. However, the IEC 61883 standard also leaves open the possibility of transmitting a variable number of data blocks (DB0-DB7) in the context of isochronous data transmission with the aid of bus packets. In this case, however, subsequently ascertaining the data source packet boundaries poses a problem. The invention specifies a solution, favourable in terms of outlay, as to how the data source packet boundaries can easily be reconstructed. It is based essentially on modulo-n counting of data blocks (DB0-DB7).

An Independent claim is included for corresponding equipment to carry out the process. Preferred features: The evaluation unit determines double refraction , intensity, orientation and dichroism. The sample is preferably completely transparent, or translucent. Sample concentration is adjusted by applied pressure. The laser is pulse-modulated. It is fired in rapid succession, or the wavelength (color) is varied correspondingly. The modulation employed, is used in synchronizing measurements. The laser light is pulsed at a frequency between 10<2> Hz and 10<10> Hz. Photodiode detectors (7) are employed. Laser polarizations are at differing angles; the lasers are laser diodes. Detected values are translated into mean values, by the evaluation unit. Evaluation is made from a succession of modulation states. A set of equations provided, is used to make the determinations cited above, with inputs of laser intensity, wavelength, and optical element orientations. A feature noted in the apparatus, is the semi-silvered mirror located at the intersection of the laser beams.
