The object of the invention relates to an objective changing and focussing apparatus () for microscopes () containing a plurality of objectives (), and having an optical axis Z, the essence of which is that it contains&#x2014;a first rail system () having a first guide rail () fixed to the microscope () and a first moving member () guided by the first guide rail (), wherein the first rail system () is arranged along an axis X perpendicular to the optical axis Z, &#x2014;a first drive unit () in drive connection with the first rail system (), &#x2014;a plurality of objective interface elements (), adapted for being connected to the objectives (), arranged next to one another along the X axis and fixed to the first moving member () movably along the Z axis, &#x2014;a second rail system () having a second guide rail () fixed to the microscope () and a second moving member () guided by the second guide rail (), wherein the second rail system () is arranged parallel to the optical axis Z, and defines a starting position along the X axis, and&#x2014;a second drive unit () having a second drive connection with the second rail system (), and the second moving member () is provided with a lifting element () providing a releasable connection with an objective interface () located in the starting position. The object of the invention also relates to a microscope containing such an objective changing and focusing apparatus ().

A microscope stage is movably mounted to a base and is movable relative to the base by two separate drive units on separate rail systems situated at an angle relative to one another. The drive units are mechanically isolated from one another and one of the drive units uses a belt drive.

A method for realistic stitching and showing image blocks of an electronically recorded multipart image wherein relative positional offset values of the image blocks recorded with overlap are determined in a co-ordinate system in directions x and y and stored in matrix format, and the image blocks to be presented are stitched together on the basis of the stored values the method comprising: subdividing the overlaps of the individual image blocks into smaller regions with fixed relative positions; picking up at least one region most useful for the determination of the stitching; determining the offset goodness value based on the similarity of pattern of the image blocks; stitching the blocks of the image so that first the two image blocks characterized by the best offset goodness values are stitched together and the two image blocks characterized by the worst offset goodness values are stitched together last, whereas only the co-ordinates of the images figuring in a table are modified in the course of the stitching process; and distributing the errors produced by the stitching process over several image blocks.

Automated, microscope-assisted examination process of tissue or bodily fluid samples

A method for the analysis of a component of a medical sample with the aid of an autoanalyzer, in which the sample is reacted with a reagent system and a physically measurable quantity X resulting from the reaction of the sample with the reagent system is measured in order to determine at least one measured value R for a specified sample and in which this at least one measured value R is further processed with the aid of a processing unit in a processing stage in order to determine an analytical result A. In the processing stage of the invention, use is made of the results of a neural net training, in which, for a number of standard samples for which the analytical result A is known, at least one measured value R, or a measurement result derived from several measured values R.sub.i, is applied to the input of a neural net.

The invention relates to novel nitrogen- and sulfur-containing heterocyclic compounds of the formula (I), acid addition salts thereof, pharmaceutical compositions containing them and a process for their preparation. In the formula (I) ##STR1## Ar stands for an optionally mono- or polysubstituted aryl or heteroaryl group;

Heterocyclic compounds containing nitrogen and sulfur, pharmaceutical

A multi-stage switching-field formed with switching matrices containing thyristors for stored program controlled switching devices, established by reversal at the last stage, without the use of transformers or other reactive elements therein (e.g. capacitance), in the last stage a holding circuit remains invariable upon switching on, furthermore allocating and switching circuits are ordered to the coupling paths instead of the stages. Circuit arrangements of the switching-field provide the possibility for attenuation control too, and do not require voltages of opposite polarity, while at the same time provide an interface requiring uniform, short operations towards the stored program control device. The switching matrices are switched on at minimal power-level, thus the switching of each further coupling path or connection does not increase the noise level of the already existing connections. The switching-field provides effective protection against unwarranted disconnections caused by noise arriving from the lines, and ensures through impedance matching to attain the optimal ratios of the insertion loss, dynamic range of the connections, and cross-talk attenuation between the different connections. The circuits developed for the switching-field according to the invention are suitable also for production with hydrid or monolithic technology.
