摘要:
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.

A drainage arrangement for a tailgate of a motor vehicle body has water outflow spouts in the inner panel of the tailgate. The water outflow spouts are arranged correspondingly to water outflow openings in a rear part or a rear-end trim panel of the body behind a vehicle license plate as viewed in relation to the direction of travel.

摘要:
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.

A Class E switching-mode dc/dc power converter is obtained by adding a rectifier circuit at the output of a Class E dc/ac power inverter. It can operate at high efficiency at high switching frequencies. Further, the power switch is not subjected to high power dissipation or high second-breakdown stress while it is switching between the "on" and "off" states, even if the dc load on the power converter varies over a very wide range, e.g., from open-circuit to short-circuit. The high efficiency is achieved by shaping the waveforms of switch voltage and switch current so that the transitions of those two waveforms are displaced in time from each other. Then the power switch does not experience simultaneously high voltage and high current while switching. High efficiency and low stress on the switch are achieved under all load conditions by interposing a matching network between the output of the Class E dc/ac inverter and the input of the rectifier circuit. That matching network transforms the rectifier input impedance in such a way that the impedance presented to the output of the Class E dc/ac inverter is always in the range which generates switch voltage and current waveforms that yield low power dissipation and low second-breakdown stress during switching, for any value of dc load resistance at the output of the rectifier.

A motor vehicle with at least one air guide device, which can be extended by means of a drive device, and which can be adjusted to at least one intermediate position between a maximally extended and a completely retracted position. The motor vehicle comprises an adjustable sliding/tilting roof, wherein a control unit is provided, which is designed so that it acts on an air guide element of the air guide device as a function of the position of the sliding/tilting roof.

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 characterised by the best offset goodness values are stitched together and the two image blocks characterised 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.

A laminated panel of the type comprising a laminar core with a unitary covering of resin-impregnated fibrous material on each side, and having a raised scuff extending along one side of the panel is characterized by the fact that the scuff is molded in situ with the resin-impregnated fibrous material so as to form an integral part of the covering on that side of the panel. The scuff has bevelled edges which merge into the surface of the panel thereby eliminating corners and crevices thereat.

A method of annealing both N and P-type ion-implanted GaAs and InP semiconductors by using a close-contact capping technique. A flat polished ion-implanted surface on a gallium arsenide (GaAs) or indium phosphide (InP) semiconductor is placed in face-to-face contact with a non-reactive flat surface such as Si.sub.3 N.sub.4, SiO.sub.2, AlN, or identical semiconductor material, and annealed at selected elevated temperatures and time dependent upon ion concentration. The annealed semiconductor material, usually in the form of a wafer, is allowed to cool to room temperature for further processing.
