Abstract: The aim of the invention is to produce complete high temperature fuel cells by means of thermal injection processes (e.g. atmospheric plasma injection, vacuum plasma injection, high speed flame injection). The production method is especially simplified and is economical by virtue of the fact that the carrier substrate is also produced on a base with the aid of a thermal injection method. The base or an intermediate layer placed thereon can be advantageously dissolved or decomposed such that the carrier substrate provided with layers arranged thereon can be separated in a very simple manner from the base which becomes unnecessary. Said method advantageously enables the production of all layers of a high temperature fuel cell, exclusively with the aid of a thermal injection method.

Each switching unit has a plurality of input/output interfaces, whereby at least one of the plurality of input/output interfaces of each switching unit of the first group forms an input/output port of the communications system, and at least one other input/output interface of each of the switching units of the first group is connected via a communication link with an input/output interface of one of the switching units of the second group, so that a network is formed having at least one loop. The network is logically divided in at least two virtual subnetworks, each forming a spanning tree. Each switching unit of the first group is configured to assign an incoming data packet arriving at a particular input/output port to a predetermined one of the at least two virtual sub-networks.

Abstract: The present invention relates to an imaging method and device for nuclear magnetic resonance. On the one hand, the method provides an image coding by means of an additional field which has, for each point of a two-dimensional grating surface within the sample, a different field strength value that occurs only once, as is the case, e.g., in fields based on fractal, surface-filling and space-filling curves. On the other hand, the read-out of the resonance behavior of a sample along a space-filling and/or surface-filling curve can be provided. In the first variant, a magnetic resonance (MR) image with a single high-frequency excitation without a time-varying gradient can be recorded, which in turn advantageously prevents the sound generation associated therewith. In the second variant, the sounds generated during read-out are advantageously shifted to another frequency range in which the human hearing is less sensitive.

Abstract: A digital image in CMOS camera images is processed by first generating an output signal g from a CMOS camera. Then its spatio-temporal gradient (gx, gy, gt) is derived from the output signal. A time constant c and a local object shift (ux, uy) are established from prior knowledge. Finally a target signal value q is calculated from the output signal g as q=(gx*ux)+(gy*uy)+(g*?1*c)+gt.

Abstract: An MR image imaging procedure for the acquisition of the longitudinal spin-lattice relaxation time has a data-acquisition module with a slice-selective ?-high-frequency impulse as well as magnetic gradients (Gx, Gy, Gz) for slice selection and/or for encoding of a k-space. The acquired data describes a time point of a spin-lattice relaxation and the data-acquisition module for acquiring data of a further time point being repeated. A 180° high-frequency impulse or a 180° high-frequency impulse and a 90° high-frequency impulse preceding the 180° high-frequency impulse generating a spin-lattice relaxation precede the data-acquisition module. The magnetic gradients Gx and Gy for k-space encoding are simultaneously applied subsequent to the slice-selective ?-high-frequency impulse. A temporal course of the magnetic gradients Gx and Gy is sinusoidal so that the result is a spiral coverage of the k-space and data are acquired during k-space encoding.

Abstract: The invention relates to a device for carrying out a tomographic method, in particular for carrying out single-photon tomography, with at least one multi-hole collimator and at least one detector, for recording photons which pass through the multi-hole collimator. The above is characterised in comprising means which permit a relative translational movement between an object under investigation and the detector(s) with a positional accuracy of less than 1 millimeter. The relative positional change between object and detector(s) during the execution of the method is taken into account in the subsequent reconstruction method to an accuracy of less than 1 mm, in particular, less than 0.1 mm. A reconstruction method is used for the above which takes into account the positional and angular information between object and detector. Said method may be controlled by and carried out on a current PC.

Abstract: An apparatus for hyperpolarizing atomic nuclei through optical pumping has a cylindrical optical pumping cell having an inlet and an outlet spaced therefrom. A supply of a mixture of optically pumpable species and hyperpolarizable nuclei is connected to the inlet of the cell. A nozzle at an inlet of the optical pumping cell forms and injects a jet flow of the mixture into the optical pumping cell. It is then drawn out through the outlet such that the mixture touches the inner walls of the optical pumping cell only adjacent the outlet.

Abstract: The invention relates to a method for increasing the efficiency of surfactants as well as to a method for suppressing lamellar mesophases in microemulsions. According to the invention, block copolymers having a water-soluble block A and a water-insoluble part B are admixed to the surfactants. The use of these substances as additives can considerably increase the efficiency of the surfactants. Moreover, the addition of the block copolymers suppresses the formation of undesired lamellar mesophases in microemulsions.

Abstract: Liquid fuel is evaporated and mixed with an oxidizing agent in a mixing chamber of a reformer by first introducing substantially only the liquid fuel in an axial downstream direction into a first upstream zone of the mixing chamber via a nozzle so as to atomize the liquid fuel. Then steam is separately introduced into the upstream zone and contacted with the atomized fuel to cause the fuel to evaporate. An oxidizing agent is then introduced downstream of the first zone in a second zone of the mixing chamber to the evaporated fuel and uniformly mixing the oxidizing agent with the evaporated fuel.

Abstract: The invention relates to a method for the topographical presentation of structural alterations in an examined brain using volume data records. In line with the invention, this method is distinguished in that functional areas are mapped by extracting profiles, where the profiles record boundaries for two functional areas in the examined brain, in that the boundaries of the two functional areas are recorded by calculating a multivariant distance measurement, and in that a microstructure in the region of the boundaries of the two cortical areas is recorded and is compared with at least one microstructure in a boundary region of a reference brain. To increase the comparability of various areas in various brains taking into account the interindividual variability, it is expedient for the volume data records to be transformed to a target volume data record using an elastic registration method.
