摘要： An improved method of imprint lithography involves using field-induced pressure from electric or magnetic fields to press a mold onto a substrate having a moldable surface. In essence, the method comprises the steps of providing a substrate having a moldable surface, providing a mold having a molding surface and pressing the molding surface and the moldable surface together by field-induced pressure from electric or magnetic fields to imprint the molding surface onto the moldable surface. The molding surface advantageously comprises a plurality of projecting features of nanoscale extent or separation, but the molding surface can also be a smooth planar surface, as for planarization. The improved method can be practiced without mechanical presses and without sealing the region between the mold and the substrate.

摘要： Automated detection of structure is provided in ultrasound M-mode imaging. A coarse and fine search for structure is used. For example, a less noise susceptible initial position or range of positions for a given structure is determined. This position is then refined. The coarse positioning and/or the refined position may use machine-trained classifiers. The positions of other structure may be used in either coarse or fine positioning, such as using a Markov Random Field. The structure or structures may be identified in the M-mode image without user input of a location in the M-mode image or along the line.

摘要： A method for determining the recirculation in a fistula and/or the cardiopulmonary recirculation part during an extracorporeal blood treatment is disclosed, where the blood to be treated flows in an extracorporeal blood circuit through a blood chamber of a dialyzer split by a semi-permeable membrane into the blood chamber and a liquid chamber, and dialysis liquid flows in a dialysis liquid path through the dialysis liquid chamber of the dialyzer. A device for determining the recirculation in a fistula and/or the cardio-pulmonary recirculation part, and a blood treatment device including such a device are also disclosed. The method and device are based on the fact that the sum of the fistula recirculation and the cardiopulmonary recirculation part, i.e. the total recirculation, is determined for two blood flow rates which differ from each other. The fistula recirculation and/or the cardiopulmonary recirculation part are then determined from the recirculation for the two blood flow rates.

摘要： Flexible, low-cost, physically robust optical coupling patches for use in spectrophotometric patient monitoring, and methods of fabrication thereof, are described. The optical coupling patch comprises a flexible base layer having a skin-contacting surface and a first aperture formed therethrough that establishes an optical interface with a skin surface when the base layer is placed against the skin surface. The optical coupling patch further comprises an elastomeric waveguiding member laterally disposed on a surface of the base layer opposite the skin-contacting surface. The optical coupling patch guides optical radiation between a laterally propagating state at a first location laterally distal from the first aperture and a generally vertically propagating state at the first aperture.

摘要： The invention relates to a method for monitoring the supply of substitution liquid during an extracorporeal blood treatment and to an extracorporeal blood treatment unit equipped with a device for monitoring the supply of substitution liquid. The monitoring of the supply of substitution liquid is based on the measurement of pressure waves, which are generated by the substitution liquid pump, in the extracorporeal blood circulation system. A disturbance in the supply of substitution liquid is inferred when the amplitude of the pressure waves exceeds a predetermined limit value. The amplitude of the pressure waves is preferably monitored in the venous blood line.

摘要： In accordance with the invention, step-and-repeat imprint lithography is effected by applying balanced pressing forces from both sides of a substrate. The pressing forces are substantially equal in amplitude and opposite in direction. With the pressing forces thus balanced, the fixture that steps and holds the substrate does not bear the load of imprinting. The balance allows use of a high resolution aligning stage to carry the substrate and to maintain high accuracy of positioning without being shifted by change of load. With this method, sufficient imprint pressure can be used to obtain high quality patterning, a thin and uniform residual layer, and a high fidelity pattern.
