摘要:
A filtering apparatus for filtering a fluid includes a filter element for filtering the fluid and an adhesive capillary structure for generating capillary forces. The adhesive capillary structure is attached to the filter element by using an adhesive property of the adhesive capillary structure. The adhesive capillary structure is preferentially made of a double-sided tape, which is adhesive on two sides. The filtering apparatus further includes a filtering location where the filter element is located, and a detection location where a property of the fluid is detectable. The capillary structure is formed such that the filtered fluid is guided from the filtering location to the detection location.

The present invention provides a biosensor comprising a cartridge for accommodating a fluid sample, the cartridge comprising at least two chambers, wherein each chamber comprises a sensor surface with one or more binding sites. The biosensor further comprises means for generating a magnetic field at the binding sites of the sensor surfaces of the at least two chambers. The biosensor also comprises means for detecting particles accumulated at/and or proximate the binding sites of the sensor surfaces of the at least two chambers. Therein, the magnetic field at the binding sites has a sufficiently large gradient to actuate magnetic label particles towards the binding sites.

The present invention relates to a filtering apparatus (1) for filtering a fluid (3) comprising the filtering apparatus. The filtering apparatus comprises a filter element (2) for filtering the fluid (3) and an adhesive capillary structure (5) for generating capillary forces, wherein the adhesive capillary structure (5) is attached to the filter element (2) by using an adhesive property of the adhesive capillary structure (5). The adhesive capillary structure is preferentially made of a double-sided tape, which is adhesive on two sides. The filtering apparatus comprises further preferentially a filtering location (6), at which the filter element (2) is located, and a detection location (7), at which a property of the fluid (3) is detectable, wherein the capillary structure (5) is formed such that the filtered fluid is guided from the filtering location (6) to the detection location (7).

A method and device are disclosed for writing data marks representing a sequence of channel bit values to an optical disc or a master disc along either one or more concentric or spiral data tracks or along at least one concentric or spiral metatrack consisting of two or more parallel concentric or spiral sub-tracks. The method comprises the steps of—partitioning the sequence of channel bit values into an ordered set of two or more channel bit data files,—providing a periodic rotational motion and a radial motion of the disc and of at least one writing beam spot on the disc relative to each other so as to guide each writing beam spot along at least one data track or sub-track,—periodically providing an angular position signal derived from the rotational motion and indicative of the completion of one full turn of the rotational motion or a predetermined fraction thereof,—switching to a respective channel bit data file next in order with each angular position signal and writing a respective section of the sequence of channel bit values contained therein to the disc. According to the method of the invention, in the partitioning step the length of a respective section of the sequence of channel bit values to be contained by a respective channel bit data file is determined such that the complete respective section of the sequence of channel bit values contained by the channel bit data file is written to the disc between two consecutive angular position signals. The method provides an enhanced precision in the alignment of data marks, which is especially useful for synchronizing two-dimensional data patterns on a disc. Also disclosed are a method and a device for channel bit data file construction from a sequence of channel bit values, and a channel bit data memory.
摘要:
For determining the alignment of a substrate with respect to a mask, a substrate alignment mark, having a periodic structure, and an additional alignment mark, having a periodic structure and provided in a resist layer on top of the substrate, are used. Upon illumination of these two marks, having a period which is considerably smaller than that of a reference mark, an interference pattern is generated, which has a period corresponding to that of the reference mark. By measuring the movement of the interference pattern with respect to the refernce mark, the much smaller mutual movement of the fine alignment marks can be measured. In this way, the resolution and accuracy of a conventional alignment device can be increased considerably.
