Abstract: The invention relates to a cartridge (10) for processing of a liquid sample, for example for the detection of components in a sample of blood. The cartridge comprises a fluidic system with an intake port (12) leading via an intake capillary channel (13) to a storage chamber (14). Moreover, a feeding capillary channel (15) leads from the storage chamber (14) to a detection chamber (16). The design of the cartridge (10) is such that the intake capillary channel (13) that connects the intake port (12) to the storage chamber (14), has a capillary suction pressure sufficiently high to drive some sample from the intake port to the storage chamber without need of any additional pressure. Furthermore the cartridge a flow control element (18, 20) adapted to be externally controllable such that the sample can be drawn from the storage chamber (14) towards the processing chamber (16) without any active pumping.

Abstract: An embodiment of the invention relates to a fluidic system (200) in which a first channel (210) and a second channel (230) are separated by a fluidic stop (220), for example a region with a hydrophobic coating and/or a structure (220) with non-capillary internal dimensions. Moreover, it comprises a flexible element (240) that is deformable to enable a flow of a medium across the fluidic stop.

Abstract: The invention relates to microfluidic systems, and more specifically to a microfluidic system comprising a capillary channel (14) and an inlet (12) for receiving a fluid, as well as a method of filling a capillary channel (14). Provided is a microfluidic system, having an inlet (12) for receiving a fluid, a capillary channel (14), an outlet (20) for letting excess fluid out, and a reservoir (10) for interfacing the inlet (12) to the capillary channel (14). The reservoir (10) forms a first passage from the inlet (12) to the outlet (20), and a second passage from the inlet (12) to an entrance (22) of the capillary channel (14). A hydraulic resistance of the first passage is sufficiently low in order to effect a pressure reduction at the entrance (22) of the capillary channel (14) when a fluid is received under pressure at the inlet (12).

Abstract: The display device is furnished with a channel plate (39) comprising channels (30, 30', 30") containing an ionizable gas (33), and the walls of the channels (30, 30', 30") being provided with electrodes (31, 32) for selectively generating a plasma discharge of the ionizable gas (33) during operation. The display device further comprises an electro-optical layer (35) of a material having an optical property which is governed by the discharge state of the plasma discharge. The display device is characterized in that at least one of the electrodes (31, 32) is furnished with a layer (37) comprising particles of a sputter-resistant material having an average diameter .ltoreq.2.5 .mu.m, preferably .ltoreq.1.5 .mu.m. The particles are preferably composed of rare-earth borides (for example LaB.sub.6) or ruthenium oxide.

Abstract: A thin-panel picture display device having a luminescent screen is provided and by means of an addressing system, electrons are directed towards desired locations on the luminescent screen. A spacer plate of electrically insulating material, with apertures for passing electrons, is present between the addressing system and the screen. To provide the possibility of applying voltage differences of at least 5 kV across the thickness of the spacer plate, at least the walls of the apertures are coated with a coating of particles of nitrides, borides, carbides, oxides of chromium, yttrium, tantalum, with a secondary emission coefficient of .delta..sub.max .ltoreq.3.5 and an electrical sheet resistance of at least 10.sup.12 .OMEGA./.quadrature..

Abstract: Method of manufacturing an electrically conductive pattern of tin-doped indium oxide (ITO) on a substrate.Tin-doped indium oxide (ITO) can be selectively etched relative to the metals Mo, W and TiW in an etching bath which is obtained by diluting concentrated halogen acid, for example hydrochloric acid, with a liquid having a lower dielectric constant than water, such as acetic acid or methanol. This is particularly advantageous in the manufacture of the MIM switching elements which are present on the active plate of LCDs.
