Abstract: Disclosed is a method for integrating at least one optical element inside an insulated glazing unit comprising at least two glass panes, where the optical element has a plurality of perforations and a non-perforated area, where the non-perforated area prevents penetration of light in a building where the insulated glazing unit is mounted, and where the perforations have a depth/width ratio that allows for passage of light with given angles of incidence, while light having other angles of incidence are unable to pass though the perforations, which provides a shading effect, and wherein the optical element is arranged between the two glass panes by means of an adhesive, and where the adhesive is substantially not present in the perforations of the optical element.

Abstract: A method of producing a microfluidic device having at least one flow path may include providing a base substrate with a first surface and a top substrate with a second surface, hydrophilically treating at least one of the first and the second surfaces to provide a surface layer with a higher surface tension than the surface tension prior to the hydrophilic treatment, partly or totally removing the surface layer with a higher surface tension in a selected pattern of the hydrophilically treated first and/or second surfaces, to thereby provide the selected pattern with a lower surface tension than prior to the partly or totally removal of the surface layer with a higher surface tension in said selected pattern of the hydrophilic treated first and/or second surfaces, and joining said base substrate and top substrate to each other to provide a flow path between said first and second surfaces.

Abstract: A method and flow system for controlling the flow of a liquid in a flow system, the liquid flow comprising particles and being led into a channel thereof. The method comprises the steps of enveloping the liquid flow by a flow of carrier liquid, hydrodynamically focussing the particles in the liquid flow providing a measurement signal of the liquid flow from an observation area in the channel, and dividing the liquid flow at a branching point into two or more outlets in response to the measurement signal. The division of the liquid comprises introducing a control liquid from at least one control channel at a merging point or merging area in the channel. The amount of control liquid is controlled by at least one electro-kinetic pump, the pump effect of which is controlled in response to the measurement signal.

Abstract: With a method of controlling the flow in a flow system where a liquid flow contains a particle concentration, the liquid flow is surrounded by a carrier liquid. The liquid flow and carrier liquid are led into a central channel in which there is provided an observation area (4) where measurements of the liquid flow are effected. The result of the measurements are used to lead the liquid flow into one of several channels, in that control liquids are introduced into the liquid flow before this reaches the channels, the control liquids being derived from a capillary pump structure which pumps on the basis of an electro-kinetic effect, e.g. an electro-osmotic effect. In a preferred embodiment, the pump structure consists of two capillary structures, to each of which an electrical field can be applied. Depending on the strength of the field, the amount of control liquid will be able to be controlled so that the liquid flow with the particle concentration can be led to one of two channels.
