Plasma source and surface treatment method. A plasma source has an outer surface (12), interrupted by an aperture (14) for delivering an atmospheric plasma from the outer surface. A transport mechanism (11) transports a substrate (10) in parallel with the outer surface, closely to the outer surface, so that gas from the atmospheric plasma may form a gas bearing between the outer surface the and the substrate. A first electrode (16a,b) of the plasma source has a first and second surface extending from an edge of the first electrode that runs along the aperture. The first surface defines the outer surface on a first side of the aperture. The distance between the first and second surface increasing with distance from the edge. A second electrode (17) covered at least partly by a dielectric layer (18) is provided with the dielectric layer facing the second surface of the first electrode, substantially in parallel with the second surface of the first electrode, leaving a plasma initiation space on said first side of the aperture, between the surface of the dielectric layer and the second surface of the first electrode. A gas inlet (19a,b) feeds into the plasma initiation space to provide gas flow from the gas inlet to the aperture through the plasma initiation space. Atmospheric plasma initiated in the plasma initiation space flows to the aperture, from which it leaves to react with the surface of the substrate.


The invention is directed at a method of manufacturing a stacked organic light emitting diode - OLED - device. The method comprises the steps of providing a carrier (9) and forming a first organic light emitting diode (9) on the carrier by means of solution based depositing of consecutive diode layers of said first organic light emitting diode. The method further comprises forming one or more charge injection layers (12, 14) on the first organic light emitting diode and forming a second organic light emitting diode (16) on the carrier by means of solution based depositing of consecutive diode layers of said second organic light emitting diode. The step of forming of the one or more charge injection layers comprises a step of performing atomic layer deposition for depositing at least one of the one or more charge injection layers. The invention further relates to an apparatus for manufacturing a stacked OLED and to a stacked OLED device.

System and method for making a vertical handover decision between first and second networks using a terminal configured to attach to both networks and a fixed point in either network. Both networks allow information flow between the terminal and the fixed point. When attached to the first network the terminal detects the second and compares a first bandwidth measurement, representing available bandwidth along a first path between the terminal and the fixed point, to a second bandwidth measurement representing available bandwidth along a second path between the terminal and the fixed point. The terminal maintains attach to the first network if the first bandwidth measurement is higher than the second bandwidth measurement and makes a decision to handover to the second network if the second band width measurement is higher than first bandwidth measurement.


The invention is directed at an exposure head for use in an exposure apparatus for illuminating a surface, the exposure head comprising one or more radiative sources for providing one or more beams, an optical scanning unit arranged for receiving the one or more beams and for directing the beams towards the surface for impinging each of the beams on an impingement spot, a rotation actuating unit connected to the optical scanning unit for at least partially rotating the optical scanning unit, wherein the impingement spots of the one or more beams are scanned across the surface by said at least partial rotation of the optical scanning unit, wherein the optical scanning unit comprises a transmissive element including one or more facets for receiving the one or more beams and for outputting the beams after conveying thereof through the transmissive element, for displacing the beams upon said rotation of the transmissive element for enabling the scanning of the impingement spots.


A fluid density measuring device uses a pipe with a pipe wall that has an inner wall surface with a non-circular cross-section at least in an axial segment of the pipe. Preferably, the inner wall surface comprises one or more protrusions extending inward into the pipe and along the axial direction of the pipe. An ultrasound transducer located on the pipe wall is used to generate local motion of the pipe wall with a circumferential direction of motion. Preferably, the ultrasound transducer is located between successive protrusions. An ultrasound receiver located on the pipe wall receives an ultrasound torsion wave generated by said local motion after the torsion wave has traveled through the axial section wherein the inner wall surface has a non-circular cross-section. The fluid density is determined from the propagation speed of the torsion wave.


A layerwise production method of a tangible object (8). A layer of uncured building material is provided onto a carrier (4, 30). Repeatedly, method cycles are performed, each comprising: providing layer data corresponding to an object layer, selectively exposing the layer of building material based on the layer data for curing thereof, and providing a next layer of building material onto the preceding layer. Each method cycle further includes verifying the cured preceding layer for identifying regions of insufficiently cured building material, and adapting a radiation dose locally for the next layer dependent on whether or not a location to be exposed in accordance with the layer data of the next layer coincides with one of the identified regions of insufficiently cured building material in the preceding layer.

A TFT device is manufactured starting from a substrate with mutually insulated elongated strips of semi-conductor material. A stack of layers over the strips on the substrate, the stack comprising a gate electrode layer. A multi-level resist layer is provided over the gate electrode layer. The multi-level resist layer defines gate and source drain regions, the channel running in parallel with the direction of the strips. Gate portions in the resist layer cross source drain regions in the resist layer, overreaching the source drain regions on either side at least by a distance corresponding to a pitch of the strips.
