A microfluidic cartridge for placement onto a parallel pneumatic interface plate of a pneumatic instrument is provided. The cartridge includes a three dimensional fluid channel, in which a fluid is to be transported, a flexible membrane that spans a plane and is part of an outer surface of the cartridge. The three dimensional fluid channel is spatially defined in three dimensions by internal walls of the cartridge and by the flexible membrane. The flexible membrane is in a ground state, when no pressure or vacuum is applied to the flexible membrane. However, the flexible membrane is pneumatically deflectable from the ground state perpendicular to the plane of the flexible membrane in two directions when the cartridge is placed onto the parallel pneumatic interface plate.

A device for inserting wires and/or pipes in a tubular, flexible sheath includes a sleeve (11), with a split (111) made therealong. The sleeve (11) is encircled by a cylindrical tubular body (21) also having made therealong a relative split (211). The sleeve (11) can turn inside this cylindrical tubular body (21), so as to define two working positions, first (H1) and second (H2). In the first working position (H1), the split (111) of the sleeve (11) corresponds to the split (211) of the tubular body (21), so that the wires can be inserted into the device. In the second working position (H2), the split (211) of the tubular body (21) is closed by the sleeve (11), so as to block the wires inside the device. A rounded, wedge-shaped member (23) rising over the cylindrical tubular body (21) is to be slidably fitted in the flexible sheath (F). The profile of the member (23) allows to open the edges of the elements (3) of the sheath, so as to insert the wires thereinside.

A portion of at least one electrode is in contact with a respective conducting portion so as to provide a means of external electrical connection to the electrode(s). The conductive portions and non-conductive portions of the housing are co-moulded. This sensor has a relatively small number of component parts and is relatively cheap and easy to manufacture. It also provides a cheap and reliable way of forming external electrical connections to the electrodes.

The recess is at least partly arranged and at least partly embedded in a layer of paint of the blade-surface. The recess is established by a former plate, which is arranged on the surface of the blade before the blade-surface is painted and while the recess is established by removing the former plate after the painting is finished.

Methods for producing air gap-containing metal-insulator interconnect structures for VLSI and ULSI devices using a photo-patternable low k material as well as the air gap-containing interconnect structure that is formed are disclosed. More particularly, the methods described herein provide interconnect structures built in a photo-patternable low k material in which air gaps are defined by photolithography in the photo-patternable low k material. In the methods of the present invention, no etch step is required to form the air gaps. Since no etch step is required in forming the air gaps within the photo-patternable low k material, the methods disclosed in this invention provide highly reliable interconnect structures.

An electrically conductive gel in the housing interior about the plastic housing outer periphery (and preferably including carbon particles or carbon fibers) is in intimate contact with the distribution circuit and the metal coating. And a thermally conductive gel is disposed between the at least one electronic component and the housing closed end interior surface, and preferable includes particles of at least one of the group of aluminum oxide, aluminum nitride, and boron nitride.

It is disclosed a circuit for extracorporeal blood treatment in which a flow-inverting device is interposed between a blood treatment unit and a blood pump placed on an artery branch connected with a vascular access of a patient. The flow-inverting device allows the blood flow within the filtering unit to be kept unchanged even following an inverted circulation in the patient-side artery and vein branches controlled by the blood pump.

A system for supervising the speed of at least one engine of an aircraft includes three independent information sources determining first, second and third values for an aerodynamic parameter of the aircraft and precision information indicating the precision of these values. A control unit acts on the operation of the engine, and a sensor measures a fourth value for the parameter. An arithmetic unit selects a control value by using the first, second, third and fourth values of the aerodynamic parameter and the precision information and uses the control value to determine a control sequence for the control unit. An information transmission network, to which the three independent information sources and the arithmetic unit are connected, permits a transmission of information between the sources of information and the arithmetic unit.

Described is a device for inducing crystal nucleation in a crystalliser. The device comprises a vessel for fluid and a surface abrader, wherein the surface abrader is configured to abrade a surface within the vessel to induce crystal nucleation. The friction of the abrader against the surface within the vessel creates nano-sized particulates which induce crystal nucleation. Crystal growth can then take place in the crystalliser. Also described is a crystallisation apparatus comprising the device and a crystallisation process using the device or similar. The device is significantly cheaper and more reliable than known ultrasound devices and facilitates the separation of crystal nucleation and crystal growth. The device also enables the avoidance of the use of seeding as a source of secondary nucleation.
