    Abstract: An apparatus for retaining magnetic particles in self-assembled magnetic particle structures in a liquid flow, comprises a micro-channel (5) and magnets (1,2) for generating a substantially static magnetic field across the micro-channel (5) such that magnetic particles (12) suspended in a liquid in the micro-channel (5) form magnetic particle structures (15). The micro-channel (5) has along its length transverse large sections (8) alternating with narrow sections (9). The large sections (8) are periodically distributed along and on either side of the narrow sections (9) so that in use magnetic particle structures (15) form across the large sections (8) of the micro-channel (5), the magnetic particle structures being retained by engagement of end parts (18) of the magnetic particle structures in the large sections (8) of the cell or channel (5). The apparatus is useful in particular in life science, chemistry and microfiltration applications by flowing through the micro-channel (5) a fluid carrying molecules or particles to be captured, filtered or activated by the magnetic structures (15).

    Abstract: The invention relates to a device for measuring the quality and/or degradation of a fluid, especially an oil, comprising a sensor consisting of at least one pair of electrodes which are distanced from each other. Said sensor is immersed in the fluid which is to be measured. The electrodes and the fluid form a capacitive element whose capacity varies according to the dielectric constant of the fluid. The sensor can provide an electric output signal representing said dielectric constant. The inventive device also comprises processing means which receive the output signal and which can determine the degree of quality and/or degradation of the fluid on the basis of said output signal. The invention is characterized in that the electrodes extend substantially on the same plane and in that the fluid surrounds the two surfaces of the electrodes on both sides of said plane.

    Abstract: A device for transporting magnetic or magnetisable microbeads (25) in a capillary chamber (14) comprises a permanent magnet (10) or an electromagnet (11) for subjecting the capillary chamber to a substantially uniform magnetic field, to apply a permanent magnetic moment to the microbeads (25). At least one planar coil (22) and preferably an array of overlapping coils are located adjacent to the capillary chamber (14) for applying a complementary magnetic field on the microbeads parallel or antiparallel to said substantially uniform magnetic field, to drive the microbeads. An arrangement is provided for switching the current applied to the coil(s) (22) to invert the field produced thereby, to selectively apply an attractive or repulsive driving force on the microbeads (25). The device is usable to transport microbeads for performing chemical and biochemical reactions or assay, as is done for instance in clinical chemistry assays for medical diagnostic purposes.

    Abstract: The method for producing inductive-type components, especially components of inductance coils, transformers or antennae, consists in micro-machining a plurality of first parts(1) that are joined to each other by connecting elements (2) or a connecting support on a first substrate that is made of a magnetic material; a printed multilayer plate (4,5) is inserted onto the arms (8a, 8b, 8c) of these first parts (1), whereby said plate has openings for the arms and metal windings that are terminated by at least two contact pads (7a, 7b); a second substrate made from a magnetic material is placed on top of and secured to the first substrate and the plate, whereby the second substrate is micro-machined prior thereto in order to obtain second parts (13) that are complementary to the first parts. The second parts are connected to each other by means of connecting elements or a connecting support. The components are then sorted and the contact pads on the lips (16,18) of the plate are folded against the base (9) of the core or the magnetic surface according to a special method of implementation in order to create a surface mounted device (SMD).
