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: 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).

Abstract: The instrument comprises a sensor (2) with a pair of spaced electrodes (4, 6), designed to be immersed in the fluid to form a capacitive measuring element and furnish a signal representative of the fluid's dielectric constant, the signal being processed to give an indication of the fluid's quality or degree of degradation. The electrodes extend in the same plane, with the fluid bathing both their faces on either side of the plane, and the signal from them is compared with a standard from electrodes (4ref, 6ref) of a reference capacitive component. The electrodes in both pairs are made from food grade steel, are comb-shaped, with interlocking parallel teeth, and are surrounded by a metal frame that acts as a screen against electromagnetic disturbance.

Abstract: The device uses micro-machining of layers to form the magnetic elements. The procedure for fabrication of inductive type components includes simultaneous micro-machining of a number of parts on a first substrate of magnetic material. Conductive tracks are formed on a multi-layer substrate and arms (8a,b,c) are placed over this, providing the support for a magnetic circuit. The conductive tracks end on contact pads (7a, 7b) which are part of the multi-layer substrate, but which are folded around on to the top of the magnetic circuit and glued in place. The resulting component is suitable for surface mounting.

Abstract: A device for transporting magnetic or magnetizable 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.
