Abstract: A Fabry-Perot interferometer includes a first mirror plate with a first semi-transparent mirror, a second semi-transparent mirror to define an optical cavity together with the first mirror, and one or more first supporting elements to support the first mirror plate, wherein the first mirror plate has a first substantially planar surface and a second substantially planar surface defining the maximum thickness of the first mirror plate, wherein the first mirror plate is bonded to the one or more first supporting elements by three or more joints, wherein each joint is bonded to the first mirror plate at a bonding region, wherein the distance between each bonding region and the first substantially planar surface is greater than 30% of the thickness of the mirror plate, and the distance between each bonding region and the second substantially planar surface is greater than 30% of the thickness of the mirror plate.

Abstract: A microfluidic chip device (MCD) and its use for performing miniaturized assays on magnetic microbeads (MMs) are described. The MCD is particularly useful for carrying out miniaturized transcript analysis by aiding affinity capturing (TRAC) assays, including PCR. The MCD comprises at least one reaction chamber with sealable liquid connections and at least one fluidic pillar filter in each chamber. The fluidic pillar filter comprises rods with spacings allowing MMs to pass. The sealable liquid connections feed liquid to the reaction chamber, wherein air bubbles are removed. The liquid stream contacts the MMs, which are manipulated with a magnetic rod. The liquid connections enable trapping of the MMs behind the pillar filters or in the channel, while the liquid is changed.

Abstract: The invention concerns an electrical impedance detector for measurement of physical quantities, in particular of temperature or humidity, as well as a process for manufacture of the detectors. The impedance detector is composed of pieces cut off from a continuous detector filament (20). The detector filament (20) comprises an electrically conductive pair of electrode wires (10a,10b) or an equivalent assembly of electrode wires, on/between which there is an active material (11) whose impedance properties are a function of the physical quantity to be measured. The different electrode wires (10a,10b) of the detector filament (20) in the pieces of detector filament (20) have been cut off at different points (41a,41b), compared with one another, so that the impedance (CM) to be measured will be formed in the area (CV) between the cut-off points (41a,41b) of the electrode wires (10a,10b).

Abstract: Electrical impedance detector for measurement of physical quantifies, in particular of temperature or humidity. The detector comprises conductor electrodes (10a, 10b; 10A,10W), between which the electrical impedance (C.sub.M) that represents the physical quantity to be measured is measured. Between the conductor electrodes (10a, 10b;10A, 10W) there is an active material (11;11P) whose impedance properties are a function of the physical quantity to be measured. The detector is composed of pieces cut-off out of a continuous detector filament (20; 20H;20K), which detector filament (20;20H;20K) comprises a conductive electrode wire or an assembly of electrode wires (10a, 10b; 10A, 10W), on/between which there is an active material (11;11P) whose impedance properties are a function of the physical quantity to be measured. Further, a novel process is described for the manufacture of said detectors.
