    Abstract: The invention provides a lab-on-a-chip device comprising a micro channel for a fluid, wherein the micro channel comprises a circumferential channel wall, wherein the channel wall comprises a first electrode, a second electrode, and a floating third electrode. The device can be used in a method for the analysis of an analyte fluid comprising flowing the analyte fluid through the channel of the electronic lab-on-a-chip device by measuring an electric signal between the first and the second electrode, especially measuring the electrical impedance between the first electrode and the second electrode. This may be used for instance for the analyses of mammalian semen.

  • Publication number: 20090059748
    Abstract: A method for setting an optimum value of a write power level for use in an optical recording apparatus for writing information on a recording layer (3) of an optical recording medium (1) by means of a radiation beam (5) is described. The recording layer is able to change between an amorphous and a crystalline state. The apparatus comprises a radiation source (4) for emitting the radiation beam (5) having a controllable value of a write power level (Pw) for recording information on the recording medium, a control unit (12) for recording a series of test patterns in a test area on the recording layer, each pattern being recorded with a different value of the write power level, a read unit (90) for reading the patterns and forming corresponding read signal portions, and first means (10, 101, 102) for deriving a value of a read parameter from at least one read signal portion and setting an optimum value (Popt) of the write power level based on the values of this read parameter.

  • Patent number: 7067338
    Abstract: ICs (20) are nearly separated from the semiconductor substrate (10) on/in which they are formed. Subsequently, the substrate is positioned upside down on a substrate (carrier) (3) which is provided with glue (21) at the location of a crystal. After attachment of the crystal to the carrier, the semiconductor substrate is removed and the crystal remains attached to the carrier e.g. at the crossing of rows and columns. The separate crystals may contain TFTs (simple AM addressing) but also more complicated electronics (address of pixel in memory+identification).

  • Patent number: 6960764
    Abstract: The performance of a scanning electron microscope (SEM) (10) is determined by scanning, with this SEM, porous silicon surface areas (PSF, PSC) each having a different average pore size, calculating the Fourier transform spectra (Fc) of the images of the surface areas and extrapolating the resolution (R) at a zero signal-to-noise ratio (SNR) from the width (W(1/e)), the signal amplitude (Sa) and the noise offset (NL) of the spectra. A test sample provided with the different surface areas is obtained by anodizing a silicon substrate (Su) at a constant electric current, while continuously decreasing the substrate area exposed to the etching electrolyte (El).
