An apparatus for detecting an analyte in a sample, including a cell with at least one fixed electrode, at least one mobile electrode opposite the fixed electrode, the mobile electrode being configured to move with respect to the fixed electrode, and a sample receiving cavity defined by a space between the fixed electrode and the mobile electrode, wherein a surface of at least one of the fixed electrode and mobile electrode facing the sample receiving cavity is configured to bound a ligand of the analyte to be detected. The apparatus also includes a displacement mechanism configured to move the mobile electrode; and an external circuit connected to the fixed electrode and to the mobile electrode, and configured to measure a parameter having a value depending on the presence between the fixed electrode and the mobile electrode of the analyte to be detected.
摘要:
Information recording medium, reading apparatus for said medium and processes for implementing the apparatus. According to the invention, the material constituting the recording layer (15) is photoconducting. The apparatus comprises in particular a microprobe (20) and a light source (26) capable of subjecting the recording layer to a lit or unlit state. The resulting variations in resistivity are used to determine whether the read zone is amorphous or crystalline.
摘要:
A process for regulating the brightness of a microdot fluorescent screen and apparatus for performing this process. The screen is of the matrix type and is addressed by a scan of the rows, a pixel being formed at each row-column intersection. For an illuminated pixel, for a selection time T of the corresponding row, a quantity of charges is emitted by the associated microdots. The brightness is regulated during the selection time of each row by controlling the quantity of charges emitted by the microdots of each pixel to be illuminated, the charge quantity being identical for each pixel.
摘要:
Each image point X.sub.ij of the matrix screen is defined by the intersection between a control row i having at least one electrode and a control column j having an even number of electrodes. In order to eliminate the coupling between the rows and columns, the voltage signals applied to the electrodes of the same control column cancel one another out in groups of two.

Provided is a microfluidic device comprising a microfluidic substrate comprising at least one pathway for sample flow; and at least one thermal transfer member which is capable of cycling between at least two temperatures. The thermal transfer member is adapted to heat at least a portion of the sample pathway while a sample is flowing along said at least a portion of said sample pathway. Provided also are methods of carrying out biochemical protocols using such a device.
摘要:
An electron collector having an anode constituted by a substrate (21, 40, 41) on which are deposited conductive strips or tracks (23, 43). A dielectric material layer is deposited on at least one of the edges of each conductive strip.
摘要:
A flat display screen has a cathode including microtips for electronic bombardment associated with a gate, an anode including phosphor elements, and an inter-electrode gap. The screen includes an apertured insulating plate defining the inter-electrode gap associated with means for maintaining the plate apart from the anode.
摘要:
A dot matrix liquid crystal display having segment electrodes and common electrodes, a segment driver circuit and a common driver circuit, a multi-level power source, sensor resistors connected in series to the supply voltage bus lines for the segment electrodes, amplifiers for detecting and ampifying the voltage drop in the sensor resistors, and capacitors for capacitively coupling the common electrodes and the amplifiers. When the segment voltage is changed, the voltage change is sensed through the sensor resister and is fed back to the common electrode to reduce the induced noise on the common electrode.
摘要:
A dot matrix type liquid crystal display device having two groups of mutually crossing parallel electrodes sandwiching a liquid crystal layer, the electrodes of one group having an aperture at each electrode crossing area along the direction of and centrally at the electrode of the other group. The electric field at the aperture portion is constantly slanted to a predetermined direction to present uniform and wide stable display areas.
