摘要： Impedance spectroscopy is used to determine values associated with properties of a substance such as a fluid. In some embodiments, the present invention is applied to engine lubricants. A spectral matrix is constructed that comprises data taken from spectral plots. Also constructed is a result matrix comprising known quantities of a plurality of fluid constituents. A known analytic technique is performed on the spectral matrix to identify at least one principal component having significant influence on the spectral matrix. A reduced spectral matrix, wherein each column in the reduced spectral matrix is associated with a principal component having significant influence on the spectral matrix, is next created. A statistical technique uses the reduced spectral matrix and the result matrix to create at least one prediction equation. The prediction equation is used to predict at least one property in a second substance in situ.

摘要： The preferred embodiment of the invention disclosed herein comprises a closed glass member including a hollow pressure-sensing portion and a hollow pressure indicating portion communicating with the pressure-sensing portion. At least one wall forming the pressure-sensing portion is deformable and the pressure-sensing portion is filled with an incompressible fluid. In use, the glass member is placed in a capsule including a medium which when pressurized deforms the deformable wall which, in turn, exerts force on the incompressible fluid causing it to flow in the pressure-indicating portion. The level of the incompressible fluid in the pressure-indicating portion is indicative of the pressure in the medium.

摘要： A method and apparatus for evaluating and improving the properties of fluid formulations is disclosed. The inventive concept employs impedance spectroscopy (IS) measurements and data analyses to determine IS parameters of fluids representative of a fluid formulation. Correlations are determined between the IS parameters and the properties of the fluids, and a modified or new fluid formulation may be developed responsive to the correlations.

摘要： A probe having a pair of closely spaced electrodes is immersed in the lubricant and one electrode is excited with a relatively low voltage AC current. The frequency is swept over a range of about 1-10,000 Hertz and the current and phase angle measured at selected frequency intervals. The reactive (Z″) and resistive (Z″) impedances are computed for each current measurement and values of Z″ plotted as a function of Z′ as a Nyquist plot. The center of curvature of the plot between the origin and the minimum value of Z″ is located; and, the angle of depression of a line from the origin through the center of curvature ⊖ is determined from the plot. Samples of lubricant having known concentration of soot are measured and the angle ⊖ determined for each sample. The angle is then plotted as a function of soot concentration and a smooth curve fitted to the data plots. The curve may be programmed into a microcomputer to be used with the sensor for real time determination of soot concentration.
