Abstract: Method of in-situ focus-fusion is applied to focused and defocused images acquired by multi-layer spectral imaging of a depth dependent particulate sample, for constructing fused focused cube spectral image representations of the particles, thereby generating a focused image of each particle. A focus-fusion factor parameter is defined and calculated for combining (1) empirical particle physicochemical characteristics relating to (i) particle chemical composition and associated chemistry, and, (ii) particle morphology, with (2) empirical particle spectral characteristics relating to (i) image sharpness, (ii) signal-to-noise ratio (S/N), (iii) pixel intensity, (iv) spectral distances, and, (v) spectral fingerprints associated with spectral emission patterns of individual particles, and is used during image acquisition, target detection, image analysis, and, image classification. There is three-dimensional mapping of positions, sizes, and, emission spectra characteristics, of the particles. Particle physicochemical characteristics and parameters are correlated with particle spectral characteristics and parameters, using the fused focused cube spectral image data and spectral imaging calibration data.

Abstract: A current measuring apparatus comprises a current detection unit 10 and a photoelectric converter 20. The current detection unit 10 comprises an optical fiber sensor 11 extended or looped around a conductor 30. A reflective film 12 is attached to one end of the sensor 11 so that light can be reflected by the end of the sensor. The current detection unit 10 further comprises a first Faraday element 13, a light-transmitting birefringent member 14, a first optical fiber 15, a second optical fiber 16 and a lens 17.  The Faraday element 13 rotates a plane of polarization of the incident light through about 22.5°. The birefringent member 14 functions to separate the light emitted from the sensor 11 into an ordinary ray L1 and an extraordinary ray L2 that are orthogonal to each other, and to transmit linearly polarized light L0 emitted from a light source. The lens 17 is provided between the element 13 and the birefringent member 14.  Focal points of the lens are formed at core portions of an input end 11a of the sensor 11 and an end face 15a of the first optical fiber 15. With this arrangement, the number of components is reduced and the apparatus is reduced in size.

Abstract: The present invention concerns a method for reducing seepage through a leak (5) in a duct (1), the leak being defined in terms of its maximum dimension xL  and its maximum width in an orthogonal direction yL and the effective size of the leak being given by formula (1): SL = (x2L + y 2L)1/2 . A plurality of sealing elements (3) are introduced into the duct, the sealing elements having dimensions a, b and c in mutually orthogonal directions and the effective size SE of the sealing element being given by formula (2) : SE = (a2+ b2 + c2) 1/2.  The sealing elements have an effective size SE, which is less than the effective size of the leak SL, so that sealing elements (3A) are drawn to the leak locality and caused, by reason of a pressure differential at that locality and attributable to the leak, to move over the leak and reduce the seepage.
