  • Patent number: 12140570
    Abstract: A method and system for analysing a condition of a pipeline in real time is disclosed. The method and system comprise generating a transient pressure wave in fluid carried along the pipeline and detecting a transient pressure wave interaction signal responsive to the transient pressure wave where the pressure wave interaction signal has a time duration corresponding to a region of interest of the pipeline. The method and system further includes processing the transient pressure wave interaction signal to analyse the region of interest of the pipeline.
    Type: Grant

  • Patent number: 9097601
    Abstract: A method and system for assessing the condition of a pipe carrying a fluid is disclosed. The method includes the steps of generating a pressure wave in the fluid being carried along the pipe and detecting a pressure wave interaction signal resulting from an interaction of the pressure wave with a localized variation in pipe condition. The method then involves determining from the timing of the pressure wave interaction signal the location of the localized variation in pipe condition and the extent of the localized variation in pipe condition based on a characteristic of the pressure wave interaction signal.

  • Patent number: 7445934
    Abstract: A method and apparatus is described for estimating terminal purity or terminal contamination for a fluid during the withdrawal of the fluid from a subsurface formation. The apparatus and method provide for measuring refractive index of the fluid over a time period, fitting a curve through the refractive index measurements or data values derived therefrom and estimating a terminal refractive index or terminal value for the data values from the fitted to curve to estimate the terminal contamination or purity for the fluid.

  • Patent number: 7336348
    Abstract: An apparatus (10) for determining the viability of an egg, which apparatus (10) comprises shielding means (12, 14), emitting means (30) and detecting means (32), the arrangement being such that, in use, the shielding means (12, 14) inhibits exposure of an egg to background infra-red radiation, said emitting means (30) can emit electromagnetic radiation at infra-red wavelength(s) to impinge on the egg, and the detecting means (32) are positioned to detect at least a part of said electromagnetic radiation that has passed through the egg, the apparatus further comprising means for processing an output signal of the detecting means to determine whether there is a cyclical variation in the intensity of the infra-red radiation leaving the egg corresponding to action of a heart, the existence of said cyclical variation indicating that the egg is viable.

  • Patent number: 7289196
    Abstract: Determining the viability of an egg by: (a) causing electromagnetic radiation, having one or more wavelengths in the infra-red part of the spectrum, to impinge upon the egg; (b) receiving at least a part of the infra-red radiation that has passed through the egg and generating an output signal representative of the received infra-red radiation; and (c) processing said output signal to determine whether there is a cyclical variation in the intensity of the infra-red radiation leaving the egg corresponding to action of a heart, the existence of said cyclical variation indicating that the egg is viable; wherein step (a) is performed by directing infra-red radiation so that it passes through the shell for reflection from an outer surface of a vascular structure adjacent an inner surface of said shell, and step (b) is performed by receiving any infra-red radiation so reflected.
