Publication number: 20200200526Abstract: Methods, systems, and techniques for determining whether an event has occurred from dynamic strain measurements involve determining, using a processor, at least one event parameter from a signal representing the dynamic strain measurements, and then having the processor use the at least one event parameter to determine whether the event has occurred. The at least one event parameter is any one or more of a measure of magnitude of the signal, frequency centroid of the signal, filtered baseline of the signal, harmonic power of the signal, and time-integrated spectrum flux of the signal.Type: ApplicationFiled: February 28, 2020Publication date: June 25, 2020Applicant: Hifi Engineering Inc.Inventors: Seyed Ehsan Jalilian, John Hull, Daniel Huang, Adekunle Adeyemi

Publication number: 20200057220Abstract: There are described methods and systems for deploying optical fiber within a conduit. In one aspect, an optical fiber injector comprising a pressure vessel having a fluid inlet and a fluid outlet. The fluid outlet is engaged with an open end of the conduit. A length of optical fiber is provided within the pressure vessel. The optical fiber is then jetted into the conduit by injecting a fluid into the pressure vessel via the fluid inlet. The optical fiber injector is configured such that the fluid is directed from the fluid inlet to the fluid outlet, and urges the optical fiber to move through the conduit, thereby deploying the optical fiber within the conduit. In a further aspect, there is provided a modular assembly comprising a pipeline and a line of two or more conduits arranged end-to-end. Each pair of opposing ends of adjacent conduits is connected together by a separate splice box. The line is positioned along and adjacent to a length of the pipeline.Type: ApplicationFiled: February 9, 2018Publication date: February 20, 2020Inventors: John Hull, Neil Gulewicz, Robert Sokolowski, Alex Pletnyov, Souheil Merhi, Philip Cheuk, Seyed Ehsan Jalilian

Publication number: 20190256435Abstract: This disclosure provides a composting system and method. The system comprises: (a) a container configured to contain a composition and comprising (i) insulated walls, (ii) an air intake and (iii) a vent; and (b) a composition contained in the container. The composition comprises aerobic microorganisms, a carbon source and a nutrient source sufficient to support growth of the aerobic microorganisms. The container is sufficiently insulated so that heat generated by aerobic respiration is sufficiently retained in the container to maintain a heat gradient in the container. The container is dimensioned to generate a stack effect that moves air into the air intake, through the composition and out the vent. The moving air provides oxygen to support growth of aerobic microorganisms, making the stack effect self-sustaining as long as a carbon source and nutrients last. The insulation can maintain temperatures in the composting cell sufficient to kill pathogenic microorganisms.Type: ApplicationFiled: June 18, 2018Publication date: August 22, 2019Inventor: John Hulls
