  • Patent number: 10948471
    Abstract: In some embodiments, data from multiple vehicle-based natural gas leak detection survey runs are used by computer-implemented machine learning systems to generate a list of natural gas leaks ranked by hazard level. A risk model embodies training data having known hazard levels, and is used to classify newly-discovered leaks. Hazard levels may be expressed by continuous variables, and/or probabilities that a given leak fits within a predefined category of hazard (e.g. Grades 1-3). Each leak is represented by a cluster of leak indications (peaks) originating from a common leak sources. Hazard-predictive features may include maximum, minimum, mean, and/or median CH4/amplitude of aggregated leak indications; estimated leak flow rate, determined from an average of leak indications in a cluster; likelihood of leak being natural gas based on other indicator data (e.g. ethane concentration); probability the leak was detected on a given pass; and estimated distance to leak source.

  • Patent number: 9714941
    Abstract: The invention provides a bio-sensing nanodevice comprising: a stabilized biologically-derived G-protein coupled receptor—the olfactory receptor—on a support, a real time receptor-ligand binding detection method, an odorant delivery system and an odorant recognition program. The biologically-derived G-protein coupled receptor can be stabilized on nanotechnology using surfactant peptide. The said nanodevice provides a greater surface area for better precision and sensitivity to odorant detection. The invention further provides a microfluidic chip containing a stabilized biologically-derived G-protein coupled receptor—the olfactory receptor—immobilized on a support, and arranged in at least two dimensional microarray system. The invention also provides a method of delivering odorant comprising the step of manipulating the bubbles in complex microfluidic networks wherein the bubbles travel in a microfluidic channel carrying a variety of gas samples to a precise location on a chip.

  • Patent number: 9696259
    Abstract: A system for obtaining a measurement of a species of interest. The system includes one or more reference regions, a sensor region, an exciter unit, a detector unit and a processing unit. The exciter unit exposes first and second chemical transducers in the reference and sensor regions, respectively, to an excitation light while they are exposed to reference environments and an analyte, respectively. The detector unit measures responses of the first and the second chemical transducers to the excitation light. The processing unit determines a compensation for aging of the first chemical transducer from a discrepancy between the measurements of the responses of the first chemical transducer and reference responses. The processing unit applies the compensation for aging to the measurement of the response of the second chemical transducer to obtain the measurement of the species of interest in the analyte.
