  • Patent number: 11408875
    Abstract: Disclosed is a method for detecting and identifying toxic and harmful gases based on machine olfactory. Information about the toxic and harmful gases is firstly collected through the machine olfactory system and then analyzed through a Selected Linear Discriminate Analysis (SLDA) combined with a Markov two-dimensional distance discriminant method to identify various toxic and harmful gases. The algorithm disclosed in the invention extracts the characteristic information of the sample data, and then fast processes and identifies the information as a linear recognition algorithm does, having wide applications in the field of machine olfaction, especially in detecting and identifying the toxic and harmful gases in real-time based on machine olfaction.

    Abstract: The invention provides a method and apparatus for of performing a test on a deluge system. The method comprises providing a gas source in fluid communication with a deluge system. A plurality of fluid sensors is installed at a plurality of locations (e.g. nozzles) in the deluge system. The gas source is activated to cause gas to flow through the deluge system during a gas test period, and using the plurality of sensors, at least one fluid parameter during the gas test period is measured to provide a gas test data set. The first gas test data set is stored, transmitted and/or processed to derive information about the condition of the deluge system.

  • Patent number: 10427938
    Abstract: A device and method detect cellular targets in a bodily source by utilizing a biofunctional pad comprised of a thin film of carbon nanotubes (CNT's). When antibodies are absorbed by the CNT's, cellular targets having markers matching the antibodies may be detected in a bodily source placed upon the biofunctional pad by measuring the conductivity of the thin film using conductive contacts electrically coupled to the thin film, as the binding of the receptors in the cellular targets to the antibodies changes the free energy in the thin film. In many respects, the device functions as a Field Effect Transistor (FET) with the bodily source, e.g., blood, acting as a polyelectrolyte liquid gate electrode to create a varying electrostatic charge or capacitance in the thin film based upon the binding of cellular targets in the source to the antibodies present on the biofunctional pad.

  • Patent number: 10372846
    Abstract: A method for modeling air pollution includes receiving a weather model for a particular geographic region. Satellite-observed pollution observation data over the geographic region is received. A physical dispersion model for pollution over the geographic region is generated using the received weather model. The received satellite-observed pollution observation data is interpolated to the generated physical model. The interpolated satellite-observed pollution observation data and the generated physical model are combined using weighted coefficients for both the interpolated satellite-observed pollution observation data and the generated physical model. The weighted coefficients are calculated in accordance with a relative error in both the physical dispersion model and the satellite-observed pollution observation data.
