  • Patent number: 10768100
    Abstract: A plurality of monitoring devices are arranged at different heights and steps, and infrared reflective assemblies of the monitoring device are set at different heights to collect infrared spectral data of chemical constituents of the air mass that are being diffused in airspace of different heights. The pollution factors contained in the air mass and the pollution level of each factor are learned by using IR spectrum for qualitative and quantitative analysis on the pollution factor, therefore realizing continuous monitoring in a certain area. Artificial duty is not required while 24-hour continuous intelligent monitoring can be achieved. Besides, meteorological data are collected in combination with the meteorological data collected by the meteorological information acquisition module at different heights and calculation is made based on the air diffusion model of various pollution factors to finally determine the position of air pollution source.

  • Patent number: 10765382
    Abstract: The present invention discloses a method for reconstructing dynamic PET concentration distribution image of dual-tracer based on stacked autoencoder. The invention introduces deep learning into dynamic tracer PET concentration distribution image reconstruction, and the process is mainly divided into two stages of training and reconstruction. In the training phase, train multiple autoencoders using the concentration distribution images of mixed tracers taken as input, and the concentration distribution images of the two tracers taken as labels to build the stacked autoencoder. In the reconstruction phase, the concentration distribution images of the individual tracer can be reconstructed by inputting the concentration distribution images of the mixed traces to the well trained stacked autoencoder.

  • Patent number: 10690783
    Abstract: A radon measurement device includes a housing, a diffusion chamber, a diffusion chamber sensor, a diffusion pathway, a clock circuit, measurement circuitry, and a triggering mechanism. The diffusion chamber is disposed in an internal cavity of the housing. The housing includes a vent. The diffusion chamber sensor detects radioactive decay of radon and generates an electrical signal. The diffusion pathway enables introduction of ambient air into the diffusion chamber. The clock circuit outputs time data. The measurement circuitry receives the electrical signal and associates therewith a particular time datum. The triggering mechanism selectively isolates the vent from an environment and selectively triggers the measurement circuitry. Responsive to a triggering action on the triggering mechanism, the diffusion pathway is fluidly connected with the environment and functionality of the measurement circuitry is initiated.

  • Patent number: 10670512
    Abstract: The Intrinsic Hyper-Spectral Flow Cytometer (IHSFC) and its associated methodology, improves current flow cytometry by eliminating the need of associated hardware-based elements currently used for spectral data detection. The (IHSFC), rather than using narrow band lasers to excite or interrogate the analytes, the flow stream is excited by a wide wavelength range beam. The raw data generated by the (IHSFC) are as follows; forward light scatter, right angle light scatter, coherent spectral data and non-coherent spectral data. The intrinsic fluorescent spectral components are extracted from the coherent and non-coherent spectral data.
