  • Patent number: 10359357
    Abstract: Video recordings from two or more optical channels are produced, processed, and analyzed simultaneously in order to provide quantitative analysis of action potentials, calcium transients and ionic flux in excitable cells loaded with voltage or ion sensitive dyes with distinct excitation and emission wavelengths. The specific wavelengths of fluorescent light emitted from each dye are separated and recorded. The recordings are mutually registered and cytometric analysis is performed to provide a quantitative analysis of the action potentials, calcium transient, and/or ionic flux on a cell-by-cell and well-by-well basis in microtiter plates. The cells are then fixed, labeled for other biomarkers, and scanned again. The resulting fixed cell images are registered with the live cell recordings and analyzed; missing cells that were washed off are detected relative to the live recordings, and cytometry data from live and fixed cell scans is collated cell-by-cell.

  • Patent number: 9985153
    Abstract: A photodetector has a photoactive layer of semiconducting inorganic nanoparticles positioned between a hole transport electron blocking layer of a first metal oxide and an electron transport hole blocking layer of a second metal oxide. The nanoparticles are responsive to electromagnetic radiation in at least the infrared region of the spectrum. The first metal oxide can be NiO, and the second metal oxide can be ZnO or TiO2. The metal oxide layers render the photodetector stable in air, even in the absence of an encapsulating coating around the photodetector. The photodetector has a P-I-N structure.

  • Patent number: 9939317
    Abstract: A sensitivity parameter storing portion stores, as known sensitivity parameters owned by a flame sensor, a reference received light quantity, a reference pulse width, a probability of regular discharge, and probabilities of non-regular discharge in advance. The discharge probability is calculated based on a number drive pulses applied to the flame sensor and a number of discharges determined to have occurred in the flame sensor having received the drive pulses. The calculated discharge probability and the known sensitivity parameters are used to calculate a received light quantity per unit time received by the flame sensor. A pulse width correcting portion is provided to correct the pulse width of the drive pulses generated by an applied voltage generating circuit so that the discharge probability equals a target discharge probability.

  • Patent number: 9939372
    Abstract: Video recordings from two or more optical channels are produced, processed, and analyzed simultaneously in order to provide quantitative analysis of action potentials, calcium transients and ionic flux in excitable cells loaded with voltage or ion sensitive dyes with distinct excitation and emission wavelengths, The specific wavelengths of fluorescent light emitted from each dye are separated and recorded. The recordings are mutually registered and cytometric analysis is performed to provide a quantitative analysis of the action potentials calcium transient, and/or ionic flux on a cell-by-cell and well-by-well basis in microtiter plates. The cells are then fixed, labeled for other biomarkers, and scanned again. The resulting fixed cell images are registered with the live cell recordings and analyzed; missing cells that were washed off are detected relative to the live recordings, and cytometry data from live and fixed cell scans is collated cell-by-cell.

  • Patent number: 9910022
    Abstract: The present invention provides a capability of Ion Mobility Spectrometry/Atmospheric Pressure Ionization Mass Spectrometry (IMS/MS) in the negative ion mode for Ozone detection and methods for ozone layer depletion monitoring in laboratory environment. Ammonium hydroxide vapors, as a dopant chemical, introduced to the inlet system of the IMS/MS interfaced with the reaction sphere enables ozone ionized to be O3?. The data obtainable from proposed methods show how ozone is depleted and which compound affect the most for O3 destruction among the O3 depletion substances of Chloro Fluoro Carbons (CFCs), Hydro Fluoro Carbons (HFCs), Hydro Chloro Fluoro Carbons (HCFCs), Hydro Chloro Bromo Carbons (HCBCs), and Hydro Chloro lodo Carbons (HClCs). Based on the results obtainable, more likely the IMS alone system without coupling with the mass spectrometer (IMS/MS) will rather be selected to develop as a spatial real time ozone layer depletion monitor.
