  • Patent number: 10330541
    Abstract: The pressure-detecting system utilizes a nanocomposite sensor with quantum dots embedded in a matrix. Under pressure, both the quantum dots and the matrix fluoresce when illuminated by a laser. A spectroscope detects the intensity of each fluorescence and sends the information to a data processor. The data processor calculates a ratio using the intensities. Comparing this ratio to ratios stored in a data object in a database provides a value for the pressure detected by the sensor. The data object contains multiple ratios, each correlated to a specific pressure during a calibration process for the sensor. This calibration process subjected the sensor to known pressures, with the resultant ratios calculated and stored in the data object, correlated to the appropriate pressures.

  • Patent number: 10162079
    Abstract: Systems, methods, and devices for determining a neutron-gamma density (NGD) measurement of a subterranean formation that is accurate in both liquid- and gas-filled formations are provided. For example, a downhole tool for obtaining such an NGD measurement may include a neutron generator, a neutron detector, two gamma-ray detectors, and data processing circuitry. The neutron generator may emit neutrons into a formation, causing a fast neutron cloud to form. The neutron detector may detect a count of neutrons representing the extent of the neutron cloud. The gamma-ray detectors may detect counts of inelastic gamma-rays caused by neutrons that inelastically scatter off the formation. Since the extent of the fast neutron cloud may vary depending on whether the formation is liquid- or gas-filled, the data processing circuitry may determine the density of the formation based at least in part on the counts of inelastic gamma-rays normalized to the count of neutrons.

  • Patent number: 10123705
    Abstract: Coherent light is used to image cells/molecules at wavelengths in the near-infrared (NIR) region in second, third and fourth spectral windows. Optical attenuation from thin tissue slices of normal and malignant breast and prostate tissue, and pig brain are placed between matched bandpass filters, within desired windows and measured within an NIR spectral window at wavelengths selected to highlight the desired cells/molecules. Due to a reduction in scattering and minimal absorption, longer attenuation and clearer images can be seen in the second, third and fourth NIR windows compared to the conventional first NIR window. The spectral windows have uses in microscope imaging one or more collagens, elastins, lipids and carotenoids in arteries, bones, breast, cells, skin, intestines, bones, cracks, teeth, and blood due to less scattering of light and improved signal to noise to provide clearer images.

  • Patent number: 10122946
    Abstract: When detecting particulate radiation, such as electrons, with a pixelated detector, a cloud of electron/hole pairs is formed in the detector. Using the signal caused by this cloud of electron/hole pairs, a position of the impact is estimated. When the size of the cloud is comparable to the pixel size, or much smaller, the estimated position shows a strong bias to the center of the pixel and the corners, as well to the middle of the borders. This hinders forming an image with super-resolution. By shifting the position or by attributing the electron to several sub-pixels this bias can be countered, resulting in a more truthful representation.
