A track state of a tracked object within a sensor field-of-view (FOV) of the follow-on object is initialized. Target-state estimator (TSE) processing based on sensor measurements from the sensor FOV is performed to maintain the track state of the tracked object. Kinematic characteristics of the tracked object are evaluated based on the sensor measurements to compute a probability that the tracked object is an LO based on the evaluated kinematic characteristics. If the probability is not greater than a threshold, the tracked object is designated as the target and TSE processing is resumed. Otherwise, the tracked object is designated as an LO and the track state is re-initialized and the track of the LO is excluded from some intercept task considerations.

  • Patent number: 10578565
    Abstract: A method and system for scanning an elongate structure. A scanner in a scanning system is moved axially along the elongate structure using a translating structure in the scanning system. The elongate member is scanned axially as the scanner moves axially along the elongate structure. The scanner is moved rotationally around the elongate structure at a location in which an inconsistency is detected at the location during an axial scan. The elongate structure is scanned rotationally at the location while the scanner moves rotationally around the elongate structure.

  • Patent number: 10527547
    Abstract: The invention relates to a method and to a device for determining a material property, in particular the aging state or the aging resistance, of a bitumen material, comprising the steps: applying a substantially monochromatic first excitation radiation of a first excitation wavelength to the bitumen material; measuring the intensity of a first fluorescence radiation, excited by the first excitation radiation, at a measurement wavelength; applying a substantially monochromatic second excitation radiation of a first excitation wavelength to the bitumen material; measuring the intensity of a second fluorescence radiation, excited by the second excitation radiation, at the measurement wavelength; determining a first key figure for the material property of the bitumen material from the ratio between the intensity of the second fluorescence radiation to the intensity of the first fluorescence radiation.

  • Patent number: 10520609
    Abstract: A system of particle detectors can determine the location of a source without rotations or iterations. Embodiments of the system may comprise a middle detector flanked by two shield plates, with two side detector panels exterior to the shields. The middle detector may be positioned toward the front and orthogonal to the side detectors. By comparing a ratio of the detector data to a predetermined angular correlation function, the system can determine both the sign and magnitude of the source angle in real-time. Embodiments of the system can rapidly and automatically localize sources including nuclear and radiological weapons materials, whether in vehicles or cargo containers, and can provide improved sensitivity in walk-through personnel portal applications, enable enhanced detection of hidden weapons by a mobile area scanner, and enable a hand-held survey meter that indicates the radiation level as well as the location of the source of radiation.

  • Patent number: 10502697
    Abstract: A method, apparatus, and system for scanning an elongate structure. A scanner in a scanning system is moved axially along the elongate structure using a translating structure in the scanning system. The elongate structure is scanned axially using an x-ray beam emitted by the scanner as the scanner moves axially along the elongate structure to perform an axial scan. The x-ray beam has a first orientation. A location on the elongate structure having an inconsistency is detected while scanning the elongate structure axially. The elongate structure is scanned at the location with the x-ray beam in a second orientation.

  • Patent number: 10466367
    Abstract: A neutron detection system may include a neutron detection device located outside of a reactor vessel. The neutron detection device may be configured to detect neutrons generated within the reactor vessel. A containment region located intermediate the reactor vessel and a containment vessel may be configured to house a containment medium. A neutron path device may be at least partially located between the reactor vessel and the containment vessel, and the neutron path device may be configured to provide a neutron path to the neutron detection device through a neutron path medium contained within the neutron path device. A neutron attenuation coefficient associated with the neutron path medium may be smaller than a neutron attenuation coefficient associated with the containment medium.

  • Patent number: 10459092
    Abstract: A muographic observation instrument is constructed with a ground unit in which six gaseous detectors are attached to six detector sockets arranged to be parallel to a flat surface with a certain distance between them, and a pair out of ten radiation shields is placed between each detector socket mounted the shield sockets. Since the gaseous detectors have smaller spatial resolution compared to a usual scintillator detector, the thickness of lead plates used for eliminating the noise caused by electromagnetic shower from the horizontal direction can be made ? smaller, and therefore the weight of the whole device is decreased substantially. Furthermore, since only the gaseous detectors and radiation shields have to be mounted to the sockets of the ground unit, the installation of the device is simple.

  • Patent number: 10401311
    Abstract: The present invention provides a method and a device for measuring a formation elemental capture gamma ray spectrum, pertaining to the field of oil-gas exploration and well logging technologies. The method comprises: performing moderation on neutrons emitted from a neutron source according to a neutron capture cross section of a test sample; and adjusting a relative location of the test sample with respect to the neutron source, so that a standard capture gamma ray spectrum of the test sample is measured and obtained at a location where a thermal neutron flux reacting with atomic nucleuses of the test sample reaches a first predetermined value. The present invention performs moderation on a neutron source according to neutron capture cross sections of different test samples to measure and obtain elemental capture gamma ray spectra of the test samples, thereby obtaining various formation elemental capture gamma ray spectra with higher accuracy.

  • Patent number: 10379252
    Abstract: Disclosed is a method and device for estimating weight of an object to be inspected in an inspection system. An effective atomic number and a high-energy gray value of the dual-energy corresponding to each pixel of the object to be inspected are obtained by a dual-energy radiation scanning. A mass-thickness value for a corresponding pixel is obtained from a pre-created mass-thickness attenuation curve by utilizing the effective atomic numbers and the high-energy gray value of the dual-energy for respective pixels. Weight information for at least a part of the object to be inspected is calculated by multiplying the mass-thickness value by the area of the pixel. Such a method may accurately calculate the weight of the object to be inspected and save the cost for a conventional weighing hardware.
