  • Patent number: 12038393
    Abstract: Systems and methods inspect a fastener installed at least partially through a hole in a part, by measuring fastener concentricity, measuring fastener flushness with a surface, and/or detecting foreign object debris near the fastener. Systems include an x-ray imaging system, a first camera device, a second camera device, a first support structure, and at least one processing unit. The first camera device produces a first image of the fastener from a first vantage point, and the second camera device produces a second image of the fastener from a second vantage point, such that a 3D image of the fastener can be created from the first image and the second image. The system inspects the fastener based on the x-ray image and/or the 3D image, to determine concentricity and/or flushness of the fastener. Systems may be automated and mounted on robot arms to be positioned relative to the fasteners being inspected.

  • Patent number: 12038553
    Abstract: A system identifying a source of radiation is provided. The system includes a radiation source detector and a radiation source identifier. The radiation source detector receives measurements of radiation; for one or more sources, generates a detection metric indicating whether that source is present in the measurements; and evaluates the detection metrics to detect whether a source is present in the measurements. When the presence of a source in the measurements is detected, the radiation source identifier for one or more sources, generates an identification metric indicating whether that source is present in the measurements; generates a null-hypothesis metric indicating whether no source is present in the measurements; evaluates the one or more identification metrics and the null-hypothesis metric to identify the source, if any, that is present in the measurements.

  • Patent number: 12029141
    Abstract: A photon-number-resolving detector comprises a detection element, an ohmmeter, and a hardware logic component. The detection element can be formed from a Weyl or Dirac semimetal. Electrons of the detection element are characterized by a surface state that exhibits a Dirac cone and a bulk superconducting state that exhibits a bandgap. When photons having energies less than the bandgap of the bulk superconducting state impinges on the detection element, the photons can be absorbed by electrons of the detection element that are characterized by the surface state. The ohmmeter outputs resistance data indicative of an electrical resistance of the detection element while the photons impinge on the detection element. The hardware logic component can determine, based upon the resistance data, a number of the photons that are absorbed by the surface state electrons of the detection element.
