    Abstract: A well integrity inspection system configured to inspect a well structure including multiple concentric layers. The well integrity inspection system includes an inspection probe positioned in the well structure. The inspection probe includes a plurality of excitation assemblies for transmitting a plurality of radiation emissions into the well structure. The plurality of excitation assemblies includes at least a neutron excitation assembly and an X-ray excitation assembly. The inspection probe also includes a plurality of detection assemblies configured to receive a plurality of backscatter radiation returns from the well structure. The plurality of detection assemblies includes at least a neutron detection assembly and an X-ray detection assembly. The well integrity inspection system further including a processor operatively coupled to the inspection probe. The processor is configured to determine a well integrity parameter of the well structure based on at least one of the plurality of backscatter radiation returns.

    Abstract: A route examining system includes first and second application devices, a control unit, first and second detection units, and an identification unit. The first and second application devices are disposed onboard a vehicle traveling along a route having conductive tracks. The control unit controls injection of a first examination signal into the conductive tracks via the first application device and injection of a second examination signal into the conductive tracks via the second application device. The first and second detection units monitor electrical characteristics of the route in response to the first and second examination signals being injected into the conductive tracks. The identification unit examines the electrical characteristics of the conductive tracks in order to determine whether a section of the route is potentially damaged based on the electrical characteristics.

    Abstract: A route examining system includes first and second detection units and an identification unit. The first and second detection units are configured to be disposed onboard a vehicle system traveling along a route having plural conductive tracks. The first and second detection units are disposed at spaced apart locations along a length of the vehicle system. The first and second detection units are configured to monitor one or more electrical characteristics of the conductive tracks in response to an examination signal being electrically injected into at least one of the conductive tracks. The identification unit includes one or more processors configured to determine that a section of the route includes an electrical short responsive to the one or more electrical characteristics monitored by the first and second detection units indicating that the examination signal is received by only one of the first and second detection units.

    Abstract: Systems for examining a route inject one or more electrical examination signals into a conductive route from onboard a vehicle system traveling along the route, detect one or more electrical characteristics of the route based on the one or more electrical examination signals, and detect a break in conductivity of the route responsive to the one or more electrical characteristics decreasing by more than a designated drop threshold for a time period within a designated drop time period. Feature vectors may be determined for the electrical characteristics and compared to one or more patterns in order to distinguish between breaks in the conductivity of the route and other causes for changes in the electrical characteristics.
