There is described a handheld inspection device for inspecting an infrastructure having a structure wall at least partially supported into material such as soil. The handheld inspection device generally has a portable frame; a high energy photon source mounted to said portable frame and having a radioactivity level below a threshold radioactivity level; a scattered photon detector mounted to said portable frame and having a field of view diverging towards said target region of said infrastructure and encompassing at least a portion thereof, said scattered photon detector detecting scatter events incoming from said target region during a given period of time, and generating a signal indicative of scatter events detected during said period of time; and a controller receiving said signal generated by said scattered photon detector; and generating an integrity indication associated to said target region of said infrastructure based on said received signal.

There is disclosed a device for use in evaluating the integrity of soil behind a wall of an infrastructure. The device generally has a frame having a plurality of rests adapted to be received onto the wall during use; a hammer assembly having an actuator fixedly mounted to the frame and a hammer element having a head movably mounted to the frame, the actuator being actuatable to move the head to strike the wall while the plurality of rests hold the frame in a fixed position relative to the wall; and a sensor configured and adapted to sense vibrations of a portion of the wall resulting from the strike and to generate a vibration signal indicative thereof.

The method of inspecting a degraded area of a metal structure covered by a composite repair generally comprises operating a Compton scattering inspection device onto the degraded area, including emitting a beam of radiation particles directed towards and across the composite repair, detecting at least some backscattered photons scattered back from the metal structure, and acquiring Compton scattering data from the detected backscattered photons, the Compton scattering data being indicative of remaining wall thickness of the degraded area.

The method is for inspecting an infrastructure having a corrugated pipe at least partially surrounded by soil. The corrugated pipe has a cylindrical wall which is corrugated along a length thereof and forming a longitudinally extending series of corrugations. The method generally has the steps of emitting, outwardly from the interior of the corrugated pipe, a beam of radiation particles directed towards a given voxel positioned beyond an inner face of the cylindrical wall and along a scanning plane parallel to an orientation of individual ones of the corrugations of the cylindrical wall; detecting backscattered photons scattered back from the given voxel and along the scanning plane; and generating inspection data based on the detected backscattered photons associated with the given voxel for use in inspecting the corrugated pipe.

The design is the visual features of the DISPLAY SCREEN WITH GRAPHICAL USER INTERFACE, having variable width and length, as shown in solid lines in the drawings, whether those visual features are features of shape, configuration, pattern or ornament, or any combination of those features.Fig. 1 is a first variant of the DISPLAY SCREEN WITH GRAPHICAL USER INTERFACE;Fig. 2 is a second variant of the DISPLAY SCREEN WITH GRAPHICAL USER INTERFACE;Fig. 3 is a third variant of the DISPLAY SCREEN WITH GRAPHICAL USER INTERFACE;Fig. 4 is a fourth variant of the DISPLAY SCREEN WITH GRAPHICAL USER INTERFACE.The portions in dashed lines do not form part of the design. The variable width and length of the DISPLAY SCREEN WITH GRAPHICAL USER INTERFACE varies consistently within the break lines.

There is described a method and apparatus for collecting Tomographic inspection data of objects using Compton scatter radiation. The apparatus is of size and weight for portable use within industrial facilities and may be used for assessing integrity of infrastructures in terms of material density, missing materials, thickness of materials, and identification of foreign materials.

There is described a method for inspecting a structure across a cover layer covering the structure. The method generally has emitting a high energy photon beam along a photon path extending across said cover layer and leading to a target point within said structure, resulting in scattering along at least first and second scatter paths originating from said target point and extending across said cover layer and away therefrom, said first and second scatter paths forming a respective angle relative to said cover layer and defining an inspection plane comprising at least the target point; simultaneously detecting a first scatter signal incoming from said first scatter path and detecting a second scatter signal incoming from said second scatter path, and generating first and second values indicative therefrom; comparing said first and second values to one another; and inspecting said structure based on said comparing.
