A ladder-mounted ledge used for holding tools and materials. The ladder-mounted ledge provides a stable work surface, which minimizes the frequency of ascents and descents and facilitates efficient access to the tools and materials while using a ladder. The ladder-mounted ledge reduces the risk of falls during accessing the tools and materials, for example, various work tools, power tools, screwdrivers, and thereof. An embodiment of a first aspect, the ladder-mounted ledge comprises a body having an opening defined therein, a top surface, and a bottom surface. The body is configured to be removably attached to a ladder through the opening, with a ladder head positioned above the top surface of the body and ladder rungs positioned below the bottom surface of the body. The user can use the ladder-mounted ledge according to user preferences and application requirements.

A mobile scanning system and methods for inspecting contents of a container. Multiple detector plates are arrayed along an arcuate member coupled to a conveyance with wheels, capable of road travel. A source generates high-energy penetrating radiation that irradiates each of the detector plates from a single position. The arcuate member is disposed, during the course of operation of the system, in a vertical plane. The system has one actuator for rotating the arcuate member about a horizontal pivot into a horizontal plane, and a second actuator for further rotating the arcuate member, once rotated into the horizontal plane, about a vertical pivot, so that the arcuate member is contained, for purposes of transport, entirely within a volume defined by a rectangular prism that does not extend horizontally outward from the conveyance beyond any of its wheels.

Stowable arcuate detector array

Methods for inspecting contents of a container. High-energy penetrating radiation collimated into a fan beam illuminates an inspected container from one side, while a plurality of detector plates are disposed on the opposite side of the container. Each detector plate has a plurality of detector modules, each of which, in turn, is disposed on a remotely activated alignment and has multiple detector elements. A controller governs the orientation of each of the plurality of detector plates based at least on the detector signal generated by its detector elements such that each detector element of each detector module of each detector plate may be aligned to within a specified fraction of the transverse dimension of the fan beam as measured at the exit slot.
