A container includes multiple panels defining an interior volume, with a first panel including a composite material. A first beam detector element positioned within the interior volume detects a directed radiation scan beam that includes a modulated query message. Also positioned within the interior volume are a security element to detect an intrusion and an identification element communicatively coupled to the first beam detector element to store an identity of the container and to produce a query response message without breaking a seal of the container. A transmitter element is coupled to the identification element to transmit a response message to a receiver unit. The beam enters the inter volume along a path directed through the first panel, across a portion of the interior volume and onto the first beam detector element allowing for determination of a material property of contents of the interior volume.

The present specification discloses a high speed scanning system for scanning cargo carried by rail. The system uses of a two-dimensional X-ray sensor array with, in one embodiment, a cone-beam X-ray geometry. The pulse rate of X-ray source is modulated based on the speed of the moving cargo to allow a distance travelled by the cargo between X-ray pulses to be equal to the width of the detector, for a single energy source, and to half the width of the detector for a dual energy source. This ensures precise timing between the X-ray exposure and the speed of the passing object, and thus accurate scanning of cargo even at high speeds.

Systems and methods for automated security inspection and routing of in-transit objects are described. In one embodiment, a plurality of security screening devices are provided, each operable to output screening data of an in-transit object, including a first screening device located in a sealed environment of a vehicle for transporting the object towards a conveying system, including one or more measuring devices operable to measure screening parameters of the object when located in the sealed environment, and a second screening device in combination with conveying and routing components of the conveying system used to transport said objects from an ingress point through a conveyor junction to reach the second screening device. A control unit is assigned to the conveyor junction, wherein the control unit is configured to receive security data assigned on the basis of the screening data from the first screening device to the object upstream of the conveyor junction, and in response, to determine and set a routing direction on the basis of the assigned security data, whereby the object is directed downstream to a screening route for further screening by the second screening device, or to a loading route for objects cleared for loading. Other embodiments are also described and claimed.

Among other things, one or more systems and/or techniques for segmenting a representation of a sheet object from an image are provided herein. To identify elements of an image (e.g., pixels and/or voxels) representative of sheet objects, a constant false alarm rate (CFAR) score and a topological score are computed for respective elements being analyzed. The CFAR score indicates a relationship between an element and a neighborhood of elements when viewed as a collective unit. The topological score indicates a relationship between the element and a neighborhood of elements when viewed neighbor-by-neighbor. When the CFAR score is within a specified range of CFAR scores and the topological score is within a specified range of topological scores, the element is labeled as being associated with a sheet object. A connected component labeling (CCL) approach may be used to group elements labeled as being associated with a sheet object.

An x-ray scanning system includes an x-ray source that produces a collimated fan beam of incident x-ray radiation. The system also includes a chopper wheel that can be irradiated by the collimated fan beam. The chopper wheel is oriented with a wheel plane containing the chopper wheel substantially non-perpendicular relative to a beam plane containing the collimated fan beam. In various embodiments, a disk chopper wheel's effective thickness is increased, allowing x-ray scanning with end point energies of hundreds of keV using relatively thinner, lighter, and less costly chopper wheel disks. Backscatter detectors can be mounted to an exterior surface of a vehicle housing the x-ray source, and slits in the disk chopper wheel can be tapered for more uniform target irradiation.
