  • Patent number: 10571597
    Abstract: Systems and methods are provided for scanning an item utilizing an X-ray scanner in order to facilitate a determination of whether the X-ray radiation penetrated through the entirety of the scanned item. Various embodiments comprise a conveying mechanism, an X-ray emitter, a detector, and an X-ray penetration grid (XPG). The XPG may comprise a radiopaque grid that may serve as a reference for determining whether radiation passes through the scanned item, the grid oriented such that the grid members are neither parallel nor perpendicular to the direction of travel. Such orientation may minimize or eliminate “ghosted” radiation signals included in a visual display of the radiation received by the detector. A scanned item may be oriented with the XPG such that radiation emitted by the X-ray emitter that passes through a portion of the scanned item must also pass through the XPG before being received by the detector.

  • Patent number: 10511828
    Abstract: Projector with rolling illumination to incrementally project a pattern over a scene within an image sensor FOV. Only a portion of the FOV is illuminated by the projected pattern at any given instant in time. The image sensor may be operable with a rolling shutter to incrementally collect a frame of image data representative of the scene. The projection roll position and rate may be synchronized with the roll position and rate of the image sensor shutter so that the portion of a scene illuminated by the projector at any given instant in time spatially overlaps the portion of the scene being sampled by the image sensor. When a shutter has rolled through one complete integration cycle over a frame time, the pattern projector has also rolled through one complete illumination cycle. Lower projector duty cycles associated with rolling illumination may enable more efficient operation and/or higher on-state radiant intensities.

  • Patent number: 10413259
    Abstract: An imaging system generates a first radiograph based on a first pattern of radiation detected by a Linear Diode Array (LDA) radiation detector positioned to detect a radiation beam emitted by a radiation generator. The LDA radiation detector comprises a plurality of modules. Each respective module of the plurality of modules comprises a respective plurality of photodiodes corresponding to pixels. Furthermore, the imaging system may determine, based on the first radiograph, a size of a gap between two of the modules of the LDA radiation detector. After determining the size of the gap, the imaging system may generate a second radiograph based on a second pattern of radiation detected by the LDA radiation detector. The imaging system may generate a third radiograph by modifying, based on the size of the gap, the second radiograph to compensate for the gap.

  • Patent number: 10416341
    Abstract: Methods and systems are disclosed for the deployment and operation of shipping container scanning systems that enables scanning of containers passing through a modern, highly automated port without impeding the flow of commerce. Locating the scanners where container dwell time is already longest, and configuring scanners to scan up to several containers in parallel but under separate scanning control, minimizes any delay associated with scanning. Operationally integrating scanning systems with the automated logistical port systems ensures smooth, delay-free operation. Controlling the flow of information so that scanning results, including but not limited to images and assessments of the presence or absence of threat material or contraband, are sent only to government Customs and/or security facilities adjacent to but separate from the port insulates port operators from involvement in activities that could slow container throughput.
