  • Arrangement for and method of processing products at a workstation upgradeable with a camera module for capturing an image of an operator of the workstation
    Patent number: 10460574
    Abstract: A bioptical workstation captures images of illuminated symbols with a solid-state imager. The workstation is field-upgradeable by installation of a camera module in the workstation away from the imager. The camera module captures an image of the operator through an upright window. The captured image of the illuminated symbol and the captured image of the operator are independently processed. The image of the operator is captured only with ambient light.

  • Dimensioning system for, and method of, dimensioning freight in motion along an unconstrained path in a venue
    Patent number: 10451405
    Abstract: A ranging system captures successive point clouds from moving freight, and a tracking system tracks successive positions and orientations of the moving freight. A computing device correlates each successive point cloud with each successive position and orientation and time of the moving freight, combines the correlated point clouds to obtain a composite point cloud of the moving freight, and processes the composite point cloud to dimension the moving freight. Once the freight is dimensioned, it may, for example, be efficiently loaded into a container.
