  • Point-of-transaction workstation for electro-optically reading one-dimensional and two-dimensional indicia by image capture
    Patent number: 8579197
    Abstract: A solid-state imager is mounted at a point-of-transaction workstation for capturing images of one- and two-dimensional indicia and is operated at high speed to resist image blurring due to relative movement between the target and the imager. Dedicated hardware assistance and computation resources are allocated to decode multiple, continuous and simultaneous video streams from multiple imagers at the workstation.
    Type: Grant

  • Electro-optical reader with improved laser intensity modulation over extended working range
    Patent number: 7224538
    Abstract: The combination of a rooftop optical element and a soft edge aperture stop, as well as the introduction of a negative spherical aberration in a positive focusing lens, improve working distance and depth of focus in both moving beam and imaging readers for electro-optically reading indicia such as bar code symbols, especially for close-in symbols, and moreover tend to reduce undesirable light intensity modulation in the beam profile thereby improving reader performance.

  • Point-of-transaction workstation for electro-optical reading one-dimensional indicia, including image capture of two-dimensional targets
    Patent number: 7191947
    Abstract: A solid-state imager is mounted at a point-of-transaction workstation for capturing images of diverse targets useful for customer identification, customer payment validation, and operator surveillance. The imager is manually or automatically triggered and is operated at high speed to resist image blurring due to relative movement between the target and the imager.

  • Image capture system and method using a common imaging array
    Patent number: 6889904
    Abstract: An image of a target in a far-field range of working distances relative to an image capture system is focused at a first group of sensors in a common, two-dimensional, array of sensors, and an image of an optical code in a near-field range of working distances relative to the system is focused at a second group of sensors in the array. The same array is shared in a portable apparatus capable of capturing target images and optical code images without moving any optical components.
