  • Patent number: 10317194
    Abstract: Spaced-apart light spots are projected in a light pattern on a target surface lying in a target plane. A range spot is projected at a position on the target surface to find a target distance to the target surface. An image of the target surface, light pattern, and range spot is captured along an imaging axis that is perpendicular to an imager plane of an imager. A controller determines an angular relationship between the imager and target planes based on the light pattern in the captured image, determines a scale relationship between the target surface and the imager based on the position of the range spot in the captured image, displays a compensated image of the target surface that is corrected in tilt by the angular relationship and in scale by the scale relationship, and determines dimensions of the target surface based on dimensions of the displayed compensated image.

  • Patent number: 10318778
    Abstract: Targets to be electro-optically read by image capture are illuminated with illumination light emitted from an illumination light source and directed along an illumination path through a window to the targets, and return light from the targets is captured through the window and projected along an imaging path to an array of light sensors of an imaging system. An optical element is located in both the illumination path and the imaging path, and has a light-reflecting, non-diffusing portion for directing the captured return light incident on the light-reflecting portion along a folded imaging path to the array, and a light-diffusing portion for diffusing the illumination light incident on the light-diffusing portion along a folded illumination path to scatter and blur an image of the illumination light source, to increase an apparent size of the illumination light source, and to reduce a perceived brightness of the illumination light source.

  • Patent number: 10306117
    Abstract: An imaging module for reading targets by image capture is mounted as a unitary assembly within an imaging reader. An imager is mounted on a first printed circuit board (PCB), and an interface connector is mounted on a second PCB. The first PCB is in supporting contact with first chassis walls of a chassis and is positioned to lie in a generally upright, first predetermined plane. The second PCB is in supporting contact with second chassis walls of the chassis and is positioned to lie in a generally tilted, second predetermined plane that is inclined at a tilt angle relative to the first predetermined plane. The first and second chassis walls are constituted as a one-piece support that maintains the tilt angle between the PCBs.

  • Patent number: 10261167
    Abstract: A method and apparatus for a co-located Radio Frequency Identification (RFID) device and ultrasonic device includes an RFID reader loop antenna element oriented parallel to a reflector panel. An ultrasonic emitter is disposed through an aperture in the reflector panel with a horn that extends through the loop element. The horn can serve as a mounting structure for the antenna element. A diameter of the aperture is less than one-quarter wavelength of an operating frequency of the RFID reader loop antenna element. The aperture is located in the reflector panel near a minimum E-field area of the RFID reader loop antenna element.

  • Patent number: 10249160
    Abstract: Successive products associated with targets to be electro-optically read are swiped, in their respective turns, past a window in a point-of-transaction workstation. A motion detector detects movement of each product. A reader electro-optically reads a target associated with each moving product. If the target associated with each moving product has not been read, then this event is deemed suspicious, and the event is flagged for a security investigation designed to deter product theft by sweethearting.

  • Patent number: 10242240
    Abstract: An imaging reader captures and analyzes image data, including raw captured image data, and analyzes that capture image data to decode indicia contained therein. The indicia may be one or more two-dimensional barcodes. A dedicated front-end controller of the imaging reader generates decode data for the indicia and combines the decode data with the image data using a combinational protocol, after which a resulting decode enhanced image data frame is communicated to a host processor for processing.

  • Patent number: 10244180
    Abstract: An imaging reader has near and far imagers for imaging illuminated targets to be read over a range of working distances. A range finder determines a distance to a target. A default imager captures a minor portion of an image of the target, and rapidly determines its light intensity level. At least one of the imagers is selected based on the determined distance and/or the determined light intensity level. The exposure and/or gain of the selected imager is set to a predetermined value, and an illumination level is determined, also based on the determined light intensity level and/or the determined distance. The selected imager, which has been set with the predetermined value, captures an image of the target, which has been illuminated at the illumination light level.

  • Patent number: 10198829
    Abstract: Image processing systems and methods are provided for extrinsic calibration of a plurality of image sensors. A logic circuit receives image data for an omnidirectional object from image sensors spaced apart and imaging at least a portion of a region of interest. The logic circuit combines the image data from the image sensors to generate a calibration matrix for the image sensors and to determine a matrix transformation data based on (i) reference image data and (ii) a three-dimensional model of the reference object. The logic circuit modifies the calibration matrix into an enhanced calibration matrix by applying the matrix transformation data to the calibration matrix, where the enhanced calibration matrix can be used to calibrate the plurality of image sensors.

  • Patent number: 10170920
    Abstract: Each charging member in a group identifies a docking connection. Each charging member, responsive to identifying the docking connection, transmits information to other charging members in the group and receives information transmitted from another charging member in the group. Each charging member generates a list using the information transmitted to the group and received from the group. Each charging member also includes a ranking component for filtering, sorting, and ranking entries in the list according to a predefined selection filter and/or ranking filter. Each entry in the list is associated with a charging member with a docking connection and in the group. Each charging member determines based on a predefined indication filter that an entry in the list that is associated with the charging member is ranked at a predefined position in the list and provides an indication.
