    Abstract: Methods and apparatus for locating small indicia in large images are disclosed herein. An example method includes: identifying an aiming pattern zone that includes a detected or presumed location of an aiming light pattern, wherein an offset between the location and a center of image data varies due to a parallax; determining one or more coordinates of the aiming pattern zone; capturing image data representing an image of an environment appearing within a field of view (FOV) of a handheld scanner including the indicia; encoding the one or more coordinates into a tagline of the image; and providing the image with the tagline to an indicia decoder such that the indicia decoder attempts to decode the indicia from the image data starting in a region of the image data selected based upon the one or more coordinates.

    Abstract: Multiple focus ball bearing actuator calibration is disclosed herein. An example method includes focusing, using a ball bearing actuator, a lens to a first focus position to image a first target; recording, in a lookup table, a first distance and a first actuator code corresponding with the first focus position; focusing the lens to a second focus position to image a second target; recording, in the lookup table, a second distance and a second actuator code corresponding with the second focus position; calculating a plurality of focus positions for a plurality of distances over a total working range of the barcode reader using the first focus position and the second focus position, wherein the calculating is performed without a temperature correction factor; and recording, in the lookup table, the plurality of distances and a plurality of actuator codes corresponding to the plurality of focus positions.

    IPC: G06K7/10

    Abstract: A system and methods for providing aiming guidance for an imaging system. The system includes an illumination field source configured to provide illumination along a illumination optical axis to (i) illuminate a target and (ii) indicate a near field of view of the imaging system and a far field aiming source configured to provide a radiation pattern along an aiming optical axis to indicate a far field of view of the imaging system. Near field optics are configured to receive the first illumination from the near field illumination source and to form the first illumination to provide illumination to, and indicate to a user or machine vision system, the near field of view of the imaging system, and far field optics are configured to receive radiation from the aiming source and provide the radiation pattern to the far field to indicate the far field of view of the imaging system.

    IPC: G06K7/10

    Abstract: At least some embodiments of the present invention are directed toward optical arrangements for use in providing illumination light emitted by a barcode reader. In some embodiments, the arrangement includes an illumination source, a lens positioned within the path of the illumination light emitted by the illumination source where the lens is operable to collimate the light and redirect its central axis, and a window positioned within the path of the redirected and collimated light where the window is operable to alter the illumination light such that the resulting illumination light beam has a height-to-width ratio of less than 8 to 25.
