  • Patent number: 6856440
    Abstract: A system for scanning objects having a linear array sensor, adapted to detect light input signals, is provided. A lens is optically connected to the linear array sensor, and is adapted to receive and transmit an optical image located in a field of view along a lens axis to the linear array sensor. A light source which generates an illumination stripe in general linear alignment with the lens axis is provided. A cylindrical lens is positioned between the light source and an object to be scanned. The cylindrical lens adapted to collect, transmit and focus light from the light source to form the illumination stripe.

  • Patent number: 6808115
    Abstract: The present invention provides an inexpensive scanner that can scan at near to medium focal lengths. A light beam is generated to illuminate a target area on the scanned object. A mirrored surface directs the light beam towards the object and light reflected from the object to a detector. The detector is positioned to receive a constant amount of reflected light from the mirrored surface.

  • Publication number: 20040124347
    Abstract: An optical scanning apparatus and method for scanning a surface of an object is provided. The scanner has an image sensor having a sensor plane and an image data output. An optics system defines an optical path having an axis and a first end whereat a scan object surface is locatable for scanning and a second end at the sensing plane. Preferably, the optics system includes a lens subsystem and a movable mirror for adjusting the length of the optical path. A linear actuator is coupled to the mirror such that movement of the mirror adjusts the focus of an optical image on the image sensor. A linear actuator is also operatively coupled to the image sensor to control the orientation of the plane of the image sensor relative to the optical path axis.

  • Patent number: 6053409
    Abstract: A focus changing apparatus for an optical scanner which increases the depth of the field of the optical scanner. The focus changing apparatus is optically located between a laser source and a scan mirror and includes a plurality of alternating curved and flat facets. Alternatively, a piezoelectric deformable mirror may be optically located between the laser source and a flat faceted scan mirror to provide for increased depth of field of the optical scanner.

  • Patent number: 5954913
    Abstract: A label applicator for applying a label to the top surface of an object moving along a path adjacent to the applicator. The applicator is comprised of a label printer mounted for vertical adjustment on support structure attached to a fixed frame. The printer has a label feed position and is adjusted vertically on the support to set the label feed position to an expected median article height. A label transport assembly, attached to the frame, receives and retains the label and then moves vertically and laterally from a home position, above the label feed position, to an article intercept position, where it applies the label to the moving article. The controller learns the home position and positions the label transport assembly at the home position to pick up labels. The label printer, the label transport assembly, and the moveable frame are located alongside the object path such that when the label transport assembly is in the home position, the object path is vertically unobstructed.
