  • Publication number: 20030047597
    Abstract: Methods of and systems for illuminating objects using planar laser illumination beams having substantially-planar spatial distribution characteristics that extend through the field of view (FOV) of image formation and detection modules employed in such systems. Each planar laser illumination beam is produced from a planar laser illumination beam array (PLIA) comprising an plurality of planar laser illumination modules (PLIMs). Each PLIM comprises a visible laser diode (VLD, a focusing lens, and a cylindrical optical element arranged therewith. The individual planar laser illumination beam components produced from each PLIM are optically combined to produce a composite substantially planar laser illumination beam having substantially uniform power density characteristics over the entire spatial extend thereof and thus the working range of the system.

  • Publication number: 20030019938
    Abstract: An improved counter-top bar code scanner is equipped with a bump protection mechanism and a scan angle adjustment mechanism. The bump protection mechanism is provided in the form of a protective sheath fabricated of a shock-absorbing material. The scan angle adjustment mechanism is provided in the form of a movable bracket adjustably mounted to the scanner housing. If the bracket is mounted to a fixed surface, the bracket remains fixed but permits adjustments of the housing to any of the plurality of positions relative to the fixed surface.

  • Publication number: 20020100804
    Abstract: An ergonomic single-line compact laser bar code scanning system having a compact housing for hand-held disposition at a counter. The scanning system is automatically-activated and includes a bar code symbol reading mechanism contained within a hand-supportable housing having a manually-activatable data transmission switch. During symbol reading operations, the bar code symbol reading mechanism automatically generates a visible laser scanning pattern for repeatedly reading one or more bar code symbols on an object during a bar code symbol reading cycle, and automatically generating a new symbol character data string in response to each bar code symbol read thereby. During system operation, the user visually aligns the visible laser scanning pattern with a particular bar code symbol on an object (e.g., product, bar code menu, etc.) so that the bar code symbol is detected, scanned, and decoded.

  • Publication number: 20020030107
    Abstract: A bar code scanner for either fixed or hand-held disposition at a counter. The scanner includes a compact housing including a spherical head with a window and a downwardly protruding stem, and a sliding carriage attached to the base of the stem. The stem and sliding carriage cooperate with arcuate guide rails in the compact base for positioning the window via pivoting the head about a horizontal axis.

  • Publication number: 20010045465
    Abstract: An optical scanner comprising an automatic (i.e., triggerless) portable bar code symbol reading device with an omnidirectional scanning engine mounted within the head portion of its housing, and adapted for use with an associated base unit. The bar code symbol reading device produces a confined scanning volume for omnidirectional scanning of code symbols presented therein, while preventing unintentional scanning of code symbols on nearby objects located outside of the confined scanning volume.

  • Patent number: 6299067
    Abstract: A fully automatic bar code symbol reading system having an automatic (i.e., triggerless) portable bar code symbol reading device with an omnidirectional projection laser scanning engine mounted within the head portion of its hand-supportable housing, and an associated base unit positioned within the data transmission range thereof without a physical wiring connection thereto. The hand-supportable bar code symbol reading device produces a narrowly confined scanning volume for omnidirectional scanning of code symbols presented therein, while preventing unintentional scanning of code symbols on nearby objects located outside thereof.
