  • Patent number: 6634553
    Abstract: A method and apparatus use light sources, such as LEDs, to illuminate target areas. At least one embodiment of the invention provides a system for illuminating target areas using multiple light sources, wherein the system comprises a first light source configured to illuminate a first target area. The system further comprises a second light source configured to illuminate a second target area, wherein the second target area is located more distant from the second light source compared to the distance from the second light source to the first target area. According to at least one embodiment, the illumination from the first light source and the illumination from the second light source overlaps on the first target area, and the intensities of the first and second light source are adjusted to provide a relatively balanced illumination of the first target area.

  • Patent number: 6611623
    Abstract: Information processing apparatus and method in which an objective image is acquired, and indentification information corresponding to specific image pattern is recognized from the objective image. It is determined whether the identification information recognized in local identification information for starting processing previously registered for each terminal, or any one of a plurality of code representing global identification information for starting processing common to all terminals. If the identification information is determined to be local identification information, the processing previously registered for each terminal is locally executed. If the identification information represents the global identification information, a request is made to a global code server that searches an associated global database having a plurality of stored codes and corresponding information, to execute the global processing corresponding to the identification information.

  • Patent number: 6585159
    Abstract: In the present invention, the control unit of an optical reader analyzes image data being generated by the imaging element of the reader and changes the mode of operation of the reader if the image data indicates that machine readable indicia, such as a bar code symbol or a text character, is likely in the field of view of the reader. Normally, analysis of image data includes the step of detecting for edge transitions in the image information. If the control unit determines that the image data includes more than a predetermined number of edge transitions, then the control unit imparts appropriate control over various reader elements to change the mode of operation of the reader. Normally, the control unit changes the mode of operation of the reader from a first mode, wherein the reader does not operate to decode or recognize image data to a second mode, wherein the reader operates to decode and/or recognize image data.

  • Publication number: 20030019934
    Abstract: An imaging module in one embodiment includes an aiming system having a light source, an aperture and an optical element positioned optically forward of the aperture wherein the aiming system projects a crisp and sharp aiming pattern onto a target over a wide range of distances. In one embodiment, an aiming system is configured so that a lens operates as an aperture to project a crisp sharp aiming pattern over a wide range of distances including distances at which the aiming pattern is less than optimally focused. In another embodiment an aiming system is configured so that light emanating from a thin aperture is imaged in such manner that a crisp, sharp aiming pattern is defined over a wide range of distances. The aiming pattern in one embodiment includes sharply defined lateral edges which are useful in sighting target indicia.

  • Patent number: 6419155
    Abstract: A laser beam scan type barcode reader which reads a pair of spaced marks which adjusts or specify corrects start and stop positions of the laser beam irradiation. The distance between the pair of marks corresponds to a length of a barcode to be read. The reader detects the start and stop positions of the laser beam irradiation determined by the pair of marks, and sets the detected start and stop positions of the laser beam irradiation. When the reader reads the barcode, it controls the turning on/off of the laser beam in one scan period based on the set start and stop positions of the laser beam irradiation, and determines the actual scan span in which the laser beam is turned on in the one scan period based on the start and stop positions determined by the pair of marks, which ensures preventing structural, functional and characteristic deviations of the reader from the standards from influencing the scan span of the laser beam.

  • Patent number: 6234393
    Abstract: A device for scanning a bar code symbol is adapted on a glove to be worn comfortably on an operator's bare or gloved hand. The glove includes a scan element on the back of the glove electrically connected to an activation switch disposed on a bottom finger tip of the glove. The activation switch triggers the scan element to scan a bar code by pressing the finger tip at a base of the bar code symbol to be read. Sliding the finger to turn on the scan element is a natural motion and does not interfere with normal use of the hand.

  • Patent number: 6223986
    Abstract: A data reading systems including an aiming aid system which creates a highly visible target or image in the scan volume at a preferred location for placement of the article to be scanned. In a preferred application, an overhead bar code scanner employs a rotating polygon mirror which scans one or more laser beams off pattern mirrors creating a complex pattern of scan lines down into the scan volume whereby the aiming aid is created by directing a laser beam onto a scanning mirror positioned on top of the polygon mirror generally along the rotational axis of the polygon mirror and then directing that beam out into the scan volume in the desired pattern, such as a circular aiming aid. Alternately, the aiming aid may be a multi-dimensional graphical image formed by holographic or diffractive optics.
