Patent number: 6386454Abstract: An area of interest is scanned to produce pixels of the scanned area. The pixels are divided into a plurality of blocks. For each block, an orientation of a spanning line or a lack of orientation is determined. Contiguous ones of the blocks are clustered, when their orientation is within a certain tolerance level. Each cluster has a length and a width. The length is longer than the width. If the orientation of a cluster's block is perpendicular to the length of that cluster, that cluster is selected as a bar code candidate.Type: GrantFiled: February 26, 2001Date of Patent: May 14, 2002Assignee: Accu-sort Systems, Inc.Inventors: Kurt Hecht, Milorad Neskovic, Vasanth Shreesha, Edward Cohen

Patent number: 6323503Abstract: An optical scanner utilizes two linear CCD detectors and a bandpass means to improve the ability of the scanner to discriminate against specular reflection. A coded symbology is illuminated by a noncoherent light source and light reflected from the coded symbology along a first path strikes the front face of the bandpass means. The bandpass means, functioning as a notch filter, transmits a select bandwidth of light while reflecting all other light onto a first CCD detector. Simultaneously, light reflected from the bar code symbol travels along a second path, at a different angle with respect to the plane of the coded symbology than the first path, is reflected from a mirror onto the back face of the bandpass means. The bandpass means transmits the select bandwidth of light onto a second CCD detector and reflects all other light. The second CCD detector has a notch filter which permits the detection of only the select bandwidth.Type: GrantFiled: May 28, 1999Date of Patent: November 27, 2001Assignee: Accu-Sort Systems, Inc.Inventor: Kurt Hecht

Patent number: 6206289Abstract: A scanner can read machine-readable code on an object. A scanner has a scanning device, a data device, and a registration device. The scanning device can repetitively scan the code and provide a scan signal repetitively corresponding to at least fragments of the code. The data device is coupled to the scanning device and responds to its scan signal for repetitively storing it. The registration device is coupled to the data device for reconstructing the code from at least two of the fragments of the code by relatively shifting the code fragments until they are in registration.Type: GrantFiled: June 7, 1995Date of Patent: March 27, 2001Assignee: Accu-Sort Systems, Inc.Inventors: Jeffrey G.

Patent number: 6193158Abstract: A system for high speed acquisition and decoding of a barcode symbol locates potential barcode candidates within a scanned image and filters the candidates to eliminate invalid data. The system permits computational resources to be focused on decoding information most likely to be an actual barcode symbol. Once a potential barcode candidate has been located, the barcode symbol is processed to determine the barcode orientation and symbology. Each element of the barcode symbol is then located, even if all elements are not visible in the original image, and the barcode symbol is decoded in accordance with the specific symbology.Type: GrantFiled: January 14, 2000Date of Patent: February 27, 2001Assignee: Accu-Sort Systems, Inc.Inventors: Kurt Hecht, Milorad Neskovic, Vasanth Shreesha, Edward Cohen

Patent number: 5979760Abstract: A scanner for reading barcode symbologies having a focusing illuminating source. The scanner uses a coherent light source for illuminating the coded symbol during a scan and a detector for collecting the reflected light energy from the coded symbol. Both the illuminating and collecting devices include lenses which are in variable spacial relationship with each other. The scanner varies the relationship between the light source and associated focusing lens to provide the narrowest focused beam at the barcode location.Type: GrantFiled: June 27, 1997Date of Patent: November 9, 1999Assignee: Accu-Sort Systems, Inc.Inventors: Christopher A.

Patent number: 5954913Abstract: 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.Type: GrantFiled: December 22, 1997Date of Patent: September 21, 1999Assignee: Accu-Sort Systems, Inc.Inventors: Albert Wurz, Edward P.

Patent number: 5940305Abstract: A moveable label printer-applicator/conveyor loader assembly for loading articles onto a conveyor comprises a frame mounted for movement along a conveyor path and a controller. The controller receives data from a host computer which specifies an article to be selected and actuates a drive motor to move the assembly to the selected bin location. The quantity of articles to be picked is displayed to an operator via a CRT display. Sensors detect the profile of articles loaded onto the conveyor and transmit this data to the controller. After the controller verifies that the correct article has been selected, a labeler prints and applies a label to each article.Type: GrantFiled: June 7, 1996Date of Patent: August 17, 1999Assignee: Accu-Sort Systems, Inc.Inventor: Albert Wurz

Patent number: 5900611Abstract: The present invention relates to a scanner for reading coded symbologies. The invention uses a coherent, visible light source for illuminating the coded symbol during a scan and a detecting means for collecting the reflected light energy from the coded symbol. The invention also employs an invisible light source illuminating the coded symbol during the scan and a one-dimensional position-sensitive detector whose field of view receives images of the illuminating beam. The position-sensitive detector outputs a current which is processed to detect the presence and compute the distance of an object being scanned. Both the visible and invisible light sources from the scanner travel along a shared, coaxial path to and from the object.Type: GrantFiled: June 30, 1997Date of Patent: May 4, 1999Assignee: Accu-Sort Systems, Inc.Inventor: Kurt Hecht
