Publication number: 20040125413Abstract: A method for printing a large invisible luminescent bar code on a mail piece addresses the problem of obscuration of modules by printed text such as the address. The bar code is printed large enough so that the line width of the characters is substantially less than the module size of the bar code components. Overprinting does not then completely obscure any module and so the bar code is still readable. The readability is especially enhanced by the high contrast of the luminescent image. When a fluorescent bar code is viewed under UV illumination, the bar code emits fluorescence in the areas of printed modules without text overprinted. Because the modules are wider than the text line width, the text does not completely obscure any module. The contrast of the bar code is reversed in fluorescence—that is, printed areas emit light.Type: ApplicationFiled: December 30, 2002Publication date: July 1, 2004Applicant: Pitney Bowes IncorporatedInventor: Robert A.

Patent number: 6478223Abstract: A color symbology, such as a bar code symbology, employs three or more colors to encode elements of one or more integer-widths. A light source or an appropriate filter of a color matched to one color of the symbology produces peaks in a reflectance signal produced from a light sensor, which receives light reflected from the symbol. Another, unmatched, color in the symbology produces valleys in the reflectance profile. A third or intermediate color produces a reflectance signal in a middle portion of the reflectance profile. By identifying the peaks and valleys in the profile, the portions corresponding to the intermediate color, may be found by measuring distances between centers of the peaks and valleys in the reflectance profile. As a result, all elements, of all colors in the symbol, may be decoded using a simple data collection reader, such as a laser scanner, employing only a single color laser.Type: GrantFiled: January 12, 2000Date of Patent: November 12, 2002Assignee: Intermec IP CorporationInventor: H.

Patent number: 6431447Abstract: This invention is related to a system and a method for reading high precision printed barcodes and their specification verification. The presented invention has a technique of reading both logistic sorting barcode (one or two dimension) and multi-layered structure barcode such as four-state barcode for automatic postal matter sorting. The invention also investigates height of high densely reduced barcodes in more than 3 steps, and precisely measures and reads the values of black bars thickness and white spaces. Previous techniques used laser beam for reading barcodes, but could not read barcodes, which have print density of less than 1/100 mm˜1/1,000 mm unit, and, it was also impossible to read precise specification values in case that barcode specification was composed of length unit indexes. The presented invention overcomes the previous said problems by using a laser diode array.Type: GrantFiled: February 8, 2000Date of Patent: August 13, 2002Assignee: Electronics and Telecommunications Research InstituteInventors: Moon Sung Park, Jae Gwan Song, Dong Chin Woo, Hye Kyu Kim, Chee Hang Park

Patent number: 6347741Abstract: A system for synchronization of the angular position of a rotating optical assembly in a bar code scanner having a rotating optical assembly. The optical assembly is rotated by a motor which produces a fixed number of pulses per rotation, the pulses occurring at equal intervals such that each pulse indicates a degree of angular rotation of the motor. The pulses are continuously monitored and counted. Timing is simultaneously monitored. A synchronization label is placed in the scanner such that light directed through the rotating optical assembly will strike the synchronization label and be reflected back to the rotating optical assembly when the rotating optical assembly is at a particular angular position, thus establishing an initial angular position of the rotating optical assembly. Once the initial angular position is established, timing is continuously monitored and pulses are continuously monitored and counted.Type: GrantFiled: July 10, 2000Date of Patent: February 19, 2002Assignee: NCR CorporationInventors: Denis M.
