Patent number: 8453934Abstract: A technique and a light emitting device that can smoothly read out data while tracking a position of the light emitting device (an object). The light emitting device expresses data with “a change in the change of a color (switching of changes)”. The light emitting device specifies an object and the position thereof with a first primary change and thereafter expresses data with, so to speak, a secondary change (switching of the primary change). The primary change means that G and B alternately turn on (indicated by G*B) and so on. The secondary change means a change from the condition (G*B), in which G and B alternately turn on, to the condition (B*R) in which B and R alternately turn on. Thus, since data is expressed by the change of color condition changes, it is easier to freely express data while the position of an object is specified.Type: GrantFiled: February 16, 2011Date of Patent: June 4, 2013Assignee: B-Core Inc.Inventor: Akiteru Kimura

The analyte sensor has a body and a plurality of machine-readable colored codes associated with the body. The colored codes may contain red, green, and blue hues, which are discernable into coded information. The coded information may include the analyte sensor model, analyte sensor calibration constant, expiration or manufacture date of the analyte sensor, analyte sensor counterfeiting codes, warnings, messages to the user, etc. Colored code reading systems, apparatus and methods for reading such color-coded information associated with the analyte sensor are provided, as are numerous other aspects.Type: ApplicationFiled: May 13, 2010Publication date: November 18, 2010Applicant: BAYER HEALTHCARE LLCInventors: Paul M. Ripley, Xin Wang, Narasinha Parasnis, Swetha Chinnayelka

Publication number: 20100252636Abstract: A method that lays a certain restriction on a distance between color areas and carries out “cutting out” and “sequence recognition.” In an optical recognition code which aligns a plurality of cells to predetermined color is affixed and denotes a data by a sequence of colors, distance between the cells is stipulated to allow an easier reading-out of the code. A distance between the cells contiguous to each other is > a predetermined minimum value and < a predetermined maximum value. The distance between one of the cells and another of the contiguous cells is shorter than a distance between the one of the cells and another of the noncontiguous cells. Under these conditions, it is possible to read out the optical recognition code in the sequence of the cells by sequentially tracing the near-positioned cells with the distance as a clue.Type: ApplicationFiled: April 8, 2010Publication date: October 7, 2010Applicant: B-CORE INC.Inventor: Akiteru Kimura

Patent number: 7793853Abstract: A method of reading and decoding scrambled and encoded two-dimensional data represented on a sheet of media as a dot matrix includes the step of detecting a data area on the sheet of media by detecting targets on the sheet of media. A bit pattern represented by the dot matrix is detected and written to generate a byte pattern. The byte pattern is descrambled to generate coded data and the data is decoded.Type: GrantFiled: August 16, 2006Date of Patent: September 14, 2010Assignee: Silverbrook Research Pty LtdInventors: Kia Silverbrook, Paul Lapstun, Simon Robert Walmsley

Patent number: 7795491Abstract: Surgical sponges and other articles are provided with machine-readable information which provides a serial number or other unique identification of the sponge. In addition, the machine-readable information will provide the type of article and/or a characteristic visual motif associated with the article. That way, by scanning in the machine-readable information from the sponges or other articles prior to a procedure, the computer or other digital processor can determine which articles may be missing after the procedure and alert the surgical team as to the type and/or characteristic visual motif of the missing article.Type: GrantFiled: February 3, 2006Date of Patent: September 14, 2010Assignee: Patient Safety Technologies, Inc.Inventors: Brian E. Stewart, Nicolas Soichet

Publication number: 20100213259Abstract: Systems and methods of optical code reading include production of image data by a color image sensor array and processing of the image data to decode an optical code. In one configuration, the color image sensor array includes first and second sets of sensor pixels sensitive to light having wavelengths within, respectively, first and second wavelength bands, reflected light is focused by an optical system to form an image of an optical code on the color image sensor array, first and second sets of image data representing light intensity levels sensed by, respectively, the first and second sets of sensor pixels are produced, and the first set of image data is processed to determine whether the second set of image data is to be used in combination with the first set of image data to decode the optical code.Type: ApplicationFiled: February 18, 2010Publication date: August 26, 2010Applicant: Datalogic Scanning, Inc.Inventor: WenLiang Gao

Publication number: 20100123009Abstract: An optical code reader includes a color image sensor array having first and second sets of pixels arranged along multiple parallel axes of a first axes group and multiple parallel axes of a second axes group transverse to the first axes group. The pixels of the first set produce data representing sensed light intensity values. In one configuration, the optical code reader includes a single-axis interpolator to produce interpolated intensity values that correspond to selected locations of pixels of the second set. The single-axis interpolator is operable to produce an interpolated intensity value for a selected location by using only intensity values sensed by pixels of the first set that share an axis of the first axes group with the selected location.Type: ApplicationFiled: November 3, 2009Publication date: May 20, 2010Applicant: Datalogic Scanning Inc.Inventor: Craig D.

Patent number: 7688469Abstract: A computer object such as text, graphics, mathematical formulas, images, audio, and other data and information handled inside a computer or through a computer in industry or daily life etc. is expressed, recorded, reproduced, and transmitted using color or a color numerical value. Color is used as a medium for expressing data or information taking note of the characteristics of color. This helps counter the ballooning amount of recording. Color can also be used to prepare codes.Type: GrantFiled: December 30, 2005Date of Patent: March 30, 2010Assignee: Tani Electronics CorporationInventor: Okie Tani
