20090180098 | Determining target distance in imaging reader - A target distance to a system target located at variable distances from an imaging system is determined by illuminating a calibration target at a calibration distance with a collimated light beam during a calibration mode of operation, by illuminating the system target at the variable target distance with the collimated light beam during an imaging mode of operation, by configuring the collimated light beam with a beam spot of a generally constant size during both modes of operation, by capturing return light of a calibration image size from the calibration target during the calibration mode, by capturing return light of a target image size from the system target during the imaging mode, and by determining the variable target distance based on the calibration distance, the calibration image size, and the target image size. | 07-16-2009 |
20100163625 | Minimizing misdecodes in electro-optical readers - An arrangement for, and a method of, minimizing misdecodes of GS1 DataBar Limited (Databar-limited) symbols in a reader for electro-optically reading symbols of different symbologies, such as Universal Product Code (UPC) Version A (UPC-A) symbols, includes a data capture assembly for capturing light from a target symbol, and for generating an electrical signal indicative of the captured light; and a controller for processing and decoding the electrical signal, and for determining whether the decoded signal is indicative of a Databar-limited symbol, and for determining whether the decoded signal has characteristics indicative of a different symbology, such as the UPC-A symbol, to indicate whether a misdecode of the Databar-limited symbol has occurred. | 07-01-2010 |
20100187314 | Arrangement for and method of reducing short reads in an imaging reader - An arrangement for, and a method of, enhancing performance of an imaging reader for imaging symbols to be read, include a solid-state imager supported by the reader and having an array of image sensors for capturing return light from a symbol as pixel data over a field of view, and a controller operatively connected to the imager, for mapping a virtual scan line in the field of view, for determining whether the virtual scan line extends entirely over the symbol, for remapping the virtual scan line as a remapped virtual scan line that extends entirely over the symbol upon determining that the virtual scan line extends partially over the symbol, and for decoding the pixel data that lies on the remapped virtual scan line. | 07-29-2010 |
20110024505 | METHOD OF SETTING AMOUNT OF EXPOSURE FOR PHOTODETECTOR ARRAY IN BARCODE SCANNER - A method and apparatus for setting the amount of exposure for the photodetector array in a barcode scanner. An image is captured with the photodetector array. The type for each sub-region in the multiple sub-regions in the image captured is determined. Each sub-region in the multiple sub-regions is assigned a weight based on the type of the sub-region. The amount of exposure for the photodetector array in the barcode scanner is set automatically based on the weight for each sub-region in the multiple sub-regions. In some embodiments, the predetermined image area are repartitioned into new multiple sub-regions based on the image captured, and the amount of exposure for the photodetector array in the barcode scanner is set automatically based on the weight for each sub-region in the new multiple sub-regions. | 02-03-2011 |

20150379709 | METHOD FOR ADAPTIVE COMPUTER-AIDED DETECTION OF PULMONARY NODULES IN THORACIC COMPUTED TOMOGRAPHY IMAGES USING HIERARCHICAL VECTOR QUANTIZATION AND APPARATUS FOR SAME - Provided are an apparatus and method for fast and adaptive computer-aided detection of pulmonary nodules and differentiation of malignancy from benignancy in thoracic CT images using a hierarchical vector quantization scheme. Anomalous pulmonary nodules are detected by obtaining a two-dimensional (2D) feature model of a pulmonary nodule, segmenting the pulmonary nodule by performing vector quantification to expand the 2D feature model to a three-dimensional (3D) model, and displaying image information representing whether the pulmonary nodule is benign, based upon the 3D model expanded from the 2D feature model, with duplicate information eliminated by performing feature reduction performed using a principal component analysis and a receiver operating characteristics area under the curve merit analysis. A textural feature analysis detects an anomalous pulmonary nodule, and 2D texture features are calculated from 3D volumetric data to provide improved gain compared to calculation from a single slice of 3D data. | 12-31-2015 |

20090001172 | Reading failure prevention in imaging readers - In an imaging reader for reading a coded symbol located in a range of working distances from the reader, a solid-state imager captures light from the symbol over a field of view, and a controller automatically determines whether an image of the symbol is located entirely within the field of view of the imager, and processes the symbol only when the symbol image is located entirely within the field of view of the imager. | 01-01-2009 |
20090050701 | Reader with Optical Character Recognition - An imaging-based bar code reader that includes an imaging and decoding system. Focusing optics and a sensor array define a field of view. A data processor has a memory for storing a pattern definition of previously imaged OCR characters and comparing a format of said previously stored characters to a present image to determine a character content of the present image. | 02-26-2009 |

20090318788 | DETECTION OF CANCER MARKERS - The present invention relates to combining surface molecular imprinting (SMI) with the production of self-assembled monolayers (SAM) of hydroxyl alkanethiolate molecules on gold coated chip surfaces. In this technique, the sensing element is placed on the transducer and the whole assembly can then be miniaturized and integrated into a smart chip. These sensors can detect, nanomolar quantities of complex biomolecules. | 12-24-2009 |
