20120118974 | BARCODE READER WITH EDGE DETECTION ENHANCEMENT - An optical reader for decoding an encoded symbol character of a symbology includes a scan data signal processor having as an input a scan data signal encoding information representative of the encoded symbol character. The scan data signal processor includes a first time delay stage adapted to provide a primary phase waveform from the scan data signal, a second time delay stage adapted to provide an early phase waveform from the scan data signal, and a third time delay stage adapted to provide a delayed phase waveform from the scan data signal. The early phase waveform has a propagation delay less than the primary phase waveform, and the delayed phase waveform has a propagation delay greater than the primary phase waveform. The scan data signal processor further includes a peak window detection stage for generating a peak window timeframe when an amplitude of the primary phase waveform is greater than, less than, or equal to both an amplitude of the early phase waveform and the delayed phase waveform. The optical reader further includes a digitizer circuit adapted to accept, within the peak window timeframe, the scan data signal processor output. | 05-17-2012 |
20120211565 | USER-ADAPTIVE PRESENTATION SCANNER - A system for collecting data is provided that includes a presentation scanning apparatus comprising a first presentation scan window formed into a housing. A first laser source within the housing is operable to emit a first beam through the first presentation scan window along a first axis and illuminate a target comprising an encoded symbol character. A first scanning mirror is disposed intermediate the first laser source and the first presentation scan window. The first scanning mirror is operable to deflect the first beam emitted from the first laser source so that the first beam scans across the presentation scan window according to a baseline scan pattern. | 08-23-2012 |
20120228382 | DUAL LASER SCANNING CODE SYMBOL READING SYSTEM EMPLOYING AUTOMATIC OBJECT PRESENCE DETECTOR FOR AUTOMATIC LASER SOURCE SELECTION - Method of and system for reading code symbols a dual-laser scanning bar code symbol reading system having the capacity to automatically select in a user-transparent manner, and activate either a near-field source of laser illumination, or a far-field source of laser illumination, using an automatic object presence detection subsystem in the near-field portion of the laser scanning field. | 09-13-2012 |
20120284091 | INDICIA READER WITH FEEDBACK OF SCANNING THROUGHPUT - A method of operating an indicia reader including the steps of: consecutively reading a plurality of information bearing indicia (IBI) over a period of time; determining an operator of the indicia reader's performance based on the rate at which the plurality of IBIs are being read over the period of time; and, providing feedback to an operator of the result of the determining step. | 11-08-2012 |
20120318868 | BAR CODE SYMBOL READING SYSTEM EMPLOYING AN EXTREMELY ELONGATED LASER SCANNING BEAM CAPABLE OF READING POOR AND DAMAGED QUALITY BAR CODE SYMBOLS WITH IMPROVED LEVELS OF PERFORMANCE - A laser scanning bar code symbol reading system for scanning and reading poor quality or damaged bar code symbols. The system includes a housing having a light transmission window; an extremely-elongated laser beam production module for producing an extremely-elongated laser beam having (i) a direction of propagation extending along a z reference direction, (ii) a height dimension being indicated by the y reference direction, and (iii) a width dimension being indicated by the x reference direction, where x, y and z directions are orthogonal to each other. Each extremely-elongated laser beam is characterized by an elongation ratio (ER) that is defined as Y/X>4.5 for any point within the working range of the laser scanning bar code symbol reading system, extending along the z direction; where (i) Y indicates the beam height of the extremely-elongated laser beam measured in the Y reference direction, and X indicates the beam width of the extremely-elongated laser beam measured in the X reference direction, and (iii) the beam height (Y) and the laser beam width (X) are measured at 1/e | 12-20-2012 |
20140361082 | System and Method for Reading Code Symbols at Long Range Using Source Power Control - A system and method are presented for improving the performance of code scanners in the extended and far ranges. At these distances, the intensity of the laser beam reflected off the code symbol can be markedly decreased, thereby decreasing the likelihood of a successful reading of the code symbol by the code scanner. The system provides for dynamic power increases to the laser source to generate a greater dynamic range. | 12-11-2014 |
20150040378 | METHOD FOR MANUFACTURING LASER SCANNERS - A method for manufacturing laser scanners is provided. Laser scanners are configured to drive their light-deflecting assemblies at a fixed drive frequency. By selecting for inclusion in the laser scanners only those light-deflecting assemblies that have resonant oscillation frequencies falling within a specified range, operation of the laser scanners remains within engineering tolerances even through extreme environmental changes. Moreover, the method results in laser scanner having greater unit-to-unit consistency during operation even in extreme environments. | 02-12-2015 |
20150193645 | INDICIA-READER HAVING UNITARY-CONSTRUCTION - A hand-held indicia-reading device includes a housing and a cable having a unitary-construction. The indicia-reader has a head portion with an indicia-reading system including a printed circuit board. The entire handle portion of the reader is typically over-molded onto a host-connector cable. The host-connector cable includes a circuit board connector on one end and a connector for connecting to a host at an opposite end extending from a base portion of the handle. | 07-09-2015 |
