Publication number: 20100177363Abstract: Systems and methods are provided for prioritizing an order in which to process a plurality of sub-regions of an acquired image of an optical code. A method of processing an optical code in a data reader comprises the steps of receiving data corresponding to a plurality of sub-regions of an acquired image of an optical code, processing according to a processing order the plurality of sub-regions for decodable data corresponding to the optical code, determining based on the step of processing the plurality of sub-regions whether one or more of the plurality of sub-regions contains decodable data, and if it is determined that a sub-region contains decodable data, increasing the processing priority associated with said sub-region. If one or more of the sub-regions having the highest processing priority contains decodable data, the remaining sub-regions do not need to be processed, which may save processing resources and increase the read throughput.Type: ApplicationFiled: January 5, 2010Publication date: July 15, 2010Applicant: Datalogic Scanning, Inc.Inventor: Weiyang Zhou

Publication number: 20100139989Abstract: Systems and methods are provided for reducing erroneous weighing of items by detecting items extending beyond a peripheral edge of a weigh platter associated with a data reader. For example, in response to a weigh request a scale guard module acquires data indicative of whether an item extends between the weigh platter and another surface, compares the acquired data to reference data, and based on the comparison, determines whether an item extends off the weigh platter and thus on to another surface. The scale guard module may utilize non-electromagnetic compression waves, radio waves, a portion of a data reader's scan field to scan a set of patterns extending along at least one edge of the weigh platter, an imaging based scanner to capture an image of at least one edge of the weigh platter, light beams extending along at least one edge of the weigh platter, or any combination thereof.Type: ApplicationFiled: December 9, 2009Publication date: June 10, 2010Applicant: Datalogic Scanning, Inc.Inventors: Charles Forrister Atwater, Alexander M.

Patent number: 7721966Abstract: Optical reading system and methods having multiple modes of operation, for example: omnidirectional and single-code picking; fixed and handheld reading; 1D and 2D code reading. In one configuration, an image-based system obtains input data via an area sensor (e.g., a 2D COD array) with only data corresponding to a pattern of virtual scan lines being stored and processed. A user may implement different operating modes such as a first mode reading codes in any location or orientation and a second mode reading only a code oriented along a particular virtual scan line or group thereof. Alternately, the data reader is operable to switch between handheld mode selecting a first pattern of virtual scan lines to process and/or decode and a fixed mode selecting a second pattern of virtual scan lines to process and/or decode. Virtual scan patterns in either mode can change from frame to frame.Type: GrantFiled: October 17, 2005Date of Patent: May 25, 2010Assignee: Datalogic Scanning, Inc.Inventors: Robert W.

Publication number: 20100123005Abstract: State-of-the-art optical scanning systems feature digital imaging of multiple symbolic labels such as optical bar codes. An imaging scanner reads a label 10 to 100 times faster than a conventional laser scanner because a group of items may be placed in the read zone simultaneously, or an item may bear multiple labels, thus allowing multiple symbolic labels to be captured in a single image. A preferred system/method is directed to a software-implemented “multiple label double read” protection scheme for preventing duplication errors in an advanced bar code reader using multiple fixed delay timers, with each timer being somewhat analogous to existing “single label double read” schemes. Determining the presence of duplicate data is accomplished by comparing label data or portions of label data to a set of recent buffered data representing the last N labels read and transmitted within a specified delay time.Type: ApplicationFiled: October 30, 2009Publication date: May 20, 2010Applicant: Datalogic Scanning, Inc.Inventors: Alan J.

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.

Publication number: 20090306924Abstract: A system and method for automatically calibrating a scale, particularly a scanner-scale of a POS system, in which the scale is calibrated via an on-board calibration system including an accelerometer that actually measures the acceleration due to gravity factor for a given location/time and then uses this measured factor to perform a calibration sequence. An example calibration method may include the steps of (a) performing an initial calibration on the scanner-scale during assembly; (b) providing the scanner-scale with an on-board accelerometer operable to measure gravity acceleration constants for the current location; and (c) running a calibration routine using the specific calibration data obtained from the measurement in step (b) to calibrate the scale. In one configuration, the system may also use other sensors, including temperature and humidity sensors, to provide further calibration constants for use in calibrating the accelerometer and the scale strain gage.Type: ApplicationFiled: May 5, 2009Publication date: December 10, 2009Applicant: Datalogic Scanning, Inc.Inventor: Bryan L.

Patent number: 7626769Abstract: An imaging system (FIG. 3) is disclosed that has a wavelength dependent focal shift caused by longitudinal chromatic aberration in a lens assembly (203) that provides extended depth of field imaging due to focal shift (213,214) and increased resolution due to reduced lens system magnification. In use, multiple wavelengths of quasi-monochromatic illumination, from different wavelength LEDs (206,207) or the like, illuminate the target, either sequentially, or in parallel in conjunction with an imager (200) with wavelength selective (colored) filters. Images are captured with different wavelengths of illumination that have different focus positions (208,209), either sequentially or by processing the color planes of a color imager separately. Extended depth of field, plus high resolution are achieved. Additionally, information about the range to the target can be determined by analyzing the degree of focus of the various colored images.Type: GrantFiled: March 22, 2007Date of Patent: December 1, 2009Assignee: Datalogic Scanning, Inc.Inventors: Bryan L.

Publication number: 20090206161Abstract: Various improved imager-based optical code readers and associated methods are disclosed herein. According to one embodiment, an imager-based method reads an optical code (which may be, for example, a linear optical code such as a bar code) on an object in a viewing volume. The method comprises dividing an image plane into a plurality of strip-shaped sections, viewing the object in the viewing volume from a plurality of perspectives, forming a plurality of strip-shaped images corresponding to the plurality of perspectives, respectively, thereby creating a composite image containing data from a plurality of perspectives, and processing at least a portion of the composite image so as to ascertain the information encoded in the optical code on the object in the viewing volume. Certain embodiments can mimic the performance of a laser-based scanner without a laser or moving parts but instead utilizing an electronic imaging device such as an imager.Type: ApplicationFiled: February 12, 2009Publication date: August 20, 2009Applicant: Datalogic Scanning, Inc.Inventor: Bryan L.
