Patent number: 7527203Abstract: Methods and apparatus are disclosed for selectively reading a barcode, symbol, or other indicia by either scanning the barcode with a flying-spot scanner, or by imaging the barcode, thereby improving reading performance by tailoring the reading method to the particular item that is being read. Both a flying-spot laser scanning front end and an imaging front end are incorporated in a single device. Data obtained by the selected reading method is decoded and output. A common decoder or separate decoders may be used to decode the data from the two front ends. A single image sensor may be shared between the flying-spot front end and the imaging front-end, with a limited readout area utilized for laser scanning. The size of the readout area may be adjusted based on detected target proximity. Selection of the reading mode may be based on criteria including manual input, the range of the target, or previous failed attempts to read the barcode using either reading method.Type: GrantFiled: July 10, 2007Date of Patent: May 5, 2009Assignee: Datalogic Scanning, Inc.Inventors: Edward C. Bremer, Alexander M. McQueen, Craig D. Cherry, Brad R. Reddersen, Steven A. McMahon

Patent number: 6505778Abstract: A multi-function optical reader comprises an photosensor, such as a charge-device (CCD), and signal conditioning and processing circuitry including separate channels for handling data in different formats. A bar code processing channel digitizes the scan signal according to light and dark features using a first-derivative technique, and an OMR processing channel uses an adaptive threshold to adapt to different light conditions and provide a boundary line for digitizing light and dark features of the target scan line. A feature measurement circuit measures the widths of the light and dark regions as derived by the separate processing channels, and provides the feature measurements to a decoding system or host terminal processor. The scan rate of the optical reader can be adjusted according to the data format to be read or the level of ambient light, to avoid saturation. The optical reader can provide multiple depth-of-field zones, both internal and external to an optical reader housing.Type: GrantFiled: September 8, 2000Date of Patent: January 14, 2003Assignee: PSC Scanning, Inc.Inventors: Brad R.

Patent number: 6069696Abstract: An object recognition system comprises a sensing apparatus for collecting light reflected from objects presented at a point-of-sale machine. The sensing apparatus includes a mechanism, such as a holographic disk or diffraction grating, for separating the color components of the light reflected from the object and directing, the color components onto an optical detector such as a two-dimensional imaging array, or a one-dimensional imaging array or single photo-sensitive optical cell used in conjunction with a rotating mirror. A pattern recognizer compares the spectral response, including the locations, amplitudes and widths of energy peaks of the different color components, against premeasured characteristics of known objects in order to classify the object. The weight of the object can be measured with a scale, and the density of the object calculated, with the weight and density being used by the pattern recognizer to further classify the object.Type: GrantFiled: June 7, 1996Date of Patent: May 30, 2000Assignee: PSC Scanning, Inc.Inventors: Alexander M.

Patent number: 5565668Abstract: An optical system and method for data reading having a light source which generates an optical beam directed toward an object to be read and a focusing system in the outgoing light path which establishes multiple beam functions. In a preferred application, a scanning system includes a multifocal lens having a single lens element having an inner lens portion of a first focal length and an outer annular lens portion with a second focal length, the optical system of a bar code scanner therefore establishing two separate focal positions from a single light source. Alternately, the system includes a focusing lens system with an corrector element disposed in the outgoing optical path, the corrector element having a plurality of optical zones, each zone having a different optical characteristic for modifying a portion of the outgoing optical beam. A zone may be a refractive region, a reflective region, a diffractive region, an empty region, a window region, or combinations thereof.Type: GrantFiled: June 7, 1995Date of Patent: October 15, 1996Assignee: Spectra-Physics Scanning Systems, Inc.Inventors: Brad R.
