Patent number: 7878402Abstract: A method is provided for reading distorted optical symbols using known locating and decoding methods, without requiring a separate and elaborate camera calibration procedure, without excessive computational complexity, and without compromised burst noise handling. The invention exploits a distortion-tolerant method for locating and decoding 2D code symbols to provide a correspondence between a set of points in an acquired image and a set of points in the symbol. A coordinate transformation is then constructed using the correspondence, and run-time images are corrected using the coordinate transformation. Each corrected run-time image provides a distortion-free representation of a symbol that can be read by traditional code readers that normally cannot read distorted symbols. The method can handle both optical distortion and printing distortion. The method is applicable to “portable” readers when an incident angle with the surface is maintained, the reader being disposed at any distance from the surface.Type: GrantFiled: December 20, 2005Date of Patent: February 1, 2011Assignee: Cognex Technology and Investment CorporationInventors: Xiangyun Ye, Sateesha Nadabar

Publication number: 20100320272Abstract: An imaging module is supported by a housing of a reader for electro-optically reading indicia. The imaging module includes a solid-state imager having an array of image sensors for capturing return light from the indicia during reading. A laser scanning module is also supported by the housing and includes a scanner for scanning at least one of a laser beam from a laser and a field of view of a light detector in a scan pattern across the indicia during reading. A controller is operatively connected to the modules, and is operative for preventing reading interference between the modules during reading.Type: ApplicationFiled: August 10, 2010Publication date: December 23, 2010Inventors: Bradley Carlson, Edward Barkan, Vladimir Gurevich, Christopher Warren Brock

Patent number: 7855643Abstract: Some embodiments include observable properties triggered upon interrogation of RFIDs. The RFIDs can be passive RFIDs, and the observable properties can be visible changes that require little power to generate, and little or no power to maintain. The visible information can include information about items tracked with the RFIDs, such as shipping information. Some embodiments include passive RFIDs utilizing a single antenna to power an integrated-circuit chip and a visual identifier. Some embodiments include methods of locating interrogated RFIDs. Some embodiments include methods of tracking items.Type: GrantFiled: November 10, 2006Date of Patent: December 21, 2010Assignee: Round Rock Research, LLCInventor: John R. Tuttle

Patent number: 7845559Abstract: A hand-supportable digital image capture and processing system including a hand-supportable housing having an imaging window. A printed circuit (PC) board is mounted in the hand-supportable housing, and has front and rear surfaces and a light transmission aperture formed centrally therethrough. An image formation and detection subsystem has image formation optics for projecting a field of view (FOV) through the imaging window and upon an object within the FOV, and an area-type image detection array for forming and detecting 2D digital images of the object during object illumination and imaging operations. A first FOV folding mirror is supported above the rear surface of the PC board over the light transmission aperture, and a second FOV folding mirror is supported above the rear surface of the PC board and over the area-type image detection array. These mirrors fold and project the FOV through the light transmission aperture and the imaging window.Type: GrantFiled: December 21, 2007Date of Patent: December 7, 2010Assignee: Metrologic Instruments, Inc.Inventors: Anatoly Kotlarsky, Xiaoxun Zhu, Michael Veksland, Ka Man Au, Patrick Giordano, Weizhen Yan, Jie Ren, Taylor Smith, Michael V.
