Abstract: An imaging window cover and slotted hinge assembly includes a cover and first hinge members rotatably and slideably coupled to second hinge members. The cover and slotted hinge assembly enables the cover to be attached to a housing so that the cover may be located in any position between a fully covering position and a rotated and stowed position. When rotated and stowed, the cover and hinge assembly are fully located below a plane of the imaging window, and fully out of the way so that large objects may be placed over the imaging window.

Abstract: A verifier apparatus including a linear imaging unit for an iterative capturing and collecting of data sample sets of linear image data, along with a position value that is associated with each collected data sample set. A preferred method calls for a post processing of collected data sample sets and position values to yield imaging data representing a plurality of evenly spaced and parallel imaging lines, which may then be processed to determine one or more print quality attributes.

Abstract: A method for adjusting an object distance for focusing upon a face of an item, including a data carrying graphical that is placed within a field-of-view of a fixed focal length imaging device. The method employs using parallax focusing techniques to produce a laser spot indicator, and further calls for providing a fixed on-screen focusing target to indicate a location to which the laser spot indicator must be moved and positioned before in-focus imaging activities can be realized.

Abstract: A verifier imaging unit structured with a movably mounted imaging device, housed within a housing of the imaging unit, such that the orientation of the imaging device may be altered so that the imaging device may be placed in one of a number of available and pre-established imaging orientations. Each available imaging orientation has an associated imaging window, and a support surface provided about or proximate to the imaging window. The imaging window and support surface enable the placing, distancing, and generally proper locating of a data carrying graphical symbol for subsequent imaging and data collection activities. This abstract is provided to comply with rules requiring abstracts, and is submitted with the intention that it will not be used to interpret or limit the scope and meaning of the claims.

Abstract: A self-configuring verifier for performing standardized evaluation and verification of the print quality of a data carrying graphical symbol is structured with a plurality of illumination sources and at least one imaging device. The verifier is capable of automatically determining the symbology of the graphical symbol to be evaluated, and establish a pre-defined illumination pattern and possibly other settings, as required, to satisfy pre-defined evaluation standards. Once the illumination pattern is established and setup is complete, the verifier may fully evaluate and report on the quality of at least one data carrying graphical symbol imaged by the imaging device of the verifier. This abstract is provided to comply with rules requiring an abstract, and is submitted with the intention that it will not be used to interpret or limit the scope and meaning of the claims.

Abstract: An adaptive system and a method for reading bar code symbols or the like, including a scanner for generating a light beam directed toward a target, the light beam sweeping the symbol to be read. The system further includes a photodetector for receiving reflected light from such symbol, and circuitry to determine whether the signal received is sufficiently distinct to determine that a valid symbol has been scanned, and signal processing circuitry having adjustable gain, bandwidth, and digitizer threshold characteristics for processing such signals.

Abstract: A method and apparatus to enable the high speed evaluation of the quality of a bar code indicia by processing a scan reflectance profile signal generated by a scanner unit. The scan reflectance profile signal is sampled by an analog-to-digital converter, with the sample values from the converter processed as they are produced in real-time to determine a highest positive peak sample value and a lowest negative peak sample value for each element of the bar code indicia. The lowest negative and highest positive peak sample values for each element being accessible for post-processing to determine at least one figure of merit indicative of the quality of the bar code indicia being evaluated. The samples produced by the a/d converter are processed as they are generated to filter and reduce the total collection of sample values stored and/or considered, while still providing the critical highest and lowest peak sample values for the scanned elements to enable high speed verification.

Abstract: A system for reading bar code symbols or the like, having a scanner for generating a laser beam directed toward a target and producing a first narrowly spaced apart dual line scanning pattern that enables the user to manually aim and direct the beam to the location desired by the user and a relatively wider spaced apart dual line second scanning pattern that sweeps an entire symbol to be read, and a detector for receiving reflected light from such symbol to produce electrical signals corresponding to data represented by such symbol.

Abstract: A method of manufacturing a bar code reader of the type including a scanner for generating a moving light beam directed toward a target and sweeping the bar code symbol to be read. A photodetector receives the reflected light from such symbol, and processing circuitry determines whether the signal received represents a valid symbol. The processing circuitry has adjustable gain, bandwidth, and digitizer threshold characteristics which are set during the manufacturing process.

Abstract: An arrangement for decoding a bar code symbol in which the data resulting from scanning a bar code symbol with a bar code scanner is evaluated to determine if the scanned bar code symbol is within the working range of the scanner. The data acquired by the bar code scanner is evaluated to determine if the detected widths of the bars and spaces of the scanned bar code symbol are too small, less than a threshold value, which indicates that the bar code symbol is too far and outside of the working range of the scanner. Moreover, the working range of the bar code scanner can be selectively changed by changing the threshold value, which can be easily implemented by having the bar code scanner scan a menu bar code which instructs the decoder to change the threshold value to a selected new value which may be pre-established for the particular operation.

Abstract: A system for reading bar code symbols or the like, including one- or two-dimensional bar code symbols having a scanner for generating a laser beam directed toward a target and producing a narrow first raster scanning pattern that enables the user to manually aim and direct the beam to the location desired by the user and a second raster scanning pattern that increases in height which sweeps an entire symbol to be read, and a detector for receiving reflected light from such symbol to produce electrical signals corresponding to data represented by such symbol.
