Abstract: An imaging scanner with a two dimensional array of sensors analyzes data from a segment of the array (115) to detect if one or more indicia conditions is present that would prevent a successful decode based on data in the segment (125) In this manner, if decoding the indicia using data from the segment of array data is not possible (130), an enlarged frame of array data (160) can be sought for decode when necessary while one-dimensional and simple two-dimensional bar codes can be quickly processed by loading and decoding only the segment of the array.

Abstract: A label (1) is applied to a product. The label (1) includes two windows (7a) and (7b) allowing a portion of the product beneath the label to be scanned with a laser. The windows (7a) and (7b) have a gap between them which is truncated. By reading the distance across the gap and the height across the gap a laser can be accurately and repeatedly aligned along the windows. A scan is taken at a point of origin for the product along the line of the windows. At a subsequent time and life of the product the scan is repeated and the repeated scan is compared to that taken at the factory to determine the authenticity of the product. The label also includes indicators (3) that locate the stored scan.

Abstract: A data reader such as for example an imaging reader with a CCD or CMOS imager or the like, having multiple images of a target item illuminated or acquired from different directions in which the image signals are combined into a complete image of the item or selected portions of the item being read such that specular reflection (over-saturated regions of the sensor array) are minimized or eliminated. In one example data reader configuration, multiple illumination sources such as first and second rows of light emitting diodes (LED's) are aimed at the item being scanned from different directions. The illumination sources are alternately pulsed and return signals are collected at one or more sensor arrays. A selected non-saturated return signal from one of the illumination sources, or selected non-saturated portions of return signal from both of the illumination sources are processed to generate a complete non-saturated image of the target. In one preferred processing scheme, assuming that each of the LED's is capable of illuminating the entire target (e.g. a barcode), a pixel-by-pixel minimum is taken of the two images thereby producing an image with specular reflection minimized or nearly eliminated.

Abstract: Novel digital optical media has recorded thereon certain symbols belonging to two classes of non-standard codes in precise predetermined locations. One class provides symbols which, when read many times by a standard optical media reader, are decoded as valid but having variable values. A second class embodies codes which are immediately recognized by the player's decoder as invalid. The first class of non-standard codes can be read by a standard optical media reader but cannot be written or reproduced by standard optical media recorders and mastering equipment, and its presence on optical media thereby serves to identify the optical media as authentic, as opposed to an unauthorized copy, which will lack these special symbols. Symbols belonging to the second class of non-standard codes serve to protect the reading of symbols belonging to the first class from being altered or stabilized by the error-correcting system of the player. Patterns combining symbols of these two classes provide a non-copyable mark for automatically verifying the authenticity of optical media and protecting the data recorded thereon from being usable except when present on authentic media.

Abstract translation: 新的数字光学介质已经在精确的预定位置记录了属于两类非标准代码的某些符号。 一类提供符号，当由标准光学介质读取器多次读取时，其被解码为有效但具有可变值。 第二类体现了玩家解码器立即识别为无效的代码。 第一类非标准代码可以由标准光学介质读取器读取，但不能由标准光学介质记录器和母盘设备进行写入或再现，因此其在光学介质上的存在可用于将光学介质识别为真实的 未经授权的复制品，将不具备这些特殊符号。 属于第二类非标准代码的符号用于保护属于第一类的符号的读取不被播放器的纠错系统改变或稳定。 组合这两个类别的符号的模式提供了用于自动验证光学介质的真实性并且保护其上记录的数据不可用的不可复制标记，除非存在于真实媒体上。
