  • Patent number: 8517272
    Abstract: A method includes generating a first illumination with an illumination source, and directing the first illumination to pass through an aperture to generate an illumination pattern for defining an illumination field of view that is configured to indicate a boundary surrounding the imaging field of view of the imaging system. The intensity of the first illumination changes with time. The intensity variation of the illumination pattern is perceivable by a human user. The method also includes detecting light from the barcode with the imaging sensor to create imaging data while the barcode is illuminated by a second illumination, and processing the imaging data to decode an image of the barcode.

  • Patent number: 6125072
    Abstract: A memory system and a manner of operating the memory system are provided. The memory system includes several arrays arranged in groups of columns having a column address, and rows having a row address. Operating the system involves storing blocks of data in the arrays in a way that provides contiguous logical addresses for the blocks of data. A block of data is stored in a row of a group of columns in an array. The row address is incremented and the process repeated until a row limit is reached. Next, the process is repeated with another array until blocks of data have been stored in all rows of a corresponding group of columns in the array. The column address is incremented and the row address reset, and the process repeated until a column limit is reached.
