  • Publication number: 20040094627
    Abstract: The invention relates to an optical reading system comprising an optical reader and a host processor. In one aspect of the invention, the host processor may be configured to transmit a component control instruction in response to a user input command input by a user of the host processor to remotely control the reader. The optical reader subsequently receives the transmitted component control instruction and executes the component control instruction substantially on receipt thereof. In one embodiment, execution of the component control instruction by the optical reader has the same effect as the reader trigger being manually pulled by a reader operator.

  • Publication number: 20040004128
    Abstract: The invention relates to methods and systems for analyzing and decoding image data captured with a one dimensional image sensor using N-bit mathematical methods. The analysis comprises converting a sequence of analog pixel data values to a corresponding sequence of data in an N-bit digital format and processing the data. The data can be analyzed using any or all of filtering, adaptive threshold determination, edge position interpolation, searching for distinctive barcode patterns, and detailed barcode decoding and checking. In alternative embodiments, the data is manipulated using a pre-scan of stored sequences of values. In another embodiment, the data is directly scanned and processed for qualifications, searching for, and decoding barcode patterns.
