Abstract: A segmented 2D matrix symbol may be formed by dividing data into a plurality of segments, separately encoding the plurality of segments as corresponding arrays of cells, and arranging the arrays of cells in an abutting relationship. The segmented symbol may be reproduced, for example by receiving a bitmap corresponding to the formed symbol followed by printing; by copying a printed symbol; or by scanning a printed symbol and printing a copy. The reproduced symbol may be scanned, and data from only decoded segments, for example audio data, may be output.

Abstract: A method for reading and using partial data from a portable data carrier includes reading data from a portable data carrier, determining if any data is missing, and if any data is missing, restructuring the data for use, such as for running an audio decoder and expander. A method for writing data to a portable data carrier having limited capacity includes receiving a data file and optimizing at least one encoding parameter to fit at least a portion of the data file into the portable data carrier.

Abstract: Systems and methods for generating, reading and transferring identifiers are disclosed. In one embodiment, a handheld system for associating a selected audio content with an object includes an identifier applied to a surface of the object and having a predetermined graphical format that is configured to encode the selected audio content, and a handheld device operable to encode the identifier and further operable to detect an audio content associated with the identifier.

Abstract: A bar code symbol may include decode network response state configured to cause a bar code decoder to transmit a decode acknowledgement to a networked server computer corresponding to an acknowledgement address.

Abstract: A system is configured to read a prescription label and output audio information corresponding to prescription information present on or linked to the prescription label. The system may have knowledge about prescription labels and prescription information, and use this knowledge to present the audio information in a structured form to the user.

Abstract: A 2D matrix symbol may be formed by dividing data into a plurality of segments, separately encoding the plurality of segments as corresponding arrays of cells, and arranging the arrays of cells in an abutting relationship. A segmented 2D symbol may be read by capturing a plurality of images of a 2D matrix bar code symbol that is not subtended by any of the images and reconstructing at least some of the plurality of images to a portion of the 2D symbol or 2D symbol data larger than any of the images.
