Method of representing binary data
First Claim
1. A method for graphically representing binary data in a condensed, high-density, machine-readable form, comprising the steps offorming a pattern of information-carrying graphic elements defining a geometric reference system, the reference system including a substantially continuous frame having a selected width and a plurality of synchronization lines within the frame defining boundaries of at least one data field;
- placing a plurality of machine-readable marks within the width of the frame identifying the pattern as a data-field reference system and providing information about data to be included in the system, andsubstantially filling the at least one data field with a plurality of binary data-transmission elements each characterized by the presence or absence of a machine-readable mark at each of a plurality of contiguous binary data element locations, each binary data element location having a known geometric relationship to the reference system so that coordinates of each of the plurality of individual binary data elements can be accurately determined.

Abstract
A method for graphically representing binary data in a condensed, machine-readable form, includes forming a pattern of information-carrying frame and synchronization lines defining a geometric reference system which forms boundaries of one or more data fields. The reference system carries machine-readable marks such as a bar code identifying the pattern as a data-field reference system and providing orientation and other information. The reference system also includes synchronization lines forming boundaries of each data field and providing a location reference. Within the reference system the data field has dot locations functioning as data-transmission elements. Each location has or lacks a mark, representing a "1" or "0" binary bit. Each data element location has a known geometric relationship to the synchronization lines of the reference system so that coordinates of each individual mark can be determined precisely.

8. A method of transporting binary data comprising the steps of
printing the binary data graphically on a medium in a condensed, high-density, machine-readable form by forming a plurality of first information-carrying and pattern-organization graphic elements to provide a geometric reference system from which the coordinates of each of a plurality of individual binary data element locations can be derived mathematically, and substantially filling a selected region in the reference system with a plurality of binary data-transmission elements at the locations, each element being characterized by the presence or absence of a machine-readable mark, the binary data element locations having known relationships to said first elements; -
transporting the medium; optically scanning the medium and forming a bit map of the pattern including the first and binary data elements, evaluating the first elements to determine the orientation and locations of the binary data elements, and reading the binary data elements, and wherein the step of evaluating includes tracing a frame portion of the bit-map image of the first elements to determine the orientation, tracing synchronization line portions of the bitmap image of the first elements to identify intersections of the synchronization lines, and then determining the locations of the binary data elements from the intersection locations.
