Abstract
Abstract A machine readable binary code which is dynamically variable in size, format and density of information is provided. The binary code is formed as a matrix having a perimeter and data contained therein. The perimeter is provided with density indicia for indicating the density of data contained within the matrix. The perimeter is also provided with size indicia for indicating the size of the matrix. By utilizing the density indicia and size indicia, a scanning device is able to calculate the size and information density of the binary code.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
An apparatus for generating a dynamically variable machine optically readable binary code, said apparatus comprising processing means for receiving data and in response thereto producing visual cells forming said binary code, said visual cells forming a plurality of data cells forming a matrix having a perimeter, said matrix having a variable number of data cells, said perimeter including density indicia for determining the density of data contained within the matrix, said density indicia being disposed in said perimeter independently of the positioning of said data cells contained in the matrix, said density indicia being a function of the number of data cells in said matrix, and printing means for printing said binary code.
Claim 2
Independent Claim
113 words
An apparatus for generating a dynamically variable machine optically readable binary code, said apparatus comprising processing means for receiving data and in response thereto producing visual cells forming said binary code, said visual cells forming a plurality of data cells forming a matrix having a perimeter, said matrix having a variable number of data cells, said perimeter including density indicia for determining the density of data contained within the matrix, said density indicia being disposed in said perimeter independently of the positioning of said data cells contained in the matrix, said density indicia being a function of the number of data cells in said matrix, and printing means for printing said binary code.
Claim 3
Dependent Claim
86 words
The apparatus of claim 1, wherein the density indicia means for indicating the density of the data includes a first side of the perimeter and a second side of the perimeter, each being formed of a broken line pattern formed of alternating dark areas and light areas, the product of the number of light areas and dark areas of the first side and the number of light areas and dark areas of the second side corresponding to the density of the data contained within the matrix.
Claim 4
Dependent Claim
25 words
The apparatus of claim 1, wherein the apparatus generates a perimeter which further includes size indicia means for indicating the physical size of the matrix.
Claim 5
Dependent Claim
34 words
The apparatus of claim 3, wherein the apparatus generates a perimeter which includes orientation indicia means for indicating the orientation of the matrix relative to a visual field in which said matrix is disposed.
Claim 6
Dependent Claim
26 words
The apparatus of claim 3, wherein said apparatus generates a binary code having indicia means for indicating the distribution pattern of the data within the matrix.
Claim 7
Independent Claim
87 words
An apparatus for generating a dynamically variable machine optically readable binary code said apparatus comprising processing means for receiving data and in response thereto producing visual cells forming said binary code, said visual cells representing data formed as a matrix disposed within a perimeter, said data being formed as data cells, a subset of said data cells representing a single binary character, said data cells being redundantly provided within the matrix to represent said single binary character of data and printing means for printing said binary code.
Claim 8
Independent Claim
87 words
An apparatus for generating a dynamically variable machine optically readable binary code said apparatus comprising processing means for receiving data and in response thereto producing visual cells forming said binary code, said visual cells representing data formed as a matrix disposed within a perimeter, said data being formed as data cells, a subset of said data cells representing a single binary character, said data cells being redundantly provided within the matrix to represent said single binary character of data and printing means for printing said binary code.
