Abstract
Abstract A code made up of wedge-shaped elements representative in binary code for character reading of information. The area covered by the wedges is equivalent to selected printed characters and the reading is accomplished by a scanner which is pulsed at precise intervals or which is dynamic in operation, i.e. continuously reading or sensing the wedge as the scanner or the code is moved in a direction from one to the other end of the wedge in either an increasing or a decreasing area thereof. The scan profiles of the wedges are indicated during continuous reading thereof or from the reading or sensing thereof at precise points therealong and such profiles are then changed into transition profiles to determine polarity of change in timing or position of the information.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
96 words
A binary data code comprising a plurality of code elements arranged in format to present adjacent areas of discernible portions corresponding to bit characters of data, each of said code elements being triangular shaped and defining widths of increasing or decreasing magnitude along the elements length in relation to a reference line, and means for reading each code element at a plurality of planes along the length thereof for identifying the corresponding bit character by sensing the change is magnitude of the widths of one code element in relation to the widths of an adjacent element.
Claim 2
Dependent Claim
96 words
A binary data code comprising a plurality of code elements arranged in format to present adjacent areas of discernible portions corresponding to bit characters of data, each of said code elements being triangular shaped and defining widths of increasing or decreasing magnitude along the elements length in relation to a reference line, and means for reading each code element at a plurality of planes along the length thereof for identifying the corresponding bit character by sensing the change is magnitude of the widths of one code element in relation to the widths of an adjacent element.
Claim 3
Dependent Claim
50 words

Claim 7
Dependent Claim
39 words
The code of claim 1 wherein said code elements are wedge-shaped and present a laterally directed edge and an inclined edge initiating in spaced relationship at said reference line and meeting at an apex distal from said reference line.
Claim 8
Dependent Claim
39 words
The code of claim 1 wherein said code elements are wedge-shaped and present a laterally directed edge and an inclined edge connecting at said reference line and initiated in spaced relationship at a base distal from said reference line.
Claim 9
Dependent Claim
37 words
The code of claim 1 wherein said code elements are oriented in one direction and said reading means scans in a direction normal to said one direction for sensing the change in magnitude of said discernible portions.
Claim 10
Dependent Claim
105 words
In a binary data code comprising a plurality of wedge-shaped code elements arranged to provide discernible areas adjacent each other and denoting character bits of information, each of said code elements defining widths of increasing or decreasing magnitude along the elements length in relation to a reference line at one side thereof, and means for reading the code elements at a plurality of planes along the length thereof by sequentially sensing the change in magnitude of the width of the discernible area of one code element in relation to the change in magnitude of the width of the discernible area of an adjacent code element.
Claim 11
Dependent Claim
105 words
In a binary data code comprising a plurality of wedge-shaped code elements arranged to provide discernible areas adjacent each other and denoting character bits of information, each of said code elements defining widths of increasing or decreasing magnitude along the elements length in relation to a reference line at one side thereof, and means for reading the code elements at a plurality of planes along the length thereof by sequentially sensing the change in magnitude of the width of the discernible area of one code element in relation to the change in magnitude of the width of the discernible area of an adjacent code element.
Claim 12
Dependent Claim
34 words
In the code of claim 9 wherein said code elements are arranged in one direction and said reading means travels in said one direction for sensing the change in ratio of said discernible areas.
Claim 13
Dependent Claim
37 words
In the code of claim 9 wherein said code elements present a laterally directed edge and an inclined edge initiating in spaced relationship at said reference line and meeting at a point distal from said reference line.
Claim 14
Dependent Claim
46 words
In the code of claim 9 wherein said code elements present a laterally directed edge and an inclined edge connected to define a point at said reference line and include an edge normal to said laterally directed edge interconnecting said inclined edge distal from said point.
