Abstract

DOTEM is an information-coding method which is used to represent same on physical media with the aid of dots and in a computerised format, in memory and on networks with bits. The method is based on the broad concept of characters grouped into alphabets. The characters comprise dots on documents, for example, and bits in machine format. The physical characters have specific dots that are not represented in machine format in order to enable same to be located on media, such as the foot of a character and the head of a character. Each character can represent at least the 256 values of an octet. The character concept is extended such that it can be identified by the value thereof and, such that it can be identified by the value thereof and, taken together, can represent one or more variables having any dimension but determined in the structure of the character. The complex data and the context thereof can be described by a series of characters in the form of words or even sentences with a direct language correspondence. As a result, the representation is simpler and more concise. The characters are constructed over several columns for documents and over several octets for machine format. The characters can code values far greater than the octet, such that tags or field delimiters can be designated directly without the need for prior formatting.

Claims

1. A method of processing information, comprising at least a coding operation including digitally coding such information, and a printing operation including printing the resulting coded digital information on a physical medium in the form of characters designed for subsequent machine-reading, each character including a bi-dimensional arrangement of dots, each dot having at least one color among a plurality of at least two colours, and each character extending on at least two columns and comprising at least a header, data, and up/down orientation marks, wherein the coding operation further comprises, for each character, the operation of choosing a number of columns as a function of digital information to be coded, and that the printing operation further comprises, for each character, the operation of printing, in a predetermined position of each column from the second column, at least one dot indicating whether such column is, or not, the last column of such character, wherein the width of each character is automatically adjusted, both during printing and machine-reading, as a function of the coded digital information without loss of space.

2. The method of processing information according to claim 1, further comprising a preliminary operation including defining a plurality of character fonts and in assigning a dedicated digital code to each font of the plurality of character fonts, in that the coding operation further comprises, for each character, the operation of choosing a specific font among said plurality of fonts, and in that the printing operation further comprises, for each character, the operation of printing, in a predetermined position of the character, at least one dot coding the specific font, wherein the representation power of each character is extended.

3. The method of processing information according to claim 2, wherein the header comprises an alternating succession of black dots and mixed dots, mixed dots comprising a half black dot and a half white dot, or an absence of black dots in order to form a crenellated line.

4. The method of processing information according to claim 3, wherein the printed character comprises two columns and a group of predetermined dots as:

2 dots reserved for the extension of the coding of the value coded by the value column;

1 dot characterising the parity of the number of its own black dots;

1 dot for the parity of the number of black dots in the value column;

1 dot specifies the parity of the number of segments formed from black dots in the value column;

1 dot gives the state of the first dot in the value column; and

1 dot indicating whether the present column is the last of the character or whether the following control/extension column also forms part of it.

5. The method of processing information according to claim 3, wherein the first column of the structure of physical characters has a mixed last dot formed from a white half dot and a black half dot.

6. The method of processing information according to claim 3, wherein the third column of the characters of 3-column definition comprises:

1 dot characterising the parity of the number of its black dots;

1 dot indicating whether the present column is the last of the character or whether the following control/extension column also forms part of this character;

1 dot expressing the linking of the properties or independence with the following control/extension column;

1 dot specifies the parity of the number of segments of black dots of the previous control/extension column;

4 dots reserved for the extension of the coding of the value coded by the previous columns; and

the first two columns are identical to those of the characters defined on 2 columns.

7. The method of processing information according to claim 3, wherein the characters with a definition greater than three columns can be composed beyond the third by a succession of columns produced according to the same coding rules as column 3.

8. The method of processing information according to claim 2, wherein three predetermined dots define a specific font, wherein the representation power of each character is extended.
