I2/5 on a 135 film can; part of DX encoding. On 135 film (35 mm) canisters, interleaved 2 of 5 is used to identify the manufacturer, the film type, number of exposures and proprietary information using 6 digits. The barcode is located between the electrically read silver and black DX Camera Auto-Sensing Code and the film can exit lip. It is ...
Punched tape with the word "Wikipedia" encoded in ASCII.Presence and absence of a hole represents 1 and 0, respectively; for example, W is encoded as 1010111.. Character encoding is the process of assigning numbers to graphical characters, especially the written characters of human language, allowing them to be stored, transmitted, and transformed using computers.

An example with IOB format: Alex I-PER is O going O to O Los I-LOC Angeles I-LOC in O California I-LOC. Notice how "Alex", "Los" and "California", although first tokens of their chunk, have the "I-" prefix. The same example after filtering out stop words: Alex I-PER going O Los I-LOC Angeles I-LOC California B-LOC
The code is used in the pharmaceutical industry and has an advantage that it can be applied to products and materials in a wide variety of ways, including printed labels, ink-jet printing, laser-etching, indenting or hole punching.

A Swiss postal barcode encoding "RI 476 394 652 CH" in Code 128 (B & C) Code 128 is a high-density linear barcode symbology defined in ISO/IEC 15417:2007. [1] It is used for alphanumeric or numeric-only barcodes. It can encode all 128 characters of ASCII and, by use of an extension symbol (FNC4), the Latin-1 characters defined in ISO/IEC 8859-1.
This encoding guarantees that the first group always starts with an L-code, which has odd parity, and that the second group always starts with an R-code, which has even parity. Thus, it does not matter whether the barcode is scanned from the left or from the right, as the scanning software can use this parity to identify the start and end of ...
For example, Universal Product Code (UPC) barcodes are very difficult to read for humans, but very effective and reliable with the proper equipment, whereas the strings of numerals that commonly accompany the label are the human-readable form of the barcode information. Since any type of data encoding can be parsed by a suitably programmed ...
When encoding the (+10 to +30) letters the equation needs a "−1" added so 'A' is WNNNW → 1 + 10 − 1 → 10 as shown in the table. The last four characters consist of all narrow bars and three wide spaces. There are four possible positions for the single narrow space. This table outlines the Code 39 specification.
