CueCat barcode scanner and interposer cables with male and female PS/2 connectors. The CueCat, styled :CueCat with a leading colon, is a cat-shaped handheld barcode reader that was given away free to Internet users starting in 2000 by the now-defunct Digital Convergence Corporation (which often styled its own name as Digital:Convergence Corporation).
Barcode. A UPC-A barcode. A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called ...
The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [5] [6] [7] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [8] the pattern of position detection was found and determined by applying the least-used ratio (1:1:3 ...

Barcode reader. A barcode reader or barcode scanner is an optical scanner that can read printed barcodes and send the data they contain to computer. [ 1] Like a flatbed scanner, it consists of a light source, a lens, and a light sensor for translating optical impulses into electrical signals. Additionally, nearly all barcode readers contain ...
t. e. In processor design, microcode serves as an intermediary layer situated between the central processing unit (CPU) hardware and the programmer-visible instruction set architecture of a computer, also known as its machine code. [1] [page needed] It consists of a set of hardware-level instructions that implement the higher-level machine code ...
Norman Joseph Woodland (September 6, 1921 – December 9, 2012) was an American inventor and engineer, best known as one of the inventors of the barcode, for which he received a patent in October 1952. [1] [2] Later, employed by IBM, he developed the format which became the ubiquitous Universal Product Code (UPC) of product labeling and check ...
