[efoods]Users of the internet search engine are being greeted with a bar code in place of the usual Google logo, exactly 57 years after United States inventors Norman Woodland and Bernard Silver were granted a patent.
Woodland and Silver, who met while students at the Drexel Institute of Technology in Philadelphia, originally devised a system that would encode data in concentric circles.
The lines of varying width were developed later, partly inspired by Morse code.
