The early 20th century continued the advances of the Industrial Revolution. In The procedural loops required for mechanized textile knitting and weaving already used logic were encoded in punch-cards and tapes. Since the machines were already computers, the invention of small-scale electronics and microcontrollers did not immediately change the possible functions of these machines. In the 1960s, existing machines became outfitted with computerized numeric control (CNC) systems, enabling more accurate and efficient actuation. In 1983, Bonas Machine Company Ltd. presented the first computer-controlled, electronic, Jacquard loom. In 1988, the first US patent was awarded for a "pick and place" robot.Advancements such as these changed the nature of work for machine operators, introducing computer literacy as a skill alongside machine literacy. Advances in sensing technology and data processing of the 20th century include the spectrophotometer for color matching and automatic inspection machines.
