Electrical engineering. Aerospace engineering. Computer science. Dr. Lawrence Jerome Fogel (March 2, 1928 – February 18, 2007) was a pioneer in evolutionary computation and human factors analysis. He is known as the inventor of active noise cancellation and the father of evolutionary programming.
Active noise control ( ANC ), also known as noise cancellation ( NC ), or active noise reduction ( ANR ), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first. The concept was first developed in the late 1930s; later developmental work that began in the 1950s eventually resulted in ...
Noise -cancelling headphones alongside a carry case. Noise-cancelling headphones are headphones which suppress unwanted ambient sounds using active noise control. This is distinct from passive headphones which, if they reduce ambient sounds at all, use techniques such as soundproofing . Noise cancellation makes it possible to listen to audio ...
Platt's roving frame, c. 1858. Cotton-spinning machinery is machines which process (or spin) prepared cotton roving into workable yarn or thread. [ 1] Such machinery can be dated back centuries. During the 18th and 19th centuries, as part of the Industrial Revolution cotton-spinning machinery was developed to bring mass production to the cotton ...
Spinning jenny. Model of spinning jenny in the Museum of Early Industrialisation, Wuppertal, Germany. The spinning jenny is a multi- spindle spinning frame, and was one of the key developments in the industrialisation of textile manufacturing during the early Industrial Revolution. It was invented in 1764–1765 by James Hargreaves in Stan hill ...
A power loom is a mechanized loom, and was one of the key developments in the industrialization of weaving during the early Industrial Revolution. The first power loom was designed and patented in 1785 by Edmund Cartwright. [1] It was refined over the next 47 years until a design by the Howard and Bullough company made the operation completely ...
Sir Richard Arkwright (23 December 1732 – 3 August 1792) was an English inventor and a leading entrepreneur during the early Industrial Revolution.He is credited as the driving force behind the development of the spinning frame, known as the water frame after it was adapted to use water power; and he patented a rotary carding engine to convert raw cotton to 'cotton lap' prior to spinning.
Mary Walton. Mary Elizabeth Walton was a nineteenth-century American inventor who was awarded two patents for pollution-reducing devices. In 1881, Walton created a method for reducing the environmental hazards of the smoke emitted from locomotive, industrial and residential chimneys. Her system deflected the emissions being produced by factory ...
