Fleming valve valve proved to be the start of a technological revolution. After reading Fleming's 1905 paper on his oscillation valve, American engineer Lee DeForest in 1906 created a three-element vacuum tube, the Audion, by adding a wire grid between cathode and anode. It was the first electronic amplifying device, allowing the creation of amplifiers and continuous wave oscillators. De Forest quickly refined his device into the triode, which became the basis of long-distance telephone and radio communications, radars, and early digital computers for 50 years, until the advent of the transistor in the 1960s. Fleming sued De Forest for infringing his
Anil K. Jain (electrical engineer, born 1946) entrepreneurs such as Brian Hinman, co-founder of PictureTel, Polycom, and 2Wire. Optivision later, after Jain's untimely death, had an initial public offering primarily thanks to the Optivision optical switching technology. Anil K. Jain (electrical engineer, born 1946) Anil K. Jain (January 21, 1946 – November 14, 1988) was an Indian-American electrical engineer and Professor of the Department of Electrical Engineering and Computer Science at the University of California, Davis, known for his contributions on "two-dimensional stochastic models for images provided a firm theoretical foundation for a number of algorithms of spectral analysis, adaptive image estimation and image data compression", including
