National Inventors Hall Of Fame
The National Inventors Hall of Fame (NIHF) is an American not-for-profit organization, founded in 1973, which recognizes individual engineers and inventors who hold a US patent of significant technology. Besides the Hall of Fame, it also operates a museum in Alexandria, Virginia, sponsors educational programs, and a collegiate competition. As of 2025, 652 inventors have been inducted, mostly constituting historic persons from the past three centuries, but also including living inductees. Nominees must hold a US patent of significant contribution to the US welfare, and which advances science and useful arts. History The National Inventors Hall of Fame was founded in 1973 on the initiative of H. Hume Mathews, then the chairman of the National Council of Patent Law Associations (now the National Council of Intellectual Property Law Associations). It was launched by Ed Sobey, who was also the first director. In 1974, it gained a major sponsor in the U.S. Patent and Trademar ...

American Heritage Of Invention & Technology
''Invention & Technology Magazine'' (formerly known as ''American Heritage of Invention & Technology'') is a quarterly magazine dedicated to the history of technology. It was launched with sponsorship from General Motors in the summer of 1985 as a spinoff of '' American Heritage'' magazine. Later, the magazine had a partnership with the National Inventors Hall of Fame. “Our subject matter is actually nothing less than the making of the world we live in, and the stories of all the extraordinary people who made it,” wrote Frederick Allen, the Founding Editor, in 1985. He noted that the field of the history of technology is relatively new. "Up to now there has been no general magazine of wide circulation reporting on it.

Sound Recording And Reproduction
Sound recording and reproduction is the electrical, Mechanical system, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustics, acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record (in which a stylus cuts grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to a varying magnetic field by an electromagnet, which makes a representation of the sound as magnetized areas on a plastic tape with a magnetic coating on it. Analog sound reproduction is the reverse process, with a large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
