William S. Halstead
William Storm Halstead (1903 in Mount Kisco, NY – September 1987 in Los Angeles, CA) was an American inventor. Halstead was a prodigious inventor who held more than 80 patents involving radio and television development. As a student at Haverford College Halstead was instrumental in creating the Haverford College Radio Club, and building and launching its AM radio station WABQ in 1923. It was only the second radio station in Pennsylvania, and was described at the time as having “one of the most unusual forms of aerials ever used by a radio broadcasting station.” (''See The New York Times reference and original article from December 14, 1934, below.'') See also List of Haverford College people. In 1950, he pioneered stereophonic broadcasting. The process he developed allowed a station to use a sideband of its frequency to broadcast subsidiary programming. This process was called multiplexing, and once fully instituted removed the need for two stations, and thus two rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Engineers From New York (state)
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professional pr ...

Radio Pioneers
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
