Miller Reese Hutchison
Miller Reese Hutchison (August 6, 1876 – February 16, 1944) was an American electrical engineer and inventor. He developed some of the first portable electric devices, such as a vehicle horn and a hearing aid. His father was William Hutchison and mother born Tracie Elizabeth Magruder. He attended Marion Military Institute from 1889 through 1891, Spring Hill College 1891 through 1892, the University of Mobile Military Institute from 1892 through 1895, and graduated from Auburn University (then called Alabama Polytechnical Institute) in 1897. While still in school he invented and patented a lightning arrester for telegraph lines in 1895. At the outbreak of the Spanish–American War in 1898, he volunteered and was appointed engineer for the United States Lighthouse Board, laying cables and mines to protect harbors in the Gulf of Mexico. Hearing aids Hutchison assembled an electrical hearing aid for one of his friends; it was called the "akouphone" when it was first develop ...

Acousticon - 1906 Hearing Aid
''Acousticon Hour'' was a "musicale" radio program aired during 1927 and 1928 on NBC. It offered selections from classical music, orchestral favorites, operas and operettas. History The show was sponsored by the company that marketed the Acousticon brand hearing aid, invented by Miller Reese Hutchison. As broadcast historian Elizabeth McLeod has noted, in the 1920s a product name used in a show's title was considered a more acceptable form of advertising than the use of intrusive commercial messages: :The most popular program format of the late twenties was the sponsored musical feature. It could be a large symphonic group, a dance orchestra, or a song-and-patter team — and it would usually carry the sponsor's name. The A&P Gypsies, for example — a large, genre-crossing orchestra conducted by Harry Horlick. The Ipana Troubadors — a hot dance band directed by Sam Lanin. The Goodrich Zippers — a banjo-driven orchestra conducted by Harry Reser, when he wasn't leading th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automobile
A car, or an automobile, is a motor vehicle with wheels. Most definitions of cars state that they run primarily on roads, Car seat, seat one to eight people, have four wheels, and mainly transport private transport#Personal transport, people rather than cargo. There are around one billion cars in use worldwide. The French inventor Nicolas-Joseph Cugnot built the first steam-powered road vehicle in 1769, while the Swiss inventor François Isaac de Rivaz designed and constructed the first internal combustion-powered automobile in 1808. The modern car—a practical, marketable automobile for everyday use—was invented in 1886, when the German inventor Carl Benz patented his Benz Patent-Motorwagen. Commercial cars became widely available during the 20th century. The 1901 Oldsmobile Curved Dash and the 1908 Ford Model T, both American cars, are widely considered the first mass-produced and mass-affordable cars, respectively. Cars were rapidly adopted in the US, where they replac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Klaxon Horn, 1910
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing with electrical c ...

Vacuum Tube
A vacuum tube, electron tube, thermionic valve (British usage), or tube (North America) is a device that controls electric current flow in a high vacuum between electrodes to which an electric voltage, potential difference has been applied. It takes the form of an evacuated tubular envelope of glass or sometimes metal containing electrodes connected to external connection pins. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental Electronics, electronic functions such as signal amplifier, amplification and current Rectifier, rectification. Non-thermionic types such as vacuum phototubes achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light and measurement of its intensity. In both types the electrons are accelerated from the cathode to the anode by the electric field in the tube. The first, and simplest, vacuum tube, the diode or Flem ...

Frequency Response
In signal processing and electronics, the frequency response of a system is the quantitative measure of the magnitude and Phase (waves), phase of the output as a function of input frequency. The frequency response is widely used in the design and analysis of systems, such as audio system, audio and control systems, where they simplify mathematical analysis by converting governing differential equations into algebraic equations. In an audio system, it may be used to minimize audible distortion by designing components (such as microphones, Audio power amplifier, amplifiers and loudspeakers) so that the overall response is as flat (uniform) as possible across the system's Bandwidth (signal processing), bandwidth. In control systems, such as a vehicle's cruise control, it may be used to assess system Stability theory, stability, often through the use of Bode plots. Systems with a specific frequency response can be designed using analog filter, analog and digital filters. The frequency ...

Louisiana Purchase Exposition
The Louisiana Purchase Exposition, informally known as the St. Louis World's Fair, was an World's fair, international exposition held in St. Louis, St. Louis, Missouri, United States, from April 30 to December 1, 1904. Local, state, and federal funds totaling $15 million (equivalent to $ in ) were used to finance the event. More than 60 countries and 43 of the then-45 American states maintained exhibition spaces at the fair, which was attended by nearly 19.7 million people. Historians generally emphasize the prominence of the themes of Race (human categorization), race and imperialism, and the fair's long-lasting impact on intellectuals in the fields of history, architecture, and anthropology. From the point of view of the memory of the average person who attended the fair, it primarily promoted entertainment, consumer goods, and popular culture. The monumental Greco-Roman architecture of this and other fairs of the era did much to influence permanent new buildings and master p ...

Suzanne Adams
Suzanne Adams (28 November 1872 – 5 February 1953) was an American lyric coloratura soprano. Known for her agile and pure voice, Adams first became well known in France before establishing herself as one of the Metropolitan Opera's leading sopranos at the beginning of the twentieth century. Biography Adams was born in Cambridge, Massachusetts on November 28, 1872, the daughter of John Gedney Adams. She studied in Manhattan, New York City with Jacques Bouhy and then in Paris with Mathilde Marchesi. She made her début at the Paris Opéra in 1894 or 1895 in Charles Gounod's ''Roméo et Juliette''. She studied the roles of Juliette and Marguerite from ''Faust'' with Gounod himself, who greatly admired her fine technique, brilliant tone, and vocal flexibility. Adams remained at the Paris Opera for three years and then went to Nice. While in France, she sang numerous roles by Gounod and Meyerbeer, as well as the Queen of the Night in Mozart's ''The Magic Flute'' and the title role ...
