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 developed ...

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 automobile is a motor vehicle with Wheel, wheels. Most definitions of ''cars'' say that they run primarily on roads, Car seat, seat one to eight people, have four wheels, and mainly transport private transport#Personal transport, people instead of cargo, goods. The year 1886 is regarded as the birth year of the car, when German inventor Carl Benz patented his Benz Patent-Motorwagen. Cars became widely available during the 20th century. One of the first cars affordable by the masses was the 1908 Ford Model T, Model T, an American car manufactured by the Ford Motor Company. Cars were rapidly adopted in the US, where they replaced Draft animal, animal-drawn carriages and carts. In Europe and other parts of the world, demand for automobiles did not increase until after World War II. The car is considered an essential part of the Developed country, developed economy. Cars have controls for driving, parking, passenger comfort, and a variety of lights. Over the decades, a ... [...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 that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of p ...

Vacuum Tube
A vacuum tube, electron tube, 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. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental electronic functions such as signal amplifier, amplification and current rectifier, rectification. Non-thermionic types such as a vacuum phototube, however, achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light intensities. In both types, the electrons are accelerated from the cathode to the anode by the electric field in the tube. The simplest vacuum tube, the diode (i.e. Fleming valve), invented in 1904 by John Ambrose Fleming, contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dynamic Range
Dynamic range (abbreviated DR, DNR, or DYR) is the ratio between the largest and smallest values that a certain quantity can assume. It is often used in the context of signals, like sound and light. It is measured either as a ratio or as a base-10 ( decibel) or base-2 (doublings, bits or stops) logarithmic value of the difference between the smallest and largest signal values. Electronically reproduced audio and video is often processed to fit the original material with a wide dynamic range into a narrower recorded dynamic range that can more easily be stored and reproduced; this processing is called dynamic range compression. Human perception The human senses of sight and hearing have a relatively high dynamic range. However, a human cannot perform these feats of perception at both extremes of the scale at the same time. The human eye takes time to adjust to different light levels, and its dynamic range in a given scene is actually quite limited due to optical glare. The ins ...

Frequency Response
In signal processing and electronics, the frequency response of a system is the quantitative measure of the magnitude and 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 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, amplifiers and loudspeakers) so that the overall response is as flat (uniform) as possible across the system's bandwidth. In control systems, such as a vehicle's cruise control, it may be used to assess system stability, often through the use of Bode plots. Systems with a specific frequency response can be designed using analog and digital filters. The frequency response characterizes systems in the frequency domain, just as the impulse response characterizes systems in the ...

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, Missouri, United States, from April 30 to December 1, 1904. Local, state, and federal funds totaling $15 million 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, art 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 plans of major cities. ...
