Wurlitzer Electric Piano
The Wurlitzer electronic piano is an electric piano manufactured and marketed by Wurlitzer from the mid-1950s to mid-1980s. Sound is generated by striking a metal reed with a hammer, which induces an electric current in a pickup. It is conceptually similar to the Rhodes piano, though the sound is different. The instrument was invented by Benjamin Miessner, who had worked on various types of electric pianos since the early 1930s. The first Wurlitzer was manufactured in 1954, and production continued until 1983. Originally, the piano was designed to be used in the classroom, and several dedicated teacher and student instruments were manufactured. However, it was adapted for more conventional live performances, including stage models with attachable legs and console models with built-in frames. The stage instrument was used by several popular artists, including Ray Charles, Joe Zawinul and Supertramp. Several electronic keyboards include an emulation of the Wurlitzer. As the Wu ...

Sawtooth Wave
The sawtooth wave (or saw wave) is a kind of non-sinusoidal waveform. It is so named based on its resemblance to the teeth of a plain-toothed saw with a zero rake angle. A single sawtooth, or an intermittently triggered sawtooth, is called a ramp waveform. The convention is that a sawtooth wave ramps upward and then sharply drops. In a reverse (or inverse) sawtooth wave, the wave ramps downward and then sharply rises. It can also be considered the extreme case of an asymmetric triangle wave. The equivalent piecewise linear functions x(t) = t - \lfloor t \rfloor x(t) = t \bmod 1 based on the floor function of time ''t'' is an example of a sawtooth wave with period 1. A more general form, in the range −1 to 1, and with period ''p'', is 2\left( - \left\lfloor + \right\rfloor\right) This sawtooth function has the same phase as the sine function. While a square wave is constructed from only odd harmonics, a sawtooth wave's sound is harsh and clear and its spectru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DeKalb, Illinois
DeKalb ( ) is a city in DeKalb County, Illinois, United States. The population was 43,862 according to the 2010 census, up from 39,018 at the 2000 census. The city is named after decorated Franconian-French war hero Johann de Kalb, who died during the American Revolutionary War. Founded in 1856, DeKalb became important in the development and manufacture of barbed wire, especially for agriculture and raising livestock. While agricultural-related industries remain a facet of the city, along with health and services, the city's largest employer in the 21st century is Northern Illinois University, founded in 1895.

Corinth, Mississippi
Corinth is a city in and the county seat of Alcorn County, Mississippi, United States. The population was 14,573 at the 2010 census. Its ZIP codes are 38834 and 38835. It lies on the state line with Tennessee. History Corinth was founded in 1853 as Cross City, so-called because it served as a junction for the Mobile & Ohio and Memphis & Charleston railroads. It was the town's early newspaper editor, W. E. Gibson, who suggested its current name for the city of Corinth in Greece that also served as a crossroads. Corinth's location at the junction of two railroads made it strategically important to the Confederacy during the American Civil War. Confederate General P. G. T. Beauregard retreated to Corinth after the Battle of Shiloh (April 1862), pursued by Union Major General Henry W. Halleck. General Beauregard abandoned the town on May 29 when General Halleck approached, letting it fall into the Union's hands. Since Halleck had approached so cautiously, digging entrench ...

Headphones
Headphones are a pair of small loudspeaker drivers worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear. Headphones are also known as earspeakers, earphones or, colloquially, cans. Circumaural ('around the ear') and supra-aural ('over the ear') headphones use a band over the top of the head to hold the speakers in place. Another type, known as earbuds or earpieces consist of individual units that plug into the user's ear canal. A third type are bone conduction headphones, which typically wrap around the back of the head and rest in front of the ear canal, leaving the ear canal open. In the context of telecommunication, a headset is a combination of headphone and microphone. Headphones connect to a signal source such as an au ...

Baby Grand Piano
The piano is a stringed keyboard instrument in which the strings are struck by wooden hammers that are coated with a softer material (modern hammers are covered with dense wool felt; some early pianos used leather). It is played using a keyboard, which is a row of keys (small levers) that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. It was invented in Italy by Bartolomeo Cristofori around the year 1700. Description The word "piano" is a shortened form of ''pianoforte'', the Italian term for the early 1700s versions of the instrument, which in turn derives from ''clavicembalo col piano e forte'' (key cimbalom with quiet and loud)Pollens (1995, 238) and ''fortepiano''. The Italian musical terms ''piano'' and ''forte'' indicate "soft" and "loud" respectively, in this context referring to the variations in volume (i.e., loudness) produced in response to a pianist's touch or pressure on the keys: the gre ...

Short Circuit
A short circuit (sometimes abbreviated to short or s/c) is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance. This results in an excessive current flowing through the circuit. The opposite of a short circuit is an " open circuit", which is an infinite resistance between two nodes. Definition A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion. Although usually the result of a fault, there are cases where short circuits are caused intentionally, for example, for the purpose of voltage-sensing crowbar circuit protectors. In circuit analysis, a ''short circuit'' is defined as a connection between two nodes that forces them to be at the same voltage. In an 'id ...

Metal Fatigue
In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striations on some parts of the fracture surface. The crack will continue to grow until it reaches a critical size, which occurs when the stress intensity factor of the crack exceeds the fracture toughness of the material, producing rapid propagation and typically complete fracture of the structure. Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal ''crystallising'' because of the brittle appearance of the fracture surface, but this has since been disproved. Most materials, such as composites, plastics and ceramics, seem to experience some sort of fatigue-related failure. To aid in predicting ...
