Raymond A. Litke
Raymond A. Litke (1920-1986) was an American electronic engineer, the inventor of a practical wireless microphone, and the first to patent the wireless microphone. He was born and raised on a farm near Alma, Kansas, but spent most of his adult life in San Jose, California. Wireless microphone Litke invented a wireless microphone in 1957 while employed as an electronics expert at San Jose State College. His supervisor challenged him to invent a microphone to use in educational presentations which would be free of wires. Litke’s wireless mike resembled a silver tube with “a microphone at the top, a transmitter in the middle and its battery power supply at the bottom.” It was 6 inches long, 1 inch in diameter, and weighed 7 ounces; the device had a broadcast range of up to a half-mile. Two types of mikes were available: lavalier and hand-held. A companion receiver, weighing 17 pounds, completed the portable sound system.Alma Signal-Enterprise. November 10, 1960. Although Litke ...

Electronic Engineering
Electronics engineering is a sub-discipline of electrical engineering which emerged in the early 20th century and is distinguished by the additional use of active components such as semiconductor devices to amplify and control electric current flow. Previously electrical engineering only used passive devices such as mechanical switches, resistors, inductors and capacitors. It covers fields such as: analog electronics, digital electronics, consumer electronics, embedded systems and power electronics. It is also involved in many related fields, for example solid-state physics, radio engineering, telecommunications, control systems, signal processing, systems engineering, computer engineering, instrumentation engineering, electric power control, robotics. The Institute of Electrical and Electronics Engineers (IEEE) is one of the most important professional bodies for electronics engineers in the US; the equivalent body in the UK is the Institution of Engineering and Te ...

Republican Party (United States)
The Republican Party, also referred to as the GOP ("Grand Old Party"), is one of the two major contemporary political parties in the United States. The GOP was founded in 1854 by anti-slavery activists who opposed the Kansas–Nebraska Act, which allowed for the potential expansion of chattel slavery into the western territories. Since Ronald Reagan's presidency in the 1980s, conservatism has been the dominant ideology of the GOP. It has been the main political rival of the Democratic Party since the mid-1850s. The Republican Party's intellectual predecessor is considered to be Northern members of the Whig Party, with Republican presidents Abraham Lincoln, Rutherford B. Hayes, Chester A. Arthur, and Benjamin Harrison all being Whigs before switching to the party, from which they were elected. The collapse of the Whigs, which had previously been one of the two major parties in the country, strengthened the party's electoral success. Upon its founding, it supported cl ...

People From Wabaunsee County, Kansas
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of p ...

Democratic Party (United States)
The Democratic Party is one of the two major contemporary political parties in the United States. Founded in 1828, it was predominantly built by Martin Van Buren, who assembled a wide cadre of politicians in every state behind war hero Andrew Jackson, making it the world's oldest active political party.M. Philip Lucas, "Martin Van Buren as Party Leader and at Andrew Jackson's Right Hand." in ''A Companion to the Antebellum Presidents 1837–1861'' (2014): 107–129."The Democratic Party, founded in 1828, is the world's oldest political party" states Its main political rival has been the Republican Party since the 1850s. The party is a big tent, and though it is often described as liberal, it is less ideologically uniform than the Republican Party (with major individuals within it frequently holding widely different political views) due to the broader list of unique voting blocs that compose it. The historical predecessor of the Democratic Party is considered to be th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wireless Microphone
A wireless microphone, or cordless microphone, is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated. Also known as a radio microphone, it has a small, battery-powered radio transmitter in the microphone body, which transmits the audio signal from the microphone by radio waves to a nearby receiver unit, which recovers the audio. The other audio equipment is connected to the receiver unit by cable. In one type the transmitter is contained within the handheld microphone body. In another type the transmitter is contained within a separate unit called a "bodypack", usually clipped to the user's belt or concealed under their clothes. The bodypack is connected by wire to a "lavalier microphone" or "lav" (a small microphone clipped to the user's lapel), a headset or earset microphone, or another wired microphone. Most bodypack designs also support a wired instrument connection (e.g., to a guitar). Wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
