Tennelec
Tennelec was a US electronics company founded in the early 1960s by Edward Fairstein in Oak Ridge, Tennessee. The company came to prominence producing instrumentation for nuclear studies and later, programmable scanning radios. The TC-200 amplifier was a successful early design that established Tennelec as a leader in the nuclear instrumentation field. Following on the heels of the TC-200 success, the company developed additional components necessary for precise nuclear measurement, including detectors and particle counters. Tennelec also manufactured innovative scanning radios in the 1970s. The first programmable radio scanner was the Memoryscan from Tennelec Commercial Products Division, introduced in 1974, and later known as the Memoryscan 1 (model MS-1). This was followed by a slightly improved model, the Memoryscan 2 (model MS-2). Prior to the MS-1 and MS-2, scanners were "programmed" by inserting a series of hand-cut crystals tuned for different frequencies. The scanner w ...

Scanner (radio)
A scanner (also referred to as a radio scanner) is a radio receiver that can automatically tune, or ''scan'', two or more discrete frequencies, stopping when it finds a signal on one of them and then continuing to scan other frequencies when the initial transmission ceases. The term ''scanner'' generally refers to a communications receiver that is primarily intended for monitoring VHF and UHF landmobile radio systems, as opposed to, for instance, a receiver used to monitor international shortwave transmissions. More often than not, these scanners can also tune to different types of modulation as well ( AM, FM, WFM, etc.). Early scanners were slow, bulky, and expensive. Today, modern microprocessors have enabled scanners to store thousands of channels and monitor hundreds of channels per second. Recent models can follow trunked radio systems and decode APCO-P25 digital transmissions. Both hand held and desktop models are available. Scanners are often used to monitor police, ...

Oak Ridge, Tennessee
Oak Ridge is a city in Anderson and Roane counties in the eastern part of the U.S. state of Tennessee, about west of downtown Knoxville. Oak Ridge's population was 31,402 at the 2020 census. It is part of the Knoxville Metropolitan Area. Oak Ridge's nicknames include ''the Atomic City'', ''the Secret City'', ''the Ridge'', ''the Town the Atomic Bomb Built'', and ''the City Behind the Fence''. In 1942, the United States federal government purchased nearly of farmland in the Clinch River Valley for the development of a planned city supporting 75,000 residents. It was constructed with assistance from architectural and engineering firm Skidmore, Owings & Merrill, from 1942 to 1943. Oak Ridge was established in 1942 as a production site for the Manhattan Project—the massive American, British, and Canadian operation that developed the atomic bomb. Being the site of Oak Ridge National Laboratory and Y-12 National Security Complex, scientific and technological development still pla ...

Division (business)
A division, sometimes called a business sector or business unit (segment), is one of the parts into which a business, organization or company is divided. Overview Divisions are distinct parts of a business. If these divisions are all part of the same company, then that company is legally responsible for all of the obligations and debts of the divisions. In the banking industry, an example would be East West Bancorp and its primary subsidiary, East West Bank. Legal responsibility Subsidiaries are separate, distinct legal entities for the purposes of tax A tax is a compulsory financial charge or some other type of levy imposed on a taxpayer (an individual or legal entity) by a governmental organization in order to fund government spending and various public expenditures (regional, local, or n ...ation, regulation and Legal liability, liability. For this reason, they differ from divisions, which are businesses fully integrated within the main company, and not legally ...

Binary Code
A binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system. The binary code assigns a pattern of binary digits, also known as bits, to each character, instruction, etc. For example, a binary string of eight bits (which is also called a byte) can represent any of 256 possible values and can, therefore, represent a wide variety of different items. In computing and telecommunications, binary codes are used for various methods of encoding data, such as character strings, into bit strings. Those methods may use fixed-width or variable-width strings. In a fixed-width binary code, each letter, digit, or other character is represented by a bit string of the same length; that bit string, interpreted as a binary number, is usually displayed in code tables in octal, decimal or hexadecimal notation. There are many character sets and many character encodings for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consumer Electronics Show
CES (; formerly an initialism for Consumer Electronics Show) is an annual trade show organized by the Consumer Technology Association (CTA). Held in January at the Las Vegas Convention Center in Winchester, Nevada, United States, the event typically hosts presentations of new products and technologies in the consumer electronics industry. History The first CES was held in June 1967 in New York City. It was a spinoff from the Chicago Music Show, which, until then, had served as the main event for exhibiting consumer electronics. The event had 17,500 attenders and over 100 exhibitors; the kickoff speaker was Motorola chairman Bob Galvin. From 1978 to 1994, CES was held twice each year: once in January in Las Vegas known for ''Winter Consumer Electronics Show (WCES)'' and once in June in Chicago, known as ''Summer Consumer Electronics Show (SCES)''. The winter show was successfully held in Las Vegas in 1995 as planned. However, since the summer Chicago shows were beginning to ...

Radio Shack
RadioShack, formerly RadioShack Corporation, is an American retailer founded in 1921. At its peak in 1999, RadioShack operated over 8,000 worldwide stores named RadioShack or Tandy Electronics in the United States, Mexico, United Kingdom, Australia, and Canada. Outside of those territories, the company licensed other companies to use the RadioShack brand name in parts of Asia, North Africa, Latin America, and the Caribbean.

Electronics Companies Of The United States
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small el ...
