Herman Andrew Affel
Herman Andrew Affel (August 4, 1893 – October 13, 1972) was an American electrical engineer who invented the modern coaxial cable. Biography He was born on August 4, 1893. He attended MIT. He later married Bertha May Plummer. From MIT he went to work at Bell Laboratories. Among other projects he worked with Lloyd Espenschied on the characteristics of coaxial cable. Espenschied and Affel jointly applied for a patent on a wideband coaxial cable system of transmission, filed in 1929 and granted in 1934.

American Telephone And Telegraph Company
AT&T Corporation, an abbreviation for its former name, the American Telephone and Telegraph Company, was an American telecommunications company that provided voice, video, data, and Internet telecommunications and professional services to businesses, consumers, and government agencies. During the Bell System's long history, AT&T was at times the world's largest telecommunications company, the world's largest cable television operator, and a regulated monopoly. At its peak in the 1950s and 1960s, it employed one million people and its revenue ranged between US$3 billion in 1950 ($ in present-day terms) and $12 billion in 1966 ($ in present-day terms). In 2005, AT&T was acquired by " Baby Bell" and former subsidiary SBC Communications for more than $16 billion ($ in present-day terms). SBC then changed its name to AT&T Inc., with AT&T Corporation continuing to exist as a long-distance calling subsidiary until its dissolution on May 1, 2024. History Origins ...

Nursing Home
A nursing home is a facility for the residential care of older people, senior citizens, or disabled people. Nursing homes may also be referred to as care homes, skilled nursing facilities (SNF), or long-term care facilities. Often, these terms have slightly different meanings to indicate whether the institutions are public or private, and whether they provide mostly assisted living, or nursing care and emergency medical care. Nursing homes are used by people who do not need to be in a hospital, but require care that is hard to provide in a home setting. The nursing home staff attends to the patients' medical and other needs. Most nursing homes have nursing aides and skilled nurses on hand 24 hours a day. In the United States, while nearly 1 in 10 residents aged 75 to 84 stays in a nursing home for five or more years, nearly 3 in 10 residents in that age group stay less than 100 days, the maximum duration covered by Medicare, according to the American Association for Long-Term ...

Isolationist
Isolationism is a term used to refer to a political philosophy advocating a foreign policy that opposes involvement in the political affairs, and especially the wars, of other countries. Thus, isolationism fundamentally advocates neutrality and opposes entanglement in military alliances and mutual defense pacts. In its purest form, isolationism opposes all commitments to foreign countries, including treaties and trade agreements. In the political science lexicon, there is also the term of " non-interventionism", which is sometimes improperly used to replace the concept of "isolationism". "Non-interventionism" is commonly understood as "a foreign policy of political or military non-involvement in foreign relations or in other countries' internal affairs". "Isolationism" should be interpreted more broadly as "a foreign policy grand strategy of military and political non-interference in international affairs and in the internal affairs of sovereign states, associated with trade ...

Radar Altimeter
A radar altimeter (RA), also called a radio altimeter (RALT), electronic altimeter, reflection altimeter, or low-range radio altimeter (LRRA), measures altitude above the terrain presently beneath an aircraft or spacecraft by timing how long it takes a beam of radio waves to travel to ground, reflect, and return to the craft. This type of altimeter provides the distance between the antenna and the ground directly below it, in contrast to a barometric altimeter which provides the distance above a defined vertical datum, usually mean sea level. Principle As the name implies, radar (radio detection and ranging) is the underpinning principle of the system. The system transmits radio waves down to the ground and measures the time it takes them to be reflected back up to the aircraft. The altitude above the ground is calculated from the radio waves' travel time and the speed of light. Radar altimeters required a simple system for measuring the time-of-flight that could be displayed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The IEEE was formed in 1963 as an amalgamation of the American Institute of Electrical Engineers and the Institute of Radio Engineers. History The IEEE traces its founding to 1884 and the American Institute of Electrical Engineers. In 1912, the rival Institute of Radio Engineers was formed. Although the AIEE was initially larger, the IRE attracted more students and was larger by the mid-1950s. The AIEE and IRE merged in 1963. The IEEE is headquartered in New York City, but most business is done at the IEEE Operations Center in Piscataway, New Jersey, opened in 1975.
