Relay
A relay Electromechanical relay schematic showing a control coil, four pairs of normally open and one pair of normally closed contacts An automotive-style miniature relay with the dust cover taken off A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof. Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal. Relays were first used in long-distance telegraph circuits as signal repeaters: they refresh the signal coming in from one circuit by transmitting it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations. The traditional form of a relay uses an electromagnet to c ...

Repeater
In telecommunications, a repeater is an electronic device that receives a signal and retransmits it. Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction. Some types of repeaters broadcast an identical signal, but alter its method of transmission, for example, on another frequency or baud rate. There are several different types of repeaters; a telephone repeater is an amplifier in a telephone line, an optical repeater is an optoelectronic circuit that amplifies the light beam in an optical fiber cable; and a radio repeater is a radio receiver and transmitter that retransmits a radio signal. A broadcast relay station is a repeater used in broadcast radio and television. Overview When an information-bearing signal passes through a communication channel, it is progressively degraded due to loss of power. For example, when a telephone call passes through a wire telephone line, some of the powe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relay Neuron
Interneurons (also called internuncial neurons, relay neurons, association neurons, connector neurons, intermediate neurons or local circuit neurons) are neurons that connect two brain regions, i.e. not direct motor neurons or sensory neurons. Interneurons are the central nodes of neural circuits, enabling communication between sensory or motor neurons and the central nervous system (CNS). They play vital roles in reflexes, neuronal oscillations, and neurogenesis in the adult mammalian brain. Interneurons can be further broken down into two groups: local interneurons and relay interneurons. Local interneurons have short axons and form circuits with nearby neurons to analyze small pieces of information. Relay interneurons have long axons and connect circuits of neurons in one region of the brain with those in other regions. However, interneurons are generally considered to operate mainly within local brain areas. The interaction between interneurons allow the brain to perform c ...

Relay Race
A relay race is a racing competition where members of a team take turns completing parts of Race track, racecourse or performing a certain action. Relay races take the form of professional races and amateur games. Relay races are common in running, orienteering, swimming (sport), swimming, cross-country skiing (sport), cross-country skiing, biathlon, or ice skating (usually with a baton in the fist). In the Olympic Games, there are several types of relay races that are part of track and field. Relay race, also called Relay, a track-and-field sport consisting of a set number of stages (legs), usually four, each leg run by a different member of a team. The runner finishing one leg is usually required to pass the next runner a stick-like object known as a "baton" while both are running in a marked exchange zone. In most relays, team members cover equal distances: Olympic events for both men and women are the 400-metre (4 × 100-metre) and 1,600-metre (4 × 400-metre) relays. Some non ...

Relay Bid
In contract bridge, a relay bid is a conventional bid that usually has little or no descriptive meaning but asks partner to describe some feature of his hand. A relay is often the cheapest bid available but need not be. Stayman and Blackwood are common examples of relay bids. The rationale for introducing relay bids emerged from the idea that it is not always the best use of bidding space for both partners to describe their hands. Instead, only one partner can make the cheapest bids available (relays) while the other describes his hand. This is especially useful when the asker has a balanced or very strong hand. Relay bidding systems are for the most part based on relay bids: in most sequences (especially forcing ones), one partner just relays while the other describes his hand in a highly codified manner. While relay systems offer a higher level of exchanged information than natural systems, they also have the drawbacks that they are complicated to memorize and often exclude ...

Relay (song)
"Relay" (titled "The Relay" in the United States) is a song written by Pete Townshend, the guitarist of the Who, for the band's aborted ''Lifehouse (rock opera), Lifehouse'' project. The song was also released as a moderately successful single in 1972. It was also the last non-album single by the Who until "Real Good Looking Boy", 32 years later. Background "Relay" was originally written as part of the unfinished ''Lifehouse (rock opera)#1971 version, Lifehouse'' rock opera, however, like "Join Together (The Who song), Join Together", it was not written until 1972, when Pete Townshend revisited the project, at Roger Daltrey's suggestion. In 1972, the song was resurrected to be used in ''Rock Is Dead—Long Live Rock!'', another abandoned Who album that was to be released in 1972. The song was recorded during the same sessions as "Join Together (The Who song), Join Together" and a demo of "Long Live Rock" in May 1972. "Relay" was released as a single in late 1972, backed with the K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relay (company)
GetThru, formerly Relay, is an American company that provides a peer-to-peer political text messaging platform. Daniel Souweine is a cofounder and CEO.

Relay (shop)
Relay is a chain of newspaper, magazine, book, and convenience stores, mostly based in train stations and airports. It is owned by Lagardère Travel Retail, a subsidiary of Lagardère Group. Its heaviest concentration is in France, but it also operates in other countries. In 2010, the network had 1,100 shops on 4 continents. History Relay started under the name ''Relais H, when in 1852 Louis Hachette acquired the "trainstations' libraries". The sales of newspapers quickly overperformed the sales of books. To keep books' sales up, Relais H innovated by creating book series and asking specific authors to write those series. In January 2000, the stores ''Relais H'' became ''Relay''. At that time, Relay owns 1,000 stores in 10 countries in Europe and North America. In October 2012, Lagardere TR created a joint-venture with Indian Travel Food Services to develop Relay in India. In February 2016, Lagardere sold its Travel Retail operations in Belgium to the Bpost group for $491 mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saturn Relay
The Saturn Relay is a minivan that was made by General Motors. It was introduced for the 2005 model year, and was built alongside badge engineered variants, the Buick Terraza, the Chevrolet Uplander, and the Pontiac Montana SV6 in Doraville, Georgia. The Relay was introduced with a 3.5 L LX9 V6 that generates and torque, going from 0-60 mph in the 9-second range. For 2006, a 3.9 L LZ9 V6, with 240 hp (179 kW) and 240 lb·ft (332 Nm) torque, was added as an option, which delivered faster acceleration and better response than the 3.5L engine. For 2007, the 3.5 L V6 was dropped, leaving the 3.9 L as the base engine. Consequently, the optional AWD system was also dropped, since it could not handle the torque of the 3.9 L engine. Also in 2007, the Relay received an optional flex-fuel engine but only for fleet applications. The Relay scored three "Good"s (the highest possible score) and two "acceptable"s (the second highest possible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Telecommunications Relay Service
A telecommunications relay service, also known as TRS, relay service, or IP-relay, or Web-based relay service, is an operator service that allows people who are deaf, hard of hearing, deafblind, or have a speech disorder to place calls to standard telephone users via a keyboard or assistive device. Originally, relay services were designed to be connected through a TDD, teletypewriter (TTY) or other assistive telephone device. Services gradually have expanded to include almost any real-time text capable technology such as a personal computer, laptop, mobile phone, PDA, and many other devices. The first TTY was invented by deaf scientist Robert Weitbrecht in 1964. The first relay service was established in 1974 by Converse Communications of Connecticut. Types of services available Depending on the technical and physical abilities and physical environments of users, different call types are possible via relay services.

Stage Station
A stage station or relay station, also known as a staging post, a posting station, or a stage stop, is a place where exhausted horses could be replaced by fresh animals, since a long journey was much faster without delays when horses needed rest. Stage is the space between the places known as stations or stops—known to Europeans as posts or relays. Organised long-distance land travel became known as staging or posting. Stagecoaches, post chaises, private vehicles, individual riders and the like followed the already long-established system for messengers, couriers and letter-carriers. Through metonymy the name stage also came to be used for a stagecoach alone. Posting and staging Purpose Until well into the 19th century an overland traveller anxious to reach a destination as fast as possible depended on animals. Systems of arranging a supply of fresh horses to expedite travel along a particular route had been in use at least as far back as the ancient Romans when they were ...
