Repeater

In telecommunications, a repeater is an electronic device that receives a signal and retransmits it at a higher level or higher power, or onto the other side of an obstruction, so that the signal can cover longer distances. It is a generic term that refers to several different types of devices; a telephone repeater is an amplifier in a telephone line, an optical repeater is an optoelectronic circuit that amplifies the light beam in a optical fiber cable; and a radio repeater is a radio receiver and transmitter that retransmits a radio signal. A broadcast relay station performs an analogous role 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 power in the electric current which represents the audio signal is dissipated as heat in the resistance of the copper wire. The longer the wire is, the more power is lost, and the smaller the amplitude of the signal at the far end. So with a long enough wire the call will not be audible at the other end. Similarly, the farther from a radio station a receiver is, the weaker the radio signal, and the poorer the reception. A repeater is an electronic device in a communication channel that increases the power of a signal and retransmits it, allowing it to travel further. Since it amplifies the signal, it requires a source of electric power.

Repeater (horology)

A repeater is a complication in a mechanical watch or clock that audibly chimes the hours and often minutes at the press of a button. There are many types of repeater, from the simple repeater which merely strikes the number of hours, to the minute repeater which chimes the time down to the minute, using separate tones for hours, quarter hours, and minutes. They originated before widespread artificial illumination, to allow the time to be determined in the dark, and were also used by the visually impaired. Now they are mostly valued as expensive novelties by watch and clock enthusiasts. Repeaters should not be confused with striking clocks or watches, which do not strike on demand, but merely at regular intervals.

History

The repeating clock was invented by the English cleric and inventor, the Reverend Edward Barlow in 1676. His innovation was the rack and snail striking mechanism, which could be made to repeat easily and became the standard mechanism used in both clock and watch repeaters ever since. The best kind of repeating clocks were expensive to make; a separate train of wheels had to be added to the striking mechanism, to activate it one pulled a cord whereupon it would strike the hours and quarters, or even the hours and five-minute divisions (five minutes repeating). During the nineteenth century such clocks gradually went out of use. Due to cheap imports from France, Germany and America English clockmaking went into decline and with the advent of gas lighting repeating clocks became an unnecessary luxury.

Mace

Mace is the G.I. Joe Team's undercover operative. His real name is Thomas S. Bowman, and he was first released as an action figure in 1993. Mace was born in Denver, Colorado.

His primary military specialty is undercover surveillance. His secondary military specialty is intelligence. Mace has spent years undercover, working against Cobra and other criminal factions. He feeds information to fellow "Battle Corps" members, who then make the resulting raids and arrests.

Major Altitude

Major Altitude is the G.I. Joe Team's Battle Copter pilot. His real name is Robert D. Owens, and he was born in Rumford, Rhode Island. Major Altitude was first released as an action figure in 1991, as part of the Battle Copters line. He came exclusively with the "Battle Copter" vehicle. He was released again in 1993, as part of a mail-in special called "Terrifying Lasers of Destruction". He was packaged with a Cobra agent, another helicopter pilot, called Interrogator.

Howl (2015 film)

Howl is a direct-to-video 2015 British indie monster movie, directed by Paul Hyett and starring Ed Speleers. The film is set to be released on Region 2 DVD on 26 October 2015.

Plot

Down-on-his-luck Alpha Trax train guard Joe Griffin (Ed Speleers) arrives at Waterloo Station in time to start his shift on one of the overnight passenger train, which is scheduled to depart London at midnight under a full moon. We meet the group of passengers that consist of Kate (Shauna Macdonald), Adrian (Elliot Cowan), Matthew (Amit Shah), Billy (Sam Gittens), Nina (Rosie Day), Paul (Calvin Dean) and Ged (Duncan Preston) and his wife Jenny (Ania Marson). While he checks the passengers for tickets, he meets his unrequited love, the tea-trolley girl, Ellen (Holly Weston), who consoles him for being turned down for a promotion. An hour after departure, the train is travelling through a remote and forested part of the English countryside, in a mobile communication "dead zone". Here the train is forced to undergo an emergency brake to prevent a derailment when a deer runs onto the track. The train driver Tony (Sean Pertwee) goes outside to remove the body of the deer from the undercarriage. Whilst outside, Tony gets the deer's blood on him, and is suddenly eviscerated by the creature which was stalking the deer - a howling, contorted humanoid with wolf-like legs and glowing eyes, yet disturbingly human and largely hairless.

Howl (Norwegian band)

Howl is a rock band from Oslo, Norway. The band's name is taken from the Allen Ginsberg poem with the same name.

The beginning

The band was formed in 2002 when childhood friends Lars Bendixby, Espen Blystad, Alex Engebretsen and Simen Lund started to play together while attending to the same school outside of Oslo. Through friends and acquaintances, the band came in touch with Knut Frøysnes and Kristian Syvertsen in 2004, and the band's original (and current) line-up was completed. Later the same year, the band debuted as a live act on the well known music scene Mono in Oslo. The band spent the next two years on the road, establishing a reputation as a solid live act and refining their musical expression.

Higher Class Of Lush and record deal with EMI

In 2007, Howl released their debut album Higher Class of Lush on their own label. The album was self-produced in collaboration with Frode Jacobsen from the Norwegian rock band Madrugada. The album got attention from EMI, who re-released the album in 2008. The band was one of the finalists in Årets Urørt in 2008, which is a Norwegian contest for new and upcoming bands. The singles Repeater, Nineteenseventyfive og Silver Equals Gold ended up in high rotation on several Norwegian radio stations, and was one of the most played bands on the Norwegian youth radio station NRK P3 in 2008.

Howl (Beware of Darkness EP)

Howl is the debut EP by American alt-rock band Beware of Darkness, released April 17, 2012 under exclusive license to Bright Antenna Records. The album was made available as a Digital Download, and CD available only at shows.

SPIN Magazine declared the lead single, "Howl", "[a] Zeppelin-riffing, bluesy face-stomper."
