Driver circuit

In electronics, a driver is an electrical circuit or other electronic component used to control another circuit or component, such as a high-power transistor, liquid crystal display (LCD), and numerous others.

They are usually used to regulate current flowing through a circuit or is used to control the other factors such as other components, some devices in the circuit. The term is often used, for example, for a specialized integrated circuit that controls high-power switches in switched-mode power converters. An amplifier can also be considered a driver for loudspeakers, or a constant voltage circuit that keeps an attached component operating within a broad range of input voltages.

Typically the driver stage(s) of a circuit requires different characteristics to other circuit stages. For example in a transistor power amplifier, typically the driver circuit requires current gain, often the ability to discharge the following transistor bases rapidly, and low output impedance to avoid or minimize distortion.

Driving

Driving most often refers to the controlled operation and movement of a motorized vehicle, such as a car, truck, or bus.

Etymology

The origin of the term driver, as recorded from the 15th century, refers to the occupation of driving working animals, especially pack horses or draft horses. The verb ' to drive ' in origin means "to force to move, to impel by physical force". It is first recorded of electric railway drivers in 1889 and of a motor-car driver in 1896. Early alternatives were motorneer,motor-man, motor-driver or motorist. French favors "conducteur" (the English equivalent, "conductor", being used —from the 1830s— not of the driver but of the person in charge of passengers and collecting fares), while German influenced areas adopted Fahrer (used of coach-drivers in the 18th century, but shortened about 1900 from the compound Kraftwagenfahrer), and the verbs führen, lenken, steuern —all with a meaning "steer, guide, navigate"— translating to conduire.

Driver 76

Driver '76 is a video game for the PlayStation Portable, which was released on May 8, 2007 in the US, and on May 11, 2007 in the EU. The game is a prequel to Driver: Parallel Lines, and is set two years prior. It is the first game in the Driver series for the PSP. It was developed by Ubisoft Reflections and Sumo Digital, and published by Ubisoft.

Story

In New York City 1976, the story starts with Ray, a wheelman. He falls in love with Chen Chi, but she's already got someone, Jimmy. After gaining respect from her father, Ray is betrayed and has to earn money in the mean time. He eventually meets back with Zhou, Chen Chi's father, he tells him of how Jimmy is a traitor and for the remainder of the game you must take down Jimmy's empire. After Jimmy is presumably killed in an explosion, Zhou gives Ray his blessing to go out with Chen Chi, but finds out that she has been kidnapped by a scarred Jimmy, however Ray manages to save Chen Chi and shoot down Jimmy's helicopter with a car.

Untitled (Selections from 12)

Untitled (Selections From 12) is a 1997 promotional-only EP from German band The Notwist which was released exclusively in the United States. Though the release of the EP was primarily to promote the band's then-current album 12, it contains one track from their 1992 second record Nook as well as the non-album cover of Robert Palmer's "Johnny and Mary". The version of "Torture Day" on this EP features the vocals of Cindy Dall.

Untitled (West)

Untitled is an outdoor 1977 stainless steel sculpture by American artist Bruce West, installed in Portland, Oregon, in the United States.

Description

Bruce West's Untitled is installed along Southwest 6th Avenue between Washington and Stark streets in Portland's Transit Mall. It was one of eleven works chosen in 1977 to make the corridor "more people oriented and attractive" as part of the Portland Transit Mall Art Project. The stainless steel sculptures is 7 feet (2.1 m) tall. It was funded by TriMet and the United States Department of Transportation, and is administered by the Regional Arts & Culture Council.

Untitled (Kelly, 1975)

Untitled is an outdoor 1975 sculpture by Lee Kelly, installed at Louisa Boren Park in Seattle, Washington, in the United States. The abstract, welded Cor-Ten steel piece measures approximately 19 feet (5.8 m) x 14 feet (4.3 m) x 10 feet (3.0 m). It was surveyed and deemed "treatment needed" by the Smithsonian Institution's "Save Outdoor Sculpture!" program in November 1994. The work is part of the Seattle One Percent for Art Collection and administered by the Seattle Arts Commission.
