What is "allen"

masc. proper name, variant of Alan (q.v.). In reference to wrench, key, screw, etc. with hexagonal socket or head, 1913, from the Allen Manufacturing Company of Hartford, Connecticut, U.S.

Allen, Allen's or Allens mayrefer to:

The Allen was a short-lived United States automobile manufactured in Philadelphia, Pennsylvania from 1913 to 1914.

The early models featured a two-cylinder engine, while later ones had a water-cooled four-cylinder version. These models also had a friction transmission and shaft drive, a wheelbase, and a track, costing $450.

Confusingly, another American company also offered a car called the Allen, also in 1913.

The Allen was an American automobile, built at Fostoria, Ohio between 1913 and 1921. The company used 3.1-litre side-valve Sommers four-cylinder engines, and acquired that company in 1915. The 1920 Allen 43 was a handsome craft, featuring bevel-sided touring coachwork and a high-shouldered radiator. Unfortunately, sales of this vehicle were not enough to avert the company's bankruptcy, which followed in 1921. Willys acquired what little was left. Overall, 20,00 vehicles were sold.

Confusingly, another American company also offered a car called the Allen, also in 1913, though the Ohio model was somewhat more successful.

"Allen" is the second episode of the television series Prison Break, which was first broadcast on television on August 29, 2005. The episode is the second to air alongside the Pilot episode as part of the two-part start of the series. "Allen" was written by series creator Paul Scheuring and directed by Michael Watkins. Robert Knepper makes his first appearance as Theodore "T-Bag" Bagwell, but was not yet billed as a regular character until the following episode, " Cell Test". Also, Marshall Allman, despite credited, does not appear as L. J. Burrows.

The episode's title refers to the hex key that Michael makes from a screw, the key being named "Allen Schweitzer 11121147". Also in this episode, Veronica Donovan continues her investigation as to who is actually responsible to framing Lincoln Burrows on Michael's request, while at the same time, Michael deals with the impending race riot in Fox River, which could hinder his escape plans.

Allen is a Celtic surname, originating in Scotland, and common in Ireland, Wales and England. It is a variation of the surname MacAllen and may be derived from two separate sources: Ailin, in Scottish and Irish Gaelic, means both "little rock" and "harmony", or it may also be derived from the Celtic Aluinn, which means "handsome". Variant spellings include Alan, Allan, etc. The noble family of this surname, from which a branch went to Portugal, is descended of one Alanus de Buckenhall.

In Ireland, Allen is the Anglicization of the Gaelic name Ó h-Ailín. Allen is the 41st most common surname in England.

Allen (first name and dates unknown) was an English cricketer who played for Middlesex during the 1750s and 1760s.

Allen was a robot introduced by Rodney Brooks and his team in the late 1980s, and was their first robot based on subsumption architecture. It had sonar distance and odometry on board, and used an offboard lisp machine to simulate subsumption architecture. It resembled a footstool on wheels.

Allen used three layers of control which are implemented in subsumption architecture. "The lowest layer of control makes sure that the robot does not come into contact with other objects." Due to this layer it could avoid static and dynamic obstacles, but it could not move. It sat in the middle of the room, waiting for obstruction. When the obstruction came, Allen ran away, avoiding collisions as it went. It used following internal representation, and every sonar return represented a repulsive force with, and inverse square drop off in strength. Direction of its move was obtained by sum of the repulsive forces (suitably thresholded). It possessed an additional reflex which halted it whenever it was moving forward, and something was directly in its path.

"The first level layer of control (second layer), when combined with zeroth, imbues the robot with the ability to wander around aimlessly without hitting obstacles." Owing to the second layer, Allen could randomly wander about every 10 seconds. It used simple heuristic, which was coupled with the instinct to shun barriers by vector addition. "The summed vector suppressed the more primitive obstacle avoidance vector, but the obstacle avoidance behaviour still operated, having been subsumed by the new layer, in its account of the lower level's repulsive force. Additionally, the halt reflex of the lower level operated autonomously and unchanged."

The third layer made the robot try to explore. Allen could look for distant places (with its sonars), then tried to reach them. "This layer monitored progress through odometry, generating a desired heading which suppressed the direction desired by the wander layer. The desired heading was then fed into a vector addition with the instinctive obstacle avoidance layer. The physical robot did not therefore remain true to the desires of the upper layer. The upper layer had to watch what happened in the world, through odometry, in order to understand what was really happening in the lower control layers, and send down correction signals."

Allen is a brand of hand tools, most widely known for its eponymous hex key wrenches. It is owned by Apex Tool Group.

"Allen" is the two-part season premiere of the eighth season of the animated television series Aqua Unit Patrol Squad 1 (an alternative title given to Aqua Teen Hunger Force), and the 101st and 102nd episodes of the series overall respectively. Both parts of "Allen" originally aired in the United States on May 8, 2011 and May 15, 2011 respectively on Adult Swim. In the first part Master Shake freezes himself in Dr. Weird's lab and awakes up nine years later disoriented and with no knowledge of the whereabouts of Frylock and Meatwad. In the second part Shake discovers the world is now controlled by a god-like figure named Allen who kills anyone who misbehaves in order to maintain the world as a Utopia where everyone has respect for one another.

"Allen" is the first episode of the series to be branded under an alternative title, and the first part marks the final appearance of Dr. Weird. The script for the beginning of the first part was read live by the main cast at Dragon*Con in 2010, months before the episode originally aired on television. This is the first two-part episode since " Last Last One Forever and Ever" and "Rabbot Redux", no other multi-part episodes have premiered since. Both parts later aired together back-to-back in a half-hour block on May 29, 2011. Both parts ranked #1 in their respective time slots on basic cable with all key adult demographics, and the May 29, 2011 airing was seen by 1.675 million viewers. Both parts have been made available on DVD, and other forms of home media.
