Autococker
The Autococker is a closed-bolt semiautomatic paintball marker manufactured by Worr Game Products (WGP). It was one of the first paintball markers to be designed specifically for the sport, and has long been known throughout the paintball community for its popularity and customizability as well as its complexity. It is commonly believed that the closed-bolt design of the marker makes it inherently more accurate than its open-bolt counterparts, though this is disputed (see Accuracy, below). Once a common sight at professional paintball tournaments (especially in the early- to mid-1990s),Withstanding the Test of Time , Mohammed Alo, June 2002, The Paintball Times its popularity has since waned with the rise in popularity of [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paintball Marker
A paintball marker, also known as a paintball gun, paint gun, or simply marker, is an air gun used in the shooting sport of paintball, and the main piece of paintball equipment. Paintball markers use compressed gas, such as carbon dioxide (CO2) or compressed air (HPA), to propel dye-filled gel capsules called paintballs through the barrel and quickly strike a target. The term "marker" is derived from its original use as a tool for forestry personnel to mark trees and ranchers to mark wandering cattle. The muzzle velocity of paintball markers is approximately ; most paintball fields restrict speed to 280–300 ft/s, and small indoor fields may further restrict it down to 250 ft/s. While greater muzzle velocity is possible, it has been ruled unsafe for use on most commercial paintball fields. Marker types Paintball markers fall into two main categories in terms of mechanism – mechanical and solenoid driven electropneumatic. Mechanically operated Mechanicall ...

Electropneumatic Paintball Marker
An electropneumatic paintball marker is a paintball marker that uses a pneumatic solenoid to actuate the hammer and/or bolt's movement. History and basic operation The origin of the electropneumatic paintball marker is the subject of a patent dispute, (blocked link) but is generally acknowledged to have happened more or less simultaneously with the introduction of WDP's and PneuVenture's Shock ...

Automag (paintball Marker)
The Automag is a paintball marker designed by Tom Kaye and produced by Airgun Designs, Inc. It bears the distinction of being the first semi-automatic marker ever to win a paintball tournament. Team Swarm used Automags in their victory at the 1990 International Masters. History The first Automag was invented in 1985, but was revised several times before its release in 1990. As one of the first generation of semi-automatic paintball markers, its blow forward design was unique. Made mostly from stainless steel, the valve system was the first to incorporate a pressure regulator directly into the marker. The design also allowed for disassembly in the field without tools. The marker also introduced other innovations including a quick release twist lock barrel and the Power Feed, which was an angled feed system that prevented balls from being blown back up into the hopper. The Panther was the first prototype semi-automatic marker designed by Tom Kaye of Airgun Designs in 1988. Since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ion (paintball Marker)
The Ion is an electropneumatic paintball marker manufactured by Smart Parts. At the time of its release, the Ion was the first fully electropneumatic marker aimed at entry-level players, at a price point similar to Spyders and other mechanical blowbacks. The Ion has generally been credited with making high-rate-of-fire electropneumatic markers generally available, at a time when electropneumatic markers were considered out of reach of most casual or budget players. The original Ion was released in 2005, and soon soared in popularity, though it was often criticized for being difficult to disassemble and service. Smart Parts addressed these concerns in 2007 with the release of the Ion XE, which allows the bolt to be removed from the back of the marker. Features The Ion's receiver consists of a breech and firing chamber, both hard-anodized. Its grip frame and ASA are both made of die-cast aluminum and are powder-coated. The outer shell of the Ion is polymer. The Ion includes the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spyder Victor
The SPYDER ("Surface-to-air Python and Derby") is an Israeli short and medium range mobile air defence system developed by Rafael Advanced Defense Systems with assistance from Israel Aerospace Industries (IAI). Rafael is the prime contractor and IAI is the major subcontractor for the SPYDER program. This system achieved a notable milestone in 2005 when missiles were fired against test targets in Shdema, Israel and scored direct hits. Since then, it has been showcased in multiple military exhibitions throughout the world. The SPYDER is a low-level, quick-reaction surface-to-air missile system capable of engaging aircraft, helicopters, unmanned air vehicles, drones, cruise missiles and precision-guided munitions. It provides air defence for fixed assets and for point and area defence for mobile forces in combat areas.

Detent
A detent is a mechanical or magnetic means to resist or arrest the movement of a mechanical device. Such a device can be anything ranging from a simple metal pin to a machine. The term is also used for the method involved. Magnetic detents are most often used to divide a shaft rotation into discrete increments. Magnetic detents are inherent in some types of electric motors, most often stepper motors. Mechanics Arresting movement Ratchet and pawl The ratchet-and- pawl design arrests movements by employing a small gravity- or spring-actuated lever paired with a notched wheel. The lever is mounted on a pivot point in proximity to the wheel. The vertical angle of the sides of the notches that face the direction that rotation is desired is generally very acute (45 degrees or less), so that as the wheel rotates in that direction, the end of the lever is easily lifted or pushed out and over the top of a notch. Following this, the lever drops into the next notch and the next ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Confounding Factor
In statistics, a confounder (also confounding variable, confounding factor, extraneous determinant or lurking variable) is a variable that influences both the dependent variable and independent variable, causing a spurious association. Confounding is a causal concept, and as such, cannot be described in terms of correlations or associations.Pearl, J., (2009). Simpson's Paradox, Confounding, and Collapsibility In ''Causality: Models, Reasoning and Inference'' (2nd ed.). New York : Cambridge University Press. The existence of confounders is an important quantitative explanation why correlation does not imply causation. Confounds are threats to internal validity. Definition Confounding is defined in terms of the data generating model. Let ''X'' be some independent variable, and ''Y'' some dependent variable. To estimate the effect of ''X'' on ''Y'', the statistician must suppress the effects of extraneous variables that influence both ''X'' and ''Y''. We say that ''X'' and ...

Paintball Equipment
Paintball is an equipment-intensive sport and in order to safely conduct a game, every player requires a marker with propellant to fire the paint, a mask to protect the eyes and face, paintballs, and a loader to hold them. To ensure safety off the playing field, a barrel sock or plug for the marker is also compulsory. Depending on type of play, additional equipment can include gloves, a pack designed to comfortably carry pods containing extra paintballs, and a squeegee or swab for cleaning out the barrel in case a paintball breaks. Players may also elect to wear padding or armor in order to reduce the impact of incoming paintballs. Markers A paintball marker is the primary piece of equipment used in paintball to tag an opposing player. An expanding gas (usually carbon dioxide or high-pressure air) forces a paintball through the barrel at a muzzle velocity of approximately . This velocity is sufficient for most paintballs to break upon impact at a distance, but not so fast as t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cartridge (firearms)
A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device (primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, it is correctly used only to refer to the projectile. Cartridges can be categorized by the type of their primers – a small charge of an impact- or electric-sensitive chemical mixture that is located: at the center of the case head ( centerfire); inside the rim ( rimfire); inside the walls on the fold of the case base that is shaped like a cup (cupfire, now obsolete); in a sideways projection that is shaped like a pin ( pinfire, now obsolete); ...

Back Block Closeup Diagram
The human back, also called the dorsum, is the large posterior area of the human body, rising from the top of the buttocks to the back of the neck. It is the surface of the body opposite from the chest and the abdomen. The vertebral column runs the length of the back and creates a central area of recession. The breadth of the back is created by the shoulders at the top and the pelvis at the bottom. Back pain is a common medical condition, generally benign in origin. Structure The central feature of the human back is the vertebral column, specifically the length from the top of the thoracic vertebrae to the bottom of the lumbar vertebrae, which houses the spinal cord in its spinal canal, and which generally has some curvature that gives shape to the back. The ribcage extends from the spine at the top of the back (with the top of the ribcage corresponding to the T1 vertebra), more than halfway down the length of the back, leaving an area with less protection between the bottom o ...
