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 infringement, patent dispute, (blocked link) but is generally acknowledged to have happened more or less simultaneously with the introduction of WDP (company), WDP's Angel (paintball), Angel and PneuVenture's Shocker, marketed by Smart Parts, both in 1996. The markers were operated differently; they were similar only to the extent that they both make use of one or more microswitch-controlled solenoid valves. The Shocker used two solenoid-operated control valves in order to obtain separate con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angel (Paintball Gun) 1
An angel is a Spirit (supernatural entity), spiritual (without a physical body), heaven, heavenly, or supernatural being, usually humanoid with Bird wing, bird-like wings, often depicted as a messenger or intermediary between God (the Transcendence (religion), transcendent) and humanity (the Profane (religion), profane) in various traditions like the Abrahamic religions. Other roles include protectors and guides for humans, such as guardian angels and servants of God. In Western religions, Western belief-systems the term is often used to distinguish Good and evil, benevolent from malevolent intermediary beings. Emphasizing the distance between God and mankind, Revelation, revelation-based belief-systems require angels to bridge the gap between the earthly and the transcendent realm. Angels play a lesser role in Monism, monistic belief-systems, since the gap is non-existent. However, angelic beings might be conceived as aid to achieve a proper relationship with the divine. Ab ...

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 Paintball equipment#Paintballs, 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.

Solenoid
upright=1.20, An illustration of a solenoid upright=1.20, Magnetic field created by a seven-loop solenoid (cross-sectional view) described using field lines A solenoid () is a type of electromagnet formed by a helix, helical coil of wire whose length is substantially greater than its diameter, which generates a controlled magnetic field. The coil can produce a uniform magnetic field in a volume of space when an electric current is passed through it. André-Marie Ampère coined the term ''solenoid'' in 1823, having conceived of the device in 1820. The French term originally created by Ampère is ''solénoïde'', which is a French transliteration of the Greek word '' σωληνοειδὴς'' which means ''tubular''. The helical coil of a solenoid does not necessarily need to revolve around a straight-line axis; for example, William Sturgeon's electromagnet of 1824 consisted of a solenoid bent into a horseshoe shape (similarly to an arc spring). Solenoids provide magnetic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent Infringement
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mu ...

Angel (paintball)
The Angel is one of the first electropneumatic paintball markers. It was manufactured by Angel Paintball Sports (originally WDP) starting in 1997 and was introduced alongside Smart Parts' original Shocker. The Angel was initially distributed in the United States by Brass Eagle as the ''1455 Angel Semi-auto'', advertised with a rate of 15 balls per second. This deal was short-lived, so WDP then distributed the Angel independently; refining the marker and releasing new models. History The Angel paintball marker was designed by engineer John Rice, as an ''HPA-only'' marker. Despite its ubiquitous use in the sport at the time, Rice considered CO2 a ''dirty gas'', so the Angel used miniaturized components that could not withstand impurities in the air or the cooling effects of CO2. To cater to the sudden need for a high-flow HPA regulator, WDP released the ''Gov'nair high pressure air'' system. The marker featured an electronic firing sequence and light trigger for effective ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smart Parts
Smart Parts was a paintball manufacturing company in Latrobe, Pennsylvania, which filed for liquidation on July 28, 2010. As of August 22, 2010 Smart Parts' assets and intellectual property were acquired by Kee Action Sports. Products Smart Parts was a producer of paintball markers and accessories. Their first product was the Smart Parts aluminium one-piece barrel made for the Tippmann 68 Special and the PMI-3 semi automatic markers. This barrel had a standard bore with a spiral drilled venting system in the end of the barrel. The design supposedly improved accuracy by decreasing turbulence as the paintball exited the barrel, and also decreased noise produced by the gun upon firing. The later All-American Barrel was a two-piece barrel system using spiral porting and a front bore diameter of 68 caliber. In the early to mid-1990s Smart Parts' products ranged from barrels and clothing to a few generic accessories along with some marker specific ones (such as parts for the AirGun ...

Solenoid Valve
A solenoid valve is an electromechanically operated valve. Solenoid valves differ in the characteristics of the electric current they use, the strength of the magnetic field they generate, the mechanism they use to regulate the fluid, and the type and characteristics of fluid they control. The mechanism varies from linear action, plunger-type actuators to pivoted-armature actuators and rocker actuators. The valve can use a two-port design to regulate a flow or use a three or more port design to switch flows between ports. Multiple solenoid valves can be placed together on a manifold. Solenoid valves are the most frequently used control elements in fluidics. Their tasks are to shut off, release, dose, distribute or mix fluids. They are found in many application areas. Solenoids offer fast and safe switching, high-reliability, long service life, good medium compatibility of the materials used, low control power and compact design. Operation There are many valve design varia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, 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 Electropneumatic paintball marker, electropneumatic markers.

Stock Paintball
Paintball is played with a potentially limitless variety of rules and variations, all of which are specified before the game begins. The most basic of all game rules is that players must attempt to accomplish a goal without being tagged with paintballs. Generally paintball is divided into either its original incarnation woodsball, or the small arena-based and tournament de facto speedball. Amongst these paintball game types, variations of basic rules can be played. Stock paintball Stock Paintball is based on the original technology of the 1980s. A player uses a pump action paintball marker, which requires a pumping movement after each shot to reload, and must adhere to the following rules: * The marker must have a horizontal paintball feed - the marker must be tilted (rocked) forward or backward to feed the next shot. * The marker may not be semi-automatic - it requires pumping or cocking prior to each shot being fired (in other words "rock and cock"). * The marker must be powere ...

Piezoelectric
Piezoelectricity (, ) is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in response to applied stress (mechanics), mechanical stress. The piezoelectric effect results from the linear electromechanical interaction between the mechanical and electrical states in crystalline materials with no centrosymmetry, inversion symmetry. The piezoelectric effect is a reversible process (thermodynamics), reversible process: List of piezoelectric materials, materials exhibiting the piezoelectric effect also exhibit the reverse piezoelectric effect, the internal generation of a mechanical strain resulting from an applied electric field. For example, lead zirconate titanate crystals will generate measurable piezoelectricity when their static structure is Deformation (physics), deformed by about 0.1% of the original dimension. Conversely, those same crystals will change about 0.1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
