Taser (dinghy)
A taser is a conducted energy device (CED) primarily used to incapacitate people, allowing them to be approached and handled in an unresisting and thus safe manner. Sold by Axon, formerly TASER International, the device fires two small barbed darts intended to puncture the skin and remain attached to the target, at . Their range extends from for non-Law Enforcement Tasers to for Law Enforcement Tasers. The darts are connected to the main unit by thin insulated copper wire and deliver a modulated electric current designed to disrupt voluntary control of muscles, causing "neuromuscular incapacitation." The effects of a taser may only be localized pain or strong involuntary long muscle contractions, based on the mode of use and connectivity of the darts. Tasers are marketed as less-lethal, since the possibility of serious injury or death exists whenever the weapon is deployed. In the US, at least 49 people died in 2018 after being shocked by police with a Taser. The f ...

Jack Cover
John Higson Cover Jr. (April 6, 1920 – February 7, 2009) was an American aerospace scientist who was the inventor of the Taser stun gun. Biography Cover was born in New York City on April 6, 1920, and grew up in Chicago. His father was a professor of economics. His mother earned a mathematics master's degree at the University of Chicago. Cover earned a bachelor's degree and a doctorate in nuclear physics at the same university, studying under Enrico Fermi.Cover's obituary, Time Magazine, early 2009 (before March) During World War II, he was an Army Air Force test pilot. He later worked at the Naval Air Weapons Station China Lake. He was a scientist at North American Aviation from 1952 until 1964 and also worked for NASA (Apollo program), IBM and Hughes Aircraft. In 1970, he formed Taser Systems, Inc., named for a Tom Swift novel about the Thomas A. Swift's Electric Rifle. Because the Taser used gunpowder to launch the darts, the federal government considered it a fire ...

Handgun
A handgun is a short- barrelled gun, typically a firearm, that is designed to be usable with only one hand. It is distinguished from a long gun (i.e. rifle, shotgun or machine gun, etc.), which needs to be held by both hands and also braced against the shoulder to be used properly. The two most common types of handguns in modern times are revolvers and semi-automatic pistols, although other types such as derringers and machine pistols also see infrequent usage. Before commercial mass production, handguns were often considered a badge of office, comparable to a ceremonial sword. As they had limited utility and were more expensive than the long guns of the era, the few who could only afford to purchase them carried these handguns. However, in 1836, Samuel Colt patented the Colt Paterson, the first practical mass-produced revolver, which was capable of firing five shots in rapid succession and very quickly became a popular defensive weapon, giving rise to the saying, ...

Felon
A felony is traditionally considered a crime of high seriousness, whereas a misdemeanor is regarded as less serious. The term "felony" originated from English common law (from the French medieval word "félonie") to describe an offense that resulted in the confiscation of a convicted person's land and goods, to which additional punishments including capital punishment could be added; other crimes were called misdemeanors. Following conviction of a felony in a court of law, a person may be described as a felon or a convicted felon. Some common law countries and jurisdictions no longer classify crimes as felonies or misdemeanors and instead use other distinctions, such as by classifying serious crimes as indictable offences and less serious crimes as summary offences. In the United States, where the felony/misdemeanor distinction is still widely applied, the federal government defines a felony as a crime punishable by death or imprisonment in excess of one year. If punishable by ...

Bureau Of Alcohol, Tobacco And Firearms
The Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE), commonly referred to as the ATF, is a domestic law enforcement agency within the United States Department of Justice. Its responsibilities include the investigation and prevention of federal offenses involving the unlawful use, manufacture, and possession of firearms and explosives; acts of arson and bombings; and illegal trafficking and tax evasion of alcohol and tobacco products. The ATF also regulates via licensing the sale, possession, and transportation of firearms, ammunition, and explosives in interstate commerce. Many of the ATF's activities are carried out in conjunction with task forces made up of state and local law enforcement officers, such as Project Safe Neighborhoods. The ATF operates a unique fire research laboratory in Beltsville, Maryland, where full-scale mock-ups of criminal arson can be reconstructed. The ATF had 5,285 employees and an annual budget of almost $1.5 billion in 2021. The ...

Smokeless Powder
Finnish smokeless powderSmokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to gunpowder ("black powder"). The combustion products are mainly gaseous, compared to around 55% solid products (mostly potassium carbonate, potassium sulfate, and potassium sulfide) for black powder. In addition, smokeless powder does not leave the thick, heavy fouling of hygroscopic material associated with black powder that causes rusting of the barrel. Despite its name, smokeless powder is not completely free of smoke; while there may be little noticeable smoke from small-arms ammunition, smoke from artillery fire can be substantial. Originally invented in 1884 by Paul Vieille, the most common formulations are based on nitrocellulose, but the term was also used to describe various picrate mixtures with nitrate, chlorate, or dichromate oxidizers during the late 19th century, before the advantages of nitrocellu ...

Laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light which is coherence (physics), ''coherent''. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and Photolithography#Light sources, lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimated light, collimation), enabling applications such as laser pointers and lidar (light detection and ranging). Lasers can also have high temporal coherence, which allows them to emit light with a very narrow frequency spectrum, spectru ...

Tom Swift
Tom Swift is the main character of six series of American juvenile science fiction and adventure novels that emphasize science, invention, and technology. First published in 1910, the series totals more than 100 volumes. The character was created by Edward Stratemeyer, the founder of the Stratemeyer Syndicate, a book packaging firm. Tom's adventures have been written by various ghostwriters, beginning with Howard Garis. Most of the books are credited to the collective pseudonym " Victor Appleton". The 33 volumes of the second series use the pseudonym Victor Appleton II for the author. For this series, and some of the later series, the main character is " Tom Swift Jr." New titles have been published as recently as 2007. Most of the various series emphasized Tom's inventions. The books generally describe the effects of science and technology as wholly beneficial, and the role of the inventor in society as admirable and heroic. Translated into many languages, the books h ...
