Full Body Scanner
A full-body scanner is a device that detects objects on or inside a person's body for security screening purposes, without physically removing clothes or making physical contact. Unlike metal detectors, full-body scanners can detect non-metal objects, which became an increasing concern after various airliner bombing attempts in the 2000s and some scanners can also detect swallowed items or hidden in body cavities of a person. Starting in 2007, full-body scanners started supplementing metal detectors at airports and train stations in many countries. Three distinct technologies have been used in practice: * ''Millimeter wave scanners'' use non-ionizing electromagnetic radiation similar to that used by wireless data transmitters, in the extremely high frequency (EHF) radio band (which is a lower frequency than visible light). The health risks posed by these machines are still being studied, and the evidence is mixed, though millimeter wave scanners do not generate ionizing radia ...

Heat Radiation
Thermal radiation is electromagnetic radiation generated by the thermal motion of particles in matter. Thermal radiation is generated when heat from the movement of charges in the material (electrons and protons in common forms of matter) is converted to electromagnetic radiation. All matter with a temperature greater than absolute zero emits thermal radiation. At room temperature, most of the emission is in the infrared (IR) spectrum. Particle motion results in charge-acceleration or dipole oscillation which produces electromagnetic radiation. Infrared radiation emitted by animals (detectable with an infrared camera) and cosmic microwave background radiation are examples of thermal radiation. If a radiation object meets the physical characteristics of a black body in thermodynamic equilibrium, the radiation is called blackbody radiation. Planck's law describes the spectrum of blackbody radiation, which depends solely on the object's temperature. Wien's displacement law de ...

Child Pornography
Child pornography (also called CP, child sexual abuse material, CSAM, child porn, or kiddie porn) is pornography that unlawfully exploits children for sexual stimulation. It may be produced with the direct involvement or sexual assault of a child (also known as child sexual abuse images) or it may be simulated child pornography. Abuse of the child occurs during the sexual acts or lascivious exhibitions of genitals or pubic areas which are recorded in the production of child pornography. Child pornography may use a variety of mediums, including writings, magazines, photos, sculpture, drawing, painting, animation, sound recording, video, and video games. Child pornography may be created for profit or other reasons. Laws regarding child pornography generally include sexual images involving prepubescents, pubescent, or post-pubescent minors and computer-generated images that appear to involve them. Most possessors of child pornography who are arrested are found to possess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of United States Federal Prisons
The Federal Bureau of Prisons classifies prisons into seven categories: * United States penitentiaries * Federal correctional institutions * Private correctional institutions * Federal prison camps * Administrative facilities * Federal correctional complexes *Former Federal facilities This list does not include military prisons, halfway houses, or prisons, jails, and other facilities operated by state or local governments that contract with the Federal Bureau of Prisons. It also does not include facilities operated by Immigration and Customs Enforcement (ICE). United States penitentiaries Most United States penitentiaries (USPs) are high-security facilities, which have highly secured perimeters with walls or reinforced fences, multiple and single-occupant cell housing, the highest staff-to-inmate ratio, and close control of inmate movement. The most restrictive facility in the federal prison system is USP Florence ADMAX, the federal supermax prison, which holds inmates who a ...

Homeland Security
Homeland security is an American national security term for "the national effort to ensure a homeland that is safe, secure, and resilient against terrorism and other hazards where American interests, aspirations, and ways of life can thrive" to the "national effort to prevent terrorist attacks within the United States, reduce the vulnerability of the U.S. to terrorism, and minimize the damage from attacks that do occur." According to an official work published by the Congressional Research Service in 2013, the "Homeland security" term's definition has varied over time. Homeland security is not constrained to terrorist incidents. Terrorism is violent, criminal acts committed by individuals and/or groups to further ideological goals stemming from influences, such as those of a political, religious, social, racial, or environmental nature. Within the US, an all-hazards approach exists regarding homeland security endeavors. In this sense, homeland security encompasses both natural ...

Transportation Security Administration
The Transportation Security Administration (TSA) is an agency of the United States Department of Homeland Security (DHS) that has authority over the security of transportation systems within, and connecting to the United States. It was created as a response to the September 11 attacks to improve airport security procedures and consolidate air travel security under a dedicated federal administrative law enforcement agency. The TSA develops broad policies to protect the U.S. transportation system, including highways, railroads, buses, mass transit systems, ports, pipelines, and intermodal freight facilities. It fulfills this mission in conjunction with other federal agencies and state partners. However, the TSA's primary focus is on airport security and the prevention of aircraft hijacking. It is responsible for screening passengers and baggage at more than 450 U.S. airports, employing screening officers in airports, armed Federal Air Marshals on planes, mobile teams of dog ...

Airport
An airport is an aerodrome with extended facilities, mostly for commercial air transport. Airports usually consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off and to land or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals, to maintain and monitor aircraft. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services. In some countries, the US in particular, airports also typically have one or more fixed-base operators, serving general aviation. Operating airports is extremely complicated, with a complex system of aircraft support services, passenger services, and aircraft control services contained within the operation. Thus airports can be major employers, as well as important hubs for to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AIT Passenger Checkpoint Video
An ait (, like ''eight'') or eyot () is a small island. It is especially used to refer to river islands found on the River Thames and its tributaries in England. Aits are typically formed by the deposit of sediment in the water, which accumulates. An ait is characteristically long and narrow, and may become a permanent island should it become secured and protected by growing vegetation. However, aits may also be eroded: the resulting sediment is deposited further downstream and could result in another ait. A channel with numerous aits is called a braided channel. Etymology The word derives from Old English ''iggath'' (or ''igeth''); the root of the word, ''ieg'', meaning island, with a diminutive suffix. References in literature Although not common in 21st-century English, "ait" or "eyot" appears in J. R. R. Tolkien's ''The Lord of the Rings'', Charles Dickens's ''Bleak House'', and Thackeray's ''Vanity Fair''. (Google Ngram Viewer) Joyce Cary used "eyot" in ''The Horse' ...
