Tripwire Interactive Games
A tripwire is a passive triggering mechanism. Typically, a wire or cord is attached to a device for detecting or reacting to physical movement. Military applications Such tripwires may be attached to one or more mines – especially fragmentation or bounding mines – in order to increase the area where triggering may occur.. Trip wires are frequently used in booby traps—where either a tug on the wire, or the release of tension on it, will trigger the explosives. Soldiers sometimes detect the presence of tripwires by spraying the area with Silly String. It will settle to the ground in areas where there are no wires. Where wires are present, the "strings" will rest on the taut wires without triggering the explosive, due to its light weight. Its use in detecting tripwires was first discovered in 1993 by Sergeant First Class (SFC) David B. Chandler, Chief Instructor of the U.S. Army's Sapper Leader Course. That year it was introduced to students attending the course, an ...

Land Mine
A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both. Landmines are typically laid throughout an area, creating a ''minefield'' which is dangerous to cross. The use of land mines is controversial because of their potential as indiscriminate weapons. They can remain dangerous many years after a conflict has ended, harming civilians and the economy. Seventy-eight countries are contaminated with land mines and 15,000–20,000 people are killed every year while many more are injured. Approximately 80% of land mine casualties are civilians, with children as the ...

Bounding Mine
{{Unreferenced, date=May 2021 A bounding mine is an anti-personnel mine designed to be used in open areas. When it is tripped, a small propelling charge launches the body of the mine 3 to 4 feet (90 to 120 cm) into the air, where the main charge detonates and sprays fragmentation at roughly waist height. The original World War II German S-mine has been widely influential. Other countries that have employed bounding mines in war include the United States, United Kingdom, the Soviet Union, Vietnam and countries of former Yugoslavia. China and Italy have also produced them. Some American mines designed for this purpose used a standard 60 mm HE mortar round with an improvised time delay fuse which is activated by the propelling charge. Bounding mines are more expensive than typical anti-personnel blast mines, and they do not lend themselves to scatterable designs. Because they are designed to be buried, they are appropriate for command-detonated ambushes, but tripwire operati ...

Booby Trap
A booby trap is a device or setup that is intended to kill, harm or surprise a human or another animal. It is triggered by the presence or actions of the victim and sometimes has some form of bait designed to lure the victim towards it. The trap may be set to act upon trespassers that enter restricted areas, and it can be triggered when the victim performs an action (e.g., opening a door, picking something up, or switching something on). It can also be triggered by vehicles driving along a road, as in the case of improvised explosive devices (IEDs). Booby traps should not be confused with mantraps which are designed to catch a person. Lethal booby traps are often used in warfare, particularly guerrilla warfare, and traps designed to cause injury or pain are also sometimes used by criminals wanting to protect drugs or other illicit property, and by some owners of legal property who wish to protect it from theft. Booby traps which merely cause discomfort or embarrassment are a popul ...

Line Laser
A line laser is a device that employs a laser and an optical lens to project the laser beam as a line rather than a point (e.g. laser pointer). This may be achieved by passing the beam through a cylindrical lens or a Powell lens. Depending on the application, independent line lasers may be used to generate lines, or multiple line lasers may be used together to produce crosses or other composite patterns. In civil engineering and interior design, line lasers are used to assist in levelling building sites and structures. Multiple lines may be generated for use with image processing. Applications * Diffractive beam splitter * Calibration * Spirit level * David Laserscanner * Light section * Image processing An image is a visual representation of something. It can be two-dimensional, three-dimensional, or somehow otherwise feed into the visual system to convey information. An image can be an artifact, such as a photograph or other two-dimensiona ... * Machine vision * 3D sca ...

Conveyor Belt
A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). A belt conveyor system is one of many types of conveyor systems. A belt conveyor system consists of two or more pulleys (sometimes referred to as drums), with a closed loop of carrying medium—the conveyor belt—that rotates about them. One or both of the pulleys are powered, moving the belt and the material on the belt forward. The powered pulley is called the drive pulley while the unpowered pulley is called the idler pulley. There are two main industrial classes of belt conveyors; Those in general material handling such as those moving boxes along inside a factory and bulk material handling such as those used to transport large volumes of resources and agricultural materials, such as grain, salt, coal, ore, sand, overburden and more. Overview Conveyors are durable and reliable components used in automated distribution and warehousing, as well as manufacturing and produ ...

Emergency Stop
A kill switch, also known as an emergency stop (E-stop), emergency off (EMO) and as an emergency power off (EPO), is a safety mechanism used to shut off machinery in an emergency, when it cannot be shut down in the usual manner. Unlike a normal shut-down switch or shut-down procedure, which shuts down all systems in order and turns off the machine without damage, a kill switch is designed and configured to abort the operation as quickly as possible (even if it damages the equipment) and to be operated simply and quickly (so that even a panicked operator with impaired executive functions or a bystander can activate it). Kill switches are usually designed to be noticeable, even to an untrained operator or a bystander. Some kill switches feature a removable, protective barrier against accidental activation (e.g. a plastic cover that must be lifted or glass that must be broken), known as a mollyguard. Kill switches are features of mechanisms whose normal operation or foreseeable mi ...

Anti-personnel Weapons
An anti-personnel weapon is a weapon primarily used to maim or kill infantry and other personnel not behind Armour, armor, as opposed to attacking structures or vehicles, or hunting Game (hunting), game. The development of defensive fortification and combat vehicles gave rise to weapons designed specifically to attack them, and thus a need to distinguish between those systems and ones intended to attack people. For instance, an anti-personnel land mine, landmine will explode into small and sharp splinters that tear flesh but have little effect on metal surfaces, while anti-tank mines have considerably different design, using much more explosive power to effect damage to armored fighting vehicles, or use explosively formed penetrators to punch through armor plating. Many modern weapons systems can be employed in different roles. For example, a tank gun, tank's main gun can fire armor-piercing ammunition in the anti-tank role, high-explosive ammunition in the anti-structure role and ...

Warning Systems
Warning system is any system of biological or technical nature deployed by an individual or group to inform of a future danger. Its purpose is to enable the deployer of the warning system to prepare for the danger and act accordingly to mitigate or avoid it. Warnings cannot be effective unless people react to them. People are more likely to ignore a system that regularly produces false warnings (the cry-wolf effect), but reducing the number of false warnings generally also increases the risk of not giving a warning when it is needed. Some warnings are non-specific: for instance, the probability of an earthquake of a certain magnitude in a certain area over the next decade. Such warnings cannot be used to guide short-term precautions such as evacuation. Opportunities to take long-term precautions, such as better building codes and disaster preparedness, may be ignored.
