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 ...
An M40 circuit test set is packed in each case of six mines. When the mines are daisy-chained together, one firing device can detonate several mines. The mine can be detonated by any mechanism that activates the blasting cap. There are field-expedient methods of detonating the mine by tripwire, or by a timer, but these are rarely used.
It consists of tripwire around the area, linked to one or more flares. When the tripwire is triggered, as by someone unsuspectingly disturbing it, the flare is activated and begins burning. The light from the flare simultaneously warns that the perimeter may have been breached and also gives light for investigating. [2]
Oct. 2—The fate of a Derry Township man hinges on whom jurors believe. Prosecutors plan to present evidence during trial this week that William Joseph Dankesreiter Jr., 63, set up a trip wire at ...
Current through a wire coil produces a time-varying magnetic field that in turn induces currents in conductive objects in the ground. In turn, these currents generate a magnetic field that induces currents in a receiver coil, and the resulting changes in electric potential can be used to detect metal objects. Similar devices are used by hobbyists.
On firing, a metal base plate remains in the ground, while the mine body is thrown up by a small lifting charge, but remains attached to a strong wire tether. When the end of the tether is reached at a height of approximately 0.5 m, the main charge explodes and scatters fragments of the casing across a wide area.
A tripwire force (sometimes called a glass plate) is a strategic approach in deterrence theory. The tripwire force is a military force smaller than that of a potential adversary, which is designed to signal the defending side's commitment to an armed response to future aggression without triggering a security spiral .
A tripwire is a passive triggering mechanism such as a wire attached to a device. Tripwire or tripwires may also may refer to: Books. Tripwire, by Lee Child; ...
