- Crime-fighting sensors.
Systems designed to identify ceramic sensors Systems designed to identify ceramic weapons, plastic explosives, chemical weapons, and organic materials are being developed to help protect citizens from terrorism and aid police in solving crimes. Not too long ago, terrorism was something that Americans only heard about on the news. But ......
- New way to find terrorist explosives
Israeli researchers have developed a device that identifies a previously undetectable explosive commonly used by terrorists. The device is called a Peroxide Explosive Tester (PET). It determines whether or not a suspicious substance is triacetone triperoxide (TATP). The PET, which resembles a three-color ballpoint pen, releases three chemical mixtures that ......

- Better intrinsically safe than
sorry.
Intrinsically safe devices and systems are becoming more common at sites with a potential for fire and explosion. At facilities where there are processes requiring flammable or explosive materials, operating at low energy can prevent electrical devices (during normal or fault conditions of the circuits) from creating arcs, sparks, or ......
- Flow control in hazardous environments
IMAGE ILLUSTRATION 1 It's difficult to provide a closed-looped control of fluid flow in an intrinsically safe zone, because the device must meet certain electrical resistance, capacitance, and inductance requirements. It must have more than two independent means of failure-one mechanical and one electrical-before it ignites. The most stringent of ......
