Efforts to reduce threats on public places in the transport facilities are priority aim

Based on the fact that Flammable and explosive liquids has lower electrical conductivity and dialectical permeability compared to safe liquids

Uses method of Quasistatic electrical tomography for measurement of electrical and dialectical properties of liquids.

Designed in hand held and user friendly device

1. Alternating voltage is on active electrode.

2. Obtained signals are measured on receiver electrodes.

3. Permittivity and conductivity are calculated based on results independently on wall thickness.

4. The results are compared with a database of dangerous liquids.

5. Light and sound signals are obtained.

Operation principle

High speed and accuracy of the analysis, Detection of a vast list of liquids, Possibility to provide mass screening of containers of

various forms, colors and materials

LQtest device will prevent carrying dangerous liquids aboard the aircraft, provide safe, comfortable for passengers, reliable and fast mass screening of liquids in any nonmetallic vessels, at any environmental conditions,at any level of transport congestion

Detection time………………………………………………………0,5 sec Minimum volume of liquid………………………………………50 ml Wall thickness ……………………………………….……up to 8 mm Indicators…………………………………………………..Light & sound Weight…………………………………………………………………….165 g Dimensions……………………………………………207×70×30 mm Number of tested liquids…………………………more than 800

Acetone: dangerous Vodka: safe White spirit: dangerous Shampoo: safe

Combustive-lubricating materials, oil products

Alcohol containing liquids (ethylene above 60%)

Liquid explosives and ingredients

Beverages (below 60%)

Liquid household chemicals

Perfumes, cosmetics (alcohol content below 60%)

Detects as dangerous:

Liquid nitroethers (nitroglycol, diethyleneglycol dinitrate, iso-propylnitrate)

Liquid explosives (mixtures based on caoutchouk and nitroethers)

Nitroolefins, nitromethanes Active bonding agents of solid propellants (azidoethanol,

glycidyl nitrate, glycyl dinitrate, glycidylazide polymer, ternary mixture based on nitrazolefin derivatives)

Mixture of mineral oil, ammonium nitrate, emulsifier and water (a substrate for emulsive explosives)

Mononitrotoluenes Halogen containing solvents, such as carbon tetrachloride,

ethylene dibromide, propylene dibromide.

Russian airports: Sheremetyevo, Domodedovo, Vnukovo.

Novosibirsk, Krasnodar, Voronezh, Tyumen, Ufa, Barnaul, Minsk and others.

During 2012 transport Police detected and confiscated more than 1000 liters of high-flammable liquid

Ratio – the device intended for revealing of potentially dangerous objects in footwear

Device operating is based on application of multizonal wideband tomography technology with application of neural network and optimizing algorithms of processing the information and the inverse problem solving for search inhomogeneity and abnormal areas in inspected objects.

Passenger rises on Ratio’s marked areas. The device makes necessary measurements within 1-2 seconds and finds out (at their presence) stranger inclusions in footwear, including metal subjects

Indication (dangerous/safe object) is available on the device and is duplicated on the monitor.

The technology realized in the device, allows to find out any dangerous inclusions (both metal, and nonmetallic, including explosives, weapons, etc.)

Inclusions can be directly built in a sole or enclosed in footwear

Device successfully passed tests in The State Scientifically Research Institute of Civil Aviation and in Airport Sheremetyevo, practical approbation at Airport Vnukovo (Moscow). Certificate of Conformance № ROSS RU.ML04.Н00751.
