The present disclosure relates generally to a system and method for detecting or indicating a state of impairment of a test subject or user due to drugs or alcohol, and more particularly to a method, system and application or software program configured to creating a virtual-reality ('VR') environment that implements drug and alcohol impairment tests, and which utilizes eye tracking technology to detect or indicate impairment.

Roadside impairment sensor

An apparatus for extracting a material from a liquid includes a concentration stage having a filter, a first path from the filter, and a second path from the filter. Under this configuration, the concentration stage accepts an initial liquid volume. A first liquid not having material collected by the filter is passed along the first path, and concentrated liquid having material therein, which is entrapped by the filter, is directed to the second path. The apparatus also includes an aerosolizing stage coupled to the concentration stage that converts the concentrated liquid into an aerosol and a drying stage that dries the aerosol such that material extracted from the aerosol onto a material substrate.

Extraction of materials from liquids

An apparatus for extracting a material from a liquid includes a concentration stage having a tangential flow filter, a first path from the tangential flow filter, and a second path from the tangential flow filter. Under this configuration, the concentration stage accepts an initial liquid volume. A first liquid not having material collected by the tangential flow filter is passed along the first path, and concentrated liquid having material therein, which is entrapped by the filter, is directed to the second path. The apparatus also includes an aerosolizing stage coupled to the concentration stage that converts the concentrated liquid into an aerosol and a drying stage that dries the aerosol such that material extracted from the aerosol onto a material substrate.
