Active carbon filters and systems that are operative to detect active carbon filter degradations are provided. The active carbon filter can include a carbon filter comprising activated carbon and defining a filter surface; a first piezoelectric wafer active sensor on the filter surface that is electrically isolated from the carbon filter; and a second piezoelectric wafer active sensor on the filter surface that is electrically connected to the filter surface; and an impedance monitoring device electrically connected to the first piezoelectric wafer active sensor and the second piezoelectric wafer active sensor. Methods are also disclosed for determining if any degradation has occurred in an active carbon filter.

Methods and sensors for the detection of active carbon filters degradation with EMIS-ECIS PWAS

A system for detecting atmospheric contamination, the system comprising a laser operable to generate an infrared light beam comprising a longitudinal component and a transverse component, the laser remote from the atmospheric contamination, and a processor operable to process a flouresence resulting from contact between the atmospheric contamination and an ultraviolet light being generated from the longitudinal and transverse components of the infrared light of the laser, wherein the processor determines the identity of the fluorescence by comparing the fluorescence to known fluorescence.

Remote laser assisted biological aerosol standoff detection in atmosphere

A method used to detect and identify biological substances suspended in air in the form of aerosols or clouds including generating a remote infrared light beam directed toward the atmospheric contamination, producing an ultraviolet light beam from the infrared light beam by compression via the air through which the IR beam travels, and producing fluorescence of the atmospheric contamination, when the generated ultraviolet light contacts the atmospheric contamination. The fluorescent signals are then processed in order to identify the nature of the atmospheric contamination.
