Abstract
The present invention provides devices and methods for the impregnation of air with the vapor or aerosol of a substance in a ‘controllable manner to enable the testing or training of detection means to evaluate and quantify the presence of the substance in an enclosed volume, and iη• particular to enable production of training aids and quality assurance test items for use in canine-olfaction based security screening.
Claims12
A method for the impregnation of air with the vapour or aerosol of a substance in a repeatable and controlled manner to enable the testing or training of means for detecting to evaluate and quantify the presence of the substance in an enclosed volume in a real environment, comprising arranging for an airflow from said enclosed volume in said real environment to pass over a predetermined volume or predetermined surface area of the substance supported within a conduit having an inlet and an outlet for passage of the airflow at a predetermined flow rate for a predetermined period of time thereby impregnating air of said airflow with said vapour or aerosol of said substance in a repeatable and controlled manner, and further arranging for delivery of said impregnated air to said means for detecting the substance, wherein said real environment is the environment found at a real situation, as opposed to a simulated environment which is a fake or mock environment that seeks to emulate the characteristics of said real environment.
A method for producing a training aid for detection dog training, comprising arranging for an airflow from an enclosed volume in a real environment to pass over a predetermined volume or predetermined surface area of a substance supported within a conduit having an inlet and an outlet for passage of the airflow at a predetermined flow rate for a predetermined period of time thereby impregnating air of said airflow with a vapour or aerosol of said substance in a repeatable and controlled manner, and adsorbing said impregnated air onto a substrate, wherein the substrate comprising the substance is the training aid, and wherein said real environment is the environment found at a real situation, as opposed to a simulated environment which is a fake or mock environment that seeks to emulate the characteristics of said real environment.
