Abstract: A system for collecting cannabis and the psychoactive component tetrahydrocannabinol from a sample of exhaled breath is disclosed. Single or multiple exhaled breaths are conditioned by removing contaminants, and regulating flow rate and/or pressure to collect a sample of tetrahydrocannabinol for timely local or remote analysis. The cannabis detection system comprises a containment trap for removing interfering materials from the breath of the subject and a collection component for sampling components of breath introduced into the system through the containment trap for analysis to determine a presence of THC in the breath.

Abstract: Body-mounted threat detection systems and methods of detecting threats using body-mounted threat detection systems are provided. Threats detected include guns, knives and/or explosives. A body-mounted transmitter directs electromagnetic radiation towards the target and a body-mounted receiver receives electromagnetic radiation returned from the target. The return signal is analyzed and a signal indicative of the presence or absence of a threat is generated.

Abstract: A controlled substance Intercept system for collecting and detecting levels of one or more controlled substances in the breath of a subject and intercepting electric operation of a device, comprising: a sample capture module; a THC identification module; and an intercept module. The THC identification module sends an electric or optical signal to the intercept module if a level of controlled substance present in a sample captured in the sample capture, module exceeds a set threshold, for use in applications to enable or disable operation of equipment such as motor vehicles and construction equipment, and to enable or disable access to locations where impairment would pose a hazard, such as air or marine traffic control centers.

Abstract: A system for collecting cannabis and the psychoactive component tetrahydrocannabinol or other controlled substances from a sample of exhaled breath. Single or multiple exhaled breaths are conditioned by removing contaminants, and regulating flow rate and/or pressure to collect a sample of tetrahydrocannabinol for timely local or remote analysis using FAIMS. The cannabis detection system comprises a containment trap for removing interfering materials from the breath of the subject and a collection component for sampling components of breath introduced into the system through the containment trap for FAIMS analysis to determine the level of THC or other controlled substance in the breath.
