Provided is an olfactory data sharing terminal including a receiver configured to receive olfactory data obtained by sensing an odor of an object through an olfactory sensor; a preference determiner configured to determine whether a user prefers the received olfactory data, based on a user olfactory function f.sub.user(x); and a display displaying a user preference for the received olfactory data.

Vapor wake detection is a highly advantageous method and system for detecting explosives and other illicit substances. With vapor wake detection, a canine and a handler are used; however, unlike other detection schemes, the canine leads the handler. After the handler positions the canine in a desired location, the canine detects scents in the air that come to the canine. When the canine detects a trained scent, the canine leads the handler to or follows behind the carrier of the item with the scent. Once the carrier is identified by the handler, the proper personnel are contacted. To implement vapor wake detection effectively, specific rigorous training is utilized.

The present invention relates to non-invasive method and system for characterising and certifying cognitive activities by detecting gaseous substances emitted by an organism, by means of the respiration, perspiration, and/or secretion, and changes measureable by sensors during said cognitive activities. Substance detection makes it possible to characterise the olfactory signal in order to determine and certify whether or not a cognitive activity has occurred and to classify said signals into different categories of cognitive activities.

The invention relates to a method of screening a fragrance or a flavouring using functional Magnetic Resonance Imaging to assess the ability of said fragrance or flavouring to elicit a “well-being” effect.

Apparatus (1000) and method for automatically detecting odorant substances based on use of nematodes that includes a mechanical selection unit (100) configured to select nematodes in adult stage from an initial nematode population obtaining an intermediate nematode population, a nematode optical selection unit (200) configured to select from the intermediate population a final population of nematodes in adult stage and to select nematodes in young adult stage from nematodes in egg producing adult stage to be sent to a measurement unit (300) configured to detect the response of nematodes of the final population to a stimulus of an odorant substance, the mechanical selection unit (100) being connected to the optical selection unit (200) by a connection channel with an at least three way branch and the optical selection unit (200) being connected to the measurement unit (300) by a loading microchannel.

Methods and systems for detecting and indicating the presence of undesirable substances in ingestible substance such as food or beverages. More specifically, systems and methods for nonvisually and concealably indicating and detecting the presence of unwanted or undesired drugs in beverages and/or food.

In an electronic nose apparatus and method based on spectrum analysis, 1) a gaseous sample is dissolved into a solvent in an impinger, and the sample dissolved into the solvent is introduced into an RF resonator, and 2) RF having various absorption spectra according to materials are generated in the RF resonator, and the type of gas is determined through spectrum analysis so that an electronic nose is implemented. In this way, it is possible to overcome the resolution of gas chromatography (GC) and a sensor array and a limited number of multi-channel sensors (the number of channels).

The present invention makes it possible to represent or synthesize any odor by separating the odor into a combination of a relatively small number of odors, similarly to separating a color into three primary colors. Since the “primary odors” corresponding to the primary colors have not yet been ascertained, the present invention provides a feasible method and apparatus in which, instead of presetting such fixed primary odors, the separation, synthesis, and the like can be performed by selecting a subset of odors from among a set consisting of a plurality of odors which subset or odors enables approximation of other odors as much as possible by mixture.

A method of assessing the impact of a test perfume composition on the well-being of human subjects is provided, as well as a method of preparing or optimizing a perfume composition for enhancing the well-being of a human subject, perfume compositions that enhance the well-being, and consumer products containing them.

The control device includes a control unit that is configured to control an unmanned aerial vehicle that collects a collection object. The control unit acquires information that indicates an odor intensity of the collection object to be collected, and determines a flight route of the unmanned aerial vehicle after the unmanned aerial vehicle picks up the collection object located at a collection point, based on the information that indicates the odor intensity of the collection object.
