In variants, a method for sensory characterization can include: determining attributes for a sample, collecting sensory data for the sample, determining a sensory characterization model, training the sensory characterization model based on the attributes and the sensory data, determining attributes for a test sample, and predicting a sensory characterization for the test sample using the sensory characterization model.

An odor evaluation device, including: a gas chromatograph including a separation column configured to temporally separate a plurality of components contained in an odoriferous analysis-target gas; a timing detector configured to detect, for each of the plurality of components, a timing at which the component exits from the separation column; a gas collector configured to collect, into a sample bag, a gas containing all or some of the components exiting from the separation column when the analysis-target gas is passed through the separation column; a timing setter configured to allow a setting of a timing at which a component contained in the gas to be collected into the sample bag exits from the separation column; and a gas introducer configured to introduce a dilution gas into a passage connecting the separation column and the sample bag.

The present disclosure provides, method, a system, and apparatus for identifying odorants. For example, the apparatus performs sensing an odorant using an olfactory sensor, encoding the sensed odorant to an electrical signal using an input processor, determining an identity representation of the odorant based on the encoded electrical signal, and determining odorant information using a time-dependent hash code based on the identity representation of the odorant.

The subject matter herein includes apparatus and techniques, such as can be used to automatically assess dominance of sensation. For example, a technique for such assessment can include generating a representation of two or more sensations for display to a user, receiving respective selections of respective sensations amongst the two or more sensations in response to display of the representation. As an example, receiving the respective selections of respective sensations can include obtaining data indicative of a magnitude of the respective sensations corresponding to the respective selections and obtaining data indicative of a temporal relationship between the respective selections, providing time-intensity and dominance of sensation data contemporaneously.

In an example, a sample collection apparatus to collect sample from a detection subject includes a circumferential ring tubing surrounding an interior and configured to be moved between bottom ring tubing position and top ring tubing position. The circumferential ring tubing includes air nozzles along a circumferential length of the ring tubing to direct air flow toward the interior as the ring tubing is moved from the top ring tubing position to the bottom ring tubing position, to blow air toward the detection subject in a sample collection zone in the interior and to push a sample of the detection subject via an air flow toward a platform on which the detection subject is positioned. The sample includes particles and/or vapor of the detection subject. A receptacle is disposed below the platform to collect the sample carried by the air flow through collection openings of the platform to the receptacle.

Described is an apparatus (1) for measuring odours comprising: a measuring chamber (2); an intake duct (4) having two ends, an inlet end (4a) in communication with the outside environment and an outlet end (4b) in connection with the measuring chamber; at least one sensor (3), positioned inside the measuring chamber (2) and designed for measuring the olfactory properties of a gas; a control unit (6) designed for processing signals coming from the at least one sensor (3) and providing a parameter representing the odours measured in the gas to be analysed; a suction device (5), positioned inside the intake duct (4) and designed to circulate the gas inside the apparatus (1); a cleaning device designed for restoring the characteristics of the at least one sensor (3) following a measurement, wherein the cleaning device is designed for generating ozone inside the apparatus (1).

A system and method for identifying different types of produce at checkout based on an odor emitted by the produce is provided herein. An olfactometer is used to detect chemical compounds contributing to an odor of the produce at checkout. Based on the detected odor, an odor profile is constructed and compared to one or more baseline odor profiles stored in memory. Based on the comparison results, a freshness date for the produce is determined provided to a device associated with the shopper. So informed, the shopper is aware of how long the produce will be considered fresh. Additionally, one or more reminder messages may be sent to a device associated with the shopper reminding them of the freshness date for the produce they purchased.

Disclosed herein are olfactory diagnostic kits and methods for screening for an olfactory dysfunction. Also disclosed are olfactory training kits and methods for treating an olfactory dysfunction in a subject. Also disclosed is a method for diagnosing a subject for an olfactory dysfunction. Also disclosed is a method for training a subject with an olfactory dysfunction.

A method of use encompassing coded sampling containers that may be implemented in two phases, the results of which may be further processed to arrive at a final score. The first phase incorporates four sampling containers in the context of a series of triangle tests to arrive at a first subscore. The second phase uses two of the coded containers and requires the participants to assess the degree to which the contents of the containers reflect a particular characteristic on a scale. The responses of each participant may be scored by summing the differences between the actual answers and the correct answers to arrive as a second subscore. A final score may be calculated by subtracting the first subscore from the second subscore.

The present disclosure relates to an apparatus (100) for quantitative assessment of olfactory dysfunctions and neurocognitive deficits, the apparatus includes first filters (104-1) adapted to sterilize air received from an air pump, a second filter (106) filter odor molecules from the air, a manifold (108) adapted to split the sterilized air into a plurality of channels, at least one channel carries the sterilized air to a first MFC (110) and adjacent channels carry sterilized air to second MFCs (112). Each container in a reservoir (114) filled with an odorant different from adjacent containers, and a nozzle (118) adapted to receive the odorized air from the reservoir that is inhaled by a subject through an odor delivery unit (124), based on degree of variation in volumetric concentration of the odorants, quantitative assessment of olfactory dysfunction is determined.
