  • Patent number: 10123509
    Abstract: 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.

  • Patent number: 9310781
    Abstract: Disclosed herein is an apparatus and method for interaction between content and an olfactory recognition device. In the method for interaction between an olfactory recognition device and a content device, the method allows the olfactory recognition device to interact with the content device. If a connection to the content device has been made to enable data communication with the content device, an open signal is transmitted to the content device. As a response to the open signal, an approval signal is received from the content device. A device information datasheet that is information about the olfactory recognition device is transmitted to the content device in response to the approval signal. An acknowledgement signal is received from the content device.

  • Patent number: 9028751
    Abstract: The present invention relates to a system and method for dynamically controlling odor emission. The system comprises an odor measurement tool, a weather condition measurement tool, a processing module and a controller. The odor measurement tool is adapted to measure an odor level. The weather condition measurement tool is adapted to measure at least one weather condition. The processing module is adapted to calculate an odor emission threshold based on the measured odor level, the at least one weather condition, an atmospheric dispersion model and a predetermined remote odor level threshold. The controller is adapted to control the odor emission below the odor emission threshold.

  • Patent number: 9021860
    Abstract: A self-contained mobile apparatus which replicates the evaluation of scents, fragrances, aromas and odors in controlled and home environments. The apparatus simulates various stages of the consumer experience and has adjustable settings for dosing, air flow, and room size. The scented compound sample is placed within a cabinet having an enclosed sample chamber which is connected to an upward facing sample tube. An air fan is mounted within the sample chamber which circulates and controls sample air flow upward to a testing station wherein the sample air flow is tested for the identification and the concentration of the scent contained therein. A return air chamber and filter are mounted below the testing station. The filtered return air is controlled downward by a return air blower to provide an exhaust out through the bottom of the apparatus.

    Abstract: The present disclosure relates to methods and systems for calculating a food additive. A first method includes identifying chemical compounds of an averse food ingredient, identifying chemical compounds of a flavorful food ingredient and calculating a set of chemical compounds for the food additive such that an olfactory perception of a mixture of the averse food ingredient, the flavorful food ingredient and the food additive is the same as an olfactory perception of only the flavorful food ingredient. A first device includes a database storing information identifying chemical compounds of an averse food ingredient and identifying chemical compounds of a flavorful food ingredient, and a processor for calculating a food additive such that an olfactory perception of flavors of a mixture of the averse food ingredient, the flavorful food ingredient and the food additive is the same as an olfactory perception of only the flavorful food ingredient.

  • Patent number: 8959982
    Abstract: 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.
