Abstract: A method of identification of an odorprint of a health state of a living organism can include monitoring the composition of volatile compounds emitted by the organism using the olfactory system of the service animal equipped with the brain machine interface. The method can include finding the specific signature of the bio-electronic nose signal responsible for identification of a volatile compound odorprint of a health state of an organism. The method can include applying machine learning techniques to multi-component bio-electronic nose signals. The method can include identifying specific volatile compounds or their ratios carrying information about a health state of an organism.

Abstract: An odor training and detection system can include multiple service animals. Each service animal can be provided with a means by which neural activity can be read from the olfactory system. Each service animal can be associated with an edge computing device containing an updateable local database and enabled with wireless communication. Each service animal can be equipped with one or multiple cloud-based servers and databases. A family of anchor odor sets and computational methods can enable the alignment of olfactory maps across individual animals into a common coordinate framework. Further disclosed is a means of computing and communicating (in a privacy-preserving manner if desirable) federated updates to olfactory decoding models between the local databases on the edge and the cloud database(s).

Abstract: A method of training a rodent to identify pairs of same or different odors, whereby the rodent learns the rule irrespective of the particular odors. Once trained, the rodent can be used to measure perceptual odor similarities between members of pairs of odors, which odors may be unrelated to the odors the rodent was trained on.

Abstract: In certain embodiments, an odor delivery device for a VR/AR system has independently controllable micropumps and dedicated tubing for each micropump that dispenses pumped air from the device. The tubings can receive scented material such that, when air is pumped by the corresponding micropump through a tubing, scented air flow is dispensed by the tubing from the device. When multiple tubings have multiple differently scented materials, corresponding differently scented air flows concurrently dispensed by the tubings are mixed together only outside the device. In one implementation, a pump unit has the micropumps and tubing for each micropump and a cartridge unit having tubing for each micropump in the pump unit, can be removably mated to the pump unit. When the cartridge unit is mated to the pump unit, each tubing in the cartridge unit mates with corresponding tubing in the pump unit.

Abstract: An animal-based chemical detectors that can be customized to detect a wide variety of chemicals under real-world conditions. Methods and systems for brain/machine interface devices using electrodes to read odor-signatures from the patterns of activated glomeruli, for example in the rodent olfactory bulb.

Abstract: This disclosure provides methods for identification of olfactory sensosry neurons (OSN) that recognize specific odorants. The method comprises introducing into the OSN, a permanent activity marker which exhibits a detectable and permanent change upon activation of the neuron in response to an odorant and exposure to an exteranal stimulus, such as light. The OSN can be isolated and its receptor characterized.

Abstract: The capillary gun for delivery of ballistic particles to a target includes an inner capillary tube disposed concentrically within an outer capillary tube with the input end of the inner tube connected to a channel through which a continuous flow of high speed helium gas carrying ballistic particles is introduced. The outer capillary tube, which is connected to a vacuum source, has an outlet end that extends slightly beyond the end of the inner tube. A cap placed over the output end of the outer tube has an opening at its center through which the particles exit the device. The vacuum source applies continuous suction to the space between the outer tube and the inner tube, drawing the gas from the output end of the inner tube while the inertia of the accelerated particles causes them to continue in the axial direction through the exit opening for delivery to the target. Multiple particle injectors provide for the concurrent injection of different materials without disruption of the gas flow.
