Assessing odors

摘要

In some aspects, olfactory devices include a housing having a first inlet and a second inlet, an ambient air inlet cartridge defining a channel in fluid communication with the first inlet, and a position sensor. The ambient air inlet cartridge includes a first member defining a first orifice, and a second member moveable relative to the first member, the second member defining a second orifice, where a degree of overlap between the first orifice and the second orifice controls a flow capacity of the channel. The position sensor signals the degree of overlap between the first orifice and the second orifice.

主权项

1. An olfactory device comprising:
a housing having a first inlet and a second inlet; an ambient air inlet cartridge defining a channel in fluid communication with the first inlet, the ambient air inlet cartridge comprising:
a first member having a first orifice;a second member having a second orifice; wherein the second member is movable relative to the first member to create a continuously-variable ambient air inlet size; and a position sensor generating at least one or more values indicating the degree of overlap between the first orifice and the second orifice; and a controller adapted to receive the one or more values from the position sensor and to determine a dilution-to-threshold value based at least in part on one or more values.
