Abstract
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.
