Pneumatic Vacuum System for the Delivery of Odorant Emission from Scented Substrates

Abstract

The controlled delivery of odorant emissions is the primary function of this invention. Containment of the odorant emission is achieved by storing the scented material in a low vacuum chamber sealed by pair of solenoid valves at its openings. The opposite end of each solenoid valve is connected either to the ingress or egress manifold. A vacuum pump induces airflow through a chamber when the corresponding solenoids valves are opened, thereby delivering the scent into the atmosphere. An embedded micro-controller has direct control of the electromechanical devices (solenoid valves and vacuum relay). External hardware may signal the micro-controller. Additionally, application software such as those found in computer gaming, computer simulated training, interactive programs, and broadband technologies can source software enabling communication with the micro-controller over a USB port. As such, an olfactory feedback system can be realized.
