A system for fragrance sensory stimulation synchronized to a multimedia source connected to an audiovisual display is disclosed. A fragrance generator processes fragrance information from the audiovisual source into a flagrance signal, and a fragrance control system accepts the fragrance signal as an input and generates a control signal and a controlled airflow. In turn, a fragrance delivery system with a plurality of fragrance chemicals in communication with the controlled airflow selectively volatilizes the fragrance chemicals so that a short burst of fragrance is delivered to a user. In certain embodiments, the fragrance delivery system comprises an indexing turret containing a plurality of ports, each containing one fragrance chemical. In another preferred embodiment, a multi-port micro-valve or an array of such valves contains an absorbent material impregnated with a fragrance in each port.

Fragrance delivery for multimedia systems

Automatic material identification is achieved using infrared thermometry. A focused beam of high flux energy is passed through a dichroic beam-splitter to remove visible UV with the remaining infrared directed to the surface of the material to be identified. An infrared thermometer sensor is positioned to sense the magnitude of the energy received from the material surface with the magnitude of the energy being indicative of the type of material scattering such energy. Control apparatus are employed to provide control signals as a function of the type of material identified such that automatic process operations may be effected in accordance therewith.
