Fragrance delivery for multimedia systems
View Patent ↗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.
1. An apparatus for fragrance sensory stimulation comprising:
a multimedia source comprising at least one audiovisual signal connected to an audiovisual display, and fragrance information synchronized with the audiovisual signal;
a fragrance generator for processing said fragrance information into a fragrance signal;
at least one fragrance control system that accepts a fragrance signal as an input, and generates a control signal and a controlled airflow; and
a fragrance delivery system connected to and controlled by the control signal, the fragrance delivery system comprising a plurality of fragrance chemicals in communication with the controlled airflow, a plurality of valves controlled by the control signal and connected to a corresponding plurality of wells wherein the wells, connect to a common delivery conduit,
whereby at least one of said fragrance chemicals is volatilized and the volatilized fragrance is collected in one of said wells and transferred to the common delivery conduit and sensed by a subject.
2. The apparatus for fragrance sensory stimulation according to claim 1 , wherein said plurality of valves comprise check valves and electronically controlled pneumatic valves.
3. The apparatus for fragrance sensory stimulation according to claim 1 , further comprising a transmitter connected to the fragrance generator and a receiver connected to the fragrance creation system, whereby the transmitter sends the fragrance signals to the receiver.
4. The apparatus for fragrance sensory stimulation according to claim 1 , further comprising a user interface worn by a user.
5. The apparatus for fragrance sensory stimulation according to claim 4 , wherein the user interface comprises a mask at least partially surrounding a user's face, and further comprising a scent releasing apparatus disposed near the user's nose.
6. The apparatus for fragrance sensory stimulation according to claim 4 , wherein the user interface comprises a helmet at least partially surrounding a user's face, and further comprising a scent releasing apparatus disposed near the user's nose.
7. The apparatus for fragrance sensory stimulation according to claim 4 , wherein the user interface comprises an earpiece attached to a user's ear and further comprising a scent releasing apparatus disposed near the user's nose.
8. The apparatus for fragrance sensory stimulation according to claim 4 , wherein the user interface comprises a pendant disposed near the user's chest and further comprising a scent releasing apparatus disposed near the user's nose.
9. The apparatus for fragrance sensory stimulation according to claim 1 , wherein a user interface is placed adjacent the user and further comprising a scent releasing apparatus disposed near the user's nose.
10. The apparatus of claim 1 , wherein the user interface comprises a base and a flexible, bendable stalk.
11. The apparatus of claim 9 , wherein the user interface comprises a game controller, a steering wheel connected to the game controller, and a flexible, bendable stalk.
