Abstract: A portable device is disclosed which can deliver various combinations of scents in rapid succession directly to a user's nose. The device uses a blower fan (2) which forces air through a fragrance chamber (4). The flow into the chamber is regulated by an inlet valve (5) and an outlet valve (6). The valves (5,6) can be manually, electrically or pneumatically actuated. The valves (5,6) can be of an on/off or proportional flow type. The air carries away the scent molecules which have entered the gas phase. This air is then mixed with the air from all other fragrance holders in the packed bed mixer (11). The final mixture is delivered to the user via nasal tubing (20) and is emitted right below the wearer's nose. A mask covering the nose can be used to deliver the scent to the user. The scent is then drawn away from the nose and into a scent scrubber (38).

Abstract: A dynamic alloy wire valve for a multimedia linked scent delivery system consists of a hollow body with one flapper valve inlet which comes directly from a compressor and multiple flapper outlets, each of which feeds a separate fragrance air inlet. Inside the hollow body there is gang of flapper valves, which are arranged radially around a center spindle. At the other end of the flapper valve is valve tip, which fits snugly into a flapper valve seat. The flat metal leaf that forms the body of this flapper valve has an inherent spring tension much like a leaf spring. This spring tension normally keeps the valve tip pressed snugly against the valve seat, in the normally closed position. On the other side of the valve tip, there is attached a valve opener made from a dynamic alloy wire.

Abstract: A device to deliver various combinations of scents in rapid succession to a user's nose in conjunction with video graphic images and or sounds. The device consists of an air compressor which forces air through a bank of valves. The valves can be mechanically, electrically or pneumatically actuated. The valves can be of an on/off or proportional flow type. Each valve delivers compressed air to a fragrance holder. The air carries away the scent molecules which have entered the gas phase. This air is then mixed with air from all other fragrance holders, whose inlet valves were open, in the packed column. The final mixture is delivered to the user via nasal tubing and is emitted right below the wearer's nose. Other devices such as a mask covering the nose or a stand, which the user positions their face next to, can be used to deliver the scent to the user. The scent is then drawn away into a scent scrubber.
