    • 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.
    • 公开了一种与连接到视听显示器的多媒体源同步的香味感觉刺激系统。 香味发生器将来自视听源的香味信息处理成标志信号,并且香味控制系统接受香味信号作为输入并产生控制信号和可控气流。 反过来,具有与受控气流连通的多种香料化学品的香味递送系统选择性挥发香料化学品,从而将短暂的香味突发传送给使用者。 在某些实施方案中,香料递送系统包括包含多个端口的分度转台,每个端口包含一种香料化学品。 在另一优选实施例中,多口微型阀或这种阀的阵列包含在每个端口中浸渍有香料的吸收材料。
