    • Apparatus and methods for fragrance sensory stimulation connected to a multimedia source that has at least one audiovisual signal connected to an audiovisual display, and also has fragrance information synchronized with the audiovisual signal is disclosed. In preferred embodiments, a fragrance generator processes the fragrance information into a fragrance signal and at least one fragrance control system accepts a fragrance signal as an input, and generates a control signal and a burst of compressed gas. In turn, a fragrance delivery system preferably comprising a plurality of fragrance chemicals in communication with the burst of compressed gas selectively volatilizes the fragrance chemicals so that a short burst of fragrance is sensed by the subject. Preferably, this short burst is followed by a purging burst that clears the fragrance so that another subsequent fragrance is easier to sense. The compressed gas may be generated by a source of compressed gas or a compressor. In certain embodiments, the fragrance delivery system comprises an indexing turret containing a plurality of ports, each port containing one of said plurality of fragrance chemicals. In other preferred embodiment, a multiport micro-valve or array of such valves contains an absorbent material impregnated with a fragrance in each port.
    • 公开了连接到具有连接到视听显示器的至少一个视听信号的多媒体源的香味感觉刺激的装置和方法,并且还具有与视听信号同步的香味信息。 在优选实施例中,香味发生器将香料信息处理成香味信号,并且至少一个香味控制系统接受香味信号作为输入,并产生控制信号和压缩气体的爆发。 反过来,香料递送系统优选地包括与压缩气体爆发相连通的多种香料化学品,选择性挥发香料化学品,使得受试者感觉到短暂的香味。 优选地,这种短脉冲之后是清除香料,从而使另一种后续的香料更易于感觉。 压缩气体可以由压缩气体源或压缩机产生。 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,每个端口包含所述多种香料化学品之一。 在另一优选实施例中,这种阀的多端口微型阀或阵列包含在每个端口中浸渍有香料的吸收材料。
