    • A multimedia presentation system a projector to project images toward an audience. A plurality of nozzles are partially submerged in a body of water at locations between the projector and the audience. The plurality of nozzles are located at different distances from the projector. Each of the plurality of nozzles is arranged to produce a fan like water mist onto which the projector projects images. A controller is coupled to the projector and the plurality of nozzles. The controller causes the projector to project images and at least one of the plurality of nozzles to produce a water mist in a synchronized sequence such that the images appear at different distances from the projector at different times. The controller may further control the orientation of each nozzle to vary the distance by inclining the plane of the water mist relative to the surface of the body of water.
    • 一种多媒体演示系统,用于向观众投影图像的投影仪。 在投影机和观众之间的位置处,多个喷嘴部分地浸没在水体中。 多个喷嘴位于与投影仪不同的距离处。 多个喷嘴中的每一个布置成产生投影仪投影图像的风扇,如水雾。 控制器耦合到投影仪和多个喷嘴。 控制器使得投影仪投影图像和多个喷嘴中的至少一个以产生同步顺序的水雾,使得图像在不同时间出现在与投影仪不同的距离处。 控制器可以通过使水雾的平面相对于水体的表面倾斜来进一步控制每个喷嘴的取向以改变距离。

    • The present invention provides a means for producing a laminar output of fluid which is substantially turbulence free. The present invention utilizes an input tank or enclosure which includes turbulence reducing and flow straightening devices for producing a turbulent free output flow of water. This enclosure uses a tangential input port to introduce water to the enclosures which results in much more uniform and controllable flow profiles of the water through the device. The entire device may be situated entirely beneath the surface of a pool, pond or fountain, with a clear glass or plastic tube extending above the water level to provide a visibly nonintrusive protective path for the laminar output flow.
    • 本发明提供一种用于生产基本上无湍流的流体层流输出的方法。 本发明利用一种输入罐或外壳,其包括减少湍流和流动矫正装置,用于产生湍流的自由输出水流。 该外壳使用切向输入端口将水引入外壳,这导致水通过设备的更均匀和可控的流量分布。 整个设备可以完全位于游泳池,池塘或喷泉的表面下方,其中透明的玻璃或塑料管延伸到水面之上,为层流输出流提供明显的非侵入性保护路径。
