    • A phononic material and a method of using a phononic material for use in interacting with a fluid or solid flow are provided. The phononic material includes an interface surface and a subsurface feature. The interface surface is adapted to move in response to a pressure associated with at least one wave in a flow exerted on the interface surface. The subsurface feature extends from the interface surface. The subsurface feature comprises a phononic crystal or locally resonant metamaterial adapted to receive the at least one wave having the at least one frequency based upon the pressure from the flow via the interface surface and alter the phase of the at least one wave. The interface surface is adapted to vibrate at a frequency, phase and amplitude in response to the manipulated/altered phase of the at least one wave.

    • A pinch valve is provided which includes an outer housing into which lower and upper elements are positioned. A flexible, tubular shaped hose, duct, or similar conduit or line to be used under pressure is inserted into and maintained between a support section of the lower pinch element and a support section of the upper pinch element. A resilient spring located between the lower pinch element and the bottom surface of the outer housing compresses the flexible line into a closed position, in order to maintain an effective and leak proof closure of the line. When it is desired that the pressurized line be opened and fluid in the line be permitted to flow, an actuating button located atop the outer housing is pressed. The resulting pressure acts against the compressive force of this spring, causing the lower pinch element to move down within the housing, thereby opening the flexible line to permit fluid flow. When pressure is removed from the actuating button, the compressive force of the spring once again compels the lower pinch element upward, thereby closing the line.
    • 提供夹管阀,该夹管阀包括外部壳体,下部元件和上部元件位于所述外部壳体中。 将要在压力下使用的柔性的管状形状的软管,导管或类似导管或管线插入并保持在下夹紧元件的支撑部分和上夹紧元件的支撑部分之间。 位于下部夹紧元件和外部壳体的底部表面之间的弹性弹簧将柔性管线压缩到关闭位置,以便保持线路的有效且防漏的闭合。 当期望打开加压管路并允许管路中的流体流动时,按压位于外壳顶上的致动按钮。 所产生的压力克服该弹簧的压缩力而作用,导致下部夹紧元件在壳体内向下移动,由此打开柔性管线以允许流体流动。 当从致动按钮上移除压力时,弹簧的压缩力再次迫使下夹紧件向上,从而关闭线。
