    • An optical waveguide (106) with directional microprisms (116) and multidirectional light sources (110)(112) are provided for providing overlapping morphing images (104) and information (102) on a display (124) of a touch screen mobile phone or other electronic device (100). Microprisms can be patterned in the shape of a particular design, character, icon or other image. The microprisms can include: first microprisms (118) sensitive to light propagating in only one direction; second microprisms (120) sensitive to light propagating in a different direction, and a third microprisms (122) sensitive to light propagation in multiple directions. When light is directed into the waveguide (106) in a direction to which a portion of the microprisms (116) are sensitive, a fraction of that light will be directed upward and out of the waveguide (106) by those microprisms sensitive to light propagated in that direction. Controlling, switching or selectively activating the light sources (110)(112) results in different images (104) which are displayed and illuminated on the display (124) of the electronic device (100).
    • 提供了具有定向微棱镜(116)和多向光源(110)(112)的光波导(106),用于在触摸屏移动电话的显示器(124)上提供重叠变形图像(104)和信息(102),或 其他电子设备(100)。 微棱镜可以以特定设计,字符,图标或其他图像的形状进行图案化。 微棱镜可以包括:仅对一个方向传播的光敏感的第一微棱镜(118) 对沿不同方向传播的光敏感的第二微棱镜(120)和对多个方向的光传播敏感的第三微棱镜(122)。 当光沿着微棱镜(116)的一部分敏感的方向被引导到波导(106)中时,该光的一部分将通过对光传播敏感的那些微棱镜而被引导向上并离开波导(106) 在这个方向。 控制,切换或选择性地激活光源(110)(112)导致在电子设备(100)的显示器(124)上显示和照亮的不同图像(104)。

    • An exemplary device and method for microfluidic transport is disclosed as providing inter alia a passive check valve (100), a fluid inlet channel (210), a fluid outlet channel (220) and a pumping cavity (240). The fluid inlet channel (210) is generally configured to flow a fluid through the check valve (100). The check valve (100) generally provides substantially passive means for preventing or otherwise decreasing the incidence of purged outlet fluid re-entering either the pumping cavity (240) or the fluid inlet channel (210). Accordingly, the reduction of backflow generally tends to enhance overall pumping performance and efficiency. Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve micropump operation in any microfluidic application. Exemplary embodiments of the present invention representatively provide for substantially self-priming micropumps that may be readily integrated with, for example, existing portable ceramic technologies for the improvement of device package form factors, weights and other manufacturing and/or device performance metrics.
    • 公开了一种用于微流体输送的示例性装置和方法,其特别是提供被动止回阀(100),流体入口通道(210),流体出口通道(220)和泵送腔(240)。 流体入口通道(210)通常构造成使流体流过止回阀(100)。 止回阀(100)通常提供基本上被动的装置,用于防止或以其他方式减少重新进入泵送腔(240)或流体入口通道(210)的净化出口流体的入射。 因此,回流的减少通常倾向于提高整体泵送性能和效率。 公开的特征和规格可以被不同地控制,适应或以其他方式任意地修改以改善任何微流体应用中的微泵操作。 本发明的示例性实施例代表性地提供了可以容易地与例如现有便携式陶瓷技术集成以用于改进装置包装形状因子,重量和其它制造和/或装置性能度量的基本上自吸的微型泵。
