    • The present invention provides a display system that eliminates the need for a cabinet enclosure and allows for the projection of images towards an image screen at greater angles of incidence than previously achievable while maintaining image quality. Embodiments of the present invention reduce the emission of ambient or extraneous light from the image screen through the use of the refracting properties of the screen. The display system may utilize a transparent or translucent screen support that gives the appearance of a floating display. The image screen is specially configured through the use of a double lenticular lens such as a Fresnel lens using asymmetric prisms combined with a substantially opaque layer and a diffusing layer.
    • 本发明提供了一种显示系统,其消除了对机柜外壳的需要,并且允许以更先进的入射角以更大的入射角将图像投影到图像屏幕,同时保持图像质量。 本发明的实施例通过使用屏幕的折射特性来减少来自图像屏幕的环境光或外来光的发射。 显示系统可以利用透明或半透明的屏幕支持,其给出浮动显示器的外观。 图像屏幕是通过使用诸如菲涅尔透镜的双透镜状透镜而特别配置的,其使用与基本上不透明的层和漫射层结合的不对称棱镜。

    • A PEM fuel cell power plant includes fuel cells, each of which has a cathode reactant flow field plate which is substantially impermeable to fluids, a coolant source, and a fluid permeable anode reactant flow field plate adjacent to said coolant source. The anode reactant flow field plates pass coolant from the coolant sources into the cells where the coolant is evaporated to cool the cells. The cathode flow field plates prevent reactant crossover between adjacent cells. By providing a single permeable plate for each cell in the power plant the amount of coolant present in the power plant at shut down is limited to a degree which does not require adjunct coolant purging components to remove coolant from the plates when the power plant is shut down during freezing ambient conditions. Thus the amount of residual frozen coolant in the power plant that forms in the plates during shut down in such freezing conditions will be limited. The power plant can thus be restarted and brought up to full operating power levels quickly due to the reduced amount of frozen coolant that must be melted during startup. Pressure in the coolant source is preferably greater than ambient pressure, and pressure in the anode reactant flow field is greater than the pressure in the coolant source so as to prevent the coolant from flooding the cells. The power plant is well suited for use in powering vehicles.
    • PEM燃料电池动力装置包括燃料电池,其中每个燃料电池具有基本上不可渗透流体的阴极反应物流场板,冷却剂源以及与所述冷却剂源相邻的流体可渗透阳极反应物流场板。 阳极反应物流场板将来自冷却剂源的冷却剂传递到冷却剂被蒸发以冷却电池的电池中。 阴极流场板防止相邻电池之间的反应物交叉。 通过为发电厂中的每个电池提供单个可渗透板,关闭发电厂时存在的冷却剂量限制在不需要附加冷却剂吹扫组件以在发电厂关闭时从板去除冷却剂的程度 在冻结环境条件下下降。 因此,在这种冷冻条件下关闭期间在板中形成的发电厂中残留的冷冻冷却剂的量将受到限制。 由于在启动过程中必须熔化的冷冻冷却剂量减少,因此可以重新启动发电厂并使其快速达到全功率水平。 冷却剂源中的压力优选大于环境压力,并且阳极反应物流场中的压力大于冷却剂源中的压力,以便防止冷却剂淹没单元。 该发电厂非常适合用于动力车辆。
