    • The present invention provides a system for use with an input signal and a clock signal. The system includes a physical random interval generator, a sampling analog-to-digital converter (ADC), a timing signal generator and a reconstructor. The physical random interval generator can generate a random output signal. The ADC can output a sampled output signal based on the input signal and the random output signal. The timing signal generator can output a timing signal based on the clock signal and the random output signal. The reconstructor can reconstruct an information signal based on the sampled output signal and the timing signal.

    • A valve comprises a valve cartridge, a valve stem and a valve seal. The valve cartridge comprises a generally cylindrical cartridge body, a bore extending longitudinally through the cartridge body, and an outlet passage and intermittent inlet passages extending through a side wall of the cartridge body to intersect the bore. The valve stem comprises an elongate body configured to slide within the bore, and a neck and a seal channel circumscribing the elongate body. The valve seal is seated within the seal channel. The valve stem slides within the bore to move the seal channel past the inlet passages. Portions of the cartridge body between the inlet passages retain the valve seal within the valve channel until the inlet passages are open to the neck. In one embodiment, the inlet passages form a crenelated edge. In another embodiment, the inlet passages form a ported end.
    • 阀包括阀芯,阀杆和阀密封。 阀芯包括大致圆柱形的盒体,纵向延伸通过盒主体的孔,以及延伸穿过盒主体的侧壁以与孔相交的出口通道和间歇入口通道。 阀杆包括构造成在孔内滑动的细长主体,以及颈部和限定细长主体的密封通道。 阀密封件位于密封通道内。 阀杆在孔内滑动以使密封通道移动通过入口通道。 入口通道之间的盒体的部分将阀密封件保持在阀通道内,直到入口通道对颈部开放。 在一个实施例中,入口通道形成楔形边缘。 在另一个实施例中,入口通道形成端口。

    • The present invention discloses 1) a process for photopolymer replication on plastics, and 2) the scale-up step-and-repeat process in photopolymers. High fidelity optical element replication using a master optical element having submicron diffractive pattern feature sizes embossed into a UV curable photopolymer material for step-and-repeat "tiling" replication of the master optical element to create light weight, low cost, large area diffractive optical elements (LADOE). Furthermore, by using a chrome mask to eliminate ridge formation around a single diffractive optic element extremely narrow seams result, thereby increasing the optical fidelity of the resulting LADOE. Accordingly, each LADOE made according to the present invention is characterized by having minimum seam widths between patterns of discrete diffractive optic elements that introduce negligible optical distortion to a viewer.
    • 本发明公开了1)塑料上的光聚合物复制方法,以及2)光聚合物中的放大步进重复工艺。 使用具有亚微米衍射图案特征尺寸的主光学元件的高保真光学元件复制压印到UV可固化光聚合物材料中,用于主光学元件的重复“平铺”复制以产生重量轻,成本低的大面积衍射光学 元素(LADOE)。 此外,通过使用镀铬掩模来消除单个衍射光学元件周围的脊形成,导致非常窄的接缝,从而增加了所得到的LADOE的光学保真度。 因此,根据本发明制造的每个LADOE的特征在于在离散的衍射光学元件的图案之间具有最小的接缝宽度,其向观察者引入可忽略的光学失真。
