  • Patent number: 7377948
    Abstract: Methods of the present invention are provided for forming a plurality of electrochemical cell layers, each cell layer generally including a pair of electrodes and a separator electrically insulating the pair of electrodes. Cells of a desired size are formed by slicing the laminar sheet through both opposing major surfaces. In certain embodiments, individual cells are defined by fill regions, filled with removable substances. Thus, when the cells are sliced, individual cells and in certain embodiments current collectors or conductors are exposed with minimal or no further processing. In other embodiments, fluid access channels or porous layers are filled with removable substances. Thus, when the cells are sliced, structural support is provided for the intended void regions.

  • Patent number: 7034909
    Abstract: Disclosed are super broadband circularly polarizing film materials and novels methods of fabricating and using the same. The circularly polarizing materials are made from a film of material, such as a CLC polymer having a cholesteric order, in which a liquid crystal material, such as a nematic liquid crystal material, is distributed in a non-linear fashion across the thickness of the film in a plurality of liquid crystal-rich and liquid crystal-depleted sites in the CLC polymer. The pitch of the helices of the CLC molecules in the polyermized CLC material varies in a non-linear (e.g. exponential) manner along the depth dimension (i.e. transverse to the surface) thereof. The resulting circularly polarizing materials have reflection and transmission characteristics over bands of operation approaching 2000 nm. Depending on the final spiral structure of the materials utilized, the CLC circularly polarizing materials reflect either left-handed or right-handed circularly polarized light.
