    • An antenna array comprised of a fractile array having a plurality of antenna elements uniformly distributed along Peano-Gosper curve. An antenna array comprised of an array having an irregular boundary contour. The irregular boundary contour comprises a plane tiled by a plurality of fractiles and the plurality of fractiles covers the plane without any gaps or overlaps. A method for generating an antenna array having improved broadband performance. A plane is tiled with a plurality of non-uniform shaped unit cells of an antenna array. The non-uniform shape of the unit cells and the tiling of said unit cells are then optimized. A method for rapidly forming a radiation pattern of a fractile array and a PeanoGosper fractile array. A pattern multiplication for fractile arrays is employed wherein a product formulation is derived for the radiation pattern of a fractile array for a desired stage of growth. The pattern multiplication for fractile arrays is recursively applied to construct higher order fractile arrays. An antenna array is then formed based on the results of the recursive procedure.
    • 天线阵列由具有沿Peano-Gosper曲线均匀分布的多个天线元件的分数阵列组成。 由具有不规则边界轮廓的阵列组成的天线阵列。 不规则的边界轮廓包括由多个分段平铺的平面,并且多个分割体覆盖平面而没有任何间隙或重叠。 一种用于产生具有改进的宽带性能的天线阵列的方法。 平面与多个天线阵列的不均匀形状的单元电池相平铺。 然后优化单元电池的不均匀形状和所述单元电池的平铺。 一种用于快速形成分数阵列和PeanoGosper分形阵列的辐射图的方法。 采用分数阵列的图案乘法,其中产生用于期望生长阶段的分数阵列的辐射图的产品配方。 分数数组的模式乘法被递归地应用于构造高阶分数数组。 然后基于递归过程的结果形成天线阵列。

    • In a system and method for transmitting data bits over a transmission channel, data bits are arranged into a plurality of matrices, each matrix having a plurality of blocks, and the matrices are arranged into a cube having first and second dimensions, wherein the first dimension relates to one of the matrices and the second dimension relates to multiple matrices. A set of check bits is generated (1904) for each of the blocks in the plurality of matrices. Each set of check bits includes a first and second check bit, wherein the first check bit relates to the first dimension of the cube and the second check bit relates to the second dimension of the cube. One or more of the cubes are transmitted across the channel and received at a decoder (1902a). The decoder detects and corrects one or more errors in data bits of received cubes in accordance with the check bits.

    • A label relating to a service accessible on a web server (110) is determined using a web server (106), is returned to the first user (104) and may be included in a permission, which can then be delegated (108) to enable access to the service. In some cases, upon transmitting the label via a messaging system, information based on the label and the public key of the recipient is automatically stored on the web server. In other cases, a first permission, including a label related to a service, is maintained at a web server. A user is provided access to the first permission upon his authenticating to the web server and is provided a permission to access the service. In still other cases, a permission is included in a single electronic message that is to be sent to multiple recipients via a messaging system. The message is automatically processed by the web server upon its receipt from a recipient seeking access to the service.
