A method and system for securely decrypting and decoding a digital signal is disclosed. A color histogram of the image is extracted from the image, the extraction of the color histogram including performing one-dimensional sampling of pixels comprising the image in each of a first dimension of a color space, a second dimension of the color space, and a third dimension of the color space. The software module server responds with an instruction set for installing the software module and the software module itself. A latch locks the handle assembly in the home position. The physical barrier layer comprises zirconia or hafnia stabilized with an oxide of a metal selected from the group consisting of magnesium, calcium, scandium, yttrium, and lanthanide metals; and a low CTE oxide selected from the group consisting of niobia and tantala; and mixtures thereof. The graphite material in the negative electrode mixture layer is arranged such that the plane 85A of at least 50 mass % of the graphite material is perpendicular to the surface of the negative electrode current collector and parallel to the longitudinal direction of the elongated negative electrode current collector.
