摘要： A DES permutation is presented that has minimal crossovers between the DES 64-bit structure and 32-bit data structures, allows for efficient data transfers via a 32-bit data bus. Every other bit location in the DES 64-bit data structure is mapped to a contiguous bit location in the 32-bit data structure, in a sequential order. The sequential mapping to contiguous bit locations minimizes potential crossovers that are area inefficient, and allows for encoding algorithms that effect the mapping by using incrementing or shifting operators only.

摘要： The invention relates to a process for the production of optically selective surfaces for use in solar collectors, having a predetermined ratio of absorbance .alpha..sub.s to emmitance .epsilon. of at least 10, which comprises effecting an anodic oxidation of copper, or copper applied to any substrate metal, in an alkaline bath at an elevated temperature between 50.degree. and 85.degree. C., preferably 70.degree. to 85.degree. C., and at a current density of above 1 mA/cm.sup.2 and up to 40 mA/cm.sup.2 until an increase of resistance is experienced. Substrate metals may be copper, copper plated steel, copper plated galvanized iron, copper plated nickel, nickel plated steel to which a layer of copper is applied, and the like.

摘要： A redundant inertial measuring system includes three strapdown platforms each having two inertial sensors. The sensitive axes of the sensors are discretely disposed relative to the faces of a dodecahedron. The sensors and their associated electronics are physically and electrically separated from each other within each of the platforms.
