Abstract: Conventional AND vectors are compared to corresponding input vectors of the same length as part of the logic processing associated with the finite state machine. AND vectors having a single set bit are translated into AND index vectors in which the bit position of the single set bit is encoded. AND index vectors are also identified by an index flag. The encoded bit position is utilized to identify the corresponding bit position in the input vector to perform a TRUE/FALSE test to determine an overall TRUE or FALSE indication. This technique avoids a bit by bit comparison for AND vectors having a single set bit.

Abstract: Beryllium to metal seals are produced by forming on a beryllium surface by cathode sputtering a first metal layer from a group of metals including tantalum, niobium, zirconium, hafnium, titanium or vanadium, an intermediate cathode sputtered layer of a refractory metal and outer layer of a readily brazable metal and soldering the readily brazable layer to another metallic body.
