Abstract: A speech coding system of the code excited linear prediction (CELP) type comprises means (24,26) for filtering digitised speech samples to form perceptually weighted speech samples. Entries in a one-dimensional codebook (110) comprising frame length sequences are filtered in a perceptually weighted synthesis filter (28) to form a one-dimensional filtered codebook (38). The filtered codebook entries are compared with the perceptually weighted speech signals to obtain a codebook index which gives the minimum perceptually weighted error when the speech is resynthesised. Using a one-dimensional codebook (110) reduces the amount of computation which is required compared to using a two-dimensional codebook.

Abstract: Compressed air is purified in apparatus 4 and passed through heat exchanger 6 in which it is reduced in temperature ready for rectification in a double column comprising a higher pressure rectification column 10 and a lower pressure rectification column 12 which are linked by a condenser-reboiler 14. The air is separated in the column 10 into oxygen-rich and nitrogen fractions. The oxygen-rich fraction is separated in the lower pressure column 12 into an oxygen and a lower pressure nitrogen product. Liquid nitrogen from the higher pressure column 10 is used as reflux in the lower pressure column 12, and a gaseous nitrogen stream is withdrawn from the column 10 as higher pressure nitrogen product. In order to compensate for the resulting loss of reflux in the column 12, a part of the lower pressure nitrogen product stream is compressed in compressor 38, cooled by passage through heat exchanger 6, and condensed in condenser 40. The resulting condensate provides additional reflux in the column 12. This arrangement makes possible enhanced power recovery from nitrogen produced in an air separation plant providing an oxygen product at an elevated pressure.

Abstract: A RISC computer is specially adapted in its hardware and operating procedures for operating systems based upon sets of logical statements utilizing fuzzy logic procedures. The computer may operate either stand-alone or embedded in a host computer, and supplies system control signals derived from measurements of system operating conditions and operating knowledge expressed in fuzzy logic form. A core processor of the computer performs logical evaluations and mathematical manipulations, and performs other control and memory management functions. A key feature of the logical evaluation hardware approach is the evaluation of logical conclusions by their areas and moments determined prior to program execution, permitting much faster computation of command signals than previously possible. Communication to the controlled system or a host computer is through an arbiter that manages the data flow in conjunction with a data memory.
