    摘要： A soft, flexible foam characterized in having (i) a hardness, IFD 25% value, of at most 29 lbs/50 in.sup.2, as determined in accordance with Test B.sub.1 of ASTM D 3574 and (ii) a density of about 0.9 to 3.0. pounds per cubic foot is disclosed. Accordingly, the foam is prepared by reacting an organic polyisocyanate with a polyol in the presence of a catalyst and water and a compound conforming to ##STR1## where A is selected from among H, COOH, NH.sub.2, and OH, M is a counter ion, andwhere n, x and m are selected such that said compound has a number average molecular weight of about 500 to 20,000, a functionality of 0 to 10 and a sulfonate concentration of about 0.1 to 30 percent by weight.

    摘要： A self-learning and/or self-adjusting communication controller and/or optimizer uses operational data collected from a communication system to adjust operation of the communication system to changing operational, environmental, etc. conditions and, in some embodiments, to customize operation of the communication system's lines and components so that their performance can be controlled, improved and/or optimized. In various embodiments, operational parameters and/or rules are established and/or adjusted based on information obtained from the system concerning the system's operation; information regarding margins used by a DSL system and code violation counts reported by the DSL system are used to set margin levels for one or more line sets (each line set including an individual line, a group of lines, a binder, etc.) and/or other users and/or components of the DSL system; and, the controller and/or optimizer forces a small number of test lines into as yet unexperienced and/or unimplemented operational conditions so that new knowledge can be obtained.

    摘要： A thermoplastic molding composition is disclosed comprising (i) a thermoplastic polyurethane resin and (ii) an ionomer. The ionomer is a salt of a copolymer, having a weight average molecular weight of 1,000 to 200,000, of 70 to 99 percent olefin and about 1 to 30 percent of alpha, beta-ethylenically unsaturated carboxylic acid. At least some of said carboxylic acid is neutralized by a monovalent counter-ion. The composition is characterized by its improved processability.
