摘要： The invention relates to a composition comprising a modified, random copolyetherester containing a modified, random polybutylene terephthalate copolymer block that is derived from a polyethylene terephthalate component selected from the group consisting of polyethylene terephthalate and polyethylene terephthalate copolymers and combinations thereof; and contains at least one residue derived from the polyethylene terephthalate component; and a polyalkylene oxide copolymer block that contains polyalkylene oxide and at least one residue derived from the polyethylene terephthalate component. The composition has a modulus of elasticity that is at least 80%, as compared to the modulus of elasticity of a copolyetherester derived from (1) polybutylene terephthalate derived from a monomer component selected from the group consisting of terephthalic acid, isophthalic acid, alkyl esters of terephthalic acid, hydroxyalkyl esters of terephthalic acid, alkyl esters of isophthalic acid, 1,4-butanediol, (2) polyalkylene oxide glycol, and (3) combinations thereof.

摘要： A system for converting digital signals into analog signals using sigma-delta modulation and includes a signed thermometer encoder for converting a plurality of signed binary data received at the encoder into a plurality of signed thermometer data and a rotational dynamic element matching (DEM) arrangement for receiving the plurality of signed binary data and the plurality of signed thermometer data. The rotational DEM arrangement further includes a first barrel shifter for receiving a positive thermometer data at a cycle, the first barrel shifter having a first pointer indicating a starting position of next positive thermometer data, and a second barrel shifter for receiving a negative thermometer data at a cycle, the second shifter having a second pointer indicating a starting position of next negative thermometer data, wherein the first pointer is circularly shifted as a function of positive binary data and the second pointer is circularly shifted as a function of negative binary data.
