  • Multifilament fiber and method of making same
    Patent number: 10738395
    Abstract: A multipolymer fiber comprising a polyester phase formed from at least one polyester resin, present at between about 50 to about 95 percent by weight and a polyamide phase formed from at least one polyamide resin, present at between about 5 to about 50 percent by weight, wherein the polyamide phase is distinct from the polyester phase and comprises a plurality of polyamide fibrils dispersed in the polyester phase, and wherein the polyamide fibrils are separately distinguishable from each other.
    Type: Grant
    Filed: November 4, 2014
    Date of Patent: August 11, 2020
    Assignee: INVISTA North America S.a.r.l.
    Inventors: Subhash Chand, Ali Sayed Fareed

  • Finite-length equalization overmulti-input multi-output channels
    Publication number: 20050009486
    Abstract: A MIMO Decision Feedback Equalizer improves operation of a receiver by cancelling the spatio-temporal interference effects caused by the MIMO channel memory with a set of FIR filters in both the feedforward and the feedback MIMO filters. The coefficients of these FIR filters can be fashioned to provide a variety of controls by the designer.
