  • Patent number: 6604219
    Abstract: A system and method are disclosed for writing a multilevel data sequence to a storage medium so that a read signal generated by reading the multilevel data sequence from the storage medium will have reduced low frequency content is described. The method includes evaluating the effect of a plurality of candidate merge symbols on an RDS of the read signal. A preferred merge symbol is selected from among the plurality of candidate merge symbols based on the effect of the preferred merge symbol on an RDS of the read signal.

  • Patent number: 6499284
    Abstract: A twisting device having a pair of fiber cakes that are simultaneously hung on a transversely disposed creel, respectively unwind two fiber strands downwardly during the rotation process of the creel. Each of the two fiber strands passes through a strand-cut sensor and then enter a balloon control ring. Through the guide of an oil ring, each of the fiber strands is twisted and then wound around a bobbin driven by a spindle motor. The pair of balloon control rings and the pair of oil rings are simultaneously driven by a ring rail to move upward and downward on the bobbin.

  • Publication number: 20020104304
    Abstract: The present invention proposes a twisting device having enhanced productivity. A pair of fiber cakes are simultaneously hung on a transversely hung creel. The pair of fiber cakes respectively unloosen two fiber strands downwards during the rotation process of the creel. Each of the two fiber strands passes through a strand-cut sensor and then enters a balloon control ring. Through the guide of an oil ring, each of the fiber strands is twisted and then wound around a bobbin driven by a spindle motor. The pair of balloon control rings and the pair of oil rings are simultaneously driven by a ring rail to move upwards and downwards on the bobbin. Therefore, a pair of fiber strands and a pair of bobbins can use the same creel, thereby doubling the productivity per unit time per unit ground area.

  • Patent number: 6377529
    Abstract: A method is disclosed for compensating for intersymbol interference on an optical disc. The method includes measuring an intersymbol linear transfer function. The intersymbol linear transfer function substantially describes a linear portion of the effect of intersymbol interference on an optically detected read signal from an optical disc. A partial response target frequency response is divided by the intersymbol linear transfer function to obtain a linear equalization filter response. A read signal from the optical disc is convolved with the linear equalization filter response. This results in the read signal being equalized and containing a controlled partial-response target intersymbol interference. There is also disclosed a method of compensating utilizing a decision feedback equalizer where the target frequency response is either a partial-response or a zero-forcing response.
