  • Publication number: 20220158878
    Abstract: An optimized pulse shaping clock data recovery system is provided that includes a slicer configured to receive a signal and provide an initial set of tentative decisions to a decision feedforward equalizer, where the decision feedforward equalizer provides a fully equalized output signal. The slicer may be incorporated as part of decision feedback equalizer to provide better quality tentative decisions. The clock data recovery system also receives the first output signal that is partially equalized in such a way as to optimally shape it for a clock to sample it at an ideal location by providing an adjustment signal to the analog to digital controller.

  • Patent number: 10792998
    Abstract: Methods and systems are provided for a fuel filler pipe. In one example, a system may include a bracket comprising a bumper physically coupled to a vehicle cross-member. The bumper coming into contact with a fuel filler pipe proximal to the cross-member during some vehicle conditions to block the fuel filler pipe from contacting the cross-member.

  • Publication number: 20130007927
    Abstract: The invention is generally related to compositions and methods related to novel centromere sequences identified in cotton, and resulting recombinant DNA constructs, such as minichromosomes, made using such sequences. Minichromosomes with novel compositions and structures can be used, for example, to transform plant cells that are in turn used to generate minichromosome-harboring plants. The invention is directed to products of such plants, including oil and textiles. The invention is also directed to novel methods for identifying centromere sequences.
