  • Patent number: 10486758
    Abstract: A drop axle lift kit for a golf cart includes a base plate. Each support arm of a pair of support arms is positioned proximate a respective lateral side of the base plate. Each support plate of a pair of support plates is mounted to a respective support arm of the pair of support arms at a distal end of the respective support arm. A pair of rod end bearings is configured to rotatably support a front steering spindle of the golf cart such that the front steering spindle of the golf cart is rotatable about an axis. The pair of rod end bearings is mounted to one of the pair of support plates such that an angle defined between the axis and vertical is adjustable in order to change a canter of a wheel on the front steering spindle of the golf cart.

  • Patent number: 10393882
    Abstract: Example methods disclosed herein include accessing carrier phase measurements and code measurements obtained for a plurality of satellite signals of a global navigation satellite system. Disclosed example methods also include determining an initial set of floating-point ambiguities based on the measurements, the initial set of floating-point ambiguities including inter-frequency bias (IFB). Disclosed example methods further include performing a least squares search process based on the initial set of floating-point ambiguities to determine a set of integer ambiguities and an estimate of the IFB. In some examples, an additional (e.g., wide-lane) filter is used to realize a combination of carrier phase and code IFB. In some examples, IFB estimation is further realized by determining a median of IFB estimates over a window time. In some examples, the resulting IFB estimate and the set of integer ambiguities are used to estimate a position of a receiver, determine a satellite correction signal, etc.

  • Patent number: 10338232
    Abstract: A satellite corrections generation system receives reference receiver measurement information from a plurality of reference receivers at established locations. In accordance with the received reference receiver measurement information, and established locations of the reference receivers, the system determines wide-lane navigation solutions for the plurality of reference receivers.

  • Patent number: 10023624
    Abstract: Recombinant Fc fusion proteins of human follicle-stimulating hormone (hFSH) with in vivo biological activities comparable to those of human follicle-stimulating hormone are disclosed. A recombinant hFSH-Fc fusion protein comprises ? subunit of hFSH (hFSH ?), CTP, ? subunit of hFSH (hFSH ?), a flexible peptide linker, and human IgG2 Fc variant (vIgG2Fc). A method is also disclosed to make such fusion proteins at good expression levels. These recombinant hFSH-Fc fusion proteins of the present disclosure exhibit sufficient biological activities and prolonged plasma half-lives, leading to improved pharmacokinetics and pharmacodynamics. Thus, a lower dosage may be used and/or better or different therapeutic efficacies with less side effects may be achieved. A method for the application of the recombinant hFSH-Fc fusion proteins in the treatment and/or prevention of human infertility is also disclosed.
