  • Publication number: 20250042393
    Abstract: A system for controlling lateral positioning in a host vehicle includes a controller having a processor and tangible, non-transitory memory. The host vehicle is located on a host lane defined by a host lane center. The controller is adapted to determine if a first and second enabling condition are met. The first enabling condition is met when the host vehicle is travelling on a non-divided road having no physical barrier separating respective traffic lanes travelling in opposing directions. The second enabling condition is met when the host lane is an inner most lane adjacent to an opposing traffic lane. When the first and second enabling conditions are both met, the controller is adapted to determine a non-divided road offset relative to the host lane center in real-time. Operation of the vehicle is controlled based in part on a magnitude, and a direction of the non-divided road offset.

  • Patent number: 12152977
    Abstract: A method for combined characterization of pore structure includes steps as follows. Firstly, CO2, N2 and high-pressure mercury intrusion porosimetry characterization curves are plotted based on actual measurement data, then, average values of the overlapping range of the CO2 and N2 characterization curves are calculated, and a function yi?=ƒ(x) is fitted. Each pore volume yi? corresponding to each pore diameter xi is calculated, and a curve is plotted with xi as a horizontal coordinate and yi? as a vertical coordinate, thereby obtaining a characterization curve of the overlapping range between CO2 and N2 adsorptions. The same data processing is used to process the overlapping range data of the N2 and high-pressure mercury intrusion porosimetry characterization curves, to obtain the characterization curve between them. The characterization curves are spliced with the original CO2, N2, and high-pressure mercury intrusion porosimetry characterization curves to obtain a combined characterization curve.

  • Publication number: 20200046339
    Abstract: Disclosed is a three-in-one suturing device for closing a cannula hole, belonging to the field of medical instruments and solving the troublesome suturing problem in laparoscopic surgery. The cannula hole is closed in a quick, effective and safe manner by means of the cooperation of a pull hook, a suture needle and a fishbone thread. In the entire threading process, the needle tip only needs to penetrate the human body without going out of the human body; therefore, the operation difficulty and time of the cannula hole suturing surgery are reduced; and the fishbone thread is used to suture the cannula hole from the bottom of the suture portion.
