  • Patent number: 11214256
    Abstract: An apparatus for controlling a lane change of a vehicle includes: a sensor to sense an external vehicle, an input device to receive a lane change command from a driver of the vehicle, and a control circuit to be electrically connected with the sensor and the input device. The control circuit may receive the lane change command using the input device, calculate a minimum operation speed for lane change control, and determine whether to accelerate the vehicle based on a distance between a preceding vehicle which is traveling on the same lane as the vehicle and the vehicle, when a driving speed of the vehicle is lower than the minimum operation speed when receiving the lane change command.

  • Publication number: 20100184218
    Abstract: There is provided a method for the isolation and cultivation of mesenchymal stem/progenitor cells from umbilical cord blood, and also to a method for the differentiation of the umbilical cord blood-derived mesenchymal stem/progenitor cells into various mesenchymal tissues. The method include overlaying umbilical cord blood onto Ficoll-Hypaque solution; centrifuging the umbilical cord blood on the Ficoll-Hypaque solution to obtain a mononuclear cell layer; reacting cells obtained by monolayer culture of the mononuclear cells with antibodies to mesenchymal stem/progenitor cell-specific antigens for a predetermined period of incubation time; isolating only cells bound to their corresponding antibodies using a cell sorter; and cultivating the isolated cells, thereby obtaining mesenchymal stem/progenitor cells with high purity and excellent viability.
