  • Patent number: 12005901
    Abstract: A method of controlling a brake lamp of a vehicle including an electric motor as a power source includes determining whether gear shifting is required and whether there is a forward section with a suddenly changing slope when regenerative braking is performed through the electric motor without manipulation of an accelerator pedal or a brake pedal, delaying the gear shifting until the gear shifting exceeds a gear-shifting limit when the gear shifting is required and when there is the forward section with the suddenly changing slope, calculating acceleration based on regenerative braking torque while the gear shifting is delayed, and controlling the brake lamp based on the calculated acceleration.

  • Publication number: 20240175394
    Abstract: A combined power generation system includes a gas turbine including a compressor configured to compress air, a combustor configured to mix the compressed air from the compressor and fuel and combust a mixture of the compressed air and fuel, and a turbine section in which rotational power is obtained by combustion gases generated by the combustor. The system also includes a heat recovery steam generator (HRSG) in which steam is generated by heat of exhaust gases from the gas turbine, and a steam turbine driven by the steam generated by the HRSG, wherein the HRSG includes a plurality of heat exchangers provided to cool the compressed air by heat exchange between the compressed air and the exhaust gases.

  • Patent number: 11946031
    Abstract: Provided is yarn for a cell culture scaffold. The yarn for a cell culture scaffold according to an exemplary embodiment of the present invention includes slitting yarn produced by cutting a compressed nanofiber web to a predetermined width. Accordingly, by creating microenvironments suitable for migration, proliferation and differentiation of cells, cell viability may be enhanced and cells may be three-dimensionally proliferated. In addition, a scaffold according to the present invention has a mechanical strength sufficient for prevention of disruption of the scaffold which occurs during cell culture, such that cells may be stably proliferated. Further, the scaffold according to the present invention uses slitting yarn formed of the compressed nanofiber web, thereby having pores with various sizes, and therefore cell proliferation and cell viability may be enhanced by creation of an extracellular matrix-like environment.

  • Publication number: 20230150911
    Abstract: The present invention relates to a method of manufacturing a diester-based compound, and, more particularly, to a method of manufacturing a diester-based compound, which is performed using a continuous process including a reaction part in which a total of n reaction units spanning from a first reaction unit to an nth reaction unit are connected in series, wherein each of the reaction units includes a reactor, and the method includes: supplying a feed stream including a dicarboxylic acid and an alcohol into the first reactor; esterifying the feed stream to prepare a reaction product; and supplying a lower discharge stream including the reaction product into the reactor of the rear reaction unit. In this case, a conversion rate of the esterification reaction in the first reactor is controlled in a range of 50 to 80%.
