  • Patent number: 11710963
    Abstract: A power conditioning system (PCS) includes: a grid blackout determiner, a voltage controller, and a processor electrically connected to the grid blackout determiner and the voltage controller. The processor is configured to identify a state of a grid as a blackout state or an unstable state based on at least one of an amplitude or a frequency of a voltage of the grid that is detected by the grid blackout determiner, control the voltage controller to adjust, based on the identified state of the grid being the blackout state or the unstable state, load voltage input to the voltage controller to be equal to a command voltage, and adjust, based on the identified state of the grid being the blackout state or the unstable state, a first frequency of the detected voltage of the grid to a second frequency that is different from the first frequency.

  • Patent number: 11607157
    Abstract: Provided is a flexible transcutaneous oxygen partial pressure sensor which may be closely attached to a skin, be used repeatedly for a long time, and have a highly reliable measurement value. The flexible transcutaneous oxygen partial pressure sensor of the present disclosure includes: an oxygen sensing film having one surface in contact with a skin; a light detecting portion including a light emitting portion which is positioned above a surface opposite to the one surface of the oxygen sensing film and includes a micro-light emitting diode (LED (?-LED)), and a light-receiving portion which includes an organic-photodiode (OPD); and a heater portion positioned between the oxygen sensing film and the light detecting portion, and supplying thermal energy to the skin in contact with the oxygen sensing film.

  • Patent number: 9365427
    Abstract: A method for purifying carbon nanotubes (CNTs) includes heating the CNTs including metallic impurities and metallic oxide impurities; reducing the metallic oxide impurities by passing a reducing gas through the CNTs; removing the metallic impurities and the reduced metallic oxide impurities by passing a liquid halide through the CNTs using a carrier gas; and cooling the CNTs. Therefore, by simply passing liquid chloroform through CNTs using a carrier gas, a method for purifying CNTs can be provided so as to simply, economically, and effectively remove metallic impurities from the CNTs in a short time through one step. In addition, the purification effect can be further improved by removing the metallic oxide impurities as well as the metallic impurities through the reducing step. In addition, it is possible to improve the purification effect by further performing a step of removing a halogen or an acid-treatment purification step.
