  • Publication number: 20240128915
    Abstract: Disclosed is a motor driving apparatus including: a motor; an inverter including a switching element for driving the motor; a controller for controlling the switching element; a resolver including an excitation winding and a detection winding; and a resolver chip applying an excitation signal to the excitation winding by inputting a periodic signal from the controller, and receiving a feedback signal from the detection winding, wherein the resolver chip determines the number of rotations of the motor based on a change in a pulse width of a detection signal resulting from a comparison between a voltage of the feedback signal and a preset voltage, and output a signal to the inverter for setting an inertial driving control mode according to the number of rotations of the motor in a failure state of the controller.

  • Publication number: 20240069524
    Abstract: Disclosed is an apparatus for excitation signal generation for a resolver. The apparatus includes a sine wave generator that generates a sine wave based on a square wave, an amplifier that amplifies the sine wave, a differential signal generator that converts, into a differential signal, the amplified sine wave, a driver that inputs the differential signal to a coil, and a processor that generates an excitation signal by increasing a voltage of the sine wave from a start voltage to a target voltage through at least one of the sine wave generator and the amplifier based on a transient current that flows into the coil in a transient response interval.

  • Publication number: 20220154278
    Abstract: CPNE7 protein or a nucleotide encoding for CPNE7 protein, or compositions containing the CPNE7 or the nucleotide and their uses are disclosed. The protein, nucleotide, or composition is useful for preventing or treating fatty liver disease. The CPEN7 protein regulates the expression of the SREBF1 (SREBP1) gene or a gene encoding the same. The composition can be a pharmaceutical composition or a quasi-drug composition, a health functional food, or a dietary supplement, which is suitable for preventing or alleviating fatty liver disease.

  • Publication number: 20210140979
    Abstract: A method of diagnosing a periodontal condition using a protein showing a concentration difference between periodontal tissue in a normal condition and an abnormal condition from a subject's saliva is provided. According to this non-invasive method, the patient himself is able to check the presence of periodontal disease and identify the time to receive a treatment at an early stage, which will allow the patient to save time and cost for the treatment of periodontitis.

  • Publication number: 20120148538
    Abstract: The present invention relates to a composition for hard tissue formation and dentin, or dental pulp regeneration comprising ameloblasts, apical bud cells, or its culture fluid as an active ingredient. The ameloblasts, apical bud cells, or its culture fluid promotes the differentiation of odontoblasts, human dental pulp stem cells and osteoblasts, increases DSPP promoter activity, induces dental pulp regeneration of dental pulp stem cells, and induces hard tissue formation significantly in vivo, so that they can be effectively used for a composition for promoting hard tissue formation and dentin or dental pulp regeneration.
