  • Publication number: 20190029148
    Abstract: A vehicle electronic module is provided. The vehicle electronic module has a reduced size and improved productivity by replacing a sensor and an offset unit of an electromagnetic interference (EMI) filter module with a printed circuit board (PCB) winding structure. The electronic module includes a sensor that detects EMI noise of a power line and an offset unit that transmits an offset voltage for removing the EMI noise to the power line. A controller is configured to generate the offset voltage that corresponds to the EMI noise detected by the sensor. Then sensor and the offset unit are formed in a stacked structure of the PCB.

  • Patent number: 9259590
    Abstract: A tube-structured battery to be inserted into a living body is provided. The tube-structured battery includes: a biofuel battery part which generates electric energy by using biofuel in the blood passing through an internal space of the tube structure; a transformer circuit part which adjusts a voltage or current density by using the generated electric energy; and a secondary battery part which is charged with the electric energy by using the adjusted voltage or current density to store the electric energy, wherein the tube-structured battery is inserted into the living body or a blood vessel of the living body.
