Patents by Inventor Yun-Chung Yeh

Yun-Chung Yeh has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20120256712
    Abstract: An incorrect-circuit deactivation device of a magnetic GFCI outlet includes an electromagnetic coil seat, a magneto-conductive core driven by the electromagnetic coil seat to displace, and two magnetic elements located on both sides of the magneto-conductive core. The magneto-conductive core is connected to a first electrical conductive end. The first electrical conductive end is positioned to face a second electrical conductive end. Electric power is supplied when the first electrical conductive end is brought into contact with the second electrical conductive end. The electromagnetic coil seat senses a reverse current to make the magneto-conductive core to displace toward one of the magnetic elements when there is a ground fault, thereby departing the first electrical conductive end from the second electrical conductive end to cut off the electric current.
