Patents by Inventor Mijia Yang

Mijia Yang 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).

  • Patent number: 11984846
    Abstract: A power conversion circuit is used in a solar array suitable for, e.g., roadside adjacent installation. The power conversion circuit includes an inverter with a first stage electrically coupled to one or more solar panels. A third stage of the circuit has a DC to AC converter that provides less than a 50 VAC load voltage to a load, and a second stage that is coupled between the first and third stages and provides an isolated electrical power coupling therebetween. A sync interface communicatively couples a controller to other controllers dedicated to one or more other respective inverters of the solar array via a sync signal. The controllers synchronize the third stages of the inverters via the sync signal. The third stages of the inverters are coupled in series to provide a load output voltage.

  • Patent number: 8141317
    Abstract: The present invention relates generally to improved lattice structures that can be used in, for example, blast resistant armor appliqués. In another embodiment, the present invention relates to methods for designing improved lattice structures where the lattice structures are bistable bond lattice structures. In still another embodiment, the present invention relates to lattice structures that employ asymmetric waiting links and unequal lengths of main links.
