Patents by Inventor Satya Ajjarapu

Satya Ajjarapu 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: 20220057686
    Abstract: The present invention provides for an electroactive device having a first conductive layer, a second conductive layer, and one or more electroactive layers sandwiched between the first and second conductive layers. One or more adjacent layers of the electroactive device may include a physical separation between a first portion and a second portion of the adjacent layers, the physical separation defining a respective tapered sidewall of each of the first and second portions. The one or more adjacent layers may include one of the first and second conductive layers. The remaining layers of the electroactive device may be formed over the physical separation of the one or more adjacent layers. The remaining layers may include the other of the first and second conductive layers.

  • Publication number: 20200362274
    Abstract: Several of the films that comprise various energy producing or control devices, for example, electrochromic devices, lithium batteries, and photovoltaic cells, are sensitive to moisture in some way. They may be especially vulnerable to moisture at particular stages during their fabrication. It may also be highly desirable during fabrication to be able to wash particulates from the surface. The particulates may be generated some aspect of the fabrication process, or they may arise from the environment in which the fabrication takes place. This invention shows ways to remove said particles from the surface without incurring the damage associated with typical washing processes, resulting in higher manufacturing yields and better device performance.
