  • Publication number: 20230223578
    Abstract: Proposed are a system and a method for pressurizing an all-solid-state secondary battery at high temperature. More particularly, proposed are a system and a method for pressurizing an all-solid-state secondary battery at high temperature, in which a pre-process of high-temperature pressurization for maximizing a contact interface between a solid electrolyte and an active material and minimizing interfacial resistance is automated in such a manner that the fed secondary battery is automatically packed through a vacuum sealing unit and then pressurized at high temperature, thereby shortening a tact time and thus increasing process efficiency.

  • Publication number: 20230205134
    Abstract: Provided are a webserver-based video content production system and method for printing a holographic stereogram photo. According to the webserver-based video content production system and method, an encoding process is performed on image data under a web environment to prevent data loss in a network communication process, and then the encoded image data is transmitted to a webserver. The webserver decodes the encoded image data and performs a second-half task (postprocessing) on the decoded image data using deep learning such that a high-quality hologram photo can be printed within a relatively short time without any unnecessary process.
