Title: Qing Fu Dong: Innovator in Data Deduplication and 3D Printing Technologies.
Introduction
Qing Fu Dong is a notable inventor based in Beijing, China. He has made significant contributions to the fields of data deduplication and 3D printing technologies. With a total of 2 patents, his work showcases innovative approaches to modern technological challenges.
Latest Patents
One of his latest patents is titled "Dual-mode deduplication based on backup history." This invention discloses methods, systems, and processes to perform dual-mode deduplication based on backup history. A fingerprint of a data segment of a data stream is calculated, and a determination is made as to whether the fingerprint of the data segment matches a corresponding fingerprint in a cache. If the fingerprint matches, another fingerprint of a subsequent data segment is calculated. If it does not match, a segment boundary of the data stream is calculated based on a hash value, leading to further calculations of segment boundaries and fingerprints.
Another significant patent is the "3D print apparatus and method utilizing friction stir welding." This invention introduces a 3D printing apparatus that includes a material feeding mechanism, a control mechanism, a friction stir welding (FSW) mechanism, and a rotation drive mechanism. The method involves several steps, including starting the control mechanism, feeding filling material, and printing a 3D product using the FSW mechanism. This invention achieves additive manufacturing with high efficiency, low energy consumption, and broad applicability.
