Jian H. Yu 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: 11307012
    Abstract: An explosive threat mitigation unit (TMU) stands ready to receive a suspected bomb, enclose it, and contain the explosion if one occurs. An operator protects bystanders and surroundings by putting the suspected bomb in a TMU and then closing the TMU. If the bomb goes off, the TMU mitigates the effects of both the blast and the fragments. One variation has a container, a tube, a cap, and a door. The container includes an opening. The tube, arranged in the container, aligns with the opening. The cap slides through the opening and over the tube. The door slides into place to close the opening and enclose the cap within the container.
    Type: Grant

  • Publication number: 20190091768
    Abstract: Rapid additive sintering of materials using electric fields includes a pair of electrodes including a first and second electrode, a power supply operatively connected to the pair of electrodes, and an area in between the pair of electrodes that holds a material. The first electrode is configured for flash sintering the material. The first electrode may be movable and may include a stylus. The material may include powder and may include any of metallic and ceramic material. Multiple layers of materials may be flash sintered by the first electrode. The first electrode may generate an electric field between the first electrode and the material causes the flash sintering. A nozzle may supply the material at variable speeds. The first electrode may be configured to move at variable speeds and in variable directions. The flash sintering may occur at an electric field between 10-50000 V/cm and an electric current between 0-30A.
