  • Apparatus and method of analyzing developed impact marks, and computer program for executing the method
    Patent number: 11995887
    Abstract: A developed impact mark analysis apparatus includes: an image acquisition unit configured to obtain at least one first image by photographing impact marks that are developed, and to obtain a second image of impact marks at a crime scene that are developed from evidence at the crime scene; an outliner configured to outline the at least one first image to obtain at least one first outline image, and to outline the second image to obtain a second outline image; a database configured to store the first outline image corresponding to related tool characteristic information; a matching unit configured to search the database for the first outline image determined to be similar to the second outline image and match them with each other; a display unit; and a user input unit.

  • Apparatus for producing UOpowder
    Patent number: 8388895
    Abstract: In an apparatus for producing U3O8 powder, the apparatus has an oxidation reactor including an interior space, a scrap box loaded with UO2 sintered pellets to be oxidized and introduced into the interior space of the oxidation reactor, an impact generating unit applying an impact to the scrap box to dissipate heat generated by the oxidation of the UO2 sintered pellets in the oxidation reactor, and a control unit controlling an oxidation process. The apparatus for producing U3O8 powder allows the heat generated by the oxidation of the UO2 sintered pellets in the oxidation reactor to be uniformly dissipated by the impact generating unit, thus producing U3O8 powder having a larger specific surface area which can be used to obtain a sintered UO2 pellet with a larger and more stable grain size of increased quality.
