Patent number: 8577121Abstract: Disclosed herein is a forged seal imprint checking method which includes a step ST-101 of generating a reference seal imprint from a genuine seal (ST-110) and a step ST-121 of comparing a compared seal imprints with the reference seal imprint to calculate characteristic values of the compared seal imprint with respect to the reference seal imprint (ST-140). According to experimental results, forged seal imprints obtained by seals forged by etching a zinc plate or a resin plate can be recognized and forged seal imprints generated by seals forged through computer copy can be also recognized. Accordingly, an objective basis on which it can be determined whether seal imprints on documents are forged in civil and criminal cases can be provided to prevent errors which may be generated when seal imprints are inspected with the naked eyes or microscopes.Type: GrantFiled: November 30, 2010Date of Patent: November 5, 2013Assignee: Republic of Korea (National Forensic Service Director Ministry of Public Administration and Security)Inventors: Joong Lee, Young Su Lee, Jun Suk Kim, Ki Woong Moon, Byung Wook Park

Patent number: 6320148Abstract: A method of separating particulate materials of different properties has been developed. It consists of feeding a mixture of dry, powdered materials to one end of the surface of a planar electrode, which is vibrating to move the particles forward. At least one type of the particulate materials acquires a charge via conduction or triboelectrification. Those particles that acquire charges of the same sign as that of the planar electrode are lifted and collected at the V-shaped counter electrodes installed above. The new separation method is particularly useful for removing unburned carbons from fly ash and any other conducting materials from nonconducting ones.Type: GrantFiled: August 5, 1999Date of Patent: November 20, 2001Inventors: Roe-Hoan Yoon, Oh-Hyung Han, Eric S.
