Publication number: 20240134185Abstract: Provided is a laser scanner. The laser scanner includes a laser transmitter configured to output a laser radiated towards an object, a laser receiver configured to receive a laser reflected from the object, and an oscillating mirror of which a mirror surface is coated with a thin metal film to reflect the received laser reflected from the object and be penetrated by an electromagnetic wave incident from an outside the laser scanner. The received laser reflected from the object is reflected by the mirror surface of the oscillating mirror coated with the thin metal film and received by a laser receiver, and the electromagnetic wave incident from the outside the laser scanner penetrates the mirror surface of the oscillating mirror and then dissipates.Type: ApplicationFiled: January 6, 2023Publication date: April 25, 2024Applicant: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Jung Hwan HWANG, Jong Hwa KWON, Chang Hee HYOUNG

Polymer resin formulation having anti-microbial or anti-coagulability and preparation method thereof
Patent number: 7491768Abstract: The present invention relates to an anti-microbial or anti-coagulating polymer resin and a method for preparing the same, and a medical appliance or instrument using the same, and more particularly to a method for preparing an anti-microbial or anti-coagulating medical polymer resin comprising the steps of simply mixing a polymer resin with at least one kind of pharmaceutically active material without using a solvent. The pharmaceutically active material is preferably an anti-microbial or anti-coagulant. According to the present invention, an anti-microbial or anti-coagulating material that is safe to a human body is mixed with a polymer resin by simple addition in an environmentally favorable non-solvent method, thereby maintaining superior anti-microbial effects even after high temperature molding, minimizing a released amount of anti-microbial to increase anti-microbial effect durability, and solving a toxic problem in a body.Type: GrantFiled: June 25, 2003Date of Patent: February 17, 2009Inventors: Woong-Sig Moon, Jae-Chul Kim, Youn-Seop Byoun, Kyoo-Hyun Chung, Heun-Soo Kang, Ki-Oh Kong, Jung-Hwa Hwang -
