Patent number: 11977175Abstract: Provided is a technology for increasing accuracy of position estimation by estimating a position of a signal source based on an error due to altitudes of a sensor and a signal source and an error due to a pitch of an aircraft as well as an error due to curvature of the earth. At this time, a position estimation method may include receiving measurement data from a plurality of sensors, estimating first position data of the signal source based on the measurement data, identifying an altitude error of the first position data, and estimating second position data that is data obtained by correcting the first position data based on the altitude error.Type: GrantFiled: September 21, 2021Date of Patent: May 7, 2024Assignee: AGENCY FOR DEFENSE DEVELOPMENTInventors: Sang Won Kim, Dong Keun Lee, Jeung Min Joo, Jung Hoon Kim, Sung Jin Jo

Patent number: 11472840Abstract: The present disclosure relates to an acetylcholine receptor-binding peptide and, more particularly, to novel peptides which exhibit a wrinkle amelioration effect by binding the peptides to an acetylcholine receptor on which acetylcholine acts, thereby blocking secretion of acetylcholine. Peptides according to the present disclosure suppress secretion of acetylcholine by having a high binding strength with the acetylcholine receptor, thereby strongly binding the peptides to acetylcholine. Therefore, a cosmetic composition and a pharmaceutical composition comprising the peptides according to the present disclosure as an active ingredient exhibit an excellent wrinkle ameliorating effect.Type: GrantFiled: June 25, 2018Date of Patent: October 18, 2022Assignee: SKINMED CO., LTD.Inventors: Sung Hyun Kim, Won Il Choi, Yong Chul Shin, Jeung Hoon Lee, Young Sung Yun, Jin Hwa Kim

Publication number: 20220054425Abstract: The present invention relates to nanocapsules coated with chitosan, and a use thereof. A method for preparing nanocapsules having a particle size of 500 nm or less having excellent stability, and a poorly soluble drug is loaded in the nanocapsules prepared by the method, so that an excellent skin permeability rate of drug-containing nanocapsules, drug delivery into the skin achieved thereby, and efficacy caused by the drug are exhibited. Increase in the bioavailability of active ingredients in vivo through oral administration of the prepared nanocapsules is confirmed, and thus it is expected that nanocapsules coated with chitosan of the present invention are used to develop an excellent delivery system, of which the delivery efficiency of a poorly soluble drug or the active ingredients to animals, and companion animals is significantly increased, in the pharmaceutical field, cosmetics industry, food industry, and the like.Type: ApplicationFiled: December 20, 2019Publication date: February 24, 2022Applicant: SKINMED CO., LTD.Inventors: Won Il CHOI, Sung Hyun KIM, Yong Chul SHIN, Jeung Hoon LEE, Jin Hwa KIM, Young Sung YUN
