Publication number: 20240124002Abstract: A method for changing a route when an error occurs in an autonomous driving AI includes collecting error information of the AI when an error of the AI has occurred, extracting, from a storage, past error information about a same kind of AI as that of the AI based on the error information of the AI, generating an error analysis result based on the past error information, generating an error analysis result message based on the error analysis result, and determining whether the driving of the autonomous driving vehicle needs to be stopped based on the error analysis result message.Type: ApplicationFiled: August 24, 2023Publication date: April 18, 2024Applicant: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Jeong-Woo LEE, Kyoung-Wook MIN, Kyung Bok SUNG, Dong-Jin LEE, Jeong Dan CHOI

Patent number: 10214827Abstract: Methods of preparing metal and metal alloys with partially microcrystalline anodic coatings are disclosed. Associated article therefrom are correspondingly disclosed. The partially microcrystalline anodic coatings exhibit fade and pattern removal resistance when subjected to sterilization processes. Partially microcrystalline anodic coating can be prepared by impregnation of micropores of a metal or metal substrate with metal precursor species, conversion of the metal precursor species into metal hydroxides, and one or more additional treatments to promote phase transformation of the metal hydroxide product into metal oxides solids and bonding with metastable metal oxide substance in the pore structure of the metal or metal alloy substrate.Type: GrantFiled: February 11, 2016Date of Patent: February 26, 2019Assignee: SANFORD PROCESS CORPORATIONInventors: Timothy P. Cabot, John J. Tetrault, Dong-Jin Sung

Patent number: 9702053Abstract: Embodiments may generally take the form of systems and techniques for reducing or eliminating crazing in anodized metal. In particular, one embodiment may take the form of a method for sealing an anodized metal member including placing the anodized metal member in a sealing bath having water. The sealing bath initially has a first temperature that is less than a sealing temperature. The method also includes continuously heating the sealing bath to the sealing temperature, maintaining the bath at the sealing temperature for a period of time, and removing the anodized metal member from the sealing bath after the period of time has lapsed.Type: GrantFiled: June 29, 2012Date of Patent: July 11, 2017Assignee: Apple Inc.Inventors: Max A. Maloney, Dong-Jin Sung

Patent number: 9260792Abstract: Methods of preparing metal and metal alloys with partially microcrystalline anodic coatings are disclosed. Associated article therefrom are correspondingly disclosed. The partially microcrystalline anodic coatings exhibit steam, superheated steam, alkaline and acidic resistance. Partially microcrystalline anodic coating can be prepared by impregnation of micropores of a metal or metal substrate with metal precursor species, conversion of the metal precursor species into metal hydroxides, thermal treatment to dry out moisture and to promote phase transformation of the metal hydroxide product into metal oxides solids and bonding with metastable metal oxide substance in the pore structure of the metal or metal alloy substrate, and hydrothermal sealing to create sealed partially microcrystalline anodic coating.Type: GrantFiled: December 12, 2013Date of Patent: February 16, 2016Assignee: SANFORD PROCESS CORPORATIONInventors: Timothy P.
