Patent number: 11519659Abstract: Disclosed herein is a refrigerator. The refrigerator includes a body, a storage compartment disposed inside the body, an evaporator configured to generate cold air and disposed behind the storage compartment, and a duct configured to supply the cold air generated by the evaporator to the storage compartment. The duct includes a first discharge hole through which air flowing in the duct is discharged, a plurality of second discharge holes through which air is discharged at a speed lower than a speed of the air discharged through the first discharge hole, and a damper configured to selectively regulate a flow of air to guide the air in the duct to the first discharge hole or the plurality of second discharge holes.Type: GrantFiled: August 7, 2020Date of Patent: December 6, 2022Assignee: Samsung Electronics Co., Ltd.Inventors: Joohee Song, Byungkwan Yang, Hyejeong Oh, Jooyong Lee, Byungwoo Jeon, Hyoju Han

Publication number: 20200094359Abstract: Provided are methods and systems for aligning multiple parts using simultaneous scanning of features of different parts and using feature-based coordinate systems for determining relative positions of these. Specifically, a feature-based coordinate system may be constructed using one or more critical dimensions between features of different parts. The scanner may he specifically positioned to capture each of these critical dimensions precisely. The feature-based coordinate system is used to compare the critical dimensions to specified ranges. The position of at least one part may be adjusted based on results of this comparison using, for example, a robotic manipulator. The process may be repeated until all critical dimensions are within their specified ranges. In some embodiments, multiple sets of features from different parts are used such that each set uses its own feature-based coordinate system. The part adjustment may be performed based on the collective output from these multiple sets.Type: ApplicationFiled: November 26, 2019Publication date: March 26, 2020Applicant: The Boeing CompanyInventors: Byungwoo Lee, Michael Yee-Chih Wang
