Publication number: 20220044471Abstract: A method further includes the following steps. Firstly, a three-dimensional picture under a generated background condition is generated, wherein the three-dimensional picture includes a three-dimensional object image. Then, a two-dimensional picture of the three-dimensional picture is captured, wherein the two-dimensional picture includes a two-dimensional object image of the three-dimensional object image. Then, an object region of the two-dimensional object image is recognized. Then, an exposed ratio of an exposed area of an exposed region of the object region to an object area of the object region is obtained. Then, whether the exposed ratio is greater than a preset ratio is determined. Then the exposed region is defined as the pick-and-place region when the exposed ratio is greater than the preset ratio.Type: ApplicationFiled: June 30, 2021Publication date: February 10, 2022Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Cheng-Han TSAI, Kuo-Feng HUNG

Patent number: 11234993Abstract: The present invention provides an alcohol extract of Ajuga taiwanensis Nakai ex Murata exhibits significant effects on inhibiting the senescence in human WI-38 lung fibroblasts and human dermal fibroblasts. Moreover, the alcohol extract of A. taiwanensis is able to suppress the expression of the cofilin-1, a protein involved in actin dynamics and cell morphology and found to be increased in senescent cells. Suppression effect of cell senescence by this herb extract is more efficient in mild concentration without over-inhibition of cell viability and growth.Type: GrantFiled: May 26, 2020Date of Patent: February 1, 2022Assignee: NATIONAL YANG-MING UNIVERSITYInventors: Yi-Jang Lee, Yun-Lian Lin, Chung-Sheng Huang, Cheng-Han Tsai, Chun-Yuan Chang, Bing-Ze Lin, Yuan-Heng Tu, Wei-Hsiang Hsu, Pin-Ho Lo
