Publication number: 20240122178Abstract: Disclosed are a caffeic acid-based composite material and a preparation method thereof. The method includes: exposing a cyclodextrin metal-organic framework material prepared from ?-cyclodextrin to a solution of caffeic acid in a short-chain alcohol to obtain a mixed material; and incubating the mixed material, wherein during the incubating, the cyclodextrin metal-organic framework material is in dynamic contact with the solution of caffeic acid in a short-chain alcohol. The prepared composite material includes a cyclodextrin metal-organic framework material and caffeic acid loaded on the cyclodextrin metal-organic framework material, wherein the cyclodextrin metal-organic framework material is prepared from ?-cyclodextrin. The caffeic acid is loaded in an amount of 15-18% of a total mass of the caffeic acid-based composite material. The caffeic acid is located in a cavity of the cyclodextrin metal-organic framework material.Type: ApplicationFiled: March 11, 2022Publication date: April 18, 2024Inventors: Tian DING, Mofei SHEN, Jinsong FENG, Donghong LIU, Shiguo CHEN, Enbo XU, Wenjun WANG, Huan CHENG

Patent number: 11545611Abstract: A very small piezoelectric sensor capable of being mass produced includes a core, a piezoelectric layer on a surface of the core; and a conductive layer on a surface of the piezoelectric layer away from the core. The core is flexible and threadlike, the core is a first electrode of the piezoelectric sensor, and the conductive layer is a second electrode of the piezoelectric sensor. An array of such sensors allows the “skin” of a robot for example to simulate the sensitivity of hair-covered human skin. A method for making the piezoelectric sensor and an electronic device using the piezoelectric sensor are also disclosed.Type: GrantFiled: July 5, 2019Date of Patent: January 3, 2023Assignees: Interface Technology (ChengDu) Co., Ltd., INTERFACE OPTOELECTRONICS (SHENZHEN) CO., LTD., GENERAL INTERFACE SOLUTION LIMITEDInventors: Ming-Ta Chiang, Min-Yu Kan, Meng-Zhu Ma, Huan Ding, Yu-Ju Chen

Patent number: 8990011Abstract: A user device is equipped with one or more sensors that collect data relating to a movement of a user having the user device. An estimated area within which a starting location of the user device is located is determined based on one or more signals received from adjacent signal sources. A plurality of candidate locations is identified within the estimated area as the potential starting location of the user device. Map information of surrounding area that covers the estimated area is also obtained. One or more candidate locations are filtered out depending on whether they could have experienced the movement based on the map information. When one or more re-starting conditions have met during the movement, a then starting location of the user device needs to be determined.Type: GrantFiled: February 28, 2013Date of Patent: March 24, 2015Assignee: Microsoft Technology Licensing, LLCInventors: Chunshui Zhao, Fan Li, Jun Zhao, Huan Ding
