Patent number: 12353359Abstract: A file sharing method and an electronic device are disclosed. In the method, a first electronic device displays, in response to a first operation, an application associated with a first file in a first device set. The application includes a first application on a second electronic device. The first electronic device sends an identifier of the first file and an identifier of the first application to the second electronic device in response to an operation that a user selects the first application, so that the second electronic device opens the first file by using the first application. According to the method, more types of files are quickly and conveniently shared with another electronic device in a cross-device manner and are opened by using an associated application.Type: GrantFiled: September 14, 2021Date of Patent: July 8, 2025Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventor: Yubing Guo

Patent number: 12044933Abstract: A method for aligning molecular orientations of liquid crystals and/or polymeric materials into spatially variant patterns uses metamasks. When non-polarized or circularly polarized light is transmitted through or reflected by the metamasks, spatially varied polarization direction and intensity patterns of light can be generated. By projecting the optical patterns of the metamasks onto substrates coated with photoalignment materials, spatially variant molecular orientations encoded in the polarization and intensity patterns are induced in the photoalignment materials, and transfer into the liquid crystals. Possible designs for the metamask use nanostructures of metallic materials.Type: GrantFiled: August 8, 2016Date of Patent: July 23, 2024Inventors: Qi-Huo Wei, Yubing Guo, Miao Jiang, Oleg Lavrentovich, Chenhui Peng, Kai Sun

Publication number: 20240220313Abstract: A method includes that, when detecting that a second application obtains first information in the first application, a first application creates a first object, and generates a unique identifier of the first object to send the unique identifier of the first object to the second application. The first application receives a subscription request that is sent by the second application. The first application adds identification information of the second application to a subscription list of the first object. When an operating system of the first device needs to forcibly kill some applications running on the first device to release system resources due to a limitation of the system resources, the operating system of the first device prolongs a time to live of the first application if the subscription list of the first object includes the identification information of the second application.Type: ApplicationFiled: April 11, 2022Publication date: July 4, 2024Inventors: Haoran Li, Yubing Guo, Zhicheng Dai, Min Zeng

Patent number: 10350597Abstract: A transport device comprises: a fluid cell comprising parallel substrates; an anisotropic electrolyte disposed in the fluid cell; and electrodes configured to apply an AC electric field to the anisotropic electrolyte disposed in the fluid cell. A substrate of the fluid cell includes a pattern that induces a director distortion pattern in the anisotropic electrolyte disposed in the fluid cell. The director distortion pattern has a gradient configured to induce electrokinetic flow of the anisotropic electrolyte in the fluid cell in response to the AC electric field applied by the electrodes. Cargo, such as particles, gas bubbles, or fluid, is dispersed in the anisotropic electrolyte and transported in the fluid cell by the induced electrokinetic flow of the anisotropic electrolyte. The induced electrokinetic flow may be linear, curvilinear, circular so as to induce mixing, depending on the predesigned director pattern.Type: GrantFiled: November 22, 2016Date of Patent: July 16, 2019Assignee: Kent State UniversityInventors: Oleg D. Lavrentovich, Qi-Huo Wei, Sergij V. Shiyanovskii, Chenhui Peng, Yubing Guo
