Publication number: 20230244100Abstract: This application provides a display screen, a display screen protective film, and an electronic device. A transmissive layer of the display screen has a first surface away from a display panel, an orthographic projection of each micro structural unit on the first surface and along a thickness direction is located in a pixel region, and a projection area of the micro structural unit is less than or equal to an area of the pixel region. The micro structural unit may be a curved surface. In this embodiment of this application, the pixel region may include a region in which a sub-pixel is located on the display panel, and a spaced region between the sub-pixel and another sub-pixel that is located around the sub-pixel and adjacent to the sub-pixel. In the foregoing display screen, each micro structural unit mainly bends a display light ray of one sub-pixel. This helps reduce a difference in light refraction degrees between different sub-pixels, and further helps optimize a flash point.Type: ApplicationFiled: January 3, 2023Publication date: August 3, 2023Inventors: Ming Zhu, Xunping Zhou, Huan Ni, Yongxiang Wang, Dachun Zhao, Jingfei Zhang, Shibin Ruan

Publication number: 20230176461Abstract: The optical machine module includes a light emitting module and a modulation module. The light emitting module includes a light source configured to emit linearly polarized light. The modulation module includes a modulation component. The modulation component includes a light-combining prism and a liquid crystal on silicon (LCOS) modulator. The light-combining prism includes four rectangular prisms. The light-combining prism has four sides and four intersection planes formed by the four rectangular prisms. The LCOS modulator includes a first LCOS modulator, a second LCOS modulator, and a third LCOS modulator. The first LCOS modulator, the second LCOS modulator, and the third LCOS modulator are respectively disposed on light emitting sides of three different sides. At least two of the four intersection planes are configured to split light. At least two of the four intersection planes are configured to combine light.Type: ApplicationFiled: March 24, 2021Publication date: June 8, 2023Inventors: Lebao Yang, Zhicong Xie, Bo Tian, Jing Zhang, Fei Zhao, Jingfei Zhang, Zhenlin Xie

Patent number: 11442898Abstract: Techniques described herein relate to systems and methods of data storage, and more particularly to providing layering of file system functionality on an object interface. In certain embodiments, file system functionality may be layered on cloud object interfaces to provide cloud-based storage while allowing for functionality expected from a legacy applications. For instance, POSIX interfaces and semantics may be layered on cloud-based storage, while providing access to data in a manner consistent with file-based access with data organization in name hierarchies. Various embodiments also may provide for memory mapping of data so that memory map changes are reflected in persistent storage while ensuring consistency between memory map changes and writes. For example, by transforming a ZFS file system disk-based storage into ZFS cloud-based storage, the ZFS file system gains the elastic nature of cloud storage.Type: GrantFiled: March 18, 2020Date of Patent: September 13, 2022Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: James Kremer, Mark Maybee, Natalie Ross, Pascal Ledru, Victor Latushkin, Ankit Gureja, Kimberly Morneau, Jingfei Zhang, Gavin Gibson

Patent number: 8573275Abstract: A method and apparatus for detecting exposed and partially separated metal cords 17 in a cut end of a metallic cord reinforced strip 17 includes the steps of conveying and cutting the strip 17 and separating the cut ends and passing the conveyed cut strip 17 past a sensor means 40 for detecting any exposed partially separated metal cords or filaments. The preferred sensor means 40 includes a pair of closely spaced electrically conductive rollers 41, 42, a power source connected to one of the other rollers 41 or 42. When an exposed wire 26 touches both rollers 41 and 42 a circuit is closed giving indication of an exposed wire cord condition.Type: GrantFiled: August 4, 2008Date of Patent: November 5, 2013Assignee: The Goodyear Tire & Rubber CompanyInventors: David Ray Lovell, Jingfei Zhang
