Patent number: 10977133Abstract: Improved methods, systems and apparatus for storing and repairing multimedia files are provided that overcome the limitations of existing multimedia file repair technologies. Backup copies of the multimedia container information associated with given multimedia content data are stored, along with the multimedia content data, on an external storage detachably coupled to a recording device. A primary copy of the multimedia container information is stored on an internal storage associated with the recording device. The recording of the primary container information and the content data is performed in real-time or nearly real-time as the content data is captured by the recording device. In the case of an abnormal event (e.g., battery failure, disconnect of storage media), container information may be selected from the primary copy or the backup copies of the container information, thereby increasing the likelihood that the container file can be successfully repaired or regenerated.Type: GrantFiled: May 19, 2017Date of Patent: April 13, 2021Assignee: SZ DJI TECHNOLOGY CO., LTD.Inventors: Gao Ping Bai, Tai Wen Liang, Yuan Hua Zheng, Mingyu Wang

Patent number: 10759757Abstract: A method of preparing a crystalline contrast agent for magnetic resonance imaging from a zwitterionic carboxylic pyridyl ligand includes mixing metal ion and the pyridyl ligand and obtaining crystals therefrom. The crystalline contrast agent includes a manganese-organic or gadolinium-organic 3D framework. The crystalline contrast agent is employed in a kit and a pharmaceutically acceptable composition. The method allows for preparing crystalline contrast agents with superior properties with easily available starting materials and with an economic and efficient process. The method allows for preparing crystalline contrast agents with exceptional water-stability and water-solubility, which exhibit high longitudinal relaxivities and with excellent stabilities under physiological conditions and low cytotoxicity. Further provided is a method for in vivo imaging of a subject, in particular a human, comprising administering the crystalline contrast agent to the subject.Type: GrantFiled: September 21, 2016Date of Patent: September 1, 2020Assignees: Macau University of Science and Technology, Southern Medical UniversityInventors: Jinxiang Chen, Jianxin Pang, Shuwen Liu, Li-Ping Bai, Zhi-Hong Jiang
