    Abstract: Calculations are performed, based on a switching criterion, to select at least one of a direct communication link or an indirect communication link to transmit data between a movable object and a remote terminal. The data is transmitted using the at least one of the direct communication link or the indirect communication link selected based on the calculations. During at least a portion of a duration for the transmission of the data using the at least one of the direct communication link or the indirect communication link, backup data is transmitted using a backup communication link to ensure connectivity between the movable object and the remote terminal in event of interruption in the selected at least one of the direct communication link or the indirect communication link occurs. The backup data including at least a portion of the data transmitted between the movable object and the remote terminal.

    Abstract: 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.

    Abstract: Mappings of keys to actions can automate various vehicle systems. Some automations can provide lane departure warnings or emergency light reminders. Mapping keys can be matched based on vehicle condition data gathered from vehicle sensors. When a mapping key matches vehicle condition data, the vehicle action automation system can cause the vehicle to perform the one or more actions from that mapping. Mapping keys can be rules-based and/or model-based. Keys for lane departure mappings can specify vibration patterns expected when a vehicle drives over lane delineators. These vibration-based mappings can include keys with vibration patterns, e.g., defining vibration frequencies or vibration locations. Keys for emergency light mappings can be based on conditions such as (1) the vehicle being on the road, stopped, not in traffic, and not at a stop signal; (2) components of the vehicle having failed; or (3) weather conditions.

    Abstract: An image processing method includes capturing an initial image of a subject based on a preset initial exposure value, capturing a compensatory image of the subject based on a preset compensatory exposure value greater than the initial exposure value, calculating a synthesized pixel value at a pixel coordinate position based on a pixel value of an initial pixel at the pixel coordinate position in the initial image and a pixel value of a compensatory pixel at the pixel coordinate position in the compensatory image, and generating a captured image based upon the synthesized pixel value.

    Abstract: Imaging systems having multiple optical modules are provided to achieve higher zoom ratio and better displaying effect. The FOVs or focal length ranges of the multiple optical modules may be designed to achieve a zoom ratio higher than either of the multiple optical modules and a Picture-in-Picture function. The gravity center of the imaging system may not be significantly varied during the zooming in and zooming out of the multiple optical modules.
