  • Patent number: 11429317
    Abstract: Techniques involve storing data. In particular, such techniques involve: obtaining first data to be stored; determining whether the first data is able to be compressed in a compression ratio exceeding a predetermined threshold; and storing, based on the determined result, the first data into a storage device. Accordingly, such techniques can execute corresponding processing for data in a predicted compression ratio, so as to store the data into a storage device. In this manner, such techniques can significantly cut down the overheads for processing data while minimizing a storage space required for storing data.

  • Patent number: 11425372
    Abstract: This application provides a video picture decoding and encoding method and a video picture decoding and encoding apparatus. When it is determined that a merge or skip mode is used, if it is determined through decoding that an MMVD indicator is true, a triangle PU indicator may not be coded. The triangle PU indicator is coded only when it is determined through decoding that the MMVD indicator is false. This reduces a quantity of used coding resources, and can reduce bit overheads of a bitstream.

  • Publication number: 20220191644
    Abstract: Methods and devices are provided for allowing a mobile device (e.g., a key fob or a consumer electronic device, such as a mobile phone, watch, or other wearable device) to interact with a vehicle such that a location of the mobile device can be determined by the vehicle, thereby enabling certain functionality of the vehicle. A device may include both RF antenna(s) and magnetic antenna(s) for determining a location of a mobile device relative to the vehicle. Such a hybrid approach can provide various advantages. Existing magnetic coils on a mobile device (e.g., for charging or communication) may be re-used for distance measurements that are supplemented by the RF measurements. Any device antenna may provide measurements to a machine learning model that determines a region in which the mobile device resides, based on training measurements in the regions.
