  • Patent number: 10775512
    Abstract: An electronic device, a method, and a chipset for receiving global navigation satellite system (GNSS) signals are provided. The electronic device includes a processor configured to: downconvert, by an input/output (I/O) mixer including a first multiplier and a second multiplier, a modulated radio frequency wave to an intermediate frequency, where the modulated radio frequency wave is input to first inputs of the first multiplier and the second multiplier, and where an in-phase signal and a quadrature phase signal based on a square wave are input to second inputs of the first multiplier and the second multiplier, respectively; filter the downconverted modulated radio frequency wave; and convert the filtered downconverted modulated radio frequency wave to a digital signal.

  • Patent number: 10685474
    Abstract: The present invention provides a method for repairing incomplete 3D depth image using 2D image information. The method includes the following steps: obtaining 2D image information and 3D depth image information; dividing 2D image information into 2D reconstruction blocks and 2D reconstruction boundaries, and corresponding to 3D reconstruction of blocks and 3D reconstruction boundaries; analyzing each 3D reconstruction block, partitioning into residual-surface blocks and repaired blocks; and proceeding at least one 3D image reconstruction, which extends with the initial depth value of the 3D depth image of each of the residual-surface block and covers all the corresponding repaired block to form a repair block and to achieve the purpose of repairing incomplete 3D depth images using 2D image information.

  • Patent number: 10652690
    Abstract: Method and apparatus to analyze and present location information in an easy-to-digest manner are disclosed. In one embodiment, each piece of location information can include a piece of location-designating information and a piece of location-related information. Location-designating information is primarily for identifying location. Location-related information is information related to location-designating information. The location-designating information and the location-related information can be supplied by a mobile device. With the help of location-related information, each piece of location-designating information can be more accurately transformed into a label to help identify a location. The amount of location information can be reduced. All of the location-designating information pertaining to a given area can be consolidated into one piece of location-designating information related to the label.
