  • Publication number: 20230137479
    Abstract: This application provides a method for reducing interference between a radar and an uplink frequency band. A first network device obtains a characteristic of a radar signal on the uplink frequency band, and determines a corresponding protection measure based on the characteristic of the radar signal, to reduce interference between the radar signal and the uplink frequency band. In this way, when 5G communication collides with the radar in time domain and frequency domain of the uplink frequency band, the 5G communication and the radar can still coexist. This improves utilization of a wireless spectrum.

  • Patent number: 11295113
    Abstract: A system includes an identification system and an information database for linking an unidentified animal (UA) to a registered animal. A requester sends the media corresponding to the UA to the identification system. The UA images are used for determining an orientation and position of the UA. A selected 3DSM of the registered animal may be reconfigured using a 3DSM generator by moving the movable joints of the 3DSM to have the same orientation and position as the UA images. A 2DSM generator is used to generate 2D synthetic images (2DSIs) of the selected 3DSM. The images of the unidentified animal are compared to the 2DSIs of the selected 3DSM. When a match probability exceeds a threshold probability, a match is reported to a requester. The requester can obtain permission from an owner to get access to the information pertaining to the UA.
