  • Apparatus and method for channel sounding based on aggregated physical protocol data unit
    Patent number: 11979866
    Abstract: The present disclosure provides a wireless communication method. The wireless communication method includes a first apparatus communicating with at least one second apparatus in a wireless local area network (WLAN) system. The wireless communication method generates an aggregated physical layer protocol data unit (PPDU) including a first null data packet (NDP) based on a first protocol standard and a second NDP based on a second protocol standard and transmits the aggregated PPDU to the at least one second apparatus, wherein the first NDP and the second NDP have a same duration in different frequency bands.

  • BOOK SCANNING USING MACHINE-TRAINED MODEL
    Publication number: 20220207668
    Abstract: This application discloses a technology for flattening a photographed page of a book and straightening texts therein. The technology uses one or more mathematical models to represent a curved shape of the photographed page with certain parameters. The technology also uses one or more photographic image processing techniques to dewarp the photographed page using the parameters of the curved shape. The technology uses one or more additional parameters that represent certain features of the photographed page to dewarp the photographed page.
