  • Patent number: 10448432
    Abstract: Systems and methods which provide for detection of a signal using resource elements in the frequency domain where the signal for which detection is provided is multiplexed with other signals having subcarrier spacing that is different than the signal for which detection is provided are disclosed. Embodiments may provide for detection of a physical random access channel (PRACH) signal in a cellular radio communication system using resource elements in the frequency domain, wherein the PRACH signal is multiplexed with signals of other channels (e.g., data and/or control channel signals) of the cellular radio communication system. A frequency domain filter, such as implementing inverse discrete Fourier transform (IDFT) with down-sampling using indices for PRACH recovery, may be utilized to extract PRACH samples from frequency domain resource elements provided in a resource grid corresponding to a different subcarrier spacing than that of the PRACH.

  • Patent number: 10445865
    Abstract: A method and apparatus for converting a standard dynamic range (SDR) video to a high dynamic range (HDR) video. The conversion is adaptive and takes both spatial and temporal information of a current frame and previous frames into consideration such that the majority of pixels falls into the most sensitive regions of human eyes in the target dynamic range, while at the same time, the continuity of luminance is maintained in temporal domain to prevent flickering.

  • Publication number: 20190311142
    Abstract: One embodiment provides a file sharing system. During operation, the system identifies a data file to be sent to a second device of a second user and generates a plurality of coded fragments from the data file based on a generator matrix of erasure encoding. An individual coded fragment does not include plaintext data. The system generates a plurality of sub-files, each of which comprises one or more coded fragments, of the data file. The system attaches a first sub-file to an electronic communication destined to the second device, uploads a second sub-file to a cloud provider, and embeds a link, which may expire and is protected based on a verification code, associated with the uploaded second sub-file into the electronic communication. The system sends the electronic communication to the second device and the verification code in a text message to a cell phone of the second user.

  • Patent number: 10433619
    Abstract: A strap adjustment system has a base body having a bottom wall, two side walls and a strap retaining bar extending between the two side walls, the bottom wall having an aperture therethrough with screw threads extending around an inside surface, and a screw disc having a central protrusion and screw threads extending around the central protrusion. The central protrusion fits through the aperture in the base body by rotating the screw disc so that the threads in the screw disc mate with the threads in the aperture, such that a height of the protrusion above the bottom wall of the base body is adjustable by turning the screw disc. In situations where a high degree of friction is required, the protrusion can be positioned at a maximum height through the aperture, and in situations where a low degree of friction is desired, the protrusion can be positioned lower.
