  • Publication number: 20250039887
    Abstract: New radio download numerology allocation information may be obtained through master information block data, system information block data, radio resource control signals, or signals or a physical downlink numerology indication channel, and used along with a reference signal detected in a search space to obtain resource element positions in an antenna port reference signal in a resource block that belongs to a particular band slice according to a reference signal allocation scheme for a band slice numerology. A physical download control may then be decoded based upon one or more resource elements of the reference signal, allowing the connection of, e.g., an enhanced mobile broadband, massive machine type communication, or ultra-reliable/low-latency application to a communications network thereby. Alternatively, multiple physical downlink control channels may be blindly demodulated at each of a number calculated reference signal locations, and one channel selected based on passing a cyclic redundancy check.

  • Patent number: 12211267
    Abstract: The present disclosure provides a method, apparatus, medium and device for extracting a river drying-up region and frequency, and belongs to the technical field of remote sensing. The method for extracting a river drying-up region and frequency can be applied to efficiently acquiring river drying-up information for a long time within the large spatial region. With the inverse normalized difference water index (iNDWI) and the maximum value composite (MVC) method for the remote sensing images, the present disclosure omits the troublesome step of separately extracting a river range for each image in the conventional method. In addition, the present disclosure quickly obtains the drying-up frequency by counting the total number of available images and the number of non-water images at the same pixel position, and yields a greater efficiency for extracting the river drying-up region and frequency.

  • Patent number: 12207387
    Abstract: Employing undulator devices as x-ray radiation sources requires expensive and bulky support systems for operation, which are not robust and lead to limited ranges of generated radiation energies. A force-compensated undulator device is described. The device includes an undulator having first and second magnet arrays disposed along a central axis. The first magnet array is translatable along the central axis. The device further includes a compensator unit disposed adjacent to the first magnet array with the compensator unit having a first row of magnets disposed along a compensator axis with the compensator axis being parallel to the central axis, and a second row of magnets disposed along the compensator axis. The first row of magnets is translatable along the compensator axis. The compensator provides magnetic forces that neutralize the system dynamic magnetic forces generated by the undulator.

  • Publication number: 20240406380
    Abstract: A block of a video frame can be encoded using inter-prediction, and the motion vector of the block can be encoded based on a motion vector reference of a merge candidate. Some video codecs allow a large range of temporal and spatial neighbors to be considered as potential merge candidates. It is not practical to perform motion compensation and rate-distortion optimization for all possible merge candidates. To address this concern, a hardware-efficient process can be implemented to rank and select merge candidates. A reference frame priority list is applied to select a subset of potential reference frame combinations. An efficient top-K sorting algorithm is applied to identify merge candidates for each reference frame combination and keep top merge candidates with highest weights. Motion compensation and rate-distortion optimization are performed on the top merge candidates only.
