  • Patent number: 10594771
    Abstract: A method for distributed file transfers with high performance and reliability includes creating, on a first Trivial File Transfer Protocol (TFTP) server, a global cache, where the global cache is used to store up to a first portion of a data file. The method further includes storing, on the first TFTP server, in the global cache, one or more continuous data blocks that have exceeded a defined first request rate threshold, where the one or more continuous data blocks make up a subset of the data blocks of the first portion of the data file. The method further includes predicting, on the first TFTP server, a next data block in the data file to be stored in the global cache and in response to predicting the next data block, storing, on the first TFTP server, the next data block in the global cache.

  • Publication number: 20200084472
    Abstract: Innovations in the use of base color index map (“BCIM”) mode during encoding and/or decoding simplify implementation by reducing the number of modifications made to support BCIM mode and/or improve coding efficiency of BCIM mode. For example, some of the innovations involve reuse of a syntax structure that is adapted for transform coefficients to instead signal data for elements of an index map in BCIM mode. Other innovations relate to mapping of index values in BCIM mode or prediction of elements of an index map in BCIM mode. Still other innovations relate to handling of exception values in BCIM mode.

  • Publication number: 20200078599
    Abstract: Disclosed is a transcranial magnetic stimulation treatment apparatus applicable to the technical field of medical devices, comprising a TMS coil, a support, a mechanical arm, a controller, and a positioning device. The positioning device detects the position of a human head and the TMS coil and sends positional information to the controller; the controller controls six driving mechanisms of the mechanical arm to rotate to a corresponding angle. Because the mechanical arm has six degrees of freedom, the TMS coil is capable of stimulating each cerebral region of the brain, and the positioning device is capable of detecting an accurate position of the human head, thereby controlling the mechanical arm to accurately position the TMS coil on the human head, and to reduce manual operation.

  • Patent number: 10567754
    Abstract: Innovations in the areas of hash table construction and availability checking reduce computational complexity of hash-based block matching. For example, some of the innovations speed up the process of constructing a hash table or reduce the size of a hash table. This can speed up and reduce memory usage for hash-based block matching within a picture (for block vector estimation) or between different pictures (for motion estimation). Other innovations relate to availability checking during block vector estimation that uses a hash table.

  • Patent number: 10552973
    Abstract: Exemplary embodiments provide an image vision processing method, device and equipment and relate to: determining parallax and depth information of event pixel points in a dual-camera frame image acquired by Dynamic Vision Sensors; determining multiple neighboring event pixel points of each non-event pixel point in the dual-camera frame image; determining, according to location information of each neighboring event pixel point of each non-event pixel point, depth information of the non-event pixel point; and performing processing according to the depth information of each pixel point in the dual-camera frame image. Since non-event pixel points are not required to participate in the matching of pixel points, even if it is difficult to distinguish between the non-event pixel points or the non-event pixel points are occluded, depth information of the non-event pixel points can be accurately determined according to the location information of neighboring event pixel points.

  • Patent number: 10542274
    Abstract: Innovations are provided for encoding and/or decoding video and/or image content using dictionary modes. For example, some innovations predict current pixel values from previous pixel values stored in a 1-D dictionary. Other innovations predict current pixel values from previous pixel values using a pseudo 2-D dictionary mode. Yet other innovations predict current pixel values from previous pixel values in a reference picture using an inter pseudo 2-D dictionary mode. Pixel values can be predicted from previous pixel values (e.g., stored in a dictionary) that are identified by an offset and a length. Yet other innovations encode pixel values using hash matching of pixel values.
