  • Apparatus for closing vascular puncture
    Patent number: 8702750
    Abstract: A method and apparatus for closing a vascular wound includes a guidewire and/or other surgical implement extending from the wound. A hemostatic material is advanced over the surgical implement and into contact with an area of the blood vessel surrounding the wound. The surgical implement is removed. Blood soaks the hemostatic material, and blood clotting is facilitated by the hemostatic agent within the material. A sealing layer of adhesive can be applied to the hemostatic material, confining the blood flow to the material. The vascular puncture wound is sealed by natural blood clot formation.

  • Method and Systems for OFDM Using Code Division Multiplexing
    Publication number: 20140064243
    Abstract: In some embodiments of the invention, OFDM symbols are transmitted as a plurality of clusters. A cluster includes a plurality of OFDM sub-carriers in frequency, over a plurality of OFDM symbol durations in time. Each cluster includes data as well as pilot information as a reference signal for channel estimation. In some embodiments, a plurality of clusters collectively occupy the available sub-carrier set in the frequency domain that is used for transmission. In some embodiments of the invention data and/or pilots are spread within each cluster using code division multiplexing (CDM). In some embodiments pilots and data are separated by distributing data on a particular number of the plurality of OFDM symbol durations and pilots on a remainder of the OFDM symbol durations. CDM spreading can be performed in time and/or frequency directions.

  • VASCULAR WOUND CLOSURE DEVICE AND METHOD
    Publication number: 20140058443
    Abstract: A method and apparatus for closing a vascular wound includes an apparatus that can be threaded over a guidewire into place at or adjacent the wound. The apparatus includes a chamber that encloses a hemostatic material therein. When the apparatus is positioned adjacent the wound as desired, the hemostatic material is deployed from the chamber. A blocking member distal of the hemostatic material functions as a barrier to prevent the hemostatic material from entering the wound. Blood contacts the hemostatic material, and blood clotting preferably is facilitated by a hemostatic agent within the material. Thus, the vascular puncture wound is sealed by blood clot formation.

  • Method for video decoding supported by graphics processing unit
    Patent number: 8542745
    Abstract: A method for utilizing a CUDA based GPU to accelerate a complex, sequential task such as video decoding, comprises decoding on a CPU headers and macroblocks of encoded video, performing inverse quantization (on CPU or GPU), transferring the picture data to GPU, where it is stored in a global buffer, and then on the GPU performing inverse waveform transforming of the inverse quantized data, performing motion compensation, buffering the reconstructed picture data in a GPU global buffer, determining if the decoded picture data are used as reference for decoding a further picture, and if so, copying the decoded picture data from the GPU global buffer to a GPU texture buffer. Advantages are that the data communication between CPU and GPU is minimized, the workload of CPU and GPU is balanced and the modules off-loaded to GPU can be efficiently realized since they are data-parallel and compute-intensive.

  • Spatial diffusion in images
    Patent number: 8457434
    Abstract: The invention is related to spatial diffusion in images. Spatial diffusion helps blurring small discontinuities. Edges become sharper by spatial diffusion as well. A method for generating a spatial diffused image from an input image is described wherein the method comprises applying on the input image an inverted Gaussian spatial bilateral filter with a spatial weight which takes the form of an inverted Gaussian. The inverted-Gaussian-spatial bilateral filter, which uses an inverted-Gaussian function as the kernel of spatial filter, can remove small spots in large smooth areas efficiently.
