  • Patent number: 8295358
    Abstract: A video encoder encodes the video stream frame by frame. An encoding process generally includes receiving a video frame, subdividing the video frame into uniform pixel blocks, comparing a selected pixel block with the corresponding pixel block in a previous decoded video frame to determine which blocks have changed, copying changed pixel blocks into a contiguous memory block, and adding a preamble block, compressing the blocks. This process may be repeated for each frame using a different size pixel block to determine and select a pixel block size that results in the smallest encoded frame.

  • Patent number: 8296420
    Abstract: A DHT-based global namespace (GNS) is constructed for a network system that includes network attached storage (NAS) devices, including at least one DHT-NAS device (a NAS device having DHT Functionalities) and at least one Existing-NAS device (a NAS device lacking DHT Functionalities). In a DHT Overlay Construction Phase, the DHT-NAS devices construct a DHT overlay. In an Initial Phase, the GNS is created above share folders in the Existing-NAS devices, with mapping of the share folders in the Existing-NAS devices to GNS paths distributed to a key lookup table in the DHT-NAS devices. Each mapping in the key lookup table includes a key, a GNS path, NAS type, IP address of the NAS, and the path within the NAS Share. There is no central GNS mapping table. In a Discovery Phase, the DHT-NAS devices discover the Existing-NAS devices to construct the GNS under the share folders. In a Working Phase, the DHT-NAS devices service GNS requests.

  • Patent number: 8284937
    Abstract: The disclosed is a method for synchronization of the running key that is generated from a shared key and that is used for encryption and decryption in communications encrypted with the shared key using a multi-valued signal. In the method for synchronization, the transmitting node transmits a signal that is formed of a multi-valued signal and that has a predetermined fixed pattern before transmitting data encrypted with the shared key. The receiving node generates a bit discrimination threshold signal that allows for bit discrimination and that has a fixed length, shifts bit by bit the phase of the bit discrimination threshold signal while monitoring bit discrimination with respect to a fixed pattern signal that is to be received, and sets the phase of the bit discrimination threshold signal when the phase of the fixed pattern signal matches the phase of the bit discrimination threshold signal.

  • Patent number: 8284635
    Abstract: When a semiconductor laser is arranged outside a slider and a light is to be guided to the slider through a waveguide, the following problems will be solved: the stability of the flying slider is deteriorated due to a stress from the waveguide; and when an actuator is arranged near the flying slider, the motions of the slider are hindered by the waveguide. A waveguide for guiding a light to a light irradiating unit inside a slider, which floats over a medium and has the light irradiating unit for irradiating a light to the medium; and a waveguide for propagating a light from the light source to the waveguide inside the slider, are included. The two waveguides are not in contact with each other, and a relative portion between the two waveguides is movable.
