  • Publication number: 20160103478
    Abstract: According to embodiments, a second control unit creates parity from information loaded into a volatile second memory. When shifting from a normal mode to a sleep mode, the second control unit stores the created parity and the information loaded in the second memory into a buffer of a non-volatile first memory, and issues a power supply shutdown request. A power supply circuit shuts down power supply to the second memory and the second control unit in response to the issued power supply shutdown request.

  • Patent number: 9300901
    Abstract: A system for augmenting the appearance of an object including a plurality of projectors. Each projector includes a light source and a lens in optical communication with the light source, where the lens focuses light emitted by the light source on the object. The system also includes a computer in communication with the plurality of projectors, the computer including a memory component and a processing element in communication with the memory component and the plurality of projectors. The processing element determines a plurality of images to create an augmented appearance of the object and provides the plurality of images to the plurality of projectors to project light corresponding to the plurality of images onto the object to create the augmented appearance of the object. After the images are projected onto the object, the augmented appearance of the objected is substantially the same regardless of a viewing angle for the object.

  • Publication number: 20120123787
    Abstract: According to one embodiment, there is provided a audio format converting apparatus including a audio data dividing unit, first to Nth audio format converting units, and a audio data connecting unit. The audio data dividing unit creates first to Nth divided audio streams from an input audio stream, and adds the same frames as a predetermined number of frames from the head of the (i+1)th divided audio stream to the end of an i-th divided audio stream (i=1,2, to N?1). The first to Nth audio format converting units subject the first to Nth divided audio streams to audio format converting processing in parallel, so as to produce first to Nth converted audio streams. The audio data connecting unit discards the predetermined number of frames from the head of each of the second to Nth converted audio streams, and sequentially connects the first to Nth converted audio streams.
