  • Patent number: 8345785
    Abstract: In MIMO transmission between M transmission antennas and N reception antennas, a transmission signal vector is set as a vector having 2M elements comprising in-phase components and quadrature components of M complex signals, a reception signal vector is set as a vector having 2N elements comprising in-phase components and quadrature components of N complex signals, and a transfer matrix is set as a real matrix comprising 2N rows and 2M columns. Then, a transfer matrix containing IQ mismatch is obtained based on a training signal, thereby executing MIMO encoding and decoding. For learning of the transfer matrix, a training signal which has two linearly-independent signal points on a constellation for each of the transmission antennas is used. With such an arrangement, in MIMO transmission, IQ mismatch in a quadrature modulator and a quadrature demodulator can be compensated and a bit error rate can be improved.

  • Patent number: 8347031
    Abstract: In a storage system in which computers are connected via a network, in order to avoid a state where communication quality is degraded due to poor performance of an apparatus constituting the network, for a transfer data amount, an amount of data sent out from a storage apparatus is suppressed. Moreover, the storage apparatus inhibits a read-ahead process, in accordance with the suppression of the sending out of the data. Furthermore, proper load allocation is realized by migrating a logical storage unit provided by the storage, to another network interface or a second storage apparatus, without changing a configuration of the network.

  • Patent number: 8345990
    Abstract: A method is provided that creates a lecture video capsule containing highlights of an original instructional video based on visual quality and content. The method includes segmenting and recognizing activities in the instructional video using a hidden Markov model (HMM). The activities are classified into three categories: talking head, writing hand and slideshow. The talking head frames are classified as non-content frames, while the writing hand and slideshows are classified as content frames. A non-reference based objective quality assessment of the non-content frames may be performed to detect high quality frames. Statistical parameters of an intensity histogram and a horizontal projection profile (HPP) of the content frames may be used to derive an objective quality measure of the content frames that is used to extract high quality content frames. The selected high quality non-content and content frames form a video clip or capsule, which is a temporally compressed representation of the video.

  • Patent number: 8339130
    Abstract: The surface length of a metal subject to be inspected is evaluated by detecting an eddy current without using a combination of a scale and visual or liquid penetrant inspection. An exciting coil and a detecting coil are scanned above the subject in a length direction. An eddy current detector measures an output voltage corresponding to scanning positions based on an output from the detecting coil. Based on an output voltage distribution curve indicating a distribution of output voltages corresponding to the scanning positions, position information is extracted corresponding to values which are within a differential voltage range and lower by 12 dB than a maximum value of the output voltages on the left and right sides of the distribution. A distance between the positions included in the extracted information is calculated to evaluate the length of a slit which is a defect present on the subject surface.

  • Patent number: RE43896
    Abstract: The present invention provides an image and video indexing scheme for content analysis. According to the invention, a database of images or videos is compressed. By examining patterns in the compression scheme of each image or video, the present invention identifies the content of the data. In one embodiment, an unsupervised learning method is employed where each image or video is sub-divided into smaller blocks (8 pixels×8 pixels, for instance) and each of the smaller blocks is examined for its compression pattern. Then, the patterns associated with each of the smaller blocks is recorded for each of the images in the database and content is retrieved from the database by associating certain patterns or groups of patterns with certain content.
