  • Patent number: 8112498
    Abstract: To provide an easy and simple mapping between objects representing different network systems A and B. In the configuration where data of an object, a system component, is available in another system, it is provided with an intermediate model 102 which is mutually accessible. The intermediate model has an intermediate object 103corresponding to a component. Each system performs mapping to the intermediate object 103 an item of a corresponding component 106 of the system, and transmits data to an mapped item. In addition, the system accesses the intermediate object to obtain data corresponding to the item when component data of the other system is needed.

  • Publication number: 20110293190
    Abstract: Image data defining a reference image and each input image in a sequence of images is processed to detect changes in the images. A value is calculated for each pixel defining the spatial rate of change of homogeneity of the image data at that pixel. Different regions of pixels in each image are selected and the values within each region are concatenated to define a vector for each region. The vectors are then processed to compare corresponding regions in each image. The results of the comparison define a correlation map identifying areas in the images in which change has occurred.

  • Patent number: 8054884
    Abstract: Each of an image coding apparatus and an image decoding apparatus uses a motion compensated prediction using virtual samples so as to detect a motion vector for each of regions of each frame of an input signal. Accuracy of virtual samples is locally determined while the accuracy of virtual samples is associated with the size of each region which is a motion vector detection unit in which a motion vector is detected. Virtual samples having half-pixel accuracy are used for motion vector detection unit regions having a smaller size 8×8 MC, such as blocks of 8×4 size, blocks of 4×8 size, and blocks of 4×4 size, and virtual samples having ¼-pixel accuracy are used for motion vector detection unit regions that are equal to or larger than 8×8 MC in size.

  • Patent number: 8046127
    Abstract: A vehicle-mounted electronic control apparatus can perform a variety of abnormality detections while reducing the control load of a microprocessor in the abnormality detection of a volatile backup memory that is backed up by an on-board battery. The apparatus includes a control CPU which is fed with power from a main power supply circuit upon closure of a power switch, a nonvolatile control memory and a backup memory. Even if the power switch is opened, the backup memory, being a partial area of a RAM memory, is fed with power through an auxiliary power supply circuit connected directly to the battery. When the battery is replaced with a new one and connected again, a power supply interruption monitoring memory is reset. At the start of operation of the control CPU, the backup memory is initialized based on reset information, and the power supply interruption monitoring memory is rewritten into a set state.

  • Patent number: 8046796
    Abstract: A table creating unit receives program information and an upper limit bit rate of EPG data, creates a table of EIT [current/next] on the basis of the information and upper limit bit rate, and determines the frequency of transmission of the table in consideration of the upper limit bit rate and the lower limit of the frequency of transmission of the table. A stream transmitting unit receives the table and the frequency of transmission, converts the table to stream information, and transmits a stream at a frequency determined based on the transmission frequency. Therefore, data transmission is carried out satisfying both the limit of the upper limit bit rate and the limit on the transmission frequency.
