  • Publication number: 20170235677
    Abstract: A computer system that is composed of a host computer, a storage device and a management computer. The storage device comprises a port for connecting with the host computer, a cache memory, a processor, and a plurality of logic volumes which are logical memory regions. For each logic volume, the port, the cache memory and the processor are divided into logic partitions, as resources that are used for reading and writing in the logic volume. The host computer reads and writes with respect to the logic volumes. If a failure occurs in the storage device, the management computer issues a command to the storage device to allocate the resources of a logic partition for which reading/writing performance is not ensured to a logic partition for which reading/writing performance is ensured.

  • Patent number: 9485438
    Abstract: An image detection unit extracts image feature values from images of each camera. An image conversion unit computes a blend rate according to the image feature values and composites an image of a superposition area wherein a plurality of camera images overlap. An assessment is made of a correspondence of the image feature values of each image in the superposition area, and a determination is made that a solid object is present if the correlation is weak. Furthermore, a determination is made that the solid object is present in the superposition area if the image feature values in each image have locationally overlapping portions. In such a circumstance, the image is composited with the blend rate of the image with a greater image feature value set large.

  • Patent number: 8611840
    Abstract: In a mobile communication terminal, a communication control section controls communication on the basis of a selected radio communication system or frequency band and manages the state of communication. A signal-strength-indicator acquiring and storing section acquires signal-strength indicators and stores it. A communication-state acquiring section acquires the state of communication. A signal-strength-indication displaying control section determines whether a radio communication system or a frequency band is being searched for from the communication state. When it is being searched for, antenna bars indicative of signal strength are not shown or flashed when the signal-strength indicator is indicated on a display section.

  • Patent number: 8346300
    Abstract: A communication terminal optimally switches between the use of multicast reception and unicast reception, in consideration of the mobile radio environment of each terminal. For example, received signal strength indicator information is acquired at a received signal strength indicator information acquisition time calculated using a content reception time. Either multicast reception or unicast reception is selected according to the acquired received signal strength indicator information and content reception is performed. An optimal reception system can be selected and reception failure can be reduced. In addition, by performing a dynamic switching of reception methods as such, the base station-end can perform multicast delivery rather than unicast delivery when possible to communication terminals in favorable mobile radio environments, thereby significantly reducing the traffic load placed on communication paths.
