  • Patent number: 8223766
    Abstract: An objective of the present invention is to secure the continuity of the communication between a client device and a standby server device, when a failure occurs and switch to the standby device is performed. A communication processing unit of the client device establishes connection with a plurality of server devices simultaneously by transmitting a UDP packet to the plurality of server devices by multicast. After establishing the connection, data of the application is transmitted by multicast to the plurality of the server devices. In the even of a failure, a standby server device receives the data packet multicast from the client device to continue the inter-application communication.

  • Patent number: 8218648
    Abstract: This invention enables to generate encoded data without noticeable image quality degradation when reproducing an image at a lower resolution not to mention the original resolution. To accomplish this, when setting is done to transmit an image captured by a digital camera to a network, code stream forming information CF is set to “2” to arrange the encoded data of each tile in a resolution order. To suppress image quality degradation when reproducing at an intermediate resolution, stream conversion information SC is set to “2”. When encoding image data in compression processing, block overlap processing of suppressing discontinuity of data at the boundary between adjacent blocks is executed as many times as the count set in the stream conversion information. The obtained encoded data is arranged in accordance with the code stream forming information CF and output.

  • Patent number: 8185683
    Abstract: Transparency of resources is provided and ordering in an access is guaranteed between nodes on a computer network. In an information processing system in which a plurality of processor units are connected to each other by a switch, a global address space is introduced into which effective addresses of the processor units are mapped and which is shared by the plurality of processor units. In response to an access request packet issued by a processor unit and designating an effective address of a target node, a bridge for routing an input and output bus of a processor unit to an input and output bus of the switch converts the effective address of the target node into a global address by appending to the packet a node identification number identifying the target node, and outputs the access request packet designating the global address to the switch. After an access request packet for a write operation is output, the bridge confirms whether the write operation is completed in a target node.

  • Publication number: 20120111550
    Abstract: An ebullient cooling device having a simple structure and capable of limiting the bubbles to an appropriate volume. The ebullient cooling device for cooling a heat generating element is provided with a plurality of vertically arranged cooling channels comprising a lower channel (2), a middle channel (3) and un upper channel (4). Each cooling channel has cooling fins (12) for guiding a refrigerant to flow in a vertical direction, and a vapor discharge path (16) formed at the side of the cooling fins (12) that is opposite the side in contact with the heat generating element. Furthermore, flow path partition/vapor discharge guiding plates (18) are provided between the cooling channels so that the bubbles that have been generated are guided to the vapor discharge path (16) and prevented from moving into the subsequent cooling channel.

  • Patent number: 8127564
    Abstract: A cooling system has a configuration in which a cooling system for an inverter device and a motor generator also serves as a cooling system for a battery. In this configuration, a control device performs temperature-raising control of the battery when a battery temperature is below a prescribed temperature lower limit value. The control device controls an operation of a switching valve such that cooling water from a cooling medium path is outputted to a bypass path. Further, if a cooling water temperature is lower than a prescribed temperature, the control device controls the inverter device such that a power loss during a switching operation in a switching element included in the inverter device becomes larger than a power loss during normal control. As a result, the cooling system having a small-sized, low-cost configuration rapidly recovers capacity decline of the battery, which occurs at low temperatures.

The router 24 routes the access to upstream channels each assigned a memory bandwidth available for access to the memory, the upstream channels being virtual channels supported by the processor unit. In this process, the router refers to a table storing identifiers of the downstream channels and identifiers of the upstream channels in association with each other so as to allocate to the peripheral device the upstream channel corresponding to the downstream channel used by the peripheral device, in response to the access from the peripheral device.

  • Patent number: 8094726
    Abstract: This invention enables to generate encoded data without noticeable image quality degradation when reproducing an image at a lower resolution not to mention the original resolution. An image a digital camera can capture takes three sizes L, M, and S. When the size L is designated, stream conversion information SC is set to “2”. When the size M is designated, the stream conversion information SC is set to “1”. When the size S is designated, the stream conversion information SC is set to “0”. When encoding image data in compression processing, block overlap processing of suppressing discontinuity of data at the boundary between adjacent blocks is executed as many times as the count set in the stream conversion information.

  • Patent number: 8049449
    Abstract: In a brushless motor for an electric power steering device having a configuration of 2 poles and 3 slots, or of an integral multiple thereof, a stator coil is supplied with current containing a higher harmonic component. A difference of 0.5% to 1.5% is provided between the higher harmonic component content rate of the stator coil current and the higher harmonic component content rate of the induced electromotive force generated in the stator coil with rotation of a permanent magnet, thereby mitigating the influence by an armature reaction generated in the induced electromotive force to reduce torque ripples. The difference between the higher harmonic component content rates is set on the basis of a change that occurs in the induced electromotive force due to the armature reaction at a time of supplying electricity to the armature coil.

  • Patent number: 8032849
    Abstract: Disclosed is a procedure or design approach for functional modules that may be used in connection with a multiprocessor integrated circuit chip. The approach includes keeping the dimensions of each module substantially the same and having the bus, power, clock and I/O connection configured the same on all modules. Further requirements for ease of use are to generalize the capability of each module as much as possible and to decentralize functions such as testing to be primarily performed within each module. The use of such considerations or rules substantially eases the design of a given type of custom chips, and based upon an initial chip design greatly facilitates the design of further custom chips, similar in application, but subsequent to the successful completion of the initial chip.

  • Patent number: 8006000
    Abstract: There is provided a technique of accessing a memory of a processor from a peripheral device, thereby the security is ensured while efficiency is being pursued. An address converter 14 includes an address conversion table for converting an effective address into a physical address. The address conversion table stores the effective address to which an area in a memory of a processor unit 10 is allocated to each peripheral device 30 and identification information of an access source to which access permission is given, in association with each other. When the peripheral device 30 accesses, the address converter 14 determines to permit access to the effective address under the condition that the device identification information, included in an access request packet, by which the peripheral device 30 can be uniquely identified, matches the identification information of the access source corresponding to the effective address, in the address conversion table, designated by the access request packet.
