  • Patent number: 8780813
    Abstract: A signalling mechanism in an OFDMA-based wireless communication system in which the number of bits used to indicate the 2-D resource allocation in each frame are reduced, and optimised for the particular frame configuration. The numbers of bits within the MAP-IEs in at least the DL_MAP and optionally also the UL_MAP of each frame, used to represent the Symbol offset and No. of Symbols, are scaled to the frame duration and the subcarrier allocation scheme used for the zone to which the DL-MAP_IE is associated. Likewise, a variable number of bits is used for the subchannel offset and number of subchannels, which can be optimised based on the selected FFT size and subcarrier allocation scheme. The bit numbers in use can be TLV encoded and transmitted within a downlink channel descriptor following the DL_MAP and UL_MAP.

  • Patent number: 8782652
    Abstract: When plural virtual servers are distributed to plural physical servers, efficient distribution is performed in terms of the processing capacity of the physical servers and their power consumption. Firstly a second load of each virtual server in future is predicted based on a first load in a prescribed time period up to the present of each of the plural virtual servers. Next, the schedule is determined to distribute the plural virtual servers to the plural physical servers based on the second load of each virtual server so that a total of the second loads of one or a plurality of the virtual servers distributed to a physical server is within a prescribed range of proportion with respect to processing capacity of the physical server. Furthermore, the distribution is instructed (execution of redistribution) in accordance with the schedule.

  • Patent number: 8782301
    Abstract: When a data request signal is inactivated while a DMA controller is executing DMA data transfer in a burst transfer mode, an address at this time is held and a remaining number of transfer times is counted. After the DMA data transfer in the burst transfer mode is finished, the address and the remaining number of transfer times are re-set in the DMA controller and then the DMA data transfer is executed. This makes it possible to re-transfer data remaining at the timing when the data request signal is inactivated, and the DMA data transfer using the burst transfer mode is executed to or from a module requesting the DMA data transfer by using level of the data request signal.

  • Patent number: 8782428
    Abstract: Even if failure, or the like, occurs during the encryption process, the encryption process is surely resumed. A flag changing unit changes an encryption flag of one disk to being encrypted after an encryption request is received and before the encryption of the data stored on the one disk is started. The flag changing unit changes the encryption flag of the one disk to having been encrypted and changes the encryption flag of the other disk to being encrypted before copying the encrypted data from the one disk to the other disk is started. The flag changing unit changes the encryption flag of the other disk to having been encrypted after copying to the other disk is completed.

  • Patent number: 8781980
    Abstract: The matching apparatus 100 stores, with respect to a branching pattern included in event patterns 140a, a reception time of an event that serves as the branching point in a source node that indicates the transition destination of the event, connects the source node to the branch node by a transition with an interval condition, connects the branch nodes to the link node that indicates the linking point at which these branch nodes are linked together, and thereby generates NFAs 140b. Then, the matching apparatus 100 compares event streams 140c with the NFAs 140b to determine whether the event streams 140c includes the event patterns 140a.
