Patent application number | Description | Published |
20090113269 | DATA DESCRAMBLING APPARATUS AND DATA DESCRAMBLING METHOD - When performing data descrambling for data including errors, a countermeasure against an error in a seed value that is required for the descrambling is realized in a system having no CPU. | 04-30-2009 |
20100027398 | OPTICAL DISC DEVICE AND RECORDING DEVIATION AMOUNT TRANSFER METHOD - There is provided an optical disc device which can evaluate in a short time as to whether an optical disc is recorded with satisfying the standard or not. | 02-04-2010 |
20100070720 | MEMORY ACCESS METHOD - The memory access method of the present invention comprises preparing upper addresses separately from the address width of the Pseudo SRAM ( | 03-18-2010 |
20100235719 | ENCODER AND OPTICAL DISK RECORDING APPARATUS - An encoder includes an information holding section which stores flag bytes and an initial address, a data generation section which generates sets of first parity symbols from the initial address and the flag bytes, a parity generation section which generates and outputs sets of second parity symbols, for each column of data units included in the block, from the columns of data units included in the block and input user control data. The data generation section generates the addresses and the sets of first parity symbols, required to generate the columns of data units included in the block, based on the initial address and the flag bytes, selects necessary portions from the flag bytes and the addresses and the sets of first parity symbols generated, and outputs the portions to the parity generation section, as the columns of data units included in the block. | 09-16-2010 |
20100287336 | EXTERNAL I/O SIGNAL AND DRAM REFRESH SIGNAL SYNCHRONIZATION METHOD AND ITS CIRCUIT - In an LSI that determines timing of DRAM refresh by a refresh timer to synchronize an external I/O signal and DRAM refresh timing with each other, a circuit configuration capable of controlling a value of the refresh timer by a CPU at arbitrary timing is employed. Alternatively, a circuit configuration capable of controlling the value of the refresh timer at arbitrary timing by an external terminal, or a circuit configuration capable of controlling the refresh timing directly from the external terminal without through the refresh timer. | 11-11-2010 |
20130232556 | SETTING METHOD, DEVICE AUTHENTICATION METHOD, DEVICE AUTHENTICATION SYSTEM, AND CONTROLLER - A method of setting which includes: obtaining, from a smart meter, an ID of the smart meter; obtaining, from a HEMS-controller, an ID and a certificate of the HEMS-controller and an ID and a certificate of an appliance controlled by the HEMS-controller; generating management information in which the ID of the smart meter, the ID and the certificate of the HEMS-controller, and the ID and the certificate of the appliance are associated with one another; and transmitting, based on the management information, the ID and the certificate of the HEMS-controller and the ID and the certificate of the appliance which are associated with the ID of the smart meter, to the smart meter. | 09-05-2013 |
20150262316 | POWER RATE CALCULATION METHOD AND POWER RATE CALCULATION DEVICE - A power rate calculation method for used in a facility that has the plurality of privately-used areas and a common area, one or more power generators are installed in the common area, includes: obtaining a plurality of first power amounts consumed by each of the privately-used areas, detecting whether or not a second power amount generated by the one or more power generators is larger than or equal to a third power amount consumed by both of the plurality of privately-used areas and the common area; and calculating the power rates from the plurality of first power amounts by applying a first rate structure when the second power amount is larger than or equal to the third power amount and by applying a second rate structure that is different from the first rate structure when the second power amount is smaller than the third power amount. | 09-17-2015 |
20150263546 | STORAGE BATTERY CONTROL METHOD AND STORAGE BATTERY CONTROL APPARATUS - A storage battery control method includes receiving capacity information indicating chargeable and dischargeable capacities of a plurality of storage batteries; receiving use permission information indicating whether at least some of the plurality of storage batteries are available for the frequency control; determining target storage batteries to be used for the frequency control among storage batteries of the plurality of storage batteries indicated as available by the received use permission information; determining a bid capacity used for the frequency control, the bid capacity being equal to or less than a total value of the chargeable and dischargeable capacities of the target storage batteries; and submitting a bid for the frequency control under a bid condition including the bid capacity. | 09-17-2015 |
