| 20090251088 | MOTOR DRIVING CIRCUIT - A motor driving circuit includes at least one set of switching elements, each set of switching elements being two switching elements connected in series to each other, and a diode connected in parallel with one of the two switching elements connected on a power source side, a terminal of a motor to be driven being connected to a junction point between the two switching elements. A voltage transfer element is provided for transferring, from the junction point between the two switching elements, a voltage of a counter electromotive force generated at the motor, to an input end of the other of the two switching elements connected on a ground side. | 10-08-2009 |
| 20100329391 | INFORMATION DETECTING APPARATUS AND METHOD - Proposed are a highly reliable information detecting apparatus and an information detecting method. This information detecting apparatus includes a high pass filter unit configured in a manner of being able to freely change a time constant and for extracting a high frequency content of the communication signal, a squelch detection unit for detecting a region in which a signal level of the high frequency component of the communication signal exceeds a predetermined squelch detection threshold, an information detection unit for detecting the information superposed on the communication signal based on a detection output of the squelch detection unit, a DC fluctuation detection unit for detecting a level fluctuation of a DC component of the communication signal, a control unit for controlling the high pass filter to lower the time constant of the high pass filter unit when the level fluctuation of the DC component of the communication signal is detected by the DC fluctuation detection unit, and a mask unit for masking the detection output of the squelch detection unit so as to make it appear that the squelch detection unit has not detected a region exceeding the squelch detection threshold while the control unit is lowering the time constant of the high pass filter unit. | 12-30-2010 |
| 20100332695 | INFORMATION DETECTING APPARATUS AND METHOD - Proposed is a highly reliable information detecting apparatus and method. In an information detecting apparatus and method for detecting transmission information a transmission signal in which a burst period of transmitting a burst signal and a space period as a no-signal period are repeated in a pattern according to the subject matter of the transmission information, whether the absolute value of a signal amplitude level of the transmission signal is not less than a first threshold is detected, whether the absolute value of a signal amplitude level of the transmission signal is not less than a second threshold is detected, and whether the amplitude level displacement of the transmission signal is based on noise or the reception of the transmission information is determined based on the detection results. | 12-30-2010 |

| 20090030953 | METHOD AND A SYSTEM FOR DATA MIGRATION - A data migration method is provided which can provide a user at a low cost with a function of migrating data from an existing storage when an additional storage is installed. A business application is operated by using a business server and a first storage. When the capacity and performance of data used by a business application become insufficient, a second storage is installed to compensate for insufficiency. In this case, the management server collectively copies data and configuration information of the first storage to the second storage, the data and configuration information are deleted at a later time in accordance with migration command information selected from a GUI screen. It is therefore possible to migrate necessary data and configuration information of the first storage to the second storage, without making a user be conscious of the details of the configuration information of logical devices of a storage. | 01-29-2009 |
| 20100049934 | STORAGE MANAGEMENT APPARATUS, A STORAGE MANAGEMENT METHOD AND A STORAGE MANAGEMENT PROGRAM - A purpose is to perform migration considering an I/O load that will be generated during the migration. To migrate data from one array group to another array group, a bandwidth that is available for use between the movement source array group and the movement destination array group is calculated, a volume whose write I/O amount is smaller than the calculated bandwidth is selected wherein the write I/O amount is the information transmission amount of information that is written, and data is migrated from the selected volume to the movement destination array group. | 02-25-2010 |
| 20110320599 | MANAGEMENT SYSTEM AND COMPUTER SYSTEM MANAGEMENT METHOD - A management apparatus for managing a computer system stores configuration information of multiple management-target apparatuses based on multiple first information received from multiple management-target apparatuses. The management apparatus, based on the configuration information and multiple additional component application condition information, determines whether or not to use multiple additional component information to acquire multiple second information from the multiple management-target apparatuses. The management apparatus, in a case where a determination to carry out acquisition is made, uses the multiple additional component information to receive the multiple second information from the multiple management-target apparatuses, and based on the multiple second information, either creates or updates the management information of the multiple management-target apparatuses. | 12-29-2011 |
| 20120030346 | METHOD FOR INFERRING EXTENT OF IMPACT OF CONFIGURATION CHANGE EVENT ON SYSTEM FAILURE - A management system, which manages multiple monitoring target apparatuses, computes a certainty factor denoting the probability that a certain configuration change is the root cause of a performance failure that has occurred in a certain monitoring target apparatus based on rule information, computer system performance information, and a configuration change history, and displays management information from the standpoint of the configuration change based on the computation result. | 02-02-2012 |
