  • Publication number: 20160291899
    Abstract: A storage control device includes a processor. The processor is configured to receive a designation of a target volume among a plurality of volumes including a plurality of data pieces distributively arranged in a plurality of storage apparatuses. The target volume is to be migrated from a first storage apparatus among the plurality of storage apparatuses to a second storage apparatus different from the plurality of storage apparatuses. The processor is configured to determine a layout of first data pieces of the target volume on basis of a number of data pieces arrangeable in the first storage apparatus and a first number indicating a number of data pieces of the target volume. The processor is configured to perform a control operation, on basis of the determined layout, such that the first data pieces are arranged in the first storage apparatus and collectively migrated to the second storage apparatus.

  • Patent number: 7867141
    Abstract: A physical activity measuring system analyzes analyzing body motions of a user to accurately determine the exercise intensity. The system includes a portable device which is adapted to be carried by the user and is equipped with a body sensor and an indicator for indication of the exercise intensity. The body sensor senses the user's body motions to give corresponding motion strength. The portable device has a processor which constitutes an exercise calculator which has a predetermined relationship between a default standard deviation of the motion strength and an exercise intensity scale. The exercise intensity calculator collects a time series data of the motion strengths within a predetermined first time frame, obtains a standard deviation of thus collected motion strengths, and converting the standard deviation into an instant exercise intensity within the intensity scale in accordance with the predetermined relationship.

  • Patent number: 7183562
    Abstract: Charged-particle-beam (CPB) mapping projection-optical systems and adjustment methods for such systems are disclosed that can be performed quickly and accurately. In a typical system, an irradiation beam is emitted from a source, passes through an irradiation-optical system, and enters a Wien filter (“E×B”). Upon passing through the E×B, the irradiation beam passes through an objective-optical system and is incident on an object surface. Such impingement generates an observation beam that returns through the objective-optical system and the E×B in a different direction to a detector via an imaging-optical system. An adjustment-beam source emits an adjustment beam used for adjusting and aligning the position of, e.g., the object surface and/or the Wien's condition of the E×B. The adjustment beam can be off-axis relative to the objective-optical system. For such adjusting and aligning, fiducial marks (situated, e.g.

  • Patent number: 6493675
    Abstract: A system for managing a work flow functions efficiently at a high speed. To attain this, the system includes a plurality of work flow support units, and a work flow support unit management unit. The work flow support unit management unit determines which work flow support unit is to manage a work flow. At this time, the work flow support unit management unit refers to the load condition of each work flow support unit to instruct the work flow support unit indicating the smallest load state to manage work flows, thereby preventing the process load from concentrating on a specific work flow support unit.

  • Patent number: 6285113
    Abstract: A surface acoustic wave actuator is disclosed which includes unidirectional interdigital transducers disposed on both sides of a vibrator and an electrical combiner. One of the unidirectional interdigital transducers and external power supply are connected to an input port, and the other unidirectional interdigital transducer is connected to an output port of the electrical combiner. The electrical combiner combines input energy from an external power supply and surface acoustic wave energy is electrically converted by one of the unidirectional interdigital transducers, and input to the other unidirectional interdigital transducer. Surface acoustic waves excited by the other unidirectional interdigital transducer propagates on a vibrator, and is input to the other unidirectional interdigital transducer again after passing one unidirectional interdigital transducer and the electrical combiner.
