Abstract: In a case in which a freeze operation is performed, an evaluation period is set for an image sequence in a cine memory based on first reference information. An image group belonging to the evaluation period is individually evaluated, and thus a recommended image is selected from the image group. The recommended image is displayed after the freeze operation.

Abstract: A computer-implemented method, in accordance with one embodiment, includes receiving a request to migrate data from a source virtual tape system to a destination virtual tape system. A serial number of a logical volume having the data in the destination virtual tape system is added to the destination virtual tape system. An interim logical volume is created on the destination virtual tape system. A conversion table associating the serial number of the logical volume is updated with a serial number of the interim logical volume. The data in the logical volume is migrated to the interim logical volume. In response to completing the data migration, data access requests are satisfied using the logical volume.

Abstract: An optical transmission system that includes a first optical device including a first optical signal adjustment unit that adjust light intensity of an input light signal for each wavelength, and a first control unit that controls the first optical signal adjustment unit, and a second optical device including a second control unit. The second control unit sends, to the first control unit, transmitted light information being information relating to a transmitted light signal, and the first control unit controls the first optical signal adjustment unit in such a way that the transmitted light signal is allowed to pass by using the transmitted light information.

Abstract: In an optical submarine cable system, the amount of work involved in setting up a terminal station device increases in association with an increase in volume. Thus, a wavelength multiplexing device according to the present invention comprises: a wavelength multiplexing means for causing input light inputted from a plurality of input ports for receiving optical signals to pass within a passband determined by a set center frequency and a set bandwidth, and outputting the light from an output port; an optical monitoring means for measuring optical power of the optical signals for each optical frequency and generating optical waveform information; a calculation means for calculating a main signal center frequency which is the center frequency of the optical signals and a main signal bandwidth which is the bandwidth of the optical signals; and a control means for setting the set center frequency to the main signal center frequency and setting the set bandwidth to the main signal bandwidth.

Abstract: Since safe utilization of an optical transmission system is impaired if a system is adopted in which a wavelength band is divided into sub-bands and a different user is allocated to each sub-band, the optical signal monitoring device of the present invention includes: an optical signal information generating means for monitoring wavelength multiplexed signal light comprising sub-band optical signals belonging to each of a plurality of sub-bands classified by means of identification information, and generating wavelength multiplexed signal information including optical power information of each wavelength in the wavelength multiplexed signal light; a sub-band signal information generating means for generating sub-band signal information associated with the identification information, for each of the plurality of sub-bands, on the basis of the wavelength multiplexed signal information; and a sub-band signal information control means for controlling the utilization of the sub-band signal information, on the basi

Abstract: A system disconnection detection circuit for a distributed location power source having a generating element and an invertor for converting a generated output from the generating element into an AC output superimposes a selected signal on the AC output of the invertor. The circuit detects system disconnection on the output side of the invertor on the basis of the AC output of the invertor on which the selected signal has been superimposed.

Abstract: This invention relates to a process for manufacturing a shaped active carbon by using a one step phenol-formaldehyde resin, a modified phenol-formaldehyde resin or a mixture thereof as a binder. By this method, a shaped active carbon can be obtained having increased mechanical strength without deterioration of the adsorption capacity.
