  • Patent number: 7739672
    Abstract: Power consumption can be suppressed while maintaining an appropriate execution speed. The information processor has an interpreter for interpreting a source program or intermediate language program and a run-time translator for translating the program into a machine language program native to the computer. The information processor comprises a power-saving request monitor for monitoring whether or not there is a power-saving request from an input interface or a predetermined power-saving request in a given memory, and a power-saving translation controller. The power-saving request makes a request for suppression of the power consumed by the processor. The power-saving translation controller makes a decision as to whether the run-time translator executes run-time translation of the program according to whether there is the power-saving request. Based on the result of the decision, the translation controller instructs the run-time translator to execute the run-time translation.

  • Patent number: 7732217
    Abstract: When detecting fluorescence of a bead chip array, reflected light from a bead is detected at the same time, so as to recognize the bead position. The reflected light can be detected in a similar manner for all beads, regardless of the presence or absence of a fluorescent substance. If the positions of all beads are detected, accurate detection can be achieved by quantifying only the fluorescence at the detected positions. The fluorescence wavelength alone is detected by a first detector using a wavelength selection filter. Other wavelengths are detected by a second detector, thereby obtaining the reflected light. Data on the reflected light is processed into an image for obtaining the bead profile, the bead position is recognized by detecting the center position based on the profile, and the fluorescence is quantified based on the bead position.

  • Publication number: 20100070764
    Abstract: Erroneous deletion of data due to a collision of digest information during data de-duplication using digest information is prevented. When backup data is stored on a backup server 1100, digest information of the backup data is generated and stored in a digest information management table 4200. In addition, when a backup data storage request is made to the backup server 1100, a digest information verification control sub-program 1127 generates digest information of data to be backed up, and performs verification against the digest information of the backed up data already stored on the backup server 1100. If, by this verification, it is found that backed up data having the same digest information is already stored, de-duplication is realized by reusing the existing backed up data without newly storing the data to be backed up.
