Abstract: The light energy necessary for the precure process is held by the RFID at the holographic memory. The controller acquires the light energy corresponding to the temperature of the recording position detected by the temperature sensor out of the precure information acquired by the RFID reader. The exposure time (light emitting time of LED) Te in the precure process is calculated based on the calculating equation Te (sec)=En (joule)/Pd (watt) from the energy En and the intensity Pd of light irradiated onto the recording position detected by the light detector.

Abstract: An improved nanophosphor scintillator liquid comprises nanophosphor particles in a liquid matrix. The nanophosphor particles are optionally surface modified with an organic ligand. The surface modified nanophosphor particle is essentially surface charge neutral, thereby preventing agglomeration of the nanophosphor particles during dispersion in a liquid scintillator matrix. The improved nanophosphor scintillator liquid may be used in any conventional liquid scintillator application, including in a radiation detector.

Abstract: A method backs up computer data by organizing update requests into groups. All update requests in one group complete concurrently before requests of a subsequent group complete.

Abstract: To provide an optical recording apparatus capable of effectively suppressing useless fixation to an information-unrecorded area during a fixing process with a simple structure, and an optical head. Upon recording information, a movable lens of an expander lens 104 is positioned in an information recording position. In an information fixing process, the movable lens of the expander lens 104 is positioned in a fixing-process position. In this case, a range of irradiation to the recording medium with the data light becomes somewhat wider than that in the information recording process. Accordingly, it is possible to fix the information to an area irradiated with the data light in the information recording process without fail. In addition, the irradiation range is only somewhat wider than that in the information fixing process, making it possible to minimize the region uselessly subjected to the fixing process.

Abstract: A hologram apparatus comprises a vibration detection beam generation unit to apply a vibration detection beam, incoherent to the data and reference beams and to detect the presence/absence of vibrations, to the hologram recording medium; a light reception/determination unit to receive the vibration detection beam emitted from the medium after the beam is applied to and propagates through the medium and to determine whether the beam receiving position is within a preset range; and an interruption unit to interrupt at least one of the data and reference beams from being applied to the medium, when this unit has determined that the position of beam reception is not within the preset range.

Abstract: Systems and methods for processing content packages such as human-readable documents identify and analyze content type. Structural and logical evaluation of a Content package is performed, followed by analysis and indexing of concepts within the package. Analysis and identification of concepts and sub-concepts may be an iterative process. Concepts are indexed in accordance with different rule sets representing Different consumer needs and perspectives. Customers can then use the indices to navigate large groups of content packages based on the concepts contained within those packages and also on keywords associated with concepts.

Abstract: The present invention provides a method and system for the reference, archival and retrieval of symbolically linked information despite idiosyncratic symbol usage. A master symbol database stores a plurality of master symbols, wherein each master symbol is formatted according to a predetermined structure. Each master symbol in the master symbol database is linked to a parent identifier that identifies a unique object. Users may archive or retrieve symbolically linked information in an information database by providing an input symbol. The input symbol is normalized and the master symbol database is searched to find a matching master symbol. The parent identifier linked to the matching master symbol is then used to retrieve or archive information in the information database.

Abstract: A portable cargo container and cover system includes a container portion for stowing cargo in a vehicle cargo area, a cover portion for concealing cargo from view in the cargo area, and an attachment means for removably attaching the system to the cargo area. When the system is removed from the vehicle cargo area, cargo stowed in the container portion can be manually transported in the container portion outside the vehicle.

Abstract: A hologram apparatus comprises a light detection unit detecting a light intensity of at least one of the data beam and the reference beam; a determination unit determining whether light intensities of the data beam and the reference beam reach to a reference value which can form a hologram having certain diffraction efficiency, based on the light intensity detected by the light detection unit; and a block unit blocking application of at least one of the data beam and the reference beam into the hologram recording medium, based on the result of the determination of the determination unit indicating that the light intensities of the data beam and the reference beam reach to the reference value.
