Abstract:
A face data registration apparatus is an apparatus to register dictionary data for walker authentication by use of a face image. The face data registration apparatus causes a posture data collection unit to collect posture variation data from a plurality of face images obtained by photographing a face of a registrant whose posture (face direction) is changed, further causes a walking data collection unit to collect walking data from a face image obtained by photographing a face of the registrant who actually walks along a passage, causes a synthesizing unit to create dictionary data by synthesizing posture variation data and walking data and registers the created dictionary data as dictionary data used to authenticate a person who walks in the passage by face collation into a dictionary data unit.
Abstract:
An inventive method for multi-symbol polarization switching for differential detection optical systems includes modulating a laser source by a DQPSK modulator, driving the DQPSK modulator with a data block configured for generating multi-symbol polarization-switched DQPSK differential-encoded signals, and polarizing the multi-symbol polarization-switched DQPSK signals with a polarizing modulator whose modulation speed is based on how often polarization states vary, wherein the data block provides a bits manipulation to provide the multi-symbol polarization switching thereby enabling differential detection for recovering correct original data by a receiver.
Abstract:
A method for optical chirp-free optical polarization modulation includes dividing a data modulated optical signal into a first optical path and a second optical path, using a Mach-Zehnder intensity modulator in the first optical path for imparting a π phase difference between adjacent symbols of the data modulated optical signal in the first optical path, adjusting a delay and amplitude of symbols of the data modulated optical signal in the second path so that the symbols in the first path and the symbols in the second path are synchronized and have substantially equal power levels, and combining the first and second optical paths so that symbols from the first and second optical paths are in orthogonal polarizations.

Abstract:
In a person retrieval apparatus, a plurality of extraction processing sections each extract personal biometric information from images taken by a plurality of cameras. A quality determination section determines a quality of each piece of biometric information extracted by the extraction processing sections. A reliability level setting section sets a reliability level to each piece of biometric information on the basis of the quality determined by the quality determination section. The biometric information extracted by the extraction processing sections and the reliability level set by the reliability level setting section are stored in a memory. In this state, in the person retrieval apparatus, the face retrieval section performs person retrieval processing on each piece of biometric information stored in the memory in descending order of the reliability level corresponding to each piece of biometric information.
Abstract:
An object of the present invention is to obtain an ingot containing homogeneous ingredients with suppressing ingredient segregation of Y in the melt-production of an Mg alloy containing Y.An ingot is formed in a solidification time of not more than 200 seconds after an Mg alloy containing Y is melted. The above solidification is desirably performed after the melt liquid of the Mg alloy is stirred and left standing. The above Mg alloy, for example, contains Y in an amount of 0.5 to 20% by weight. There is an advantage that an Mg alloy having low ingredient segregation and containing homogeneous ingredients is obtained. Therefore, in the production of alloys whose performance considerably varies depending on the ingredient concentration, such as functional materials, high-quality products can be produced in good yield rates. In order to achieve the above object, specifically, the raw material is melted in a melting furnace and, after melt drop, the melt liquid is sufficiently stirred and left standing. Thereafter, it is cast into a mold designed so that solidification is completed within the above-defined solidification time. Moreover, it is also possible to shorten the solidification time by casting the melt liquid into a sufficiently water-cooled mold.
Abstract:
A reaction control turbine blade is formed by applying a reaction control material to the surface of an Ni-base superalloy before applying aluminum diffusion coating to the Ni-base superalloy. The reaction control material is Co, Cr or Ru, or an alloy of which main component is selected from a group consisting of Co, Cr, Ru. Thereby, it is possible to enhance the oxidation resistance of the Ni-base superalloy, and to control formation of a secondary reaction zone.
