Abstract: A biometric authentication system includes: an acquisition unit that obtains a feature quantity of a living body; a generation unit that divides the feature quantity and generates a plurality of divided feature quantities; and a collation unit that performs a collation process of the living body by using the plurality of divided feature quantities. According to such a biometric authentication, it is possible to improve the accuracy of the collation process.

Abstract: A virtualization system includes: a virtualizing means for activating a virtual machine to which identification information identifying the virtual machine is assigned and which is capable of executing a predetermined function; a plurality of virtual machines activated by the virtualizing means; and a correspondence table creating means for creating a function correspondence table in which the identification information assigned to each of the virtual machines is associated with a function to be executed by the virtual machine among functions that can be executed by the virtual machines. The virtual machine specifies an associated function in the function correspondence table on the basis of the identification information assigned to the virtual machine, and executes the specified function.

Abstract: To provide an immersion object detection system capable of detecting an immersion object within a detection target area and specifying a position thereof irrespective of a short distance/long distance. A millimeter wave is irradiated to a detection area from a millimeter-wave RF unit through an antenna unit, and the reflected wave is detected. In the case that an immersion object exists in a short-distance area from a radar unit, the directly reflected waves from the immersion object is analyzed, thereby specifying the position of the immersion object, and in the case that the immersion object exists in a long-distance area from the radar unit, the position of the immersion object is specified in accordance with the position of the reflection member which cannot detect among the group of reflection members placed within the detection area.

Abstract: When a sending station intends to transmit data to a target station to which the sending station cannot establish a direct link, the sending station searches for a station, i.e., a relay station which can communicate with the target station by retrieving a communication possible/impossible node list.

Abstract: This switch device for detecting an object comprises a transducer for emitting and receiving ultrasonic signals to and from an object, a transmitter for driving the transducer, a receiver for receiving a signal from the transducer, a gate for detecting a short-distant object, a gate for detecting a long-distant object, and a circuit for setting the timings of the gates in accordance with the detecting ranges of the object.

Abstract: A reproducing stylus for a record having a sound groove, said stylus formed by removing front and back portions of its contact area with the sound groove to obtain an edge line portion having an orientation perpendicular to the direction of record travel and a width d where the effective radius of curvature of the stylus tip is approximately 1/2 d. The edge line portion is formed by reciprocally moving and grinding the tip on a grinding groove.
