Abstract: A driver's license shooting section comprises a structure that can shoot a driver's license's watermarks both from either its obverse or reverse. And a driver's license shooting controller orders the driver's license shooting section to shoot the driver's license's a watermark from its obverse. Using this result, an authenticity judging section judges the driver's license's authenticity. Then, if the driver's license is back-watermarked type, it is recognized as not authentic, when the driver's license shooting controller orders the driver's license shooting section to shoot the driver's license's a watermark from its reverse. Using this result, the authenticity judger judges if the driver's license is authentic or not. In this way, a legal back-watermarked type driver's license is judged authentic. Consequently, a driver's license's authenticity can be judged properly, no matter whether the driver's license is face-watermarked type or back-watermarked type.

Abstract: A layout for placing a circuit having a plurality of transistors in a small-width region. A search section inputs data on a circuit and searches for a set of routes formed so that passage through a transistor occurs only one time and so that the combination of routes covers the entire circuit network. An extraction section extracts a set of routes having the smallest number of routes. A width determination section determines the layout width from source and drain electrodes, the region between the source and drain electrodes, the region between adjacent pairs of the transistors not combined into a common electrode, the number of transistors, and the smallest number of routes. A layout determination section forms a layout in which the source, drain and gate electrodes of the transistor included in the circuit are placed in a small-width region.

Abstract: In a trunk network, each node, when notified from another node of a change in the state of a group to which external connection ports belong, changes the states of the external connection ports to cause external devices to detect the failure of the transmission route. A port state monitor unit classifies external connection ports into groups in advance and stores the correspondence of the external connection ports and the groups. The port state monitor unit then detects changes in the states of external connection ports. When a change of the state of any external connection port is detected in the port state monitor unit, a group state management unit reports state information that includes the states of groups that correspond to the external connection port to other nodes that make up the trunk network.
