A stent locating device that includes leading wires, a pushing rod for holding the leading wires, and a sheath for loading the pushing rod. The wafer inspection system and a method thereof can determine the kinds of the defect in the wafer during a fabricating procedure, so that it is possible to instantly and correctly determine whether the die on the wafer is a defective. Based on the code of the IC, the SAM selects plaintext data to be encrypted from among the plurality of different pieces of plaintext data. Generally, this involves receiving the monophonic audio data streams from the remote site, and processing them to generate an audio signal for each loudspeaker. A multi faceted graphic user interface may be provided for interaction with a user to speech enable interaction with applications and processes that do not necessarily have native support for speech input. The planar lightwave circuit includes a Y-branch waveguide that branches a DQPSK-modulated optical signal into two optical signals and first and second MZIs that delay the branched optical signals by one bit.
