    摘要： Provided is an apparatus and method for simultaneous optical wavelength conversion and optical clock signal extraction using semiconductor optical amplifiers (SOAs). The apparatus includes: a wavelength converter receiving a pump beam having input information and a probe beam having a different wavelength from the pump beam, and outputting the pump beam with an overshoot shifted to a red wavelength and an undershoot shifted to a blue wavelength due to non-linear characteristics and self-phase modulation of semiconductor optical amplifiers (SOAs) and the probe beam delivered the input information from the pump beam; an optical divider dividing output paths of the probe beam to which the input information has been delivered and the pump beam having the overshoot and the undershoot; a converted-wavelength extractor filtering the probe beam received from the optical divider; and a clock data regenerator obtaining a pseudo return-to-zero (PRZ) signal from the pump beam received from the optical divider and extracting a clock signal from the PRZ signal. The apparatus and method can simultaneously perform wavelength conversion and optical clock signal extraction on an NRZ signal using an optical method, without converting the NRZ signal into an electrical signal.

    摘要： Disclosed is a method, a system, and a recording medium for collecting content usage information. The method includes the steps of transmitting a usage tracking report message from a DCD client of the terminal to the DCD server; and receiving the usage tracking report message in the DCD server. The usage tracking report message includes first information for identifying a corresponding session, second information including a transaction identifier, third information for identifying a corresponding application, and fourth information including content usage information. Advantageously, the DCD server collects content usage information so that users are provided with highly-preferred contents. The fact that the DCD server collects content usage information and transmits no contents unnecessary to users avoids wasting the network bandwidth and improves content delivery efficiency of the terminals, CP, and DCD server.

    摘要： Provided are a digitally controlled circulator and a radio frequency identification (RFID) reader having the circulator. A power splitter is composed of lumped elements and the values of the elements are digitally changed using switching means, in which the transmission loss of a signal is controlled according to whether the reader is in a transmission state or a reception state. Therefore, the loss can be minimized, and the circulator can be miniaturized and priced down by an integrated circuit (IC) semiconductor process and mounted in a mobile terminal such as a cellular phone.
