Abstract: A fuel cell system is provided with a first separation layer and a buffer solution layer disposed between a liquid-phase fuel storage layer and an anode of a membrane electrode assembly. A vapor-phase fuel is transferred to the buffer solution layer through the first separation layer, condensed, and diluted to produce a liquid-phase fuel with a low concentration in the buffer solution layer, and the low concentration liquid-phase fuel is supplied to the membrane electrode assembly. A second separation layer may be interposed between the first separation layer and the fuel storage layer. Fuel is supplied by a passive supplying method so that the system can be small with a high efficiency and unnecessary power consumption can be prevented. The fuel cell system can be operated regardless of orientation.

Abstract: In a communication system using an Orthogonal Frequency Division Multiple Access (OFDMA) scheme, at least one value mapped to the number of threshold subchannels is compared with the number of subchannels allocated to a signal transmission apparatus in an associated Orthogonal Frequency Division Multiplexing (OFDM) symbol when transmission data including m bits is input. In response to a comparison result, (m−k) bits are generated from the transmission data using at least one of clipping and rounding. The (m−k) bits are converted to an analog signal and the analog signal is transmitted. The number of threshold subchannels is preset to determine whether to use clipping, rounding or both.

Abstract: A synchronization extraction apparatus for a communication system and a method thereof are disclosed. A frame synchronization is obtained in a manner that the sum of an input signal and a delay signal is obtained without obtaining a simple correlation value between the input signal and the delay signal, and then a correlation value between a summed signal and the delay signal is obtained. The synchronization extraction apparatus and method can reduce the implementation complexity and power consumption in obtaining the frame synchronization, and thus increase the battery cycle of a terminal provided with the synchronization extraction apparatus or method.
