    摘要： A catalytic partial oxidizer (30) provides syngas (hydrogen and carbon monoxide) to an apparatus intermittently using syngas such as valves (34) feeding NOx traps (35), for brief periods of time. During turndown times when syngas is not being used, either the output of the CPO is diverted (33) to the inlet (13) of an engine (12) through the engine gas recycle (EGR) system (43-46), or the amount of fuel (19) and exhaust (23) applied to the CPO is reduced (24, 26; 59, 60) so that the CPO merely stays warm and in a reduced state, thereby being ready to restart immediately. A mini-CPO (62) may provide syngas and heat to the major CPO (30) during the turndown time when syngas is not being used by the NOx traps.

    摘要： Apparatus, and an associated method, for compensating for the effects of fading, or other distortion, in an MIMO communication system. Analysis is made at a receiving station, such as through channel estimation by a channel estimator, of communication conditions on different sub-channels, defined by different communication paths upon which data streams are communicated to the receiving station from different transmit antenna transducers. Power controllers generate power change requests responsive to the channel estimations. The power change requests are returned to a sending station by way of a feedback channel. And, the power levels at which data is transmitted from different transmit antennas is correspondingly changed.

    摘要： Efficient apparatus and method for Zadoff-Chu (“Chu”) sequence generation avoids additional processing and hardware complexity of conventional quadratic generating formula followed by Discrete Fourier Transform (DFT) with a reference signal generator that produces both a Zadoff-Chu sequence and its DFT. In the wireless communication system (e.g., Long Term Evolution (LTE) system), Chu sequences are extensively used, especially in the uplink (UL). Because of the single carrier operating mode, transmitting a Chu sequence in principle involves a succession of generating that sequence, performing a DFT operation and then an IFFT operation. Assuming that the sequence length is N, the initial sequence generation requires 2N multiplications and the DFT requires more than N log 2(N) multiplications. Given the frequent processing of Chu sequences, this would represent a complexity burden. The invention makes it possible to perform the sequence generation and DFT steps without any multiplication operation, except for possibly calculating certain initial parameters.

    摘要： A method for forming buried ion-exchanged waveguides involves a two-step process. In a first step a waveguide is formed at the surface of a substrate using an ion-exchange technique. After formation of the waveguide, a field-assisted annealing is carried out to move the waveguide away from the surface of the substrate so that it is buried in the substrate. Exemplary field-assisted annealing is carried out at a temperature close to the ion-exchange temperature ±10° C. to optimize results.
