System and method for improving a digital PLL's performance by making fine grained adjustments to the loop gain. A preferred embodiment comprises a plurality of loop gain adjustors (such as loop gain adjustors 605, 606, 607, and 608) that can incrementally adjust the loop gain.

Overlay modulation of COFDM using phase and amplitude offset carriers
Systems and methods are presented for transmitting additional data over preexisting differential COFDM signals by modulating existing data carriers with a phase and an amplitude offset. In exemplary embodiments of the present invention, additional data capacity can be achieved for an COFDM signal which is completely backwards compatible with existing satellite broadcast communications systems. In exemplary embodiments of the present invention additional information can be overlayed on an existing signal as a combination of amplitude and phase offset from the original QPSK symbols, applied for each information bit of the overlay data. With two additional levels of modulation, a receiver can demodulate the information from each of the previous stages and combine the information into a suitable format for soft decoding. The first stage of demodulation will be recovery of overlay data from the amplitude modulated D8PSK. Because other amplitude variations due to multi-path are also expected, the data gathered from the FFT in the receiver must be equalized to the channel conditions. After channel equalization has been performed, soft overlay data can then be derived from the distance off the unit circle. In order to recover the phase modulated overlay data, the equalized symbols must first be differentially demodulated and corrected for any common phase error offset. After common phase removal, overlay phase information can be obtained. |

A measuring method and a device are adapted for the positioning of a wheel for mash seam resistance welding in the butt-joining of steel strips on continuous processing lines. A rotary roller which is fastened to a movable frame is positioned in a measuring position that is vertically below a reference wheel.

Wavelength dependent reflective sample substrates for Raman and fluorescence spectroscopy
A material which is generally transparent in the visible region of the spectrum but reflective at laser wavelengths reduces undesirable, substrate-induced Raman and fluorescence scattering. A substrate provides a surface for supporting the sample, with the material being disposed between the surface of the substrate and the sample. The material is substantially transparent in the visible region of the spectrum but reflective at the laser wavelength, thereby minimizing unwanted Raman or fluorescence scattering that would be produced by the substrate if the material were not present. The substrate will typically be a glass microscope slide or multi-cell well plate. The optical filter material is preferably a multilayer dielectric filter acting as a “hot mirror” that reflects near-infrared energy. An advantage of visible transmission is that it allows back illumination from behind/underneath the slide or well plate, thereby being visible to a microscope's eyepiece or video camera. Methods and article are also disclosed. |

Image processing apparatus, image processing method, program, and storage medium for correcting chromatic aberration
There is a problem in that when magnification chromatic aberration correction is carried out, the difference in reproducibility of high-frequency components, depending on the spatial position, between a color for which position shift correction is not performed and a color for which position shift correction is performed may influence the image quality of an output image. In order to perform magnification chromatic aberration correction, high-frequency components, which are lost due to the position shift correction of a color for which position shift correction is carried out, are extracted from a color for which position shift correction is not carried out, and are added to the color for which position shift correction is carried out. Therefore, the high-frequency components are restored in a pseudo manner. |

In a light emitting device, luminance irregularities caused by fluctuation in threshold of TFTs for supplying a current to EL elements among pixels hinder the light emitting device from improving the image quality.

Even when threshold is fluctuated among pixels, each threshold is held in the capacitor means 111 of each pixel, and therefore, influence of the threshold fluctuation can be removed. Since the threshold is stored in the capacitor means 111 alone and the voltage between two electrodes is not changed while a video signal is written, fluctuation in capacitance value has no influence. |

Circuits and methods for controlling quiescent current in amplifiers
A power amplifier provides relatively stable quiescent current while maintaining relatively high signal gains and peak to quiescent current ratios. The power amplifier has an input stage and a current mirror stage and incorporates a control transistor between these stages. The control transistor transitions to the triode mode for small inputs and offset voltages thereby reducing the amplifier circuit's gain. However, the control transistor transitions from the triode region to saturation as the input signal becomes larger thereby allowing the amplifier circuit to maintain a relatively high gain for large inputs. Accordingly, better quiescent current characteristics can be obtained without significantly sacrificing performance. |

Isolating interface with a differentiating circuit comprising a capacitive barrier and method for transmitting a signal by means of such isolating interface
A known method for parallel two-way symmetrical signal transmission by means of an isolating interface with a differentiating circuit comprising a capacitive barrier is improved. When restarting communication in the selected direction after a longer break, a pilot signal is conducted via the transmitting plates for the communication in the reverse direction and capacitive compensators to one of the receiving plates for communication in the selected direction. Threshold levels for comparisons of the signals of the first and second time derivative are decreased, the capacitance of capacitive compensators is then set to reduce output the output signal and finally communication is reestablished. Transmitting plates for communication in the reverse direction are now connected to the receiving plates for communication in the selected direction through the capacitive compensators with the capacitance adjusted as described above. This provides satisfactory signal transmission even when a thick layer of an electrically well conductive liquid appears between the plates of the isolating interface. |
