  • Patent number: 7103059
    Abstract: Modifications to the 2-stage interconnection to allow flexible scalability. Different switching fabrics having a range of different sizes can be constructed out of the same set of I/O switching nodes through this modified 2-statge interconnection, which can further be recursively invoked to construct large switching fabrics with desirable sizes. The recursive construction incorporating the modified 2-stage interconnection can seamlessly be realized through the five hierarchical levels of physical implementation, including inside-chip implementation, PCB implementation, orthogonal packaging, interface-board packaging and fiber-array packaging. The routability of the resulting switching fabric is always guaranteed and self-routing mechanism is also pertained.

  • Patent number: 7102742
    Abstract: A gemstone fluorescence measuring device according to the invention generally includes an ultraviolet (“UV”) emission chamber, a UV radiation source, and a light meter assembly. The UV radiation source includes an upper light emitting diode (“LED”) and a lower LED that radiate a gemstone under test from both above and below the gemstone. The UV radiation source provides both trans-radiation and direct radiation to the gemstone, and the UV radiation source has an adjustable intensity, thus facilitating calibration of the fluorescence measuring device. The light meter assembly includes a light detector that detects the visible light emitted from the gemstone under test in response to the UV radiation. The light detector is configured to simulate the spectral characteristics of the human eye. The fluorescence measuring device converts the measured visible light into a numerical lux reading, which can then be converted into a fluorescence grade for the gemstone under test.

  • Patent number: 7103332
    Abstract: An apparatus and method for compensating for the frequency offset of a received signal in a receiving apparatus of a mobile communication system. In the present invention, a sine component is calculated by adding I and Q channel signals resulting from downconverting a training sequence inserted between data symbols, and a cosine component is calculated by subtracting the Q channel signal from the I channel signal. Using the cosine and sine components at two time points, tangent components for the two time points are computed and thus first and second phase values are obtained. The frequency offset is estimated by determining the slope of a second-order line derived from the first and second phase values. The frequency offset of the received signal is compensated for based on the estimated frequency offset.

  • Patent number: 7102876
    Abstract: An interleaving striped capacitor substrate structure for pressing-type print circuit boards is disclosed. To meet the high-frequency, high-speed, and high-density requirements in modern electronic systems, the interleaving striped capacitor substrate structure uses several dielectric materials of different dielectric coefficients to make a dielectric layer. One dielectric layer can be stacked on another to form a multi-layered capacitor substrate so that a single capacitor substrate can provide the highest capacitance required for the decoupling capacitor to suppress high-frequency noise signals, and the lower dielectric coefficient substrate required for high-speed signal transmission. This simultaneously achieves the effects of reducing high-frequency transmission time and suppressing high-frequency noise.
