  • Interleaver pattern modification
    Patent number: 7230995
    Abstract: The invention provides a method of interleaving a source data stream using an interleaver pattern in a transmitter. A mother interleaver pattern and an interleaver parameter are accessed. The mother interleaver pattern is modified using said interleaver parameter. Then, the modified interleaver pattern is applied in the transmitter for interleaving the source data stream. The interleaver parameter used by the transmitter for modifying said mother interleaver pattern differs from the interleaver parameter used simultaneously by at least one other transmitter that transmits data at the same time on the same channel. The invention further provides a corresponding deinterleaving method. By decorrelating the interleaver processes in the different streams, the inter-stream interference is reduced.

  • Holder for an identification card
    Patent number: 7228651
    Abstract: An identification card holder, on the front side of which a replaceable identification card can be placed. A spring-loaded yo-yo is fastened and positioned on the reverse side of the holder, such that the yo-yo remains partially or completely invisible as the card, along with its holder, is viewed from the front side. As the yo-yo is integrated with the holder, the result will be a small-sized, readily portable, and easy-to-handle assembly, which can be distanced from a bearer to the proximity of a code reader for an electric lock without releasing the suspension.

  • Decoupling capacitors and semiconductor integrated circuit
    Patent number: 7227211
    Abstract: VSS 302 is provided to a gate portion 304 and VDD 301 is provided to a source portion 305 and a drain portion 306 of a MOS transistor which constitutes a decoupling capacitor, and a potential NWVDD 303 different from that provided to the source portion 305 and the drain portion 306 is provided to a substrate portion 307. If NWVDD 303 is set higher than VDD 301, a depletion layer 309 is spread, so that a leakage current can be reduced instead of reducing a capacitance of the decoupling capacitor. In addition, if NWVDD 303 is set lower than VDD 301 so as not to cause latchup, the depletion layer 309 is reduced, so that the capacitance of the decoupling capacitor can be increased. By changing the potential NWVDD 303 provided to the substrate portion 307, a capacitance value and a leakage current value of the decoupling capacitor can be controlled.
