20080266017 | CONTROLLING COUPLING STRENGTH IN ELECTROMAGNETIC BUS COUPLING - A controller sends signals to an electromagnetic coupler associated with a bus. The signals are arranged to set a coupling strength of the coupler. | 10-30-2008 |
20090302965 | SEMICONDUCTOR DEVICE - A semiconductor device includes transmission lines for conveying signals and transition detectors, each of which checks whether a transmission signal on each of the plurality of transmission lines is transited. If the signal is transited, its transition shape is detected. A signal mode determining unit determines signal transmission modes between adjacent transmission lines in response to output signals from the plurality of transition detectors. Delay units are coupled to the respective transmission lines for adjusting transmission delays of the transmission signals depending on corresponding output signal from the signal mode determining units. | 12-10-2009 |
