Abstract: A computer implemented method, system, and/or computer program product reduce noise in a circuit. A level of noise imposed by an aggressor line on a victim line is determined. The aggressor line and the victim line are an aggressor/victim line pair from multiple aggressor/victim line pairs in a circuit. Determination of the noise level is conducted during a predetermined window of time during which a signal is being transmitted along the aggressor line. Each of the multiple aggressor/victim line pairs are ranked according to a level of noise being imposed by each aggressor line on each victim line. The spacing between a highest ranked aggressor/victim line pair is then expanded.

Abstract: The present invention provides a power saving method and apparatus for powering a lower voltage device from a higher voltage power source. The apparatus includes a switch having an input coupled to an output of the higher voltage power source. The apparatus further includes a high-to-low voltage converter having an input coupled to an output of the switch. The apparatus also includes a power plug having an input coupled to an output of the high-to-low voltage power converter, and an output configured to receive a power socket of the low voltage device. Finally, the apparatus includes a switch actuator coupled to the power plug and the switch. When the power plug is operatively engaged within the power socket of the lower voltage device, the switch actuator closes the switch. When the power plug is operatively disengaged from the power plug, the switch actuator opens the switch.
