Abstract: A system that reduces crosstalk and return loss within electrical communication connectors includes at least two compensating capacitors connected in series that compensate each offending capacitor. An additional inductive component that is connected between two compensating capacitors so that the adjustable inductance of the inductive component can be varied to modify the capacitive coupling effect achieved by the compensating capacitors as a function of frequency.

There is no direct contact between the shape-neutral structure and the transmission lines, and the shape-neutral structure does not change the shape of PCB traces and reduces both crosstalk and return loss.

Abstract: An apparatus and continuous process for making milled solid in liquid dispersions comprises several steps: 1) Forming a pre-mill mixture of pre-mix, milling media, and previously milled dispersion. 2) Milling the pre-mill mixture to form a milled mixture of milling media and milled dispersion. 3) Separating a portion of the milled dispersion, which is substantially free of milling media, from the milled mixture. 4) Recycling the un-separated mixture by adding additional pre-mix to form the pre-mill mixture to create a continuous milling process.
