Abstract
The invention is a non-contact coupling system for use in interconnecting a large number of electronic modules to a main signal trace via non-contact couplers. A driver sends an electronic signal comprising pulses along the main signal trace. The couplers each have a track of conductive material substantially parallel to the main signal trace. The track of each succeeding coupler is longer than that of the preceding coupler. As a pulse travels from the driver alongside the track of the closest coupler, a pulse is induced therein, although part of the original pulse energy is lost. The remaining lower-energy pulse then couples onto the second-closest coupler but because of the longer parallel track, an induced pulse virtually as strong as the pulse imparted to the first coupler is produced. This phenomenon occurs at every coupler along the main signal trace, resulting in induced pulses that have a relatively low amplitude variation.
