Title: Innovations of Dominique H Veillard
Introduction
Dominique H Veillard is a notable inventor based in San Diego, CA. She has made significant contributions to the field of technology, particularly in the area of magnetoresistive heads and filter equalizers. With a total of five patents to her name, her work has had a considerable impact on the industry.
Latest Patents
One of her latest patents is a self-biased magnetoresistive reproduce head utilizing an a.c. sense current. This invention allows for the simultaneous a.c. biasing of the magnetoresistive element while reproducing a pre-recorded signal. The output spectrum of the head includes sidebands that contain signal information associated with a suppressed carrier at twice the bias frequency. This innovation effectively demodulates these sidebands using a locally generated carrier, which is coherent with the bias frequency source, thus recovering the information signal in a spectrum that is immune to low-frequency noise.
Another significant patent is the transversal filter equalizer with minimally interactive adjustments. This invention combines symmetrically located pairs of tap signals in a transversal filter equalizer, such as one using a tapped delay line. By utilizing adders and subtracters, the invention provides partial output signals that are separately controlled in amplitude and phase. These signals are then summed with a partial signal derived from the center tap reference signal to reinsert the d.c. component, resulting in an equalized output signal.
