Jefferson Athayde Coelho has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6802046
    Abstract: Systems for performing time domain measurements of a device under test (DUT) are provided. One such system includes a normalization system that receives information corresponding to a model of a test system used for providing differential input signals to a DUT, receives information corresponding to first and second differential input signals provided to the DUT, receives information corresponding to first and second reflected waveforms corresponding to the DUT response to the first and second differential input signals, and computes first and second normalized waveforms using at least a first inverse transfer function of the test system, the first and second normalized waveforms including fewer test system error components than the first and second reflected waveforms, respectively. Methods, computer-readable media and other systems also are provided.
