Title: Robert C. Melville and Artificial Parameter Homotopy Methods
Introduction
Robert C. Melville is an inventor associated with AT&T Bell Laboratories. His work includes a patent on methods for finding the direct-current (DC) operating point of an electrical circuit through artificial parameter homotopy.
Latest Patents
Melville is credited with 1 patent: “Artificial Parameter Homotopy Methods for the DC Operating Point Problem.” The invention describes circuit-simulation methods that use a homotopy equation to move from a tractable starting problem toward the circuit equations whose operating point is sought. It employs models of nonlinear circuit elements that are passive and sufficiently smooth to have well-defined first and second derivatives.
The patent describes approaches using a randomizing matrix and vector, or a known circuit operating point as a starting point. The randomizing component is intended to reduce the likelihood of bifurcations during the analysis.
Career Highlights
Melville’s listed company affiliation is AT&T Bell Laboratories. His patent addresses a technical challenge in circuit simulation: reliably determining a circuit’s DC operating point.
Collaborations
His listed coworkers include San-Chin Fang and Ljiljana Trajković.
Conclusion
Robert C. Melville’s patent presents homotopy-based techniques for circuit analysis, using carefully modeled nonlinear elements and randomization to support the search for DC operating points.
