Patents by Inventor Craig P. Lussier

Craig P. Lussier 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: 8108811
    Abstract: An electrical resistance determination method. Input to the method includes a description of at least one electrical network within a substrate. The description includes specification of a plurality of first ports on a first side of the substrate, and a plurality of second ports on a second side of the substrate, for each electrical network. All of the first ports are electrically isolated from one another. All of the second ports are electrically connected to a common voltage. A computer readable program code, which is executed by a processor of a computer system computes for a first electrical network of the at least one electrical network an electrical resistance between each first port and a port of the second ports. The computer code may also display a perspective plot of the computed electrical resistances as a bar oriented about normal to each first port.

  • Patent number: 7000203
    Abstract: Disclosed is an improved method of determining mutual inductance of wires in an electronic design. First, the invention selects a pair of wires. Then, the invention adds concentric ring lines to the design. The invention then adds straight line segments representing each wire between points where each corresponding wire crosses the adjacent ring lines. Each of the straight lines run from a point where a corresponding wire crosses an outer concentric ring line to a point where the corresponding wire crosses an inner concentric ring line. The invention can then very simply calculate the mutual inductance between the straight line segments (not the actual potentially non-linear wires themselves). The mutual inductance of the straight line segments only comprises an approximate mutual inductance of the wires because the actual mutual inductance of the wires may be slightly different if the wires are non-linear.
