Patents by Inventor Dennis Dams

Dennis Dams 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: 10402430
    Abstract: A system and method includes providing a graph having a plurality of paths from data. Each of the paths is classified into one of a plurality of classes based upon a criterion. Each of the paths are associated with indicia for representing paths of a class on the graph as being visually distinct from paths of another class on the graph.
    Type: Grant

  • Patent number: 7811244
    Abstract: A device for use in the total cavopulmonary connection (TCPC) in order to optimize its hemodynamics. Although the current procedure of choice for single ventricle heart repairs, the TCPC has reduced the post-operative mortality to the level of simpler types of congenital heart disease repairs, Fontan patients are still subjected to serious long-term complications. The TCPC procedure, which restores the vital separation between oxygenated and deoxygenated blood, also leads to an increased workload for the remaining single ventricle, as it is now responsible for pumping the blood through both the systemic and pulmonary circulation. The present device reduces this workload by altering the surgically created design of the TCPC. Improved fluid mechanics and reduced energy dissipation at the connection site translates into less work for the single ventricle and improved transport of deoxygenated blood to the lungs, which may in turn contribute to improved post-operative results and quality of life.

  • Publication number: 20070220346
    Abstract: Methods and apparatus are provided for exploring paths through a graph representation of a program or another entity. According to one aspect of the invention, at least one property of a state machine, such as a graph representing a software program, is evaluated. One or more paths in the state machine are evaluated using a state exploration algorithm, wherein the state exploration algorithm maintains a stack data structure representing a current path being processed from an entry state to a current state and a visited state cache indicating zero or more states that have been evaluated. When a state satisfies at least one property, such as having an error, each of the states in the path are removed from the visited states cache if the path satisfies one or more predefined criteria. The one or more predefined criteria may comprise a feasibility of the path.

  • Publication number: 20070006151
    Abstract: Methods and apparatus are provided for incremental analysis of one or more properties of a program. According to one aspect of the invention, at least one property of a software program is evaluated, given one or more changes to the software program. Nodes in a derivation graph are identified corresponding to changed edges in a control flow graph representation of the software program, wherein the derivation graph describes an earlier evaluation of the software program. In addition, at least one of the identified nodes in the derivation graph is updated and the derivation graph is traversed outward from a location of a change. The revised derivation graph can optionally be further processed to remove false errors.
