Abstract
Method for determining at least one optimal trajectory between a point and a target situated in a medium and forming a centered volume, the position of each of whose points is known with geometrical uncertainties, characterized in that it consists in defining for the centered volume a gain which takes different values from the center to the peripheral boundary, and a zero value outside the centered volume; in determining a statistically significant number of instances of the positions of the centered volume as a function of the geometrical uncertainties which affect it, and in determining an aggregate gain at each point; in defining a volume of interest, site of the points with positive aggregate gains in the medium; in defining curvilinear trajectories between at least one entry point and at least one exit point of the said volume of interest; in integrating the aggregate gain along each of the said curvilinear trajectories in such a way as to obtain a profit associated with each trajectory, and in retaining all the trajectories whose profit is greater than a threshold.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
