Latest Patents

Leahu's latest patents include innovative systems and methods for the localization of objects buried in the seabed. These systems utilize a sub-bottom profiler to scan targeted areas based on predetermined parameters. A localization engine models the data using a Levenberg-Marquardt non-linear least squares determination. The technology allows for the extraction of distance measurements, including vertical ranges based on slant ranges measured from the profiler to the closest points on the targeted objects. In some embodiments, the sub-bottom profiler is mounted on an unmanned underwater vehicle equipped with thrusters, enabling it to navigate toward the targeted area for excavation and sidescan of the objects.
