With a total of 3 patents, DiFrancesco has demonstrated a commitment to advancing technology in his area of expertise.

Latest Patents

One of his latest patents is the "Atom-interferometric, stepped gravity gradient measuring system." This full-tensor gravity gradient measuring system is based on atom interferometry. Each axis in the three-axis measuring system is served by a different gravity gradiometer, which comprises three pairs of atom interferometric accelerometers. The accelerometers in each pair are mounted on opposite sides of the gradiometer's rotation axis. The three AI accelerometer pairs are step-rotated, providing enhanced signal-to-noise performance. The overall measuring system is mounted orthogonally on a local-level platform, achieving a full-tensor measuring system. This innovative approach allows for improved results at lower costs compared to prior-art techniques.

Another significant patent is the "System and process for optimizing gravity gradiometer measurements." This patent focuses on optimizing gravity gradient measurements taken by an accelerometer-type gradiometer. By tilting the measuring plane of the instrument at selected angles above and below the horizontal, data can be processed to remove instrument bias. Additionally, data is taken at first and then at a second orthogonal azimuth heading to obtain absolute non-relative gradient measurements.
