ALEXANDRIA, Va., Dec. 16 -- United States Patent no. 12,499,771, issued on Dec. 16, was assigned to THALES (Courbevoie, France).

"System and method for fast and reliable detection of the complexity of air sectors" was invented by Andrei Purica (Rungis, France) and Beatrice Pesquet-Popescu (Rungis, France).

According to the abstract* released by the U.S. Patent & Trademark Office: "In the field of air traffic control, a method is provided to determine a processing complexity of an ATC situation. For this purpose, the method includes grouping parameters of the paths by pairs of paths in a matrix, applying to this matrix a transformation aiming to concentrate the energy, then calculating the complexity index of the ATC situation as a functio...
