20110130895 | METHOD OF OBTAINING A LOCAL TERRAIN ELEVATION DATABASE FROM DETECTOR MEANS ON BOARD A VEHICLE - A method essentially comprising a step of storing each plot mesh. Each plot mesh receiving plots sent thereto by detector means and retaining in memory at least the altitude of the highest plot and the number of plots neighboring said highest plot in said mesh. The altitude and the number of plots neighboring are updated each time a new plot is sent to the plot mesh. A step of rejecting plot meshes is presenting a number of neighboring plots that is less than a predetermined rejection threshold value. The rejection threshold value is a function of the position of the mesh relative to the detector means. A step is preparing the local terrain elevation database from the plot meshes (M(i,j)) that are not rejected. | 06-02-2011 |
20110144942 | METHOD OF USING TELEMETRY TO DETECT AT LEAST ONE SUSPENDED THREADLIKE OBJECT, THE OBJECT LYING IN THE DETECTION FIELD OF A TELEMETER MOUNTED ON BOARD A VEHICLE - A method of detecting at least one suspended threadlike object by telemetry, the object lying in the detection field of a telemeter on board a vehicle. The method wherein in step iii), for each vertical plane taken into consideration, and for each set of at least four candidate points close to the vertical plane in question, using the least squares method to calculate the values of three parameters a, b, and c of a catenary having an equation of the form: | 06-16-2011 |

20150279219 | PROCEDURE FOR THE DETECTION AND DISPLAY OF ARTIFICIAL OBSTACLES FOR A ROTARY-WING AIRCRAFT - A procedure for the detection and display of the ground and of obstacles through the use of detection means installed onboard a vehicle, which detection means send measurement signals toward the ground and receive a plurality of elementary plots (Pe). The procedure makes it possible to create a grid of the ground along a horizontal plane, with each ground cell (Ms(i,j)) consisting of an elementary plot (Pe) having a minimum altitude Zmin(i,j)), and with each other elementary plot (Pe) corresponding to the ground cell (Ms(i,j)) and having a different altitude (Z | 10-01-2015 |
