Patent number: 11934205Abstract: Methods and devices for optimizing the climb of an aircraft or drone are provided. After an optimal continuous climb strategy has been determined, a lateral path is determined, in particular in terms of speeds and turn radii, based on vertical predictions computed in the previous step. Subsequently, computation results are displayed on one or more human-machine interfaces and the climb strategy is actually flown. Embodiments describe the use of altitude and speed constraints and/or settings in respect of speed and/or thrust and/or level-flight avoidance and/or gradient-variation minimization, and iteratively fitting parameters in order to make the profile of the current path coincide with the constrained profile in real time depending on the selected flight dynamics (e.g. energy sharing, constraint on climb gradient, constraint on the vertical climb rate). System (e.g. FMS) and software aspects are described.Type: GrantFiled: November 13, 2020Date of Patent: March 19, 2024Assignee: THALESInventors: Johan Boyer, Geoffrey Durand, Jérôme Sacle

Patent number: 11740366Abstract: GPS-based position reporting suffers from probabilistic error. The system and methods discussed herein reduce uncertainty by mapping a geometric figure that encompasses a GPS-based reported location and that bounds corresponding predetermined-as-more-probable true locations (MPTL's) among possible locations for the source of the reported location. The mapped figure is overlaid on a relatively accurate mapping of substantially adjacent polygonal areas. Areas of overlap are used for picking among the areas, the polygonal area most likely to be occupied by the source. In one embodiment, the polygonal areas are closely packed parking spots in a parking lot, garage or other like structure, the source is a customer's mobile phone and an attendant is tasked with quickly delivering ordered goods to the customer's parking spot.Type: GrantFiled: May 20, 2020Date of Patent: August 29, 2023Assignee: Radius Networks, Inc.Inventors: David Helms, Marc Wallace, Scott Yoder, Christopher Sexton
