Patent number: 12093060Abstract: A vehicle and method of control comprising generating a geometric control envelope in a geometric space of operation points defined by a number of control aspects, the envelope having vertices representing maximum values of the control aspects, and determining a desired operation point in the geometric space representing a control input. Further, the method includes if the desired operation point is outside the envelope, scaling up a first one of the control aspects by a first factor, determining an effective operation point in the envelope geometrically closest to the desired operation point, scaling down all of the control aspects by a second factor inverse of the first factor, and instructing the propulsion mechanisms to propel the vehicle according to the effective operation point.Type: GrantFiled: January 31, 2022Date of Patent: September 17, 2024Assignee: Digital Aerolus, Inc.Inventors: Jeffery J. Alholm, John C. Blessing, Jacob B. Davisson, Thomas D. Williams

Patent number: 11853082Abstract: A method and system for controlling movement of a vehicle. Movement, orientation, and position data of the vehicle is collected. A model of kinematics of the vehicle and its environment is created and a Theory of World model is produced and updated. The model includes geometric algebra multivectors. Errors and noise are stored as geometrically meaningful first-class objects within the multivectors. Geometric algebra operations are used to manipulate the model during operation. Error and noise data are propagated and manipulated using geometric algebra operations to reflect measurement and processing errors or noise. The models are used in generation of control data with a primary intent of ensuring stability. Operations such as intersections are used to compare position, orientation, and movement of the vehicle against position, orientation, and movement of objects in its environment. System tasks include, but are not limited to, kinematics, inverse kinematics, collision avoidance, and dynamics.Type: GrantFiled: February 22, 2022Date of Patent: December 26, 2023Assignee: Digital Aerolus, Inc.Inventors: Ian J. McEwan, Thomas D. Williams, Jeffery J. Alholm, John C. Blessing, Jacob B. Davisson, Frank C. Glazer, Jay D. Manifold, Laurence R. Williams

Patent number: 10840785Abstract: Methods of assembling motor windings comprising wrapping windings around a central longitudinal axis in a cylindrical shape having a plurality of annularly spaced positions such that the windings form “n” and/or “u” shapes around the positions. As the windings encircle the longitudinal axis, they are wrapped in an outward spiral or inward spiral such that each pass of the windings is stacked on a previous pass.Type: GrantFiled: November 8, 2017Date of Patent: November 17, 2020Assignee: Digital Aerolus, Inc.Inventor: Ian J. McEwan

Patent number: 10338556Abstract: A system and method of describing and executing autonomous or autonomous device behaviors via a computer-implemented system incorporating a fuzzy language, a simulator, and one or more runtimes. The fuzzy language combines high level behaviors and produces a set of parameter descriptions. The parameter descriptions are behavior characteristics whose values are not yet necessarily known or selected. The parameter descriptions are used via simulation to find relevant parameters and acceptable parameter values that result or will result in the autonomous or semi-autonomous device behaving as desired.Type: GrantFiled: November 8, 2017Date of Patent: July 2, 2019Assignee: Digital Aerolus, Inc.Inventors: Thomas D. Williams, Ian J. McEwan, Jeffery J. Alholm
