Abstract: Improved prosthetic valves, their methods of manufacture, and systems and devices for manufacturing the valves are described. The prosthetic valves can be configured for transcatheter implantation. The prosthetic valves can have artificial leaflets. The prosthetic valves can be manufactured in numerous ways, such as by polymeric dipping processes and/or electrospinning. Sponge-like polymers for valves and other medical devices are also disclosed.

Abstract: A system and method for controlling a multi-rotor aircraft that implements the unconventional use of an odd number of rotors. The odd or auxiliary rotor is designed to be smaller in diameter than the remaining main rotors and accordingly generates a smaller unbalanced torque and pitch on the aircraft. Additional configurations implement the use of smaller thrust rotors that can be used to generate thrust as well as control yaw and thus counteract any remaining unbalanced torque from the odd auxiliary rotor.

Abstract: A system and method for controlling a multi-rotor aircraft that implements the unconventional use of different sized rotors. The different sized rotors than the main rotors tend to generate an unbalanced torque and pitch on the aircraft that effectively decouples the pitch and yaw control from the main rotors. The atypical design tends to lend itself to improved control capabilities and simplified control systems. Additional configurations implement the use of smaller thrust rotors that can be used to generate thrust as well as control yaw and thus counteract any remaining unbalanced torque from the odd auxiliary rotor.

Abstract: A system and method for improving the flight control and efficiency of an aerial vehicle. Many embodiments are directed to a rotor-shroud assembly system where a plurality of rotor blades are connected to the internal side of a shroud and are set up to pivot through the use of a pitching mechanism. The entire assembly is configured to rotate when attached to a motor.

Abstract: A system and method for estimating the shear wall stress of an aerodynamic surface using a tuft visualization technique combined with a physics-informed neural network. The tuft visualization technique is a simplified method of generating velocity profile data of an aerodynamic model that can subsequently be used to generate a shear wall stress profile of the model. Systems and methods described herein also provide for additional input data using an augmented tuft and taps inputs for the physics-informed neural network to generate the shear wall stress profile.
