Patent number: 11969522Abstract: The present disclosure describes the use of immune modulators to promote nerve growth and regeneration, particularly in the context of nerve deficit stemming from trauma and disease. In particular, the disclosure provides for the use of CXCR4 antagonsists, STAT3 activators, and an agent that increase nitric oxide, alone or in combination, to treat nerve deficit conditions.Type: GrantFiled: July 7, 2020Date of Patent: April 30, 2024Assignees: The Board of Regents of the University of Texas SystemInventors: Jonathan Cheng, Edward Keefer, Srikanth Vasudevan

Patent number: 11821713Abstract: A projectile incorporates one or more spoiler-tabbed spinning disks to effect flow around the projectile and thus impart steering forces and/or moments. The spoiler tabs may be deployed only during steering phases of travel thus minimizing the drag penalty associated with steering systems. The disks are driven by motors and informed and controlled by sensors and electronic control systems. The spoiler tabs protrude through the surface of the projectile only for certain angles of spin of the spinning disk. For spin-stabilized projectiles, the disks spin at substantially the same rate as the projectile, but the disks may function in fin-stabilized projectiles as well. Any number of such spinning flow effector disks may be incorporated in a projectile, with the manner of functional coordination differing slightly for even and odd numbers of disks.Type: GrantFiled: June 11, 2021Date of Patent: November 21, 2023Assignee: Orbital Research Inc.Inventors: Zak Sowle, Srikanth Vasudevan, Matthew C. Birch

Patent number: 11525655Abstract: Methods involve using a guided munition (e.g., a mortar round or a grenade) that utilizes deployable flow effectors, activatable flow effectors and/or active flow control devices to extend the range and enhance the precision of traditional unguided munitions without increasing the charge needed for launch. Sensors such as accelerometers, magnetometers, IR sensors, rate gyros, and motor controller sensors feed signals into a controller which then actuates or deploys the flow effectors/flow control devices to achieve the enhanced characteristics.Type: GrantFiled: May 20, 2021Date of Patent: December 13, 2022Assignee: Orbital Research Inc.Inventors: Srikanth Vasudevan, Paul Suchy, Matthew C.

Patent number: 10011344Abstract: An improved high-voltage AC power supply energizes and regulates plasma actuators for aerodynamic flow control. Such plasma actuators are used, for example, on aerodynamic surfaces, wind turbine blades, and the like for vehicle control, drag or noise reduction, or efficient power generation. Various embodiments of the power supply are small, compact, lightweight, portable, modular, self-contained in its own housing, easily replaceable and swappable, autonomous, self-cooling, and/or gangable in series or parallel to provide any desired control authority over the selected surface. In some embodiments, the parameters for the plasma electronics can be manually selected and pre-programmed for a specific application, while in preferred embodiments, the plasma electronics can automatically identify the appropriate parameters and self-tune the performance of the plasma actuators.Type: GrantFiled: December 31, 2010Date of Patent: July 3, 2018Assignee: Orbital Research Inc.Inventors: Srikanth Vasudevan, Frederick J.
