Abstract: A spacecraft control architecture uses a multi-joint robotic arm carrying a reflective panel to generate controllable forces and torques from solar radiation pressure and, in some cases, aerodynamic drag. A plurality of attachment points on an exterior surface provide mechanical and electrical interfaces for end effectors of the arm. A control system determines a demanded change in stored momentum and/or orbital state, computes available external forces based on ephemeris and attitude data, and evaluates candidate arm and panel configurations subject to joint limits and keep-out regions for antennas, sensors, and solar wings. The control system selects a target configuration and commands the arm to walk between attachment points by alternately latching and unlatching the end effectors while maintaining at least one latched interface. The architecture can also place the panel in a stowed configuration that produces substantially zero net force and torque.

Abstract: Embodiments of the present invention implement a method, apparatus, and computer-readable medium for the use of a robotic arm for momentum unloading and orbit control. In some instances, a panel is attached to the end of a robotic arm. It is positioned, in angle and position, to optimize unloading. The robot arm can move about the spacecraft, giving additional degrees of freedom. The panel can be stowed when necessary.

Abstract: A wearable knee brace system integrates inertial measurement unit (IMU) and electromyography (EMG) sensors with machine learning models to prevent anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) injuries. The system collects real-time biomechanical and neuromuscular data and analyzes the data using supervised, personalized, or federated learning techniques to identify high-risk movement patterns. Upon detecting elevated injury risk, the system may issue real-time alerts or activate a hybrid actuation system comprising high-force, low-displacement actuators and low-force, high-displacement actuators to reduce joint loading. The system further supports personalized model adaptation using calibration activities and transfer learning, as well as privacy-preserving performance improvements through federated learning. Feedback is provided through visual, auditory, or haptic interfaces and may be integrated with rehabilitation tools or mobile applications.
