Hybrid terrain-adaptive lower-extremity systems

This invention describes a smart prosthetic leg system designed to automatically adjust how it works based on the ground a person is walking on. It uses a special sensor, called an inertial measurement unit (IMU), which includes a gyroscope and accelerometer, placed on the lower part of the prosthetic leg. This sensor helps the leg detect things like how fast it's moving and its orientation, allowing the system to then change its behavior to better handle different surfaces, from smooth to rough or slippery.

Why it matters: Filed before significant advancements in embedded AI and machine learning for real-time sensor data processing. These technologies could now make the complex terrain detection and adaptive control more robust and efficient than previously possible.
