A prosthetic foot assembly is disclosed. The assembly includes a pivoting ankle joint with a hydraulic system, a prosthetic foot connected to the distal side of the ankle joint, and, at the proximal side, the ankle joint includes a transducer with pyramid adaptor for attaching to a pylon. The ankle joint sensor provides data collection during the stance and optionally, the swing, phases of walking using, for example, strain gages and accelerometers. Also disclosed are methods for real-time feature extraction. Key parameters are captured to which are applied linear, fuzzy logic, neural net, or generic algorithms to determine current state (walking flat, uphill, downhill etc.) in real time and execute changes to the angle between the ankle and foot almost instantaneously based on those parameters.

A spacecraft. The spacecraft includes a rocket engine; a first stage connected to the rocket engine; and a payload stage connected to the first stage. The spacecraft also includes a payload structure inside the payload stage between a first compartment of the payload stage and a second compartment of the payload stage. The payload structure may be a single shell that has a corrugated shape such that an inside surface and an outside surface of the payload structure vary in shape to form the corrugations.
