• articulated airfoils
• transducer
• "trap and release" effect        trap-and-release effect
• "synchronized motion of opposing blades in reciprocating fashion, analogous to the operation of the internal combustion engine, rather than the random "flutter" effect"
• "none of these suggest use of interleaved arrays of blades translating cyclically in opposition in response to the flow of the motive medium while subject to the explicit control of blade tilts."
• "plunging and soaring"
• "applied torque"
• "two interleaved arrays of airfoils or hydrofoils, or flat panels ("blades") which ascend and descend cyclically in opposition, and are linked to a shared horizontal axis crankshaft."
• "valve-like (pneumatic) effect"
• "passive exoskeleton framework for the land-based embodiments"
• "topside buoyancy and bottom-side ballast"  for the water embodiments
• "linear excursions"   "linearly rise"    linearly fall"
• "thrust rods"
