Abstract: A system and method for generating an artificial topography in a distributed array of robotic agents. Each robotic agent stores, and periodically updates a parameter value or “A-value” in accordance with a process including, e.g., averaging neighboring A-values, received from close neighbor robotic agents, biasing the A-value based on external commands or measured environmental parameters, and decreasing the A-value by a cooling rate factor. Averaging among neighboring robotic agents results eventually in a globally smoothed distribution of A-values. A gradient may be estimated for the distribution of A-values, and the robotic agents may be programmed to move in the direction of the gradient, toward increasing A-values. This behavior may be employed to cause the robotic agents to follow a robotic agent with a fixed, relatively large, A-value, or, if the A-values are biased by features (e.g., gradients or steps) in environmental parameters, to converge on such features.

Abstract: A vehicle having a wing, a forward propeller configured for forward flight, and an aft propeller configured for submerged travel in a rearward direction. The vehicle center of mass is aft of its floating center of buoyancy, and center of mass and the floating center of buoyancy lie between the first and second propellers. The vehicle has a natural floating orientation in which the vehicle, while floating, has its first propeller located in the air and positioned for initiating airborne flight in a forward direction, and in which the vehicle has its second propeller located in the liquid and positioned for initiating submerged travel in a rearward direction.

Abstract: A series of helical Savonius turbine generators for use in the ocean, each turbine generator being an independent system, but all sharing a common mooring/bus-bar cable. An anchor connects one generator to the ocean floor, and a buoyancy device system buoys the turbines so that they can generate power from passing currents. The generators are coreless, and generate electrical or hydraulic power. The turbine blades rotate on bearings that are lubricated with ambient water. A control system separately tracks the power generation level of each turbine, and controls the buoyancy of the buoyancy device system.

Abstract: Twisted leaf shaped ceiling fan blades for low, medium and high speed operation of less than approximately 250 rpm. The novel blades twisted blades can be configured for 52?, 54?, 56?, 60? and 64? diameter fans, and have less blades (3 for example) than conventional flat type bladed fans having 4, 5 blades and have greater air flow and less power draw results than the conventional flat 54 inch fans. Any of the novel twisted blades of 48?, 52?, 54?, 56?, 60? and 64? can be run at reduced speeds, drawing less Watts than conventional fans and still perform better with more air flow and less problems than conventional flat type conventional leaf shaped blades.

Articulation capacity may have a path of resistance that guides the user into selected patterns of therapeutic motion.
