Abstract: Systems and methods use cyclical propellers with dynamic blade angle control to extract power from waves. A control system for such implementations can adapt pitching schedules for the blades of the cyclical propellers for efficient energy extraction and/or to control reactive forces. The cyclical propellers may be installed on the floor of a body of water or other liquid, on a submarine, or on a surface float, and blades may extend vertically or horizontally depending on the character of the waves. Several cyclical propellers can be combined into a single unit operated to minimize net reactive force or torque, to propel the unit horizontally or vertically, and/or to stabilize the unit. Such units can be installed with minimal or no moorings.

Abstract: A process of operating a memory array includes performing all volatile and nonvolatile operations on an nvDRAM cell array via a single data interface and using only DRAM-level signals on the data interface.

Abstract: A memory circuit includes a single transistor storing both volatile and nonvolatile bit charges.

Abstract: A memory circuit includes a high voltage region providing storage of a nonvolatile bit, and a low voltage region providing at least partial storage of a volatile bit. The high and low voltage regions are isolated from one another and formed by a plurality of transistors in series between a current source and a bit line.

Abstract: A method of operating a nonvolatile memory circuit having a plurality of transistors arranged in series between a voltage/current source node and recall sink node includes asserting a gate bias on an isolation transistor between the source node and a charge storage transistor during nonvolatile STANDBY.

Abstract: The invention relates to a method for the production of both MOS transistors with extremely low leakage currents at the pn junctions and logic/switching transistors, whose gates are laterally defined by spacers in a p-substrate or a p-well in an n-substrate. The aim of the invention is to provide a method for the production of MOS transistors with extremely low leakage currents that allows for parallel logic/switching transistors.

Abstract: A memory cell array includes reference cells each associated with a plurality of data cells of the array.

Abstract: A propeller having one or more blades eccentrically mounted to a shaft dynamically changes the blade pitch to produce free vortices in a fluid. For extracting energy from a moving fluid, the fluid flow acting on the blades rotates the propeller, while the pitch changes create a fluid flow pattern known as a von Karman vortex street. The resulting time averaged flow field distant from the propeller is a wake flow, and the energy of the fluid flow can be efficiently converted to rotation of a shaft driven device. For propulsion, applied shaft rotation and the dynamic pitch change in a fluid together create a flow pattern that is the inverse of the von Karman vortex street. For either energy extraction or propulsion, the propeller is particularly suited for low flow speeds, where the effects of low Reynolds number induced flow separation on blades may make other propellers inefficient.
