Problem partitioning method and system

Abstract: In a problem partitioning method for problem solving in a computer system, a definition of a system to be controlled, a hierarchical control structure definition, problem definitions for a plurality of control nodes in the hierarchical control structure, and a structure evaluation function are used in partitioning the system problem. The partitioning method defines an instantiation of the hierarchical control structure by decomposing the system into a plurality of hierarchical control structure instances, with each control structure instance having a plurality of control levels. The performance of each of the hierarchical control structure instances is evaluated with the structure evaluation function and an optimal hierarchical control structure instance is selected.

Device having a state dependent upon the state of particles dispersed in a carrier

Abstract: A device that includes a layer of material having particles dispersed therein, a first electrode on a first surface of the layer, and a second electrode on a second surface of the layer opposite the first surface. A state of the particles is changed when a prescribed voltage is applied across the first and second electrodes.

Distributed actuation allocation for large assemblies of implementation units

Abstract: Apparatus and methods that approximately solve an actuation allocation problem by breaking the solution into modules, which may or may not be overlapping The solution to the actuation allocation problem is expressed in terms of solutions for each of the modules The solutions for the modules serve as constraints for a solution of the optimization problem on each module The optimization problem for each module is decomposed into further modules until the modules consist of a small enough number of individual implementation units so that the solution for the module can be solved using conventional optimization techniques

Large area storage display

Abstract: A large area display workstation provides a liquid crystal display, configured to produce an image. The electrical components of the liquid crystal display are disposed on a substrate through a large area fabrication technique. The workstation has a first, high-resolution video display, and the large area display is a second, lower-resolution file identification display. The computer displays a user-selected file in a high-resolution format on the high-resolution video display for manipulation, and displays a plurality of file indicators in a low-resolution format on the large area display.

Non-volatile programmable memory device

Abstract: A memory cell includes a heating component that is connected to a voltage-breakdown component. The heating component is configured to accelerate the break-down of a voltage-breakdown component. Memory structures and methods for making them are also disclosed.
