Abstract:
A processor architecture is described which operates with improved computational efficiency using instruction fetching functions that are decoupled from instruction execution functions by a dynamic register file. The instruction fetching function operates in free-running mode which does not stop if a fetched instruction cannot be executed due to data being unavailable or due to other instruction dependencies. Branch instructions are taken in a predicted direction and the results of execution of all instructions are provisionally stored pending validation or invalidation on the basis of the dependencies becoming available later. For branches of executed instructions that are later invalidated, the results of the executed instructions are flushed from provisional storage and the initial instruction which previously executed at the beginning of a branch on predicted dependencies is re-executed on the actual data that subsequently became available, and all subsequent instructions in such branch are also re-executed on the basis of dependencies actually available from execution of previous instructions in such branch.
Abstract:
A color-tunable, reflective, paper-like display utilizes the unique optical properties of nano-engineered metal and metal-dielectric composite structures that exhibit a plasmon resonance. By changing the dielectric properties of a medium in which these structures are embedded, or by changing the spatial relationship of these structures, their optical absorbance and scattering spectra can be tuned. This enables simpler pixel architectures with better performance than is possible with fixed-color technologies. Low power video rate operation can be achieved in a paper-like display.
Abstract:
Certain embodiments of the present invention are directed at data storage devices capable of storing, reading and writing data to storage areas of nanometer dimensions. Certain embodiments are directed at devices wherein a fluid medium and particles are provided between a storage medium and an energy-emitting tip to channel energy from the tip to the storage medium. Certain embodiments are directed at devices wherein conductor molecules are attached to the surface of the storage medium and channel energy to the storage medium from an energy-emitting tip. Certain embodiments of the present invention are directed at methods of reading and writing to a storage medium by making use of intermediate particles and/or molecules to channel beams from a tip to a storage medium where data is stored.
Abstract:
A low energy charged particle detector having a diode with a first layer and a top layer physically coupled to the first layer. The intersection between the first layer and the top layer defines a junction. The top layer is composed of a two-dimensional material such as a chalcogen-based material, providing an electrically passivated exposed outer surface opposite to the junction. The outer surface is exposed to receive low-energy charged particles from external sources. An appropriate control circuit is coupled to the diode, and operable to recognize the incidence of a particle upon the outer surface as a change in current or voltage potential.
Abstract:
A method of manufacturing an electronic-charge-transferring device includes providing a charged species source and a charge species drain and providing a movable component for transferring charge to the charged species drain. A first protrusion proximate to the moveable component and a second protrusion proximate to the moveable component are also provided. The moveable component is positioned in close proximity to the charged species source, and at least one of the moveable component, the first protrusion and the second protrusion is of a micrometer scale or smaller.
Abstract:
A data storage unit includes a data storage layer with multiple storage areas having a storage medium disposed thereon that changes between a plurality of states for writing and reading information. An array of beam emitters, such as laser light probes or near-field light sources, are spaced in close proximity to the data storage layer. A layer (LASL) adjacent to the storage layer generates carriers (electrons, holes or photons) in response to the light beams. Data is read by directing a light beam onto the data storage layer. The storage medium on the data storage layer affects the generation of carriers or alters the transport of carriers after generation by the LASL, depending upon the state of the storage medium. The carriers are detected in a detection region in carrier communication with the LASL to detect the presence of data. The detection region may comprise any type of region for detecting carriers, including a semiconductor diode junction and a photoconductive region. The presence of data in the storage areas is determined by the number of carriers transported across the semiconductor junction or the number of carriers transported in the photoconductive regions between electrodes.

Abstract:
A method of forming an electrical interconnect, which includes a first electrode, an interlayer of a programmable material disposed over at least a portion of the first electrode, and a second electrode disposed over the programmable material at a non-zero angle relative to the first electrode. The interlayer includes a modified region having differing electrical properties than the rest of the interlayer, sandwiched at the junction of the first electrode and the second electrode. The interlayer may be exposed to a focused beam to form the modified region.

Abstract:
A tagging system contains first taggants and second taggants. The taggants differ from each other so that the first taggants have a first emission spectrum and a first absorption edge and the second taggants have a second emission spectrum and a second absorption edge. In the tagging system, the first taggants are arranged to be within an interaction distance of the second taggants so that energy transfer between the first taggants and the second taggants causes an emission spectrum of the tagging system to differ from a sum of the first emission spectrum and the second emission spectrum.
