  • Publication number: 20070026590
    Abstract: A device for regulating a flow of electric current and its manufacturing method are provided. The device includes metal-insulator-semiconductor source-drain contacts forming Schottky barrier or Schottky-like junctions to the semiconductor substrate. The device includes an interfacial layer between the semiconductor substrate and a metal source and/or drain electrode, thereby dynamically adjusting a Schottky barrier height by applying different bias conditions. The dynamic Schottky barrier modulation provides increased electric current for low drain bias conditions, reducing the sub-linear turn-on characteristic of Schottky barrier MOSFET devices and improving device performance.

  • Patent number: 7117213
    Abstract: Failover processing that accommodates failures of backup computing nodes and resources, such as data storage units and printers. Failure of a computing node that controls resources causes another computing node to assume control of the resources controlled by the failed node. Failure of the primary computing node causes another computing node, at either the same or at a different site, to be selected as the new primary node. Failure of a resource at the primary site causes the site with the next highest priority backup resource to become the new primary site. Failure of a backup computing node causes a new backup node at the same site as the failed backup node to replace the failed backup node as host for the site's resources. Backup mirroring data flows are then adjusted to reflect the new functions of the affected nodes.

  • Publication number: 20060214931
    Abstract: Computer graphics image rendering techniques render images using a precomputed radiance transfer (PRT) to model local effects such as bumps, wrinkles, or other detailed features on an arbitrarily deformable model's surface. The techniques apply zonal harmonics (ZH) which approximate spherical functions as sums of circularly symmetric functions around different axes. By spatially varying both the axes and coefficients of these basis functions, approximations can fit to spatially varying transfer signals. Compared to the spherical harmonic (SH) basis, the ZH basis yields a more compact approximation, and can be rotated at a low computational expense suitable for dense per-vertex or per-pixel evaluation. This allows PRT to be mapped onto deforming models which re-orient the local coordinate frame.

  • Publication number: 20050253844
    Abstract: Systems and methods are provided for providing a fine-to-coarse look ahead in connection with parametrization in a graphics system. The use of a variety of parametrization metrics may be supplemented and improved by the fine-to-coarse look ahead techniques of the invention. First, the metric of a parametrization is minimized using a coarse-to-fine hierarchical solver, and then accelerated with a fine-to-coarse propagation. The resulting parametrizations have increased texture resolution in surface regions with greater signal detail at all levels of detail in the progressive mesh sequence.

  • Publication number: 20050225550
    Abstract: Systems and methods are provided for optimizing a parametrization scheme in accordance with information about the surface signal. A surface parametrization is created to store a given surface signal into a texture image. The signal-specialized metric of the invention minimizes signal approximation error, i.e., the difference between the original surface signal and its reconstruction from the sampled texture. A signal-stretch parametrization metric is derived based on a Taylor expansion of signal error. For fast evaluation, the metric of the invention is pre-integrated over the surface as a metric tensor. The resulting parametrizations have increased texture resolution in surface regions with greater signal detail. Compared to traditional geometric parametrizations, the number of texture samples can often be reduced by a significant factor for a desired signal accuracy.

  • Patent number: 6931164
    Abstract: A waveguide device is provided comprising an optical waveguide core and a cladding optically coupled to the optical waveguide core. The cladding comprises an optically functional region defining a refractive index that is configured to vary in response to a control signal applied to the optically functional region.

In accordance with one embodiment of the present invention, the optically functional region may be characterized as a Kerr Effect medium.

  • Publication number: 20050151733
    Abstract: Techniques and tools for mesh processing are described. For example, a multi-chart geometry image represents arbitrary surfaces on object models. The multi-chart geometry image is created by resampling a surface onto a regular 2D grid, using a flexible atlas construction to map the surface piecewise onto charts of arbitrary shape. This added flexibility reduces parameterization distortion and thus provides greater geometric fidelity, particularly for shapes with long extremities, high genus, or disconnected components. As another example, zippering creates a watertight surface on reconstructed triangle meshes. The zippering unifies discrete paths of samples along chart boundaries to form the watertight mesh.

  • Publication number: 20050118793
    Abstract: A method of fabricating a transistor device for regulating the flow of electric current is provided wherein the device has Schottky-barrier metal source-drain contacts. The method, in one embodiment, utilizes an isotropic etch process prior to the formation of the metal source-drain contacts to provide better control of the Schottky-barrier junction location to a channel region. The improvements from the controllability of the placement of the Schottky-barrier junction enables additional drive current and optimizes device performance, thereby significantly improving manufacturability.
