  • Publication number: 20070046938
    Abstract: A particle detection system uses a reflective optic comprising a curved surface to detect high angle scattered light generated by a particle in a liquid medium, when a laser beam is incident on the particle. When the particles transit the laser beam, light is scattered in all directions and is described by MIE scattering theory for particles about the size of the wavelength of light and larger or Rayleigh Scattering when the particles are smaller than the wavelength of light. By using the reflective optic, the scattered light can be detected over angles that are greater than normally obtainable.

  • Publication number: 20070040235
    Abstract: The present invention provides a semiconductor structure in which different types of devices are located upon a specific crystal orientation of a hybrid substrate that enhances the performance of each type of device. In the semiconductor structure of the present invention, a dual trench isolation scheme is employed whereby a first trench isolation region of a first depth isolates devices of different polarity from each other, while second trench isolation regions of a second depth, which is shallower than the first depth, are used to isolate devices of the same polarity from each other. The present invention further provides a dual trench semiconductor structure in which pFETs are located on a (110) crystallographic plane, while nFETs are located on a (100) crystallographic plane. In accordance with the present invention, the devices of different polarity, i.e., nFETs and pFETs, are bulk-like devices.

  • Patent number: 7174508
    Abstract: Pages are provided in response to a request from a browser received by a server. The server obtains an adapted page, based on a template page, from a display infrastructure. The display infrastructure uses a template page identifier obtained from a resolution component. The resolution component obtains template page identifiers by matching attributes relating to the page request with attributes associated with template page identifiers stored in a database. The template page identifiers are provided based on the best match of the template page attributes and the page request attributes, with default values being used and a defined ranking being used where multiple matched template pages exist.

  • Publication number: 20060291866
    Abstract: Systems and methods for use with an optical communication beam are disclosed. The system allows the beam of light to operate at an adequate power level that provides a robust optical link while minimizing any safety risk to humans. The system calibrates and controls the gain for an avalanche photodiode detector (APD). A detector circuit is used to calibrate the APD. Once calibrated, the detector circuit further provides an electrical bias to the APD to process or condition the electrical signal to produce a detector output. The systems and methods disclosed herein attenuate the power level of an incoming communication beam to prevent oversaturation of an APD. The system further provides an alignment signal, which is effective over a wide dynamic range of incoming power levels.

  • Publication number: 20060228848
    Abstract: Methods of fabricating a semiconductor device including a dual-hybrid liner in which an underlying silicide layer is protected from photoresist stripping chemicals by using a hard mask as a pattern during etching, rather than using a photoresist. The hard mask prevents exposure of a silicide layer to photoresist stripping chemicals and provides very good lateral dimension control such that the two nitride liners are well aligned.

  • Publication number: 20060109285
    Abstract: The invention is directed to an apparatus and method for writing a non-rectangular frame to a display device and for animating window transitions. The apparatus comprises a memory for storing at least one parameter for defining a first aperture boundary and a data selecting part. The data selecting part is adapted for comparing the associated coordinates of each datum of a first frame to the first boundary, determining if a first condition is true, and processing each first-frame datum for which the condition is true. The method comprises defining a first aperture boundary, comparing the associated coordinates of each datum of a first frame to the first boundary to determine if a first condition is true, and for each first-frame datum for which the condition is true, processing the first-frame datum. By repeatedly selecting image data for processing, the animation of window transitions may be achieved.

  • Publication number: 20060074806
    Abstract: A technique is provided to generally provide user support across multiple accounts by allowing a single person or user to represent multiple organizations. An embodiment may typically provide support for a user to act on behalf of an account in the form of a virtual persona and also to provide the ability to manage the assignment of access rights allowing only prescribed privileged users to act on behalf of an account. This may then be accomplished through registration of a single identity for the user or person on the system, while allowing that person to then select the desired organization to represent for a particular session (which will be stored in the user's session).

  • Publication number: 20060040497
    Abstract: Stress level of a nitride film is adjusted as a function of two or more of the following: identity of a starting material precursor used to make the nitride film; identity of a nitrogen-containing precursor with which is treated the starting material precursor; ratio of the starting material precursor to the nitrogen-containing precursor; a set of CVD conditions under which the film is grown; and/or a thickness to which the film is grown. A rapid thermal chemical vapor deposition (RTCVD) film produced by reacting a compound containing silicon, nitrogen and carbon (such as bis-tertiary butyl amino silane (BTBAS)) with NH3 can provide advantageous properties, such as high stress and excellent performance in an etch-stop application. An ammonia-treated BTBAS film is particularly excellent in providing a high-stress property, and further having maintainability of that high-stress property over repeated annealing.

  • Publication number: 20060038830
    Abstract: A system and method for continuously tracing transfer rectangles for performing image data transfers includes a display controller with control logic, a rectangle module, and a coordinates module. The rectangle module detects write operations to on-screen data in a video memory, and then updates a primary transfer rectangle during a normal mode to include pixel data from the foregoing write operations. The coordinates module stores the primary transfer rectangle for performing a current transfer operation. The coordinates module enters a pause mode before initiating the current transfer operation, and retains the primary transfer rectangle during the pause mode. The coordinate module also stores a secondary transfer rectangle formed during the pause mode by detecting the foregoing write operations. The controller logic instructs the coordinates module to resume the normal mode after the current transfer operation concludes.
