  • Metallic gratings and measurement methods thereof
    Patent number: 10883924
    Abstract: There is set forth herein in one embodiment, a structure including a metallic grating having a grating pattern, the metallic grating including a critical dimension. The metallic grating can output a spectral profile when exposed to electromagnetic radiation, the spectral profile having a feature. The grating pattern can be configured so that a change of the critical dimension produces a shift in a value of the feature of the spectral profile. A method can include propagating input electromagnetic radiation onto a metallic grating having a two dimensional periodic grating pattern and measuring a critical dimension of the metallic grating using output electromagnetic radiation from the metallic grating.

  • CCXML/Voice XML browser to implement an AIN intelligent peripheral with call handling functionality
    Publication number: 20050249191
    Abstract: A method and structure for the invention forwards a request for voice instructions from the XML browser to a call control protocol to CCXML/Voice XML converter. The invention converts the request for voice instructions to the call control protocol using the converter and forwards the request for voice instructions from the converter to the control point. The control point returns voice instructions to the converter, and the converter, in turn, converts the voice instructions from the call control protocol to CCXML/Voice XML. This process next returns voice instructions from the converter to the CCXML/Voice XML browser and the XML browser executes the voice instructions using the XML browser. Then, the invention runs an application on a CCXML application server connected to said CCXML/Voice XML browser.
