Abstract:
A method and system for identifying a defect or contamination on a surface of a material. The method and system involves providing a material, such as a semiconductor wafer, using a non-vibrating contact potential difference sensor to scan the wafer, generate contact potential difference data and processing that data to identify a pattern characteristic of the defect or contamination.

Abstract:
The present invention is a method that enables a business with multiple locations within a LATA to use a single number for its service. All callers dial the same number to reach the subscriber's business, and a network routes the calls to the most appropriate subscriber location based on the geographic location of the caller, time of day, day of week, and/or percent distribution among subscriber locations. The geographic location of the caller is determined using the calling party number (NPA-NXX-XXXX) and either mapping this number to a wire center (using the NPA-NXX) or to a block group (using the entire NPA-NXX-XXXX). An advantage of Area Number Calling is the granularity of block group routing. Block groups are defined by the Census Bureau and typically encompass a much smaller geographic area than a wire center. Block groups are defined by the Census Bureau for the entire United States.
