Publication number: 20150055922Abstract: The disclosure is directed to an all glass method that frustrates the internal reflection on the outside diameter of an optical fiber's glass cladding thus allowing the light to be directed to a light absorbing material/ medium and allowing the desired light in the core of the fiber to be preserved with no loss. The frustration is achieved by having at least one glass frustrater in glass-to-glass contact with the outermost cladding layer of the optical fiber. The glass frustrater is made of a glass that has a glass transition point lower that both the core and cladding glasses of the fiber. Chalcogenide and phosphate glasses are among the glasses suitable for this application.Type: ApplicationFiled: August 4, 2014Publication date: February 26, 2015Inventors: Brian McMaster, Daniel Staloff

Publication number: 20060100975Abstract: The subject invention provides a unique system and method that facilitates classifying UI components abstracted from a computer based application in a strongly-typed manner based at least in part from a strongly-typed class framework. Methods included in the strongly-typed classes within the framework can correspond to one or more UI components found in the application. The UI components can be abstracted out and then the closest match between a UI component and a strongly-typed class in the framework can be found. Classes in the framework can be modified to create new strongly-typed classes. Once the UI components are classified in a strongly-typed manner, code can be created, albeit a lesser amount of code than otherwise would be required since the new strongly-typed classes can be derived from the framework.Type: ApplicationFiled: October 25, 2004Publication date: May 11, 2006Applicant: Microsoft CorporationInventors: Brian McMaster, Eric Allen, William Bailey

Publication number: 20060100973Abstract: The subject invention provides a unique system and method that facilitates mitigating the number of versions of a coded application needed to accommodate different spoken languages. The invention involves generating resource tables including resource identifier-resource type pairs. Examples of resource types include strings, bitmaps, icons, menus, and the like. For instance, instead of coding the application with strings, the application is coded with resource identifiers. The strings corresponding to the resource identifiers can be extracted from a resource table and in particular, from a resource file. Before searching through resource files and subdirectories, a cache can be searched to determine whether the resource identifier-string was previously requested. Resource identifiers can be parsed and the relevant information taken therefrom to locate the corresponding strings. If not already in the cache, the resource identifier-string pairs can be cached in a hash table or other database.Type: ApplicationFiled: October 21, 2004Publication date: May 11, 2006Applicant: Microsoft CorporationInventors: Brian McMaster, Michael Eng
