  • Patent number: 7512306
    Abstract: The invention provides a fiber pigtail assembly wherein a polarization maintaining fiber is soldered directly to a mounting pad without a sleeve or a ferrule therebetween. A portion of the polarization maintaining fiber near a fiber end is embedded in a vertical slow axis orientation within an asymmetrical solder ball having a flat portion for adhering to the mounting pad. The vertical slow axis orientation of the polarization maintaining fiber within the solder ball enhances power stability and polarization extinction ratio properties of optical modules utilizing the invention.

  • Publication number: 20090067454
    Abstract: The invention relates to a fiber laser and harmonic frequency conversion module incorporating a 90 degree Polarization Maintaining (PM) fiber fusion splice therebetween for providing temperature insensitive power stabilization. The present invention has found that incorporating at least one 90 degree splice of the transmission axes of the PM fiber, coupling a fast axis to a slow axis, to create substantially equal optical path lengths of the two transmission axes of the fiber coupling can nearly eliminate output amplitude fluctuation within a practical operating temperature range.

  • Publication number: 20070283000
    Abstract: A method for detection of phishing attempts in received electronic mail messages includes retrieving the source code, displayed text, and a list of all specified addresses contained within the source code of a received electronic message. Visual character normalization is applied to each specified address to develop all possible address combinations and to form a normalized address list. The specified addresses are removed from the normalized address list to create a revised address list, upon which comparison tests are performed to determine if each address in the revised address list is from a valid source. The recipient of the electronic message is informed of any message found to be from an invalid source.

  • Patent number: 7133862
    Abstract: A system for enriching document content using enrichment themes includes a directed search service and an import-export service. The directed search service allows users to author documents while querying information providers using the directed searches that are inserted as part of the authored documents. The import-export service enables meta-document exchanges between systems that provide document enrichment by binding imported meta-documents to identical or similar information providers.
