Publication number: 20130064509Abstract: An optical fiber connector apparatus may include a ferrule having a hollow through its center. The hollow is sized and shaped to receive an optical fiber such that an end of each of the optical fiber is located at an endface of the ferrule. The endface of the ferrule is partitioned into a first section and a second section. The first section is perpendicular to an axis of the ferrule and the second section is angled with respect to the first section. When the connector is assembled, the ferrule can butt couple to a similarly configured second ferrule such that the perpendicular second portions of the endfaces of the ferrules are physically touching. The angle of the angled portions sets a distance between portions of the endfaces corresponding to endfaces of optical fibers received in the ferrules thereby setting a gap between the fiber endfaces.Type: ApplicationFiled: September 9, 2011Publication date: March 14, 2013Applicant: Mobius Photonics, Inc.Inventors: MARK W.

Publication number: 20100270505Abstract: The present invention provides several variations for converting biomass, and other carbon-containing feedstocks, into syngas. Some variations include pyrolyzing or torrefying biomass in a devolatilization unit to form a gas stream and char, and gasifying the char. Other variations include introducing biomass into a fluid-bed gasifier to generate a solid stream and a gas stream, followed by a partial-oxidation or reforming reactor to generate additional syngas from either, or both, of the solid or gas stream from the fluid-bed gasifier. Hot syngas is preferably subjected to heat recovery. The syngas produced by the disclosed methods may be used in any desired manner, such as conversion to liquid fuels (e.g., ethanol).Type: ApplicationFiled: April 21, 2010Publication date: October 28, 2010Applicant: Range Fuels, Inc.Inventors: David Tracy Gallaspy, John D.

Publication number: 20070046933Abstract: In a spectroscopic process a sample for producing a test spectral line or spectrum of at least one component contained in the sample is stimulated and the transmitted and/or emitted electromagnetic rays are used to create the test spectral line or spectrum. In order to improve such a spectroscopic process to such an extent that variations of certain parameters, which alter the shape and/or occurrence of a spectral line, are compensated, a comparison spectral line or spectrum of a known comparison material is produced under substantially the same parameters as the sample. The comparison spectral line or spectrum is compared with an ideal comparison spectral line or spectrum in order to calculate a transfer function, and the transfer function is applied to the test spectral line or spectrum in order to calculate a corrected test spectral line or spectrum.Type: ApplicationFiled: October 24, 2006Publication date: March 1, 2007Inventors: Yongdong Wang, Bernhard Radziuk, David Tracy

Patent number: 6658414Abstract: A method and system for creating, using, and updating individual user voice portals in a multi-user environment is disclosed. Each user selects data sources, keywords and time intervals for searching the data sources, and grammar for accessing search results. Based on this information, an individual voice portal is created for the user. The requested information is extracted from the specified data sources and cached or stored in a database to increase extraction speed. The user accesses the individual voice portal using a unique identifier assigned to the user and the selected grammar. Because each user has a unique voice portal, the search space for software that interprets the grammar is decreased. As a result, the likelihood of misinterpretation and the time for extracting the requested information are decreased.Type: GrantFiled: March 6, 2001Date of Patent: December 2, 2003Assignee: Topic Radio, Inc.Inventors: Edward Lee Bryan, David Tracy Bennett, Raymond Leo Idaszak, Suresh Balu

Patent number: 6033880Abstract: Apparatus and method for performing a nucleic acid amplification reaction and preferably a polymerase chain reaction (PCR) in a reaction mixture in at least one capillary tube. Several different embodiments are disclosed. One embodiment cycles a sample through a capillary tube loop passing through two thermostatted fluid baths. Another embodiment has the capillary tube routed alternatingly between two heat exchangers to that the sample makes only one pass through the tube. Other embodiments maintain the heat exchangers stationary and translate the samples between them. Still further embodiments maintain the samples stationary and either automatically translate or rotate the heat exchangers past the samples contained within the capillary tubes to perform the thermal cycles necessary for the amplification reaction.Type: GrantFiled: February 23, 1998Date of Patent: March 7, 2000Assignee: The Perkin-Elmer CorporationInventors: Lawrence A.
