  • Publication number: 20130064509
    Abstract: 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.

  • Publication number: 20100270505
    Abstract: 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).

  • Publication number: 20070211467
    Abstract: A method of increasing the spatial uniformity of the detected intensity of a beam of light from a laser in a system including the laser and a light detector. In one embodiment the method includes the steps of generating a beam of light with the laser; and moving the beam of light and the light detector relative to each other, such that the detector averages the spatial intensity of the beam of light over time. In another embodiment the invention relates to a system for increasing the detected spatial uniformity of the intensity of a beam of light.

  • Publication number: 20070109542
    Abstract: An optical analysis unit especially suitable for performing grating coupled surface plasmon resonance (SPR) imaging features a pivoting light source capable of scanning through a range of angles of incident light projected onto a stationary target sensor, such as an SPR sensor. The reflected image from the illuminated sensor is detected, e.g., by a CCD camera and the image and angular scan data are processed, for example by a fitting algorithm, to provide real time analysis of reactions taking place on the surface of the sensor.

  • Publication number: 20070046933
    Abstract: 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.

  • Patent number: 7133869
    Abstract: Methods and systems for defining and distributing information alerts include presenting a user with a series of templates that allows the user to define security events, information alerts to be triggered by the events, and intended recipients for the alerts. Intended recipients for the alerts are presented with templates that allow the individuals to input contact and schedule information for receiving the information alerts. A knowledge switch uses the event definitions and the contact and schedule information to detect events and distribute the information alerts to the intended recipients when an event occurs. The information alerts include directives that instruct intended recipients regarding action to be taken in response to a security event.

  • Patent number: 6658414
    Abstract: 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.

  • Patent number: 6033880
    Abstract: 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.
