International Classification:

G02B006/28
G02B006/32
G02B006/34

US Classification:

385 24, 385 33, 385 37

Abstract:

A device for expanding the wavelength band of an optical component is disclosed. The device has a beam splitter for splitting a wavelength division multiplexed beam into two beams at a desired separation angle. An optical grating separates the two beams into spectral components for each beam. The spectral components are focused on a receiving surface. The separation angle between the two beams expands the wavelength band of the WDM signal.

G06F 17/30

US Classification:

707748, 707750

Abstract:

A search engine for databases, data streams, and other data sources allows user preferences as to the relative importance of search criteria to be used to rank the output of the search engine. A weighted preference generator generates weighted preference information including at least a plurality of weights corresponding to a plurality of search criteria. A weighted preference data search engine uses the weighted preference information to search a data source and to provide an ordered result list based upon the weighted preference information. A method for weighted preference data searching further includes allowing a user to re-rank the ordered result list and determine newly updated weighted preferences based on the re-ranking process. A plurality of weights signifying the relative importance of the search criteria may also be generated by the user inputting an ordered list. This ordered list may be a single alternative or a plurality of alternatives.

International Classification:

C07H 21/04

US Classification:

435209, 435105, 435 72, 536 232

Abstract:

The invention relates to recombinant expression of a variant form of a fungal C1 strain β-glucosidase. The invention also relates to the generation of fermentable sugars from biomass and the production of biofuels by fermentation of the sugars using genetically modified organisms expressing the β-glucosidase variant. The invention provides methods for producing a fermentable sugar, such as glucose, from cellobiose by contacting cellobiose with a recombinant β-glucosidase variant protein, such as a variant protein secreted by a recombinant host cell into culture medium. Methods of the invention may be used for conversion of a biomass substrate to a fermentable sugar, and ultimately to ethanol or other biofuel.

US Classification:

435 99, 435 41, 435162, 435163, 435209, 530350

Abstract:

The invention provides recombinant GH61 proteins obtained from , and nucleic acids that encode such proteins. The invention also provides protein fractions isolated from supernatant that have GH61 protein activity. These preparations can be used to increase yield of products from reactions in which a cellulose-containing substrate undergoes saccharification by one or more cellulase enzymes, such as endoglucanase, β-glucosidase, or cellobiohydrolase. Combinations of GH61 protein and cellulases can be used to break down cellulosic biomass into fermentable sugars in the production of ethanol.

Abstract:

A device for expanding an operable wavelength band of an optical component is disclosed. The device has an optical grating configured to receive a wavelength division multiplexed optical signal. The optical grating is configured to separate the optical signal into two wavelength bands separated by a prescribed wavelength difference. The device has a focusing lens system to focus the two wavelength bands onto a receiving surface. The two wavelength bands are separated on the receiving surface by the prescribed wavelength difference in order to expand the wavelength band of the WDM signal.
