20090271390 | PRODUCT SUGGESTIONS AND BYPASSING IRRELEVANT QUERY RESULTS - A computer system, computer media, and computer-implemented method for generating product suggestions and providing product information are provided. The computer system includes a relevance engine, a product database, and a graphical user interface to respond to user queries and to provide product details associated with one or more products included in the user queries.

The graphical user interface displays product suggestions that refine the user queries without executing the query on the product database, where a subset of the product suggestions are linked to product details pages. User selection of any of the product suggestions within the subset directs the user to a product details page for a specific product and bypasses a listing of results having many products that match the refined user queries. | 10-29-2009 |

20140268278 | Optical Polarimeter - A polarimeter is proposed that utilizes additional Stokes parameter measurements to determine both an average Stokes vector, as well as any rotation of the state of polarization around the Stokes vector. The optical polarimeter is configured to measure the state of polarization (SOP) under multiple, different conditions that yield both averaged Stokes vector and at least one other secondary (filtered) Stokes vector, the latter thus being determined from a subset of the conditions used to create the average Stokes vector. The secondary Stokes vector created from a filtered input will necessarily exhibit changes over time as a function of polarization transformations (based on filter-dependent changes), while the average Stokes vector will retain a constant value. Thus, a comparison of the average Stokes vector to the changing secondary Stokes vector allows for these polarization-dependent transformations to be recognized. | 09-18-2014 |
