  • Patent number: 7010527
    Abstract: A method and system for determining relevance rankings for pages identified in a search query is provided. In response to the search query, an information retrieval system identifies candidate pages/documents from a network that potentially match the search query. A relevance ranking system determines a relevance value for each of candidate pages so that the most relevant pages are displayed to a user. The relevance value is based on a combination of content-based relevance values of the pages and link values determined from a link structure of the pages. A link value is a function of a probability that a user will follow the link as compared to following all other links. With the present invention, improved relevance rankings are obtained for a candidate set of pages.

  • Patent number: 6947920
    Abstract: A method and system for optimizing response time for data query rankings and retrieval is provided. In response to a received search query that contains one or more terms, an information retrieval system identifies a candidate set of documents that match any of the terms. Terms are assigned a term weight making them more or less relevant in relation to other terms. A ranking logic defines score bins from a total score range based on possible matched term weights. A relationship is established that classifies a document into a score bin based on a sum of term weights from matched terms. Documents that match more term weights have higher total relevance scores than documents that match less term weights. The most relevant documents are retrievable without having to retrieve the entire set of candidate documents and without having to compute total relevance scores for all the candidate documents.

  • Patent number: 6860501
    Abstract: A weight distributing hitch assembly includes a shank, hitch head, spring bar and lift assembly. The lift assembly is preferably removably mountable to the frame members of a trailer frame while the spring bar extends below the frame members relative to the ground. The lift assembly mounts a hanger assembly which engages a cantilevered segment of the spring bar to drive the spring bar from a free state to a loaded state to distribute the hitch load to a towing vehicle as well as to the trailer. A lever assembly mounts the hanger assembly to the lift assembly and supplies mechanical advantage to assist a user during tensioning of the spring bar. By moving the lever assembly, the cam rotates about a pivot. As the hanger assembly is engaged with the cam, the hanger assembly is driven from a disengaged position to an engaged position which moves the spring bar from its free state to its loaded state with a minimum of user effort.

  • Patent number: 6722686
    Abstract: A device for closing the socket of a trailer hitch, generally called a coupler lock, generally comprises a locking bar and a base having a plug member, a locking bar-receiving aperture, and an integral locking means for lockingly engaging the locking bar within aperture. When the coupler lock is attached to a trailer coupler, the trailer hitch socket is not accessible without removing the coupler lock with the appropriate key. Thus, theft of an unattended trailer is deterred due to the difficulty in attempting to remove the locking device. Providing a coupler lock having an integral locking mechanism better deters the tampering with or removal of the locking mechanism to remove the coupler lock from the trailer hitch as is possible in the art.
