Patent number: 8521713Abstract: Expert domains for a query category represent domains from which a high percentage of search results for queries associated with the query category are retrieved. The expert domains are identified by establishing a base statistical model that indicates frequencies of appearance for domains in search results retrieved for queries corresponding to multiple categories. In addition, frequencies of domain appearance are determined for search results retrieved for queries associated with a category. Domains that appear more frequently in the search results corresponding to the category are identified as expert domains for the category. A user may be allowed to customize expert domains related to one or more categories by adding or removing expert domains for the category.Type: GrantFiled: July 11, 2011Date of Patent: August 27, 2013Assignee: Microsoft CorporationInventors: Abdur R. Chowdhury, Gregory S. Pass, Gerald Frederick Campbell

Patent number: 8470452Abstract: A wear resistant ceramic coated aluminum alloy article. The article is made by a method including the steps of: a) immersing the article in an aqueous electrolyte containing from about 1.5 to about 2.5 grams per liter of alkali metal hydroxide and from about 6.5 to about 9.5 grams per liter of alkali metal silicate. No more than 1 g per liter of alkali metal pyrophosphate is present and no more than about 0.05 percent of hydrogen peroxide is present, and b) applying an alternating current through the electrolyte using the article as one electrode where a second electrode includes at least one of an electrically conductive container or an immersed separate electrode, where applied EMF is selected to provide a current density of from about 15 to about 25 A/dm2, for a sufficient time to obtain a wear resistant ceramic coating having a thickness of from about 125 to about 150 ?m.Type: GrantFiled: June 21, 2011Date of Patent: June 25, 2013Assignee: Calvary Design Team, Inc.Inventors: Mark R.

Patent number: 7418915Abstract: An entrapment tunnel watercraft vessel having three hulls consists of a main hull and two amas arranged outboard of the main hull with the keels of the three hulls being parallel. The main hull is a narrow, vee hull with variable, rearwardly decreasing deadrise. The amas have very fine bows and narrow, asymmetric deep-V hulls, with nearly vertical slab outboard sides above their keels and variable reverse deadrise on their inboard sides with the reverse deadrise angles decreasing from bow to stem. The tunnels on each side of the main hull are formed by three distinct surfaces, the sides of the main hull above its chine, the reverse deadrise inboard sides of each ama upward from their keels and a ceiling surface transversely spanning the aforementioned sides and having rearwardly increasing deadrise and rearwardly decreasing width. The tunnel ceilings slopes down from the bow to a section aft of midship where the ceiling height above the keel remains essentially constant.Type: GrantFiled: March 15, 2007Date of Patent: September 2, 2008Assignee: Navatek, Ltd.Inventor: Lorne Frederick Campbell
