Publication number: 20100332313Abstract: The claimed subject matter provides a system and/or a method that facilitates user selectable advertising networks. Advertising content can be formed into cohesive subsets of advertising. These subsets can be related to criteria to facilitate selection between available subsets of advertising content. A selection component can facilitate selection of the available subsets of advertising content based on these criteria. The criteria can be related to user preferences. Further the criteria can relate to explicit user preferences such as opt-in or opt-out indicia. The user can be presented with more relevant advertising content where user selection of advertising networks occurs.Type: ApplicationFiled: June 25, 2009Publication date: December 30, 2010Applicant: MICROSOFT CORPORATIONInventors: John M.

Publication number: 20100312782Abstract: A query may be applied against search engines that respectively return a set of search results relating to various items discovered in the searched data sets. However, presenting numerous and varied search results may be difficult on mobile devices with small displays and limited computational resources. Instead, search results may be associated with search domains representing various information types (e.g., contacts, public figures, places, projects, movies, music, and books) and presented by grouping search results with associated query domains, e.g., in a tabbed user interface. The query may be received through an input device associated with a particular input domain, and may be transitioned to the query domain of a particular search engine (e.g., by recognizing phonemes of a voice query using an acoustic model; matching phonemes with query terms according to a pronunciation model; and generating a recognition result according to a vocabulary of an n-gram language model.Type: ApplicationFiled: June 5, 2009Publication date: December 9, 2010Applicant: Microsoft CorporationInventors: Xiao Li, Patrick Nguyen, Geoffrey Zweig, Alejandro Acero

Publication number: 20090241960Abstract: A breathing system allows a single valve and corresponding control system to utilize either high or low pressure gas input and control the delivery of gas to a patient in a manner independent of the gas pressure level. Some such systems include a blower that provides gas with low pressure, a high pressure inlet port, a force balance valve or similar that will regulate the high pressure to work in the low pressure system, and a proportional valve assembly with a unitary control system that will allow for efficient ventilation operations regardless of gas source. Some such systems are capable of seamless transition from low to high pressure and from high to low pressure gas sources, as well as independent operation while either source serves as an input.Type: ApplicationFiled: April 1, 2008Publication date: October 1, 2009Applicant: eVent Medical, Inc.Inventors: Stephen Tunnell, Patrick Nguyen, Kosuke Inoue

Patent number: 7565906Abstract: A pressure/flow control valve that includes a first valve member and a second valve member moveable relative to one another and cooperating with one another so as to define a valve opening having a size that varies with a relative position between these members. The first magnet is operatively coupled to the first valve member and a second magnet is operatively coupled to the second valve member and magnetically coupled to the first magnet. The first and second magnets are disposed such that a repulsive force between them increases asymptotically as the magnets move together, thereby providing a dampening force between the first and second valve members that allows these valve members to be moved rapidly from one position to the next in a highly controlled fashion.Type: GrantFiled: April 26, 2004Date of Patent: July 28, 2009Assignee: RIC Investments, Inc.Inventors: Mabini M Arcilla, Mehdi M Jafari, Patrick Nguyen

Patent number: 7324943Abstract: A media capture device has an audio input receptive of user speech relating to a media capture activity in close temporal relation to the media capture activity. A plurality of focused speech recognition lexica respectively relating to media capture activities are stored on the device, and a speech recognizer recognizes the user speech based on a selected one of the focused speech recognition lexica. A media tagger tags captured media with generated speech recognition text, and a media annotator annotates the captured media with a sample of the user speech that is suitable for input to a speech recognizer. Tagging and annotating are based on close temporal relation between receipt of the user speech and capture of the captured media. Annotations may be converted to tags during post processing, employed to edit a lexicon using letter-to-sound rules and spelled word input, or matched directly to speech to retrieve captured media.Type: GrantFiled: October 2, 2003Date of Patent: January 29, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Luca Rigazio, Robert Boman, Patrick Nguyen, Jean-Claude Junqua
