Patent number: 7734721Abstract: The present invention is a system and method that monitors upgrade availability for computer information on a user's computer and allows the user to determine which of the available upgrades will be downloaded to the user's computer and installed. The upgrade availability for computer information on the user's computer is monitored in the background, without user-intervention when the user connects to a network, such as the Internet. If any such upgrades are available, a flag is set to notify the user of such upgrades. The user is notified of any available upgrades when computer information is accessed for which an upgrade is available, and given a choice of whether or not to download the available upgrade(s). The downloaded upgrade(s) may then be installed by an installation means. In this manner, the present invention allows for the user to download only those upgrades desired by the user.Type: GrantFiled: March 21, 2006Date of Patent: June 8, 2010Assignee: Apple Inc.Inventors: Gordon R. Meyer, Albert R. Howard, Jr., Wayne Loofbourrow

Publication number: 20080307013Abstract: Systems and methods for processing an index are described. To insure that the most updated index is available without having to update the index after every change (which can consume enormous resources), a specially marked postings list is generated for a changed item. During retrieval, the specially marked postings list supplements the existing content of an inverted index referencing the changed item. In this manner, the retrieval result for items containing the term under which the changed item was originally indexed is updated in accordance with the specially marked postings list to insure the most accurate retrieval result.Type: ApplicationFiled: June 8, 2007Publication date: December 11, 2008Inventors: Wayne Loofbourrow, John Martin Hoernkvist, Eric Richard Koebler, Yun-chih S.

Publication number: 20080306911Abstract: Systems and methods for processing an index are described. A postings list of items containing a particular term are ordered in a desired retrieval order, e.g., most recent first. The ordered items are inserted into an inverted index in the desired retrieval order, resulting in an ordered inverted index from which items may be efficiently retrieved in the desired retrieval order. During retrieval, items may first be retrieved from a live index, and the retrieved items from the live and ordered indexes may be merged. The retrieved items may also be filtered in accordance with the items' file grouping parameters.Type: ApplicationFiled: June 8, 2007Publication date: December 11, 2008Inventors: Wayne Loofbourrow, John Martin Hoernkvist, Eric Richard Koebler, Yan Arrouye

Patent number: 7369987Abstract: A multi-lingual indexing and search system is presented that performs tokenization and stemming in a manner which is independent of whether index entries and search terms appear as words in a dictionary. The system includes a tokenizer that separates a string of text into individual word tokens, and eliminates predetermined types of tokens from further processing. The system also includes a stemmer that reduces words to grammatical stems by removing known word-endings associated with the various languages to be supported. The stemmer removes known word endings from the word tokens without any effort to guarantee that the remaining stem is contained in a dictionary. In an embodiment, the stemmer only removes those word endings which are associated with nouns. The system further includes an indexer that stores the stems in an index.Type: GrantFiled: December 29, 2006Date of Patent: May 6, 2008Assignee: Apple Inc.Inventors: Wayne Loofbourrow, David Cásseres

Publication number: 20080033909Abstract: Systems and methods for improving indexing are described. In one exemplary method, a 2-level table is used to improve performance when searching an index. A first table contains a subset of more frequently occurring terms and a second and larger table contains terms that occur rarely, with the first table optimized for updating and the second table optimized for searching. The second table is searched only when a search of the first table is unsuccessful. Other methods are described and data processing systems and machine readable media are also described.Type: ApplicationFiled: August 4, 2006Publication date: February 7, 2008Inventors: John Martin Hornkvist, Eric Richard Koebler, Wayne Loofbourrow, Yun-chih S.

Publication number: 20070106500Abstract: A multi-lingual indexing and search system performs tokenization and stemming in a manner which is independent of whether index entries and search terms appear as words in a dictionary. During the tokenization phase of the process, a string of text is separated into individual word tokens, and predetermined types of tokens are eliminated from further processing. The stemming phase of the process reduces words to grammatical stems by removing known word-endings associated with the various languages to be supported. Known word endings are removed from the word tokens without any effort to guarantee that the remaining stem is contained in a dictionary. In a preferred implementation, the stemming process is only applied to nouns.Type: ApplicationFiled: December 29, 2006Publication date: May 10, 2007Inventors: Wayne Loofbourrow, David Casseres

Publication number: 20060253489Abstract: Techniques for detecting, managing, and presenting syndication XML (feeds) are disclosed. In one embodiment, a web browser automatically determines that a web site is publishing feeds and notifies the user, who can then access the feed easily. In another embodiment, a browser determines that a web page or feed is advertising relationship XML, and displays information about the people identified in the relationship XML. In yet another embodiment, a browser determines that a file contains a feed and enables the user to view it in a user-friendly way. In yet another embodiment, feed state information is stored in a repository that is accessible by applications that are used to view the feed. In yet another embodiment, if a feed's state changes, an application notifies the repository, and the state is updated. In yet another embodiment, a feed is parsed and stored in a structured way.Type: ApplicationFiled: March 27, 2006Publication date: November 9, 2006Inventors: Jessica Kahn, Jens Alfke, Sarah Wilkin, Albert Howard, Steven Jobs, Scott Forstall, Gregory Christie, Stephen Lemay, Donald Melton, Wayne Loofbourrow

Publication number: 20060253459Abstract: Techniques for presenting and managing syndication XML (feeds) are disclosed. In one embodiment, a user can modify how a feed is displayed, such as which content (and how much) is displayed, in what order, and how it is formatted. In another embodiment, a modification regarding how a feed is displayed is stored so that it can be used again at a later time. In yet another embodiment, a user can create a custom feed through aggregation and/or filtering of existing feeds. Aggregation includes, for example, merging the articles of multiple feeds to form a new feed. Filtering includes, for example, selecting a subset of articles of a feed based on whether they satisfy a search query. In yet another embodiment, a user can find articles by entering a search query into a search engine that searches feeds, which will identify one or more articles that satisfy the query.Type: ApplicationFiled: March 27, 2006Publication date: November 9, 2006Inventors: Jessica Kahn, Jens Alfke, Sarah Wilkin, Albert Howard, Scott Forstall, Stephen Lemay, Donald Melton, Wayne Loofbourrow

Publication number: 20060236261Abstract: In a scrollable user interface window including two or more panels, a single scroll bar scrolls all of the panels. Panels move in lock-step with one another at certain times, but not at other times, depending on whether the lock-step scrolling would cause blank areas to be displayed. If the user's scroll commands would result in a blank area of a panel being displayed, the scroll command is not performed; rather, the panel remains frozen in its current position, even while other panel(s) do scroll. Thus, the present invention ensures that useful content is displayed at all times in all panels, and no screen real estate is wasted due to scrolling operations.Type: ApplicationFiled: April 13, 2005Publication date: October 19, 2006Inventors: Scott Forstall, Gregory Christie, Kevin Tiene, Donald Melton, Stephen Lemay, Wayne Loofbourrow, Jessica Kahn, David Hyatt
