Patent number: 8027953Abstract: A system and methods for synchronizing datasets are provided that are especially suitable and efficient for a user who has three or more datasets that need to be occasionally synchronized, with no one dataset or synchronization system being guaranteed to participate in every synchronization. Synchronization status information, such as correspondences between data records of particular multiple datasets, is stored with more than one of the datasets. When two datasets that contain synchronization status information synchronize with each other, they not only synchronize user data and exchange status information involving each other, but they also synchronize and exchange status information involving “third-party” datasets that may not be participating in the synchronization.Type: GrantFiled: March 8, 2002Date of Patent: September 27, 2011Assignee: Intellisync CorporationInventors: Chris LaRue, Bryan Dube

Patent number: 7154621Abstract: An improved Internet delivery system for digitized photographs is described. The system embodies methodologies that speed the delivery of digitized images from photographic film scan centers to consumers across the Internet with high reliability. By delivering all the digital images to a more powerful centralized server infrastructure prior to the consumer's earliest opportunity to view them on-line, these images or pictures can be downloaded to a viewer of interest (e.g., user or family member) quickly enough to provide an appropriate Web response. Optimizations are also described that streamline the throughput with load balancing and provide virtually guaranteed uniform service with fail-over. In this manner, the system provides improved access, storage, and on-line availability of digital images.Type: GrantFiled: March 20, 2001Date of Patent: December 26, 2006Assignee: Lightsurf Technologies, Inc.Inventors: John Rodriguez, Brian Bodmer, Bryan Dube, Mark Tarantino, Jonah Kaj Fleming, Shekhar Kirani

Patent number: 6915312Abstract: A synchronization system providing multi-client synchronization is described. By storing the data that is actually being synchronized (i.e., storing the actual physical body of a memo, for instance) inside an extra database, “Grand Unification Database” (GUD), (or by specially-designated client data set) under control of a central or core synchronization engine, rather than transferring such data on a point-to-point basis, the system of the present invention provides a repository of information that is available at all times and does not require that any other synchronization client (e.g., PIM client or hand-held device) be connected. The GUD provides a super-set of the other client data sets. Therefore, if the user now includes an additional client, such as a server computer storing user information, the synchronization system has all the information necessary for synchronizing the new client, regardless of whether any of the other clients are currently available.Type: GrantFiled: August 13, 2001Date of Patent: July 5, 2005Assignee: Starfish Software, Inc.Inventors: Eric O. Bodnar, Chris LaRue, Bryan Dube, Shekhar Kirani, Sethuraman Suresh
