Patent number: 6834326Abstract: The present invention relates to transparent access to a redundant array of inexpensive devices. In particular, it provides a method and device for connecting redundant disk drives to a controller, preferably an intelligent switch, via a network. The disks are controlled by commands transported across the network. Commands may be SCSI, IDE/ATA or other commands. The network may comprise ethernet, fiber channel or other physical layer protocol. Commands can be encapsulated in IP packets and transmitted using either a reliable or unreliable transport protocol. Multicasting of packets from the controller to the multiple disk drives is part of the present invention.Type: GrantFiled: March 17, 2000Date of Patent: December 21, 2004Assignee: 3Com CorporationInventors: Peter S.

Patent number: 6834331Abstract: Sector and block layers for a database management system improve the integrity of data in a flash memory in view of possible data corruptions caused by power interruptions. The sector layer implements a reclaiming function for copying valid data from a source to a destination so that the source sector can be erased. A sector state register indicates whether a sector is in use, in a first reclaiming state, in a second reclaiming state or in a reclaimed state. A destination sector register for a reclaiming source points to a reclaiming destination. A limitation is placed on permissible reclaiming sources for a given reclaiming destination, so that, if a first sector is a permissible source for a second sector, then the second sector cannot be a permissible source for the first sector.Type: GrantFiled: October 24, 2000Date of Patent: December 21, 2004Assignee: Starfish Software, Inc.Inventor: Gwoho H. Liu

Patent number: 6810405Abstract: Methods for synchronizing PIM data between a wireless telephone and a synchronization server. A communication in interface is established between the telephone and the server, using a wireless network and the Internet. The telephone initiates the synchronization by placing a data call to the server and logging on to the server. A sync client within the telephone sends recent changes to its dataset to the server and requests an acknowledgement of these changes. In an acknowledgement message, the server specifies which changes were actually received. Based on this acknowledgment, the client continues resending changes until it receives confirmation that the server has received all of its changes. The server performs conflict and duplicate resolution between the changes received from the client and other changes of which the server is aware, and enters into its dataset those changes that survive the resolutions.Type: GrantFiled: October 4, 2000Date of Patent: October 26, 2004Assignee: Starfish Software, Inc.Inventors: Chris LaRue, Jeff Gray, Roy W. Feague

Patent number: 6751600Abstract: A system and method for automatic categorization of items into categories. Machine learning establishes or updates a data structure including term weights for text fields and distributions for numeric fields, based on a sample of pre-categorized items. An automatic categorization engine processes items by referencing the data structure on a field-by-field basis, determining a ranking score for each alternative category to which an item may be assigned. A category assignment may be based on ranking scores and may be flagged for a user to review. A user interface facilitates review and confirmation of automatic category assignments, either comprehensively, as flagged by the automatic categorization engine, or according to user determined criteria.Type: GrantFiled: May 30, 2000Date of Patent: June 15, 2004Assignee: Commerce One Operations, Inc.Inventor: Ben Wolin

Patent number: 6741759Abstract: The invention provides a method and device for interpolating between a first and second pixel in a video display system, where the first pixel has a first pixel value and a first coordinate on a first axis, and the second pixel has a second pixel value and a second coordinate on the first axis. The invention provides a first intermediate coordinate in between the first and second coordinates on the first axis, and determines a weight factor for the first intermediate coordinate. The weight factor is determined by either inputting the first intermediate coordinate into a first blending function if the first intermediate coordinate is within a first domain, or by inputting the first intermediate coordinate into a second blending function if the first intermediate coordinate is within a second domain. Once the weight factor is determined, a first interpolated value is calculated from a first product of the weight factor and a function of the first pixel value and the second pixel value.Type: GrantFiled: March 24, 2003Date of Patent: May 25, 2004Assignee: Macronix International Co., Ltd.Inventors: Michael M. Lee, Kun-Nan Cheng, Fu-Chi Wang

Patent number: 6726567Abstract: A game play system allows remote players to participate in a concurrent simulation of a live event as the live event is occurring. The system gathers input from sensors located at the live event, preprocesses this input, and transfers it to a computer system, which uses this input to create a concurrent simulation of the live event. A remote game player can then interact with the concurrent simulation by providing input to the concurrent simulation through a user interface. This system combines the excitement of a highly interactive video game with the drama and publicity surrounding a live event. The live event can thereby set the standard of performance for the concurrent simulation. Remote game players may additionally compete against each other to determine an overall global winner amongst the remote game players in the live event.Type: GrantFiled: December 17, 1999Date of Patent: April 27, 2004Inventor: Vinod Khosla
