Patent number: 7613794Abstract: Technology is disclosed for identifying dynamic groups that correspond to a user of a system. A system partitions a set of dynamic groups into multiple test sets of dynamic groups. The system selects a test set and determines whether the user corresponds to the test set. In one implementation, the system combines the filters for the dynamic groups in each test set into a single test set filter. The test set filter is satisfied if the filter of any dynamic group in the test set is satisfied. This allows the system to perform a single comparison between the resulting test set filter and the user's profile to determine whether the user is a member of any dynamic group in the test set. If the user is not a member of any dynamic group in the test set, the system eliminates all of the test set's dynamic groups from consideration, based on the single comparison. Otherwise, the dynamic groups in the test set remain in a list of groups that may include the user. This process is repeated for each test set.Type: GrantFiled: March 12, 2007Date of Patent: November 3, 2009Assignee: Oracle International CorporationInventors: Shawn P. Delaney, Robert Summers

Publication number: 20070027986Abstract: The present invention provides cache flushing of selected data while leaving remaining cached data intact. Data can be flushed from caches distributed across various components of a network-based computer system. These caches can contain various types of data. In one embodiment, the caches exist in an Access System and contain user identity profile information. In another embodiment, the caches exist in an Access Management System and contain authentication, authorization, or auditing rules. A system in accordance with the invention detects a change to data residing on a server and transmits a synchronization record to a component of the system. The synchronization record identifies the changed data. The system flushes the changed data identified by the synchronization record from caches of the component.Type: ApplicationFiled: October 3, 2006Publication date: February 1, 2007Applicant: Oracle International CorporationInventors: Vrinda Joshi, Praveen Swadi, Robert Summers

Patent number: 7006333Abstract: The invention provides a disk drive suspension. The suspension has a load beam and a flexure having a frame and a tongue portion having a base and a tongue. The flexure mounts one or more microactuators in opposed or offset relation for shifting the base of the flexure tongue portion relative to the flexure frame and thus positionally adjusting the tongue and the slider fixed to the tongue with respect to the disk that is in operating proximity to the slider.Type: GrantFiled: June 27, 2002Date of Patent: February 28, 2006Assignee: Magnecomp CorporationInventor: Robert Summers

Publication number: 20060016935Abstract: A spacecraft architecture and accompanying standard allows for the creation of a spacecraft using an assortment of modules that comply with the standard. The standard preferably includes both mechanical and electrical compatibility criteria. To assure physical/mechanical compatibility, the structure of each module is constrained to be compatible with any other compatible module. To minimize the interference among modules, the extent of each module in select dimensions is also constrained. To assure functional compatibility, a common communication format is used to interface with each module, and each public-function module is configured to respond to requests for function capabilities that it can provide to other functions. Each module is preferably designed to provide structural support to the assemblage of modules, and an anchor module is provided or defined for supporting the entire assemblage and coupling the assemblage to other structures, such as a launch vehicle.Type: ApplicationFiled: June 14, 2005Publication date: January 26, 2006Inventors: Luis Jordan, Thomas Vanek, Scott McDermott, Jonathon Miller, Simon Weiss, Robert Summers

Patent number: 6905336Abstract: A dental implant impression confirmation system utilizes one or more telescoping crossbrace members. Each crossbrace links one coping to an adjacent coping. The ends of the telescoping crossbraces include tubular eyelets or collars which each attach to a coping by snap-fit. The crossbraces further include articulated joints at each end to accommodate attachment between copings which are not parallel. The crossbrace members are preferably composed of a semi-rigid material such as plastic which permits resilience of the confirmation system to allow for the withdrawal of the copings from the implants while supplying sufficient rigidity to enhance the accuracy of the impression.Type: GrantFiled: July 23, 2002Date of Patent: June 14, 2005Inventor: Robert Summers
