Patent number: 11708155Abstract: A multimode clutch assembly is positioned in a powertrain of a rotorcraft. The clutch assembly includes a freewheeling unit having a driving mode in which torque applied to the input race is transferred to the output race and an overrunning mode in which torque applied to the output race is not transferred to the input race. A bypass assembly has an engaged position that couples the input and output races of the freewheeling unit. An actuator assembly shifts the bypass assembly between engaged and disengaged positions. An engagement status sensor is configured to determine the engagement status of the bypass assembly. In the disengaged position, the overrunning mode of the freewheeling unit is enabled such that the clutch assembly is configured for unidirectional torque transfer. In the engaged position, the overrunning mode of the freewheeling unit is disabled such that the clutch assembly is configured for bidirectional torque transfer.Type: GrantFiled: November 1, 2021Date of Patent: July 25, 2023Assignee: Textron Innovations Inc.Inventors: Douglas Andrew Goodwin, David Andrew Prater, Eric Stephen Olson, David Bryan Roberts, Chia-Wei Su, Michael David Trantham, Charles Eric Covington

Publication number: 20200169567Abstract: A computer-implemented method, as well as a computer program product and apparatus, provide for authenticating a plurality of authorized users requesting access to a media object, wherein the media object includes a plurality of media sub-elements, each media sub-element delimiting specific content of the media object. For each of the plurality of sub-elements, a classification level associated with the media sub-element is identified. A security clearance is obtained for each of the plurality of authorized users. For each of the authorized users, output is provided that is formed from the media object with redaction of each sub-element associated with a classification level that prevents access using the security clearance of the authorized user.Type: ApplicationFiled: November 27, 2018Publication date: May 28, 2020Inventors: Charles Christian Queen, Fred Allison Bower, III, David Bryan Roberts

Patent number: 7886285Abstract: The present invention provides a method, data processing system and computer program product in which a plurality of software executable libraries (sub-libraries) are combined into a single software executable library. The single library comprises a plurality of register functions, each associated with a particular sub-library and each sub-library comprises one or more functions. When the library receives a request to register from a library manager it calls each of the register functions, each of which register the one or more functions of its associated sub-library with the library manager. Advantageously the library manager can subsequently interface with each sub-library as if the sub-library was a standalone library. Further a register function can be used for a library whether the library is sub-library or a standalone library, thereby reducing the effort to switch from one to the other.Type: GrantFiled: March 14, 2006Date of Patent: February 8, 2011Assignee: International Business Machines CorporationInventors: Albert Andre Asselin, Fred Allison Bower, III, David Bryan Roberts

Patent number: 7673183Abstract: A method and system for ordering and aggregating log streams. Log streams for events from different sources are received. If different sources have different recording cycles, or time epochs, that lead to different temporal granularities, then all of the log streams are combined into a single time epoch that is equal to the longest time epoch. Log streams from sources having shorter time epochs continue to retain information about their original time epochs, in order to retain information about the order of the events in those log streams. The log streams are re-ordered, both before and after being integrated into the aggregate log, by acquiring additional data from the different sources, thus permitting the likely cause/effect relationship between events.Type: GrantFiled: March 14, 2008Date of Patent: March 2, 2010Assignee: International Business Machines CorporationInventors: Fred Allison Bower, III, Rodney Hugh Brown, Tushar Dasharath Fadale, Thomas James Fox, Richard Edwin Harper, David Bryan Roberts, Ketan K.
