Publication number: 20240108332Abstract: A method of operating an articulatable surgical instrument. The method includes providing a rotary drive motion to a rotary drive member of a surgical end effector and converting the rotary drive motion to an upper axial motion and a lower axial motion at locations that are distal to the articulation joint. The method further includes applying the upper axial motion to an upper portion of a firing member and applying the lower axial motion to a lower portion of the firing member such that the upper axial motion and lower axial motion drives the firing member distally through the surgical end effector from a starting position to an ending position.Type: ApplicationFiled: December 12, 2023Publication date: April 4, 2024Inventors: Gregory J. Bakos, Darryl A. Parks, Benjamin D. Dickerson, Steven G. Hall, Robert J. Simms, Spencer J. Witte, Taylor W. Aronhalt, Paul Moubarak, William C. Ryle

Publication number: 20230036153Abstract: A process for scheduling engine inspection for a gas turbine engine includes computing an expected damage increment based on aircraft usage data of a single flight, computing a cumulative expected damage by summing the expected damage increment with a total set of historical expected damage increments since a previous maintenance, and determining an aggregate risk of failure based on the computed cumulative expected damage. A manual inspection is signaled when the aggregate risk of failure exceeds an acceptable risk threshold.Type: ApplicationFiled: September 2, 2021Publication date: February 2, 2023Inventors: William D. Owen, Benjamin D. Hall, Emily Carolyn Roto Coleman, Cami Santor, Eric D. Kachel, Alex J. Brown

Patent number: 9483605Abstract: A novel probabilistic method for analyzing high cycle fatigue (HCF) in a design of a gas turbine engine is disclosed. The method may comprise identifying a component of the gas turbine engine for high cycle fatigue analysis, inputting parametric data of the component over a predetermined parameter space into at least one computer processor, using the at least one computer processor to build a plurality of flexible models of the component based on the parametric data of the component over the predetermined parameter space, using the at least one computer processor to build a plurality of emulators of the component based on the plurality of flexible models, and using the at least one computer processor to predict a probability of HCF based at least in part on the parametric data of the component over the predetermined parameter space and the plurality of emulators.Type: GrantFiled: December 19, 2013Date of Patent: November 1, 2016Assignee: UNITED TECHNOLOGIES CORPORATIONInventors: Robert J.

Publication number: 20140007591Abstract: A disclosed airfoil health monitoring system and method obtains a signal comprising a waveform indicative of an airfoil path with a sensor. Features of the waveform are determined and compared waveform characteristics indicative of a vibrational mode. A vibrational mode of the airfoil may then be determined based on the comparison between the predetermined waveform characteristics and the obtained waveform indicative of the airfoil path.Type: ApplicationFiled: July 3, 2012Publication date: January 9, 2014Inventors: Alexander I. Khibnik, Benjamin D. Hall

Patent number: 6544757Abstract: The present invention relates to synthesis of HBSAg in yeast. Yeast expression vectors comprising a yeast promoter, ADH1, have been constructed. The region of the HBV genome coding for the S-protein, excluding a possible 163 amino acid presequence, has been transferred to the yeast expression vector. Using the described yeast vector, the successful synthesis of HBSAg by yeast has been achieved. The product is antigenic (reactive with anti-HBSAg), and a substantial portion is found associated with particles identical in electron microscopic appearance to those found in the serum of HBV-infected patients and in Alexander cells but having a smaller particle size diameter. The HBSAg synthesized by yeast has identical sedimentation behavior to purified, naturally occurring HBSAg particles purified from Alexander cells as measured by sucrose gradient sedimentation.Type: GrantFiled: June 21, 1988Date of Patent: April 8, 2003Assignee: The Regents of the University of CaliforniaInventors: William J. Rutter, Pablo D. T. Valenzuela, Benjamin D. Hall, Gustav Ammerer
