Patent number: 8503834Abstract: The present invention provides an apparatus for distributed pressure sensing. The apparatus comprises a series of Bragg gratings, a light guide incorporating the series of Bragg gratings and a plurality of moveable wall portions. The moveable wall portions are coupled to respective Bragg gratings so that the movement of one of the moveable wall portion causes a force on the respective Bragg grating resulting in a change in strain of the respective Bragg grating. The apparatus also comprises at least one rigid member that is attached at attachment regions between which a sensing region of at least one Bragg grating is defined. The rigid member is arranged so that a strain in the sensing region is not directly influenced by a change in strain of the light guide outside the sensing region.Type: GrantFiled: March 9, 2006Date of Patent: August 6, 2013Assignee: Commonwealth Scientific and Industrial Research OrganisationInventors: John William Arkwright, Simon Nicholas Doe, Vinay Kumar Tyagi, Edward William Preston

Patent number: 8479050Abstract: A method, apparatus, and computer instructions in a processor for selectively performing operations on data. An operation to be performed on data is identified to form an identified operation. A determination is made as to whether metadata identifying a state of the data is associated with the data. A determination is made as to whether the identified operation can be performed on the data based on the state of the data, in response to the metadata being associated with the data. The operation is performed on the data if the state of the data allows for the operation to be performed. The processor selectively performs the operations based on the state of the data.Type: GrantFiled: January 11, 2011Date of Patent: July 2, 2013Assignee: International Business Machines CorporationInventors: William Preston Alexander, III, Frank Eliot Levine, Robert John Urquhart

Publication number: 20120311543Abstract: A method and apparatus for identifying a minimum call tree data structure from a plurality of call tree data structures are provided. With the apparatus and method, call tree data structures are generated for two or more executions of a build of a computer program. The apparatus and method perform a “tree-minimization” operation in which the two or more call trees generated during runs of the computer program are walked and only those nodes that are present in each of the tree data structures are maintained in a minimized tree data structure. In addition, the minimum values for these common nodes are maintained in the minimized tree data structure. In this way, asynchronous events are removed from the minimum tree data structure and analysis may focus on those areas of the computer program that are consistent between runs of the computer program.Type: ApplicationFiled: August 14, 2012Publication date: December 6, 2012Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: William Preston Alexander, III, Robert Tod Dimpsey, Frank Eliot Levine, Robert John Urquhart

Patent number: 8136988Abstract: A temperature sensor is described that includes a base, a first set of posts attached to the base having a first coefficient of thermal expansion, a second set of posts attached to the base and having a second coefficient of thermal expansion, and two substantially parallel conductive plates forming a capacitor. The first of the conductive plates is fixed to the first set of posts and the second of the conductive plates is fixed to the second set of posts. Temperature changes cause the first set of posts and the second set of posts to elongate at different rates, thereby changing a distance between the conductive plates and therefore the resulting capacitance. A system and method are also described for determining resonant frequency associated with the sensor which correlates to the temperature at the sensor when multiple sensors are networked across a system.Type: GrantFiled: January 15, 2009Date of Patent: March 20, 2012Assignee: The Boeing CompanyInventors: William Preston Geren, Brian Kenneth Kormanyos, Kathryn A.

Publication number: 20110277246Abstract: An orthopedic device for improving posture while sitting, having a foundation member including a front portion for upper legs and a bowl portion for lower pelvic area. The bowl portion has a central portion and an upwardly inclined lateral portion. The lateral portion and the front portion collectively surround the central portion. The central portion has regions of varying flexibility and the lateral portion has regions of varying flexibility. The bowl portion applies an upwardly and inwardly compressive force when the lower pelvic area is disposed in the bowl portion, and rotates on a supporting surface between a first position when the lower pelvic area is not disposed in the bowl portion, and a second position, rotationally forward of the first position, when the lower pelvic area is disposed in the bowl portion, to thereby cause a forward rotational tilting of the lower pelvic area into a forward lordotic position after the lower pelvic area is placed in the bowl portion.Type: ApplicationFiled: January 22, 2010Publication date: November 17, 2011Applicant: BACKJOY ORTHOTICS, LLCInventor: William Preston Willingham

Patent number: 8047004Abstract: An engine exhaust nozzle comprises a plurality of CMC staves attached to one or more support rings arranged axially. The support rings provide a circumferential load path between the staves and for attaching the exhaust nozzle to the metallic engine components. The staves are fixed to the support rings with a spacing intended to accommodate for relative movement due to the difference in CTE for the CMC and metallic components and due to thermal gradients through the wall thickness. The resulting apparatus is lightweight, relieves the nozzle of thermal stresses, and is easier to manufacture and repair.Type: GrantFiled: February 12, 2008Date of Patent: November 1, 2011Assignee: The Boeing CompanyInventors: John Joseph Brown, William Preston Keith

Patent number: 8031988Abstract: The present invention provides an apparatus for pressure sensing. The apparatus comprises a light guide, a Bragg grating incorporated into the light guide and a moveable wall portion. The moveable wall portion has opposite first and second sides and is being positioned so that a change in pressure at one of the sides relative to a pressure at the other side will move the moveable wall portion. The moveable wall portion is coupled to the Bragg grating so that the movement of the moveable wall portion causes a force on a side of the Bragg grating. The force has a component that is transversal to the Bragg grating and effects a change in strain of the Bragg grating and thereby a change in an optical period of the Bragg grating.Type: GrantFiled: March 9, 2006Date of Patent: October 4, 2011Assignee: Commonwealth Scientific and Industrial Research OrganisationInventors: John William Arkwright, Simon Nicholas Doe, Vinay Kumar Tyagi, Edward William Preston
