Patent number: 8275428Abstract: Disclosed herein is a topologically protected ?/8-gate which becomes universal when combined with the gates available through quasi-particle braiding and planar quasi-particle interferometry. A twisted interferometer, and a planar ?/8-gate in CTS, implemented with the help of the twisted interferometer, are disclosed. Embodiments are described in the context of state X (CTS) supported by an ISH, although the concept of a twisted-interferometer is more general and has relevance to all anionic, i.e. quasiparticle systems.Type: GrantFiled: March 31, 2011Date of Patent: September 25, 2012Assignee: Microsoft CorporationInventors: Parsa Bonderson, Michael Freedman, Chetan Nayak, Kevin Walker, Lukasz Fidkowski

Patent number: 8269779Abstract: Computer-implemented methods and computer program products for automatically transferring expressions between rigs with consistent joint structure, and for automatically transferring skin weights between different skin meshes based on joint positioning. A method is provided for transferring an expression between a plurality of source rigs and a target rig, where each rig characterizes an animated character, and each rig, in turn, is characterized by a set of joints and a skin mesh having a plurality of vertices, with each vertex characterized by a matrix of weights relating a response of the vertex to movement of associated joints. A set of offsets is calculated of joint positions of a goal expression of each source rig relative to a neutral expression of the source rig. A scaling transformation is then applied to the set of offsets to produce a scaled set of offsets, which are added, in turn, to a neutral expression of the target rig.Type: GrantFiled: August 22, 2011Date of Patent: September 18, 2012Assignee: Image Metrics LimitedInventors: Michael Rogers, Kevin Walker, Steven Caulkin, Gareth Edwards

Publication number: 20110291342Abstract: Support engagement arrangements (100, 200, 1100, 1200, 2100, 3100, 3200) for utilisation in vices and presentation of components is a necessity, it is known to provide arrangements in which an array of engagement elements (2, 54, 64, 82, 92, 112, 902, 1401, 2003) are presented such that the elements can be displaced in order that ends define a reciprocal profile to a component (7, 57, 67, 87, 97, 117, 407, 1424, 2000). Retention of that reciprocal profile with prior arrangements is difficult. By providing the engagement elements supported upon a volume of particles (6, 56, 65, 86, 96, 116, 406, 806, 1402, 2006) which can act as a fluid medium relative displacement between the engaged elements can be achieved. Once displacement into a reciprocal profile is achieved the volume of particles is locked by actuator (4, 84, 94, 114, 404, 804, 904, 2007) pressure and therefore in support of a component resistance to vibration and other factors is significantly enhanced.Type: ApplicationFiled: September 23, 2009Publication date: December 1, 2011Inventors: Nabil Gindy, Yan Wang, Mark Daine, Kevin Walker

Patent number: 8061699Abstract: A clamping system for clamping aerofoils. The clamping system has pivotally mounted engagement members that engage the aerofoil mounted on a pivotally mounted arm either side of the pivotal mounting. The arm can pivot as required relative to the item, to accommodate differences in shape in the item, while providing a substantially equal clamping force by both engagement members.Type: GrantFiled: April 14, 2009Date of Patent: November 22, 2011Assignee: Rolls-Royce PLCInventors: Yan Wang, Nabil Gindy, Kevin Walker, Jamie Charles McGourlay, Michael James Berry

Publication number: 20110272537Abstract: Retention of position and clamping of components is ideally performed with an engagement arrangement which is reconfigurable. Magnetorheological (MR) fluids have been utilised for reconfigurable engagement arrangements but typically require powerful electromagnets to activate the MR fluid. By providing enclosed chambers with a constriction in the form of a passage between a reservoir portion of the chamber and an engagement portion of the chamber it is possible to utilise smaller permanent magnets acting upon a smaller volume of MR fluid in the passage. In such circumstances initial positioning of engagement elements is provided through forced displacement in the form of a plunger or pin and then retention of the engagement element position achieved through positioning a magnetic field across and about a passage to create an effective block retaining MR fluid volume and therefore presentation of the engagement element.Type: ApplicationFiled: April 2, 2009Publication date: November 10, 2011Inventors: Nabil Gindy, Amir Fahmi, Yan Wang, Venkata S.

Patent number: 7985005Abstract: A light module is removably coupleable to a light fixture and includes an LED lighting element mounted on a mounting base that is operatively coupled to a housing. The light module also includes one or more resilient members that operatively couple the mounting base to the housing and allow the mounting base and housing to resiliently move relative to each other. The resilient members compress when the light module is removably coupled to the light fixture to exert a generally axial force on the mounting base to drive the mounting base into resilient contact with a surface of the light fixture to provide a thermal coupling between the light module and the light fixture.Type: GrantFiled: March 6, 2007Date of Patent: July 26, 2011Assignee: Journée Lighting, Inc.Inventors: Clayton Alexander, Todd Metlen, Doug Botos, Jesse Melrose, Kevin Walker

Patent number: 7929745Abstract: A method and system for characterizing a knee joint in terms of its skeletal morphology. A plurality of loci associated with a model of skeletal structure of a knee joint are fitted and used to parameterize positions of the plurality of loci in a given subject and, thereby, to derive parameters of a deformable statistical template. The skeletal morphology is then characterized on the basis of the derived parameters of the deformable statistical template.Type: GrantFiled: April 16, 2010Date of Patent: April 19, 2011Assignee: Optasia Medical LimitedInventors: Kevin Walker, Jane Haslam, Anthony Holmes

Patent number: 7830384Abstract: A method and system for driving a graphical object based on a performance of an actor in a video stream. A plurality of key frames are selected in a calibration video stream, allowing animation control values to be defined, in accordance with artistic intent, for each of a set of control variables, corresponding to each of the key frames. Features of the actor in the calibration video stream are parameterized so as to obtain a vector of values of parameters for each frame of the calibration video stream, and, then, an array of distance vectors is derived, characterizing a distance between each pair of vectors of values of parameters among the video stream frames. The space of distance vectors is mapped into the set of control variables according to a mapping operation which is then applied to distance vectors derived from an actual performance video stream to obtain a time sequence of animation control values.Type: GrantFiled: April 19, 2006Date of Patent: November 9, 2010Assignee: Image Metrics LimitedInventors: Gareth Edwards, Kevin Walker
