20100011653 | STEERABLE FISHING LURE - A fishing lure that includes an adjustable head member statically coupleable in a first and second position, about an axis of rotation, to a body member. The body member has a vertical centerline plane. The adjustable head comprises a steering bill member projecting therefrom in a first direction. When the adjustable head member is in the first position, the first direction of the steering bill member is directed away from a first side of the centerline plane to steer the fishing lure, when moved through water, in a first steering direction. When the adjustable head member is in the second position, the first direction is directed away from a second side of the vertical centerline plane opposite the first side of the vertical centerline plane to steer the fishing lure, when moved through water, in a second steering direction. | 01-21-2010 |

20090167758 | Fast Triangle Reordering for Vertex Locality and Reduced Overdraw - Presented are systems and methods that change the order in which triangles are rendered, to improve post-transform vertex cache efficiency and reduce view-independent overdraw. The resulting triangle orders are orders magnitude faster to compute compared to previous methods. The improvements in processing speed allow such methods to be performed on a model after it is loaded (i.e., when more information on the host hardware is available). Also, such methods can be executed interactively, allowing for re-optimization in case of changes to geometry or topology, which happen often in CAD/CAM applications. | 07-02-2009 |
20100231588 | METHOD AND APPARATUS FOR RENDERING INSTANCE GEOMETRY - A method and apparatus for rendering instance geometry whereby all culling, level of detail (LOD) and scene management is performed directly on a GPU. | 09-16-2010 |

20100091018 | Rendering Detailed Animated Three Dimensional Characters with Coarse Mesh Instancing and Determining Tesselation Levels for Varying Character Crowd Density - A method carried out by graphics processing circuitry includes generating animated coarse mesh vertex information based on instanced coarse mesh data; and tessellating instanced coarse mesh data based on the animated coarse mesh vertex information to produce instances of a three dimensional object for display. A graphics processing circuitry includes programmable shader logic operative to execute programmable instructions that when executed cause the programmable shader logic to generate animated coarse mesh vertex information based on instanced coarse mesh data; and tessellate instanced coarse mesh data based on the animated coarse mesh vertex information to produce instances of a three dimensional object for display. Another method carried out by graphics processing circuitry includes determining density of a plurality of three dimensional objects in a current view on a display; setting a tessellation level based on said density; and tessellating said plurality of three dimensional objects. | 04-15-2010 |
20100141666 | Method and Apparatus for Spatial Binning on a GPU and Global Path Planning to Avoid Spatially Binned Objects - A method and apparatus for sorting data into spatial bins or buckets using a graphics processing unit (GPU). The method takes unsorted point data as input and scatters the points, in sorted order, into a set of bins. This key operation enables construction of a spatial data structure that is useful for applications such as particle simulation or collision detection. The disclosed method achieves better performance scaling than previous methods by exploiting geometry shaders to progressively trim the size of a working set. The method also leverages predicated rendering functionality to allow early termination without CPU/GPU synchronization. Furthermore, unlike previous techniques, the method can guarantee sorted output without requiring sorted input. This allows the method to be used to implement a form of bucket sort using the GPU. | 06-10-2010 |

20130220842 | Badge Holder With Ejector - A badge holder for holding a badge includes a front piece and a back piece opposite the front piece. The back piece is coupled to the front piece to provide a holding slot for the badge. A first ejector has a proximal end and a distal end. The proximal end is rotatably coupled to at least one of the front piece and the back piece. The first ejector is configured to rotate such that the distal end forces at least a portion of the badge out of the holding slot. | 08-29-2013 |
