20140331459 | Self-Retracting Lifeline Connecting System - Apparatus and associated methods may relate to a Self-Retracting Lifeline Connecting System (SRLCS) that securely attaches to a fall-protection safety harness, and further provides connections to a plurality of safety devices. In an illustrative example, the SRLCS may include a D-pad adapted for rear attachment to a back-pad of a safety harness. In some examples the D-pad may have webbing apertures through which two sections of webbing may be threaded in a criss-crossed manner. In some embodiments, the D-pad may provide an attachment for a first harness ring. In some exemplary embodiments, the D-pad may also provide a tunnel structure for routing a second harness ring therethrough. In an illustrative example, the tunnel may be located immediately adjacent the criss-cross location of the two sections of webbing, thereby permitting a carabiner to make use of the tunnel to capture the two sections of webbing. | 11-13-2014 |

20100104174 | Markup Language for Interactive Geographic Information System - Data-driven guarded evaluation of conditional-data associated with data objects is used to control activation and processing of the data objects in an interactive geographic information system. Methods of evaluating conditional-data to control activation of the data objects are disclosed herein. Data structures to specify conditional data are also disclosed herein. | 04-29-2010 |
20140028676 | WATER SURFACE GENERATION - Terrain data that represents earth features for a geographic area is received. The following meshes are generated based on the terrain data: (i) a water surface mesh including a first plurality of geometric primitives and (ii) a water bottom mesh including a second plurality of geometric primitives. Portions of the water bottom mesh appearing above the water surface mesh are identified. At least one of the water surface mesh and the water bottom mesh are corrected to cause the water surface mesh to appear above the water bottom mesh. | 01-30-2014 |
20140028706 | WATER SURFACE GENERATION - Systems and methods for approximating terrain data representing a water surface are disclosed. A computer-based geographical information system for approximating terrain data representing a water surface is provided. The system includes a mesh simplifier and a surface inversion corrector. The mesh simplifier simplifies initial water surface and water bottom meshes. The surface inversion corrector corrects simplified water surface and/or water bottom meshes to avoid having a water bottom surface incorrectly appear above a corresponding water surface in a display view. In one example, the mesh simplifier simplifies the initial water surface mesh while accounting for water/land boundaries. The mesh simplifier also simplifies the initial water bottom mesh while accounting for geographic features and/or water/land boundaries. A computer-implemented method for approximating terrain data representing a water surface is provided. In further embodiments, systems and methods for altering tile information received at a client device are provided. | 01-30-2014 |

20130132375 | Dynamic View-Based Data Layer in a Geographic Information System - Interactive geographic information systems (GIS) and techniques are disclosed that provide users with a greater degree of flexibility, utility, and information. A markup language is provided that facilitates communication between servers and clients of the interactive GIS, which enables a number of GIS features, such as network links (time-based and/or view-dependent dynamic data layers), ground overlays, screen overlays, placemarks, 3D models, and stylized GIS elements, such as geometry, icons, description balloons, polygons, and labels in the viewer by which the user sees the target area. Also, “virtual tours” of user-defined paths in the context of distributed geospatial visualization is enabled. Streaming and interactive visualization of filled polygon data are also enabled thereby allowing buildings and other such features to be provided in 3D. Also, techniques for enabling ambiguous search requests in a GIS are provided. | 05-23-2013 |

20130187939 | Texture Fading for Smooth Level of Detail Transitions in a Graphics Application - Systems and methods for providing smooth level of detail (“LOD”) transition for textures in a graphics applications are disclosed. The texture LOD of a first frame of imagery can be compared to a second texture LOD for a current frame. For areas where the second LOD is higher than the first LOD, an LOD fade from the first LOD to the second LOD can be performed to provide a smooth LOD transition. The LOD fade can be implemented by generating a blend between textures at the first LOD and the second LOD. In one aspect, the blend is generated based on an interpolant value calculated based on the difference between the first LOD and the second LOD. The interpolant value can be incremented in subsequent frames to achieve a desired fade rate for the transition. The fade rate can be variable such that the LOD transition time remains constant. | 07-25-2013 |
20130321399 | Level of Detail Transitions for Geometric Objects in a Graphics Application - Systems and methods for providing smooth level of detail transitions for geometric objects, such as geometric terrain tiles, are provided. In one embodiment, a parent geometric tile associated with a first level of detail can be partitioned into sub-tiles. The sub-tiles can be blended independently with child geometric tiles associated with a second level of detail. The blends can be adjusted as a function of camera distance over a transition range to provide a smooth level of detail transition. Various enhancements and modifications can be made to the level of detail transition, such as implementing a bias in the level of detail calculation, implementing an unpop algorithm over only a subset of the transition range, implementing a time based fade during a camera stop, and other enhancements. | 12-05-2013 |
20130325903 | System and Method for Storing and Retrieving Geospatial Data - Systems and methods for storing and retrieving geospatial data in a geographic information system are provided.

20150066805 | LOCATION-BASED ADAPTATION OF FINANCIAL MANAGEMENT SYSTEM - Location-based adaptation of financial management system. Crowdsourced feedback regarding financial management system content is tagged with location data such as an IP address and/or geographic location data. Location-specific counters track feedback received from different locations and may involve different languages, dialects, phrases or other manners of expression associated with different countries, states or regions thereof. When pre-determined criteria is satisfied, e.g., a threshold number of counts associated with a particular location, associated location-based feedback is analyzed and identified feedback patterns are used to selectively modify previously presented financial management system content and adapt the financial management system is adapted to different locations by presenting first modified content based at least in part upon a first identified pattern to users at a first location and second modified content based at least in part upon a second identified pattern to users at a different, second location. | 03-05-2015 |
