Title: Markup language and object model for vector graphics
Inventor: BEDA JOSEPH S
IPC: G06F15/16
Filed: 2003-05-14
Abstract: An element object model and a vector graphics markup language for using that element object model in a manner that allows program code developers to consistently interface with a scene graph data structure to produce graphics. The vector graphics element object model generally corresponds to shape elements and other elements including image and video elements that correlate with a scene graph object model of the scene graph. Markup may be parsed into data including elements in an element tree that is translated into the objects of a scene graph data structure. Other markup may be translated directly into data and calls that create the scene graph objects. The markup language provides distinct ways to describe an element, including a simple string format or complex property syntax, which may be named, enabling reuse in other locations in the markup. <IMAGE>

Title: Optimization of Untreated Oil Shale Geometry to Control Subsidence
Inventor: ROBERT D KAMINSKY
Filed: 2008-12-04
Granted: 2013-03-03
Abstract: A method for developing hydrocarbons from a subsurface formation is provided. The subsurface formation may include oil shale. The method may include conductively heating portions of an organic-rich rock formation located in a development area, thereby pyrolyzing at least a portion of formation hydrocarbons located in a heated zone in the organic-rich rock formation into hydrocarbon fluids. The heat may be generated from one or more wellbores completed within the formation, such as by means of a resistive heating element. At least one unheated zone is preserved within the organic-rich rock formation. This leaves a portion of the development area substantially unpyrolyzed. The at least one unheated zone is sized or configured in order to substantially optimize that portion of the development area in which the organic-rich rock is pyrolyzed while controlling subsidence above the organic-rich rock formation.
