Title: Technical analysis formation recognition using pivot points
Inventor: SATCHWELL CHRISTOPHER J
IPC: G06Q40/06
Filed: 2002-09-17
Abstract: A method of formation recognition in technical analysis relies on the use of pivot points. A formation of interest is defined in terms of extreme points. The extreme points can be characterized in relation to one another as a series of local or global extrema in corresponding intervals. The method numbers the pivot points in reverse chronological order and attempts to match pivot points with the extreme points of the formation of interest. The first pivot point is assigned to the first extreme point of the formation. A second pivot point is selected from the interval defined by the first pivot point and the highest numbered pivot point that is a high or a low, as required by the formation. Subsequent pivot points are selected from intervals determined based on the formation and previously determined intervals. A formation is recognized if corresponding pivot points are identified for all extreme points in the formation.

Title: Method and system for modeling geological structures using an unstructured four-dimensional mesh
Inventor: WARD STEVEN B
IPC: G06T17/05
Filed: 2001-06-29
Abstract: A method for solving space-time problems involving three-dimensional space wherein an unstructured four-dimensional finite element model is generated and solved to produce a four-dimensional solution. The four-dimensional mesh is generated from a three-dimensional mesh by extruding each of the simplices of the three-dimensional mesh in a time dimension. The four-dimensional prisms formed by extrusion of the three-dimensional simplices are divided into a plurality of four-dimensional simplices which form a four-dimensional finite element model. The elements of the four-dimensional model can be selectively refined to obtain a finer mesh in areas of greater interest, and a coarser mesh in areas which are of less interest. The mesh can be refined in the spatial dimensions and also in the temporal dimension.

Title: Reverse phase control power switching circuit with overload protection
Inventor: HUA JENKIN P
IPC: H02M5/293
Filed: 2003-04-15
Abstract: In one embodiment of the invention, a reverse phase control power switching circuit for controlling the flow of current through a load from an AC source comprises a sensing bridge in series with the load and the AC source. The conductive state of the sensing bridge is responsive to a pulse generator and a zero creasing detection and overload protection means. Phase control means coupled to the pulse generator determines turn off of the sensing bridge is reset by the zero crossing detection and overload protection means. Responsive to a load current condition exceeding a maximum current caused by an overload or a short, the zero crossing detection and overloading protection network terminates conduction of current through the sensing bridge. The sensing bridge starts conducting current to the load at the beginning of the AC cycle and continues to conduct to a desired AC voltage phase angle or earlier if an excessive current condition caused by an overload condition or a short occurs.
