Filed: 2005-03-11
Abstract: ABSTRACT Methods and apparatus to perform wavefront analysis, including phase and amplitude information, and 3D measurements in optical systems, and in particular those based on analyzing the output of an intermediate plane, such as an image plane, of an optical system. Measurement of surface topography in the presence of thin film coatings, or of the individual layers of a multilayered structure is described.. Multi-wavelength analysis in combination with phase and amplitude mapping is utilized. Methods of improving phase and surface topography measurements by wavefront propagation and refocusing, using virtual wavefront propagation based on solutions of Maxwell's equations are described. Reduction of coherence noise in optical imaging systems is achieved by such phase manipulation methods, or by methods utilizing a combination of wideband and coherent sources. The methods are applied to Integrated Circuit inspection, to improve overlay measurement techniques, by improving contrast or by 3-D imaging, in single shot imaging.

Title: Methods and apparatus for estimating physical parameters of reservoirs using pressure transient fracture injection/falloff test analysis
Inventor: CRAIG DAVID P
IPC: E21B49/00
Filed: 2005-02-22
Abstract: A before-closure pressure-transient leakoff analysis for a fracture-injection/falloff test is used to mitigate the detrimental effects of pressure-dependent fluid properties on the evaluation of physical parameters of a reservoir. A fracture-injection/falloff test consists of an injection of liquid, gas, or a combination (foam, emulsion, etc.) containing desirable additives for compatibility with the formation at an injection pressure exceeding the formation fracture pressure followed by a shut-in period. The pressure falloff during the shut-in period is measured and analyzed to determine permeability and fracture-face resistance by preparing a specialized Cartesian graph from the shut-in data using adjusted pseudodata such as adjusted pseudopressure data and time as variables in a first method, and adjusted pseudopressure and adjusted pseudotime data as variables in a second method. This analysis allows the data on the graph to fall along a straight line with either constant or pressure-dependent fluid properties. The slope and the intercept of the straight line are respectively indicative of the permeability k and fracture-face resistance evaluations R0.

Patent CA-2576809-A1 (CA)
Inventor: GENIUSZ ANDRZEJ
IPC: H02P9/00
Filed: 2005-07-29
Abstract: The invention relates to a method for controlling the active or reactive power output or input of an induction machine (1) in a coordinate system which is fixed for the winding. According to said method, a first controller (46-1) produces a first controller output variable depending on a nominal variable deviation of the effective power, and a second controller (46-2) produces a second controller output variable depending on a nominal variable deviation of the reactive power. The first and the second controller output variables are impinged upon with respective feedback variables which are functions derived from at least one time-dependent system variable of the induction machine. A  voltage or a current of the induction machine is determined as the correcting variable, without further control, using at least the first and second controller output variables impinged upon by the feedback variables. The feedback variables are adapted to linearize the controlled system and allow restriction to merely two simple controllers, e.g. two PI controllers. The control method can for example be used in double-fed asynchronous machines.
