Methods for Estimating Location Using Signal with Varying Signal Speed

Номер: US20120004889A1

Автор: John Louis Spiesberger

Принадлежит: Individual

Robust methods are developed to provide bounds and probability distributions for the locations of objects as well as for associated variables that affect the accuracy of the location such as the positions of stations, the measurements, and errors in the speed of signal propagation. Realistic prior probability distributions of pertinent variables are permitted for the locations of stations, the speed of signal propagation, and errors in measurements. Bounds and probability distributions can be obtained without making any assumption of linearity. The sequential methods used for location are applicable in other applications in which a function of the probability distribution is desired for variables that are related to measurements.

A model simulating the evolutionary dynamics of events or processes includes a non linear adaptive mathematical system simulating the spatial and temporal dynamics of the event or processes by using measured values of a certain number of parameters describing the evolutionary condition of the event or process at certain different times. The values of such parameters are measured at a first time and at least a second time different from and following the first time. The model enables the definition of a n-dimensional array of points in a n-dimensional reference system having an axis that represents the values of the parameters being measured, the parameters in the array being represented by special points in the array of points. The displacements of each of the points of the array of points are computed as a function of the displacements in the array of points of each of the points representing the measured parameter values between a first time of measurement and at least a successive second time of measurement and as a function of the distance of each of the points of the array of points from each of the points representing the measured parameters. The evolution of the event and or the model in time is visualized by displaying the points of the array of points at different times.

A computer system and method of automatically generating a Local Grid Refinement (LGR) gridded model of a gas reservoir. A geologic file includes information identifying the locations of one or more wells according to root grid cells within a volume of the earth to be modeled. User inputs specify the number of hydraulic fractures from each well, and such parameters as the fracture length, etc. User inputs also specify the number of “splits” of the root grid cells containing hydraulic fractures; those root grid cells are then split into finer resolution grid cells of increasing width within the root grid cells containing the fractures. For horizontal wells, user inputs indicate the number of splits of root grid cells containing the lateral portions of the wellbore. Non-orthogonal and complex fractures are processed by a “nested” LGR approach. Geologic properties are assigned to each grid cell, with a tensorial adjustment included for non-orthogonal fractures, and the resulting model is available for simulation. 1.

This invention encompasses embodiments for multi-modal integrated simultaneous measurement of various aspects of fluids contained in circulating systems such as automotive reciprocating engines and vehicle transmissions. These circulating systems perform constant internal lubrication, and heat and contaminant removal to protect the internal moving parts from the inherent friction and damage in normal operation. Most commonly this is achieved with fluids based on hydrocarbon and/or related synthetics, which, over time, can lose their protective properties, and vary in their performance or breakdown/decay due to internal and external events. Several components within the lubricant fluid can be measured and can provide insight into the efficacy of the system to perform its designed mission. Described herein is a real-time, simultaneous, integrated, multi-modal sensor system for early warning notification that can be further enhanced using specifically designed nanoparticles that can be introduced into the system, engineered to specifically bind with the contaminants and/or undergo an irreversible state change upon certain experienced conditions to both increase the detectability as well as provide for a framework to improve filter performance.

Embodiments provide histogram-based methods and system to estimate the transfer function of an ADC, and subsequently to linearize a non-linear ADC transfer function. Embodiments include blind algorithms that require no a priori knowledge of the input signal distribution. Embodiments can be implemented using cumulative (i.e., cumulative distribution function (CDF)) or non-cumulative (i.e., probability density function (PDF)) histograms. According to embodiments, a non-linear transfer function can be estimated by linearly approximating successive local intervals of the transfer function. Linearly approximated successive local intervals of the transfer function can then be used to fully characterize and closely estimate the transfer function.

A device and method for LADAR ranging using relatively long laser pulse widths and slower system clock speeds is provided. The center points of the sent and received laser signal such as Gaussian laser pulses are identified by time sampling the sent and received laser signal waveforms at predetermined time positions. The signal energy within each time sample of the respective sent and received laser signals defines a clock “bin”. The received laser signal generates an output from a photodetector cell on a focal plane array that is converted into voltage. The signal energy is integrated using a capacitor array for each of the clock bins and is representative of the signal energy in each time sample. The output of the capacitor array is collected in buffer and digitized. Signal processing means extracts the center of the transmitted and received pulses and the time-of-flight calculated as the time between the transmitted and returned centers of the laser signal pulses.

Принадлежит: Individual

Original Pi Estimating Method (PEM) Algorithm is primarily intended for computer application. PEM Algorithm, given in ‘word format’, describes a math process suitable for programming. Using sufficient pi truncations and the set of all real numbers for domain divisions, PEM math process permits a user to specify goal-precisions and to estimate goal-displacements in ALL dimensional-space, domains and ranges, particularly, for ALL infinitesimal space, including beyond quantum values. By use of super-computer, PEM Algorithm can be combined with appropriate interface to control high energy devices for consistent, precise, repeatable values. Uncertainty and probabilities, involved during microscopic, infinitesimal displacements, require precise and repeatable estimates within atomic, sub-atomic, and beyond—domains. Since PEM provides reliable, repeatable, estimates of pi approximations close to actual displacements: probabilities increase and uncertainties lessen. Not to be overlooked, self-contained, binary hardware, PEM Devices involve vastly numerous configurations and unlimited sizes.

A method for predicting polarization mode dispersion (PMD) in an installed optical fiber. Values of PMD are measured for a first optical fiber at various points in time during the manufacture and installation of the first optical fiber. Values of PMD are identified that correspond to sensitive ones of the various points in time. A set of correlation coefficients is calculated based on the values of PMD corresponding to the sensitive ones of the various points in time. An installed value of PMD for a second optical fiber is predicted based on the set of correlation coefficients.
