20090143926 | Method and apparatus for tracking center of gravity of air vehicle - The method and apparatus for tracking a center of gravity (COG) of an air vehicle provides a precise calculation and updating of the COG by disposing a plurality of acceleration measuring devices on a circumference of one or more rings in a manner that establishes redundancy in acceleration measurement. A multivariable time-space adaptive technique is provided within a high speed digital signal processor (DSP) to calculate and update the position of the COG. The system provides the capability of executing a procedure that reduces dispersion in estimating angular velocities and lateral accelerations of a moving vehicle and corrects the vehicle's estimated angular velocities and lateral accelerations. In addition, a consistency check of the measured values from the acceleration measuring devices is performed to assist in fault detection and isolation of a faulty accelerometer in the system. | 06-04-2009 |
20090240376 | System and method for controlling flow characteristics - The system for controlling flow characteristics allows a user to selectively modify the inherent fluid flow characteristics of a fluid transmission system including a flow process controller and a control valve positioner. The system includes a programmable flow controller having an input adapted for receiving an input signal from the flow process controller. The programmable flow controller selectively modifies the input signals generated by the flow process controller depending upon user-selectable flow parameters. An output is in communication with the programmable flow controller, with the output being adapted for transmitting output signals to the control valve positioner (and the valve connected thereto). A user interface is provided for inputting the user-selectable flow parameters to the programmable flow controller for modification of the input signal to the user-selectable flow parameters. | 09-24-2009 |
20100185436 | Arabic poetry meter identification system and method - The Arabic poetry meter identification system and method produces coded Al-Khalyli transcriptions of Arabic poetry. The meters (Wazn, Awzan being forms of the Arabic poems units Bayt, Abyate) are identified. A spoken or written poem is accepted as input. A coded transcription of the poetry pattern forms is produced from input processing. The system identifies and distinguishes between proper spoken poetic meter and improper poetic meter. Error in the poem meters (Bahr, Buhur) and the ending rhyme pattern, “Qafiya” are detected and verified. The system accepts user selection of a desired poem meter and then interactively aids the user in the composition of poetry in the selected meter, suggesting alternative words and word groups that follow the desired poem pattern and dactyl components. The system can be in a stand-alone device or integrated with other computing devices. | 07-22-2010 |
20120211001 | SYSTEM AND METHOD FOR AUTOMATIC POSITIONING OF A SOLAR ARRAY - The system and method for automatic positioning of a solar array utilizes modular neural processors pre-trained from existing solar data to estimate the direction of the sun at any location and at any time, irrespective of the orientation or movement of the base unit, and to determine solar panel servo tracking system steering commands for optimal orientation of the solar panel surfaces towards the sun. The automatic positioning system may be used in power generation or water desalination facilities. The device integrates a GPS system, an electronic compass, and an inclination sensor for determination of the orientation of the base unit. Periodic control commands are issued to conventional servo systems for automatic steering of a solar array for maximum solar power acquisition to optimize energy gain versus energy consumption in steering. | 08-23-2012 |
20130012807 | SYSTEM AND METHOD FOR TRACKING POSITION OF HANDHELD MEDICAL INSTRUMENTS - The system and method for tracking the position of handheld medical instruments provides for instantaneous feedback and instruction to a medical practitioner during performance of a medical procedure. The system and method utilize a graphical user interface, which displays data related to at least a portion of a patient's body. The user then selects a body part of the patient for performing a selected medical procedure. A plurality of pulse receivers are provided for detecting and receiving very narrow pulse electromagnetic pulses. A plurality of instrument pulse emitters are mounted on a handheld medical instrument for selectively transmitting first very narrow pulse electromagnetic pulses, and a to plurality of patient pulse emitters are positioned on the selected body part of the patient for selectively transmitting second very narrow pulse electromagnetic pulses. The position and orientation of the handheld medical instrument with respect to the selected body part is then determined. | 01-10-2013 |
20130211746 | MULTIPHASE FLOW MEASUREMENT SYSTEM AND METHOD - The multiphase flow measurement system and method includes video sensors and illumination along a pipe upstream, and a similar arrangement of sensors and illumination downstream displaced from the first location by a known distance utilized for velocity calculation between images at both locations. Image capturing and processing is done from video data at both locations. Objects corresponding to each flow phase in the video images are characterized and sorted by size, color, spectral properties, shapes, and pattern features using automatic pattern recognition. Image cross-correlation and pattern recognition are applied to each group of objects corresponding to one or more flow phases to estimate the velocity of each phase based on the delay calculation. Flow velocity is calculated from the weighted average of the phase velocities. Overall flow type is estimated using the estimated phase velocities and the areas occupied by the objects corresponding to each phase in the images. | 08-15-2013 |
20130318016 | METHOD OF PREDICTING GAS COMPOSITION - The method of predicting gas composition in a multistage separator includes solutions to the regression problem of gas composition prediction that are developed using an ensemble of hybrid computational intelligence (CI) models. Three separate homogeneous and one heterogeneous ensemble of hybrid computational intelligence (EHCI) models are developed using a parallel scheme. The homogeneous models have the same types of CI models used as base learners, and the heterogeneous model has of different types of CI models used as base learners. Various popular CI models, including multi-layer perceptron (MLP), support vector regression (SVR) and adaptive neuro-fuzzy inference system (ANFIS), are used as base learners of ensemble models. | 11-28-2013 |
20140067394 | SYSTEM AND METHOD FOR DECODING SPEECH - The system and method for speech decoding in speech recognition systems provides decoding for speech variants common to such languages. These variants include within-word and cross-word variants. For decoding of within-word variants, a data-driven approach is used, in which phonetic variants are identified, and a pronunciation dictionary and language model of a dynamic programming speech recognition system are updated based upon these identifications. Cross-word variants are handled with a knowledge-based approach, applying phonological rules, part-of-speech tagging or tagging of small words to a speech transcription corpus and updating the pronunciation dictionary and language model of the dynamic programming speech recognition system based upon identified cross-word variants. | 03-06-2014 |
