Abstract: A directional drilling system consisting of a four-motor drilling head for better steering in directional drilling and vertical/horizontal drilling is developed. The rotational speed of each motor is independently controlled. The use of four motors in coordination with other traditional drilling variables allow precise control of the drilling direction and optimization of the rate of penetration (ROP). The top and right motors rotate in opposite directions to the bottom and left rotors to stabilize the roll rotation of the drilling head. Inclination (pitch) movement is obtained by increasing/decreasing the speed of the top motor while decreasing/increasing the speed of the lower motor. The Azimuth (yaw) movement is obtained similarly using the right and left motors. The drilling power is derived from down hole motors. A drill string transmits the drilling fluid and force on bit.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
