Patent number: 9863188Abstract: 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.Type: GrantFiled: April 14, 2017Date of Patent: January 9, 2018Assignees: King Fahd University of Petroleum and Minerals, King Abdulaziz City for Science and TechnologyInventors: Moustafa Elshafei, Amar Khoukhi, Abdulaziz Al-Maged, Mohammad Talib

Publication number: 20160023755Abstract: A system and method of controlling quadrotor air vehicles (QRAV) that may include an additional two degrees of freedom for each of the four propellers of the QRAV. Each of the four rotors may be allowed to rotate (tilt) around two local axes selected from the x-axis (roll), y-axis (pitch), and z-axis (yaw). Control of the quadrotor including the additional two degrees of freedom allows thrust of each rotor to be direct in any direction of a semi-sphere. As a result, total control inputs of the QRAV may be increased to twelve, enabling smooth control to achieve superior and precise maneuverability. Additionally, the system and method is fault tolerant and capable of handling failures of any of the rotors. Commands to the propellers may be fully decoupled and achieved independently thereby giving pilots better control to execute difficult maneuvers.Type: ApplicationFiled: May 5, 2014Publication date: January 28, 2016Applicant: King Fahd University of Petroleum and MineralsInventors: Moustafa Elshafei Ahmed Elshafei, Mahmoud Abdelmagid Elfeky, Abdul-Wahid Abdul-Aziz Saif, Sami El ferik, Mohammad Fahad Al-Malki

Patent number: 9068873Abstract: 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.Type: GrantFiled: February 14, 2012Date of Patent: June 30, 2015Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Moustafa Elshafei, Fouad Al-Sunni, Sami El-Ferik

Publication number: 20140067394Abstract: 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.Type: ApplicationFiled: August 28, 2012Publication date: March 6, 2014Applicants: KING ABDULAZIZ CITY FOR SCIENCE AND TECHNOLOGY, KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: DIA EDDIN M.
