Patent number: 9844019Abstract: A technique for estimating the location of a wireless terminal at an unknown location in a geographic region is disclosed. The technique is based on the recognition that there are location-dependent traits of electromagnetic signals. In environments where multiple antennas are radiating the same signal, as in the case of distributed antennas or host-repeater configurations, one or more possible locations of the wireless terminal can be designated as improbable based on i) a measure of the propagation delay of a signal traveling between a) a base station and b) the wireless terminal or an infrastructure antenna, or ii) the maximum distance at which a signal is detectable by the wireless terminal. Additionally, the applicable set of values for the location-dependent traits is selected based on similar criteria.Type: GrantFiled: August 12, 2014Date of Patent: December 12, 2017Assignee: Polaris Wireless, Inc.Inventors: Tarun Kumar Bhattacharya, David Stevenson Spain, Jr., Hassan Mohamed El-Sallabi, Robert Lewis Martin

Patent number: 9819081Abstract: The reconfigurable radio direction finder system and method uses a reconfigurable antenna to electronically cycle through a plurality of different antenna configurations to determine a signal direction. Specifically, the reconfigurable antenna is cycled through N different antenna configurations, where N is an integer greater than one, where each antenna configuration has a pointing direction associated therewith defined by an elevation angle ?n of an n-th antenna configuration, where n is an integer between 1 and N, and an azimuthal angle ?n of the n-th antenna configuration. A received signal strength of the radio signal is measured for each of the antenna configurations as a power output of the n-th antenna configuration, Pn.Type: GrantFiled: July 7, 2014Date of Patent: November 14, 2017Assignee: QATAR FOUNDATION FOR EDUCATION, SCIENCE AND COMMINITY DEVELOPMENTInventors: Hassan Mohamed El-Sallabi, Mohamed Mahmoud Abdallah, Khalid Ali Qaraqe, Gregory H.

Patent number: 9784606Abstract: A temperature sensing device comprising a plurality of thermocouples in a hollow tube, where the thermocouples sensing tips contact the outer wall of the tube, and a heat flux source that heats the hollow tube. The hollow tube is inserted through a cross section of a pipe perpendicular to the longitudinal axis of the pipe. The apparatus measures a void fraction in a two-phase flow of a liquid-gas mixture flowing through the pipe. A process of measuring void fraction whereby the hollow tube is heated to an initial temperature, and in the presence of a liquid-gas mixture flow through the pipe the difference is calculated between the initial temperature of the tube and the temperature during liquid-gas mixture flow, to determine the void fraction in the two-phase flow of liquid-gas mixture through the pipe.Type: GrantFiled: November 20, 2015Date of Patent: October 10, 2017Assignee: King Fahd University of Petroleum and MineralsInventors: Wael Hasan Ahmed, Hassan Mohamed Badr

Patent number: 9574880Abstract: A ring laser gyroscope (RLG) includes moveable mirrors and a Micro-Electro-Mechanical Systems (MEMS) actuator coupled to the moveable mirrors to cause a respective displacement thereof that induces a phase modulation on counter-propagating light beams relative to one another. The induced phase modulation creates an optical path difference between the counter-propagating light beams corresponding to a virtual rotation that reduces the lock-in of the RLG.Type: GrantFiled: September 28, 2012Date of Patent: February 21, 2017Assignees: KING ABDULAZIZ CITY FOR SCIENCE AND TECHNOLOGY, SI-WARE SYSTEMSInventors: Diaa A.

Patent number: 9506717Abstract: The multiple shot spear gun includes a central rotary shaft having a plurality of relatively stationary spear launching tubes or barrels distributed therearound in a cylindrical pattern. The number of spear launching tubes or barrels is not limited, but may comprise any practicable number. Rotation of the central shaft causes a disc to rotate. The disc has a ramp or tang thereon that sequentially engages the trigger of each of the spear launchers as the disc is rotated. A safety disc is rotated with rotation of the central shaft. The safety disc includes a plurality of holes therein. A spring-loaded catch engages one of the holes as the disc rotates with rotation of the central shaft. Thus, the operator of the multiple shot spear gun must release the safety catch after each shot to rotate the central shaft further for the next shot.Type: GrantFiled: December 31, 2014Date of Patent: November 29, 2016Assignee: KING ABDULAZIZ UNIVERSITYInventor: Hassan Mohammed H. Jaber

Patent number: 9323693Abstract: Caching of an immutable buffer that has its data and address prevented from changing during the lifetime of the immutable buffer. A first computing entity maintains a cache of the immutable buffer and has a strong reference to the immutable buffer. So long as any entity has a strong reference to the immutable buffer, the immutable buffer is guaranteed to continue to exist for the duration of the strong reference. A second computing entity communicates with the first computing entity to obtain a strong reference to the immutable buffer and thereafter read data from the immutable buffer. Upon reading the data from the cache, the second computing entity demotes the strong reference to a weak reference to the immutable buffer. A weak reference to the immutable buffer does not guarantee that the immutable buffer will continue to exist for the duration of the weak reference.Type: GrantFiled: January 4, 2013Date of Patent: April 26, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Jinsong Yu, Andrew E. Goodsell, F. Soner Terek, Christopher Wellington Brumme, Ahmed Hassan Mohamed

Patent number: 9189446Abstract: The environment and use of an immutable buffer. A computing entity acquires data or generates data and populates the data into the buffer, after which the buffer is classified as immutable. The classification protects the data populated within the immutable buffer from changing during the lifetime of the immutable buffer, and also protects the immutable buffer from having its physical address changed during the lifetime of the immutable buffer. As different computing entities consume data from the immutable buffer, they do so through views provided by a view providing entity. The immutable buffer architecture may also be used for streaming data in which each component of the streaming data uses an immutable buffer. Accordingly, different computing entities may view the immutable data differently without having to actually copy the data.Type: GrantFiled: January 4, 2013Date of Patent: November 17, 2015Assignee: Microsoft Technology Licensing, LLCInventors: Jason Todd Hunter, Jinsong Yu, Martin Taillefer, Gregory Michael Neverov, Dmitry Kakurin, Ahmed Hassan Mohamed, John J.
