| 20100152070 | DRILLING LOST CIRCULATION MATERIAL - An engineered composition for reducing lost circulation in a well includes a mixture of coarse, medium and optional fine particles, and a blend of long fibers and short fibers. The long fibers are rigid and the short fibers are flexible. The long fibers form a tridimensional mat or net in the lost-circulation pathway that traps the mixture of particles and short flexible fibers to form a mudcake. The mixture of particles and blend of fibers may be added to water-based and oil-based drilling fluids. The composition, size, and concentration of each component of the mixture of particles and blend of fibers may be fine-tuned for each application. | 06-17-2010 |
| 20110024114 | CEMENT COMPOSITION COMPRISING MIXTURE OF ORGANIC AND INORGANIC FIBRES FOR CURING SEVERE LOSSES ESPECIALLY IN THE RESERVOIR SECTION - Disclosed is a method for controlling loss circulation and simultaneously strengthening a weakened formation when drilling for oil. This invention relates to the permeable subterranean formation and natural and induced fractured formations that encounter severe losses and their treatment with a composition composed of long rigid organic fibre with different type of fibres selected from a category of organic or inorganic fibres along with different particle sizes that orientation of fibres and packing of the solids shows a good blockage effect to resist the loss and later the final set material develop required compressive strength to cure those losses and strengthening the structure. | 02-03-2011 |

| 20100109948 | Methods and Apparatuses For GPS Coordinates Extrapolation When GPS Signals Are Not Available - Systems and methods for extrapolating GPS coordinates beyond line of sight are disclosed. A coordinate extrapolation system (CES) can include a memory, a processor, and a GPS receiver. The CES can receive GPS signals and determine GPS coordinates corresponding to a location. If GPS signals are unavailable, the CES models the surface of the earth and extrapolates the GPS coordinates corresponding to the location at which GPS signals are unavailable. Methods for extrapolating the GPS coordinates and calibrating the CES are also disclosed. | 05-06-2010 |

| 20090075618 | Multi-antenna/multi-receiver array diversity system - The present invention is a system for increasing Signal-to-Noise Ratio (SNR) in a wireless communication system comprising a plurality of antennas each antenna providing a signal, a device for selecting a subset of signals provided by the plurality of antennas, a maximum ratio combiner for summing the selected subset of signals provided by the plurality of antennas, and a decision device for measuring the selected subset of signals against a predefined threshold. The device for selecting the subset of signals is coupled to the plurality of antennas. The maximum ratio combiner is coupled to the selected subset of signals and the decision device for measuring the selected subset of signals against a predefined threshold. The decision device is coupled to the selecting device such that one selected signal of the selected subset of signals is replaced by an unused signal provided by the plurality of antennas. | 03-19-2009 |
| 20100091819 | ARRANGEMENT FOR SYNCHRONIZING ACCESS POINTS IN WLAN USING DIRECT-SEQUENCE SPREAD SPECTRUM SIGNALING - An arrangement for providing synchronization between a number of overlapping area access points within a wireless LAN utilizes a Power over Ethernet (PoE) cable connection to transmit synchronization signals from a centralized hub/switch to each of the access points connected to the cable. The synchronization signal takes the form of a direct sequence spread spectrum (DS-SS) signal that is coupled onto the twisted pair used to provide the low voltage PoE signal to various powered devices. At each access point, a filter is used to remove the synchronization signal from the PoE transport, allowing for the group of access points to share a common beacon signal and allow for frequency re-use among the access points. The DS-SS signal is preferable created by a combination of a baseband signal and a set of separate pseudo noise (PN) sequences defining a precision phase (“pilot tone”) signal, a time mark (superframe/beacon) signal, and a time-of-day (real-time clock) signal. | 04-15-2010 |
| 20100304681 | NARROWBAND INTERFERENCE REJECTION FOR ULTRA-WIDEBAND SYSTEMS - A technique for reducing interference between a direct-sequence ultra-wideband communications system and a narrowband communications system uses interference-rejecting spreading codes to reduce signal power in a frequency band associated with the narrowband communications system. A method of operating an ultra-wideband communications system includes applying an interference-rejecting spreading code to a signal for transmission. The interference-rejecting spreading code is configured to reduce power in a particular frequency band of a transmit or receive power spectral density associated with the ultra-wideband signal without substantially reducing power outside that particular frequency band of the transmit or receive power spectral density associated with the ultra-wideband signal. | 12-02-2010 |
