Title: Pilot transmission schemes for wireless multi-carrier communication systems
Inventor: MALLADI DURGA PRASAD
IPC: H04W24/08
Filed: 2004-01-07
Abstract: Pilot transmission schemes suitable for use in wireless multi-carrier (e.g., OFDM) communication systems. These pilot transmission schemes may utilize frequency, time, or both frequency and time orthogonality to achieve orthogonality among the pilots transmitted by multiple base stations on the downlink. Frequency orthogonality is achieved by transmitting pilots on disjoint sets of subbands. Time orthogonality is achieved by transmitting pilots using different orthogonal codes (e.g., Walsh codes). The pilots may also be scrambled with different scrambling codes, which are used to randomize pilot interference and to enable identification of the transmitters of these pilots. Pilot interference cancellation may be performed to improve performance since subbands used for data transmission by one transmitter may also be used for pilot transmission by another transmitter. Pilot interference is estimated and then subtracted from received symbols to obtain pilot-canceled symbols having improved quality.

Abstract: A route information transmitting method for correctly communicating a recommended route or guide route with an irreducible minimum amount of data to the receiving side. The transmitting side arithmetically processing position data on locations along a route to convert the data into data including statistical deviation, encodes the data into variable length codes, and provides the thus produced compressed data to the receiving side who has requested information on the route. The receiving side decodes the compressed data, restores the position data, and specifies the route by map matching.  Thus, route information can be correctly transmitted with a small amount of data.

Title: Simultaneous development of underground caverns and deposition of materials
Inventor: LANDRY DAVID CHARLES
IPC: B09B1/00
Filed: 2004-10-14
Abstract: A method is provided for simultaneously developing caverns while depositing wastes or other materials in them. A well is first drilled into a salt formation and the development of a salt cavern by means of solution mining is initiated. When the development of the cavern has been carried out to an extent sufficient to accommodate the injection of a prescribed amount of wastes or other materials, injection of the wastes or other materials through the well is started while continuing to develop the cavern by solution mining.  The injection of the wastes or other materials may be carried out continuously or intermittently. The proportion and rates of wastes or other materials and mining water injected into the well are monitored and regulated so that cavern development continues at a rate that allows the cavern to reach an intended prescribed size while the wastes or other materials are injected and deposited into the cavern.

Abstract: A method for controlling the motion of marine vessel (10) comprises mounting a gyroscope (12) in a gimbal and fixing the gimbal inside the vessel. In one arrangement, a trunnion axis (18) of the gimbal is mounted athwart the vessel (10). Sensors (20) are mounted at various locations on the vessel (10), as well as on the gyroscope (12), to measure the moton of the vessel (10), including motion caused by wave action. Signals from the sensors (20) are processed by a computer that in turn controls a motor to apply a force about the trunnion axis (18) to the gyroscope (12) in a direction that causes the gyroscope (12) to provide a reactive torque urging the vessel (10) to follow the slope of the wave and reduce the motion in the vessel (10). Thus, the method causes the gyroscope to apply reactive force that causes the vessel (10) to follow the slope of the waves acting on the vessel. This in essence eliminates hydrodynamic and hydrostatic force on the vessel and therefore prevents resonance of the vessel (10) with the waves.
