Inventor: GORE DHANANJAY ASHOK
IPC: H04L27/26
Filed: 2008-01-03
Abstract: Techniques for transmitting pilot and for processing received pilot to obtain channel and interference estimates are described. A terminal may generate pilot symbols for a first cluster in a time frequency block based on a first sequence and may generate pilot symbols for a second cluster in the time frequency block based on a second sequence. The first and second sequences may include common elements arranged in different orders and may be considered as different versions of a single sequence. The terminal may transmit the pilot symbols in their respective clusters. A base station may obtain received pilot symbols from multiple clusters in the time frequency block. The base station may form each of multiple basis vectors with multiple versions of the sequence assigned to the terminal and may process the received pilot symbols with the multiple basis vectors to obtain a channel estimate for the terminal.

Title: Sectorized base stations as multiple antenna systems
Inventor: PARIZHSKY VLADIMIR
IPC: H04B7/04
Filed: 2008-05-27
Abstract: Methods and apparatus for improved utilization of air link resources are discussed in wireless communications systems employing multi-sector base stations and wireless terminals with multiple antennas. Timing synchronization is maintained across the base station sectors, and the same set of tones are used in adjacent sectors. In a sector boundary region, which is typically a high interference region, a wireless terminal is set to a sector pair state and operated in a MIMO mode of operation, communicating with two adjacent base station antenna faces of the same base station concurrently, the two different adjacent base station antenna faces corresponding to different adjacent sectors. Thus, typically high interference sector boundary regions, are converted into high capacity regions by having the sectors coordinated and utilizing MIMO techniques.

Inventor: ILLFELDER HERBERT M J
IPC: E21B47/00
Filed: 2008-05-02
Abstract: A method for determining a list of survey points for a drilling well includes a feedback loop in which one or more measured parameters are compared with computed or derived parameters. The computed parameters are typically obtained from other/additional measurements. For example, in one exemplary embodiment of the invention, a magnetic least distance vector determined via magnetic ranging is compared with a geometric least distance vector computed from conventional borehole surveying measurements. Estimates of the drilling well azimuth and/or inclination may be adjusted to yield a good agreement between the magnetic and geometric least distance vectors. Exemplary embodiments of the present invention advantageously provide for a substantially real-time determination of a definitive well path for a drilling well as well as a substantially real-time relative placement of the drilling well with respect to a target well.

Title: Verification methods and apparatus for use in providing application services to mobile communication devices
Inventor: SHERKIN ALEXANDER
IPC: H04W12/06
Filed: 2009-12-04
Abstract: A mobile communication device operates in a wireless communication network with use of a communication service provided by a service provider (e.g. a wireless carrier for voice telephony, or data service provider for data synchronization). An application server receives, via the wireless network, a message from the mobile device. The message has a field for inclusion of a token having a digital signature corresponding to the service provider. The application server performs token validation of the message, which includes a verification step for verifying the digital signature of the token with a public key corresponding to the service provider. The application server then grants or denies access to an application service depending on the outcome of the token validation. In one embodiment, the application service is an e-commerce transaction service, wherein a proof-of-work (POW) test (e.g. a Captcha test) otherwise utilized for the service is bypassed or excluded.

Inventor: NENNIGER JOHN
IPC: E21B43/22
Filed: 2009-12-21
Abstract: An in situ extraction process for heavy oil reservoirs using solvent comprises removing liquids and gases from areas contacting with the heavy oils to increase an interfacial area of unextracted heavy oil contactable by the solvent. Solvent vapour is injected into the areas to raise the reservoir pressure until sufficient liquid solvent is present to contact the increased interfacial area. The reservoir is shut in for a sufficient time for the solvent to diffuse into the unextracted oil across the interfacial area in a ripening step to create a reduced viscosity blend of solvent and oil. One or more reservoir characteristics is measured to confirm the extent of solvent dilution that has occurred of the unextracted oil in the reservoir. Gravity drainage based production is commenced from the reservoir upon the blend having a viscosity low enough to permit the blend to drain through the reservoir to a production well.
