Patent GB-2409610-A (GB)
Title: Network acquisition in accordance with one of a plurality of radio access technologies
Inventor: ORMSON RICHARD
IPC: H04W88/06
Filed: 2003-12-23
Abstract: A mobile radio communications device is arranged for connection to networks of at least two radio access technologies (RATs), such as GSM and WCDMA, operating with at least partially overlapping frequency bands. Signal characteristics of the common frequency bands are determined and an attempt is made to connect on a first of the frequency bands in accordance with a first of the RATs. If the attempt fails, an attempt is made to connect to the same frequency band in accordance with a second of the RATs before attempting to correct to a second of the frequency bands. In an alternative arrangement, the mobile device may scan a plurality of frequency bands and identify a block of bands having a uniform characteristic, implying that a WCDMA system has been found. Then, the mobile device may attempt to connect at a centre frequency of the identified block of bands.

Title: A dynamic seal assembly, a seal assembly, a drill bit and an earth-boring bit.
Inventor: YONG ZHOU
IPC: E21B10/25
Filed: 2004-07-26
Abstract: Disclosed is a seal assembly for dynamically sealing between rotatable members such as a rolling cone of a rock bit. The assembly includes a seal ring having a facing surface (60) of a relatively hard material, such as hardened steel or tungsten carbide, and a second seal ring (52) of a softer material, the softer material being harder, however, than typical elastomers. Suitable materials for the relatively soft seal ring (52) include tin, copper, aluminum, magnesium, lead and alloys thereof, as well as non-metallic materials such as nylon-zytel, acetal, and polypropylene. The relatively soft seal ring (52) may be affixed to a third seal ring or maybe affixed directly to the cone steel, for example. The seal assembly provides potential for longer life relative to elastomeric seals and requires less axial space along the journal surfaces than certain conventional metal seal assemblies.

IPC: E21B47/12
Filed: 2004-10-01
Abstract: The invention generally relates to apparatus and methods for instrumentation associated with a downhole deployment valve 110 or a separate instrumentation sub. In one aspect, a DDV 110 in a casing string is closed in order to isolate an upper section of a wellbore 130 from a lower section 120. Thereafter, a pressure differential above and below the closed valve is measured by downhole instrumentation to facilitate the opening of the valve. In another aspect, the instrumentation in the DDV 110 includes sensors placed above 128 and below 130 a flapper 230 portion of the valve 110. The pressure differential is communicated to a control unit 107 at the surface of the well for use in determining what amount of pressurization is needed in the upper portion to safely and effectively open the valve. Additionally, instrumentation associated with the DDV can include pressure, temperature, and proximity sensors to facilitate the use of not only the DDV but also telemetry tools. There are additional disclosures of information transferring, operating and communication methods.

Title: Dynamic Optimisation of Block Transmissions for Interference Avoidance
Inventor: COON JUSTIN
IPC: H04L25/03
Filed: 2006-04-03
Abstract: An OFDM block or single- or multi-carrier Ultra Wideband (UWB) transmission system achieves Interference Avoidance (IA) between broadband and narrowband signals (Fig. 1) by dynamically shaping the broadband signal spectrum via the application of a Time-Domain (TD) envelope function to each block before Inverse Fourier Transformation (IFFT), which minimises broadband transmission in those frequencies containing the narrowband signal. IA optimisation of the TD envelope function, under constraints such as peak-average power ratio or dynamic range, requires no extra information at the receiver ("blind detection/adaptation") and can be performed by a numerical iterative method such as Newton, barrier or primal dual, whose stopping criteria can be tuned. The data loss suffered by fixed length transmissions in Frequency Domain (FD) Active Interference Cancellation (AIC) is thus avoided.

Title: Apparatus for handling a perforating gun
Inventor: NORDAAS LARS B
IPC: E21B17/042
Filed: 2004-06-08
Abstract: A sealed perforating gun assembly 22 for use with automatic pipe handling equipment on oil and gas drill rigs. An upper sealed connector 24 and a lower sealed connector 26 have sealed threaded connections for mating with ends of a perforating gun 18. The connectors have external dimensions equivalent to the external dimensions of standard drill pipe and have standard tapered thread couplings. Ignition transfer explosives are carried within cavities in the connectors. The cavities are sealed on their drill pipe coupling ends. The ignition transfer explosives are adapted to penetrate the seals so that ignition can be transferred between the gun assembly and adjacent sections of the gun string. Since the external dimensions of the sealed connectors correspond to the external dimensions of drill pipe, automatic drill pipe handling equipment can handle the gun assemblies.
