Abstract: A transverse induction transmitter on an instrument induces currents in an earth formation when it is pulsed. Transient measurements made at transverse and axial receivers are used for determination of a distance to a bed boundary. This may be used to control the drilling direction.

Abstract: A method is disclosed for producing a modified eukaryotic cytoplasmic DNA virus by direct molecular cloning of a modified DNA molecule comprising a modified cytoplasmic DNA virus genome. The inventive method comprises the steps of (I) modifying under extracellular conditions a DNA molecule comprising a first cytoplasmic DNA virus genome to produce a modified DNA molecule comprising the modified cytoplasmic DNA virus genome; (II) introducing the modified DNA molecule into a first host cell which packages the modified DNA molecule into infectious virions; and (III) recovering from the host cell virions comprised of the modified viral genome. The host cell is infected with a helper virus which is expressed to package the modified viral genome into infectious virions. Examples of packaging a modified poxvirus genome by a helper poxvirus of the same or different genus are described. Also disclosed are novel poxvirus vectors for direct molecular cloning of open reading frames into a restriction enzyme cleavage site that is unique in the vector. In one model poxvirus vector, the open reading frame is transcribed by a promoter located in the vector DNA upstream of a multiple cloning site comprised of several unique cleavage sites.

Granted: 2010-02-09
Abstract: A candle assembly includes a melting plate, a wick holder, and a fuel element that fits over the wick holder. The wick holder engages the melting plate preventing the accidental removal thereof from the melting plate. The fuel element is configured to facilitate successful initial ignition and sustained burn of the wick by having a duct dimensioned to ensure that melted fuel material engages the wick when dripping down the duct. The fuel element may also contain an outer shell of fuel material surrounding an inner core of fuel material having different properties than the fuel material of the outer shell. The wick holder includes a wick extending from a sleeve. The sleeve having a constricted portion that reduces an effective capillary fluid flow capacity of the wick and may thereby regulate how quickly fuel is consumed when the candle assembly is burning. A capillary well disposed between the wick holder and the melting plate may be adapted to promote a successful relight after an initial burn of the candle assembly. The candle assembly, may be adapted to promote laminar air flow thereacross during a burn in a substantially calm atmospheric environment.

Granted: 2011-10-18
Abstract: A method and apparatus for selecting one of a plurality of multi-band access points (APs) to associate with a multi-band wireless transmit/receive unit (WTRU) are disclosed. The multi-band APs broadcast frequency band information regarding multiple frequency bands on which the multi-band AP is configured to operate. The multi-band WTRU selects a particular multi-band AP to associate with and a frequency band to use to communicate with the selected multi-band AP based on the frequency band information. If the multi-band WTRU receives frequency band information from the selected multi-band AP which indicates that a characteristic, (e.g., throughput, path loss, load, capacity, backhaul), of the selected frequency band is unacceptable, the multi-band WTRU  determines whether to disassociate with the selected multi-band AP or to continue to associate with the selected multi-band AP via a different frequency band.

Abstract: A block transform-based digital media codec uses a transform coefficient prediction that takes into account a dominant directionality of the digital media data (e.g., an image with strong horizontal or vertical features), and further operates compatibly with a two-stage transform. For DC and DCAC  coefficients from an inner stage transform of a macroblock, the codec calculates and compares directionality metrics based on inner stage transform DC coefficients of neighboring macroblocks to determine dominant directionality. For DCAC coefficients from an outer stage transform of blocks within the macroblock, the codec calculates and compares directionality metrics based on the inner stage transform DCAC coefficients of the macroblock to detect dominant directionality. The determination of directional dominance can also take into account information from other channels (e.g., chrominance as well as luminance).
