Title: A digital adaptive predistorter for counteracting memory effect in RF power amplifiers
Inventor: MCBEATH SEAN M
IPC: H03F1/26
Filed: 2004-11-29
Abstract: A digital predistorter comprises a cascade of sections 201-207 updated by an analyzer 117. The input signal is supplied to an "amplitude memory-subtracted signal calculator" 201 which models the amplitude error in the power amplifier output caused solely by memory effects and then subtracts this memory-effect error from the input signal (figure 3). Section 203 is a conventional amplitude predistortion block. Section 205 is an optional phase predistortion section which compensates for both memoryless and memory effect distortion in the amplifier's phase response. The input correction filter 207 predistorts the signal to remove the linear effects that are a function of the input signal frequency. No computation of the inverse of an amplifier model including memory effects is required.

Title: Measurement-while-drilling assembly using real-time toolface oriented measurements
Inventor: CAIRNS PAUL GERARD
IPC: E21B47/00
Filed: 2003-07-30
Abstract: This invention provides a measurement-while-drilling (MWD) downhole assembly for use in drilling boreholes which utilizes directional formation evaluation devices on a rotating assembly in conjunction with toolface orientation sensors. The data from the toolface orientation sensors are analyzed by a processor and toolface angle measurements are determined at defined intervals. Formation evaluation sensors operate substantially independently of the toolface orientation sensors and measurements of the formation evaluation sensors are analyzed in combination with the determined toolface angle to obtain formation parameters.

Abstract: A stator assembly for an electric motor includes a stator housing 32, an expandable flux ring 34 inserted into the stator housing and a plurality of magnets 36 on an inner surface of the flux ring. Overmould material is moulded around the magnets in the flux ring, such as by injection moulding, the overmould material being moulded to form at least one of a commutator end or rear bearing support 102, front bearing support 103 and fan baffle 104.. The pressure of the overmould material as it is being moulded expands the flux ring pressing the flux ring into engagement with the stator housing. The overmould material secures the magnets to the flux ring and the flux ring to the housing. One of the flux ring and stator housing has a dimple that engages a hole in the other of the flux ring and stator housing to align the flux ring and stator housing. In an aspect, the overmould material is moulded to form a keying feature. The keying feature can be slots of different widths between magnetic poles of the stator assembly. In an aspect, the flux ring and housing are preformed as a unit by stamping them from blanks and rolling them together. In a variation, the flux ring blank is rolled first to form the flux ring and the housing blank rolled around the flux ring with the flux ring acting as a rolling arbor.

Title: Fragmentation of ions within RF ion traps by electron transfer dissociation
Inventor: HARTMER RALF
IPC: H01J49/02
Filed: 2006-01-27
Abstract: The invention relates to the fragmentation of large molecular analyte ions, preferably biopolymer ions, by reactions between multiply charged positive analyte ions and negative reactant ions in RF ion traps. Some of these reactions involve electron transfer reactions with subsequent dissociation of the analyte ions, and some involve the loss of a proton leading to stable product ions. The invention can use linear 2D RF ion traps, but preferably three dimensional RF quadrupole ion traps. In 3D Paul traps of this type, electron transfer reactions take place with a sufficiently high yield because ions that remain stable as radical cations in the reactions after the transfer of an electron are further fragmented by collisionally induced fragmentation, forming fragment ions typical of electron transfer dissociation (ETD). Preferably both positive and negative ions are introduced to the RF ion trap sequentially through the same aperture.

Title: Acoustic echo sounder for locating and quantifying a target
Inventor: NISHIMORI YASUSHI
IPC: G01S15/96
Filed: 2006-03-20
Abstract: An acoustic echo sounder, particularly used as a fish finder, includes a plurality of transducer elements 41a-41n with associated circuits 4a-4n for detecting acoustic echoes reflected from a sounding area. A receiver 1 includes a first detector 10 for detecting a target region (i.e. the direction of the target) and a second detector 20 for determining quantitative data about the target (e.g. quantity of fish in a school). The first detector 10 causes the signal intensity data to saturate to a certain extent while maintaining information on directions of the target. The second detector 20 amplifies the echo signals from the individual circuits 4a-4n while maintaining a quantitative relationship between one echo signal and another, which does not cause the signal intensity data to saturate. A data synthesiser 16 outputs data to a display 2 which presents an echo sounding picture based on the signal intensity data obtained by the first detector 10 together with the quantitative data (e.g. fish quantity) obtained by the second detector 20.
