Title: Marine seismic sound source with capacitor and control system mounted close to coil
Inventor: JOPLING JOHN MURRAY
IPC: G01V1/157
Filed: 2003-02-24
Abstract: A boomer for generating acoustic signals in a marine seismic survey has a frame 14 towed by a survey vessel. A coil 16 (or coils) of square or rectangular cross section (to improve packaging density) wires is mounted on the frame 14 and a conductive plate 17 is adjacent to the coil. An insulating flexible membrane protects the coil and the plate. One or more capacitors are mounted on the frame (rather than conventionally on the survey vessel), and a control system (switches, current and potential controllers) deliver a regulated charge from the capacitor(s) to the coil which causes the plate to move. This allows the boomer to operate on a lower voltage (eg 1000 V) and use power cables of reduced size and weight. Inductive power losses along long power cables are thus avoided. Since the boomer is more compact it can be used in focussed arrays.
Patent GB-2382716-A (GB)
Title: Ion implantation beam monitor
Inventor: MITCHELL ROBERT JOHN CLIFFORD
IPC: H01J37/317
Filed: 1998-07-21
Abstract: As a rotating spoked substrate wheel of a ion implanter passes across a beam stop during a scan cycle, a series of pulses are generated by the beam stop. These pulses are analysed to determine characteristics about the ion beam such as uniformity, width and height. A digital signal processor samples the beam stop current I (BEAMSTOP)  at regular intervals. By comparing the magnitude of successive samples, a dose uniformity map may be generated, so that identification of particular substrates on the wheel which have been dosed incorrectly is possible. The time taken for the beam to move between two points during the scan can also be measured from the sampled beam stop current. This provides a measurement of ion beam width. Similarly, by measuring, from the sample beam stop current, the time taken for the ion beam to pass between the middle of two adjacent substrates, the beam height may be ascertained.

Title: Improved gamma-ray camera system
Inventor: RAMSDEN DAVID
IPC: G01T1/164
Filed: 2003-03-11
Abstract: A scintillator crystal based gamma-ray camera system is described. The gamma-ray camera system includes a spectra processing component for providing improved energy resolution over that seen in conventional gamma-ray camera systems. The spectra processing component operates to deconvolve detector response functions from observed energy spectra on a pixel by pixel basis. The pixel dependent detector response functions are obtained by a combination of theoretical simulation, and empirical calibration. By deconvolving pixel specific detector response functions, variations in response of a gamma-ray camera system across its image plane can be accounted for. This offers significant improvements in energy resolution and many of the problems associated with conventional gamma-ray camera systems are reduced. For example, the improved energy resolution allows better rejection of photons associated with Compton scattering events occurring in a source being imaged. This is because a narrower energy window filter can be used without rejecting a significant fraction of non-Compton scattered photons. The spectra processing component can be easily implemented with different types of gamma-ray imagers, for example Anger-type cameras, and may also be retroactively fitted to existing gamma-ray camera systems.

Title: Decoder capable of switching between turbo decoding mode and Viterbi decoding mode
Inventor: KUTZ GIDEON
IPC: H03M13/29
Filed: 2003-12-11
Abstract: A decoder is disclosed which can operate in a first mode for decoding a turbo encoded data stream and in a second mode for decoding a Viterbi encoded data stream. Upon receiving a first control signal (VIT START) the decoder stops decoding in the first mode, part way through a turbo code block, and switches to the second mode to decode a Viterbi encoded data stream. Upon receipt of a second control signal (TURBO CONT) the decoder switches back to the first mode to continue decoding the turbo encoded block from the point at which decoding was interrupted. Preferably the decoder will complete its current iteration before switching from the first mode to the second mode. The invention is particularly suited to wireless communications systems in which control channels are Viterbi encoded but data channels are turbo encoded.

Title: Antenna combining electric and magnetic fields
Inventor: NORMINGTON PETER
IPC: H01Q21/29
Filed: 2004-02-24
Abstract: The two components of an electromagnetic wave in free space or other dielectric media, can be generated separately and when combined in the correct ratio and in the correct phase and physical orientation, a real radiation resistance is observed at the terminals of the antenna. This patent application is the mathematics relating to forming the average of the two field systems over a given region in space and relating this to the basic problem of mixing electric and magnetic fields in the same region in space and equating the ratio of electric and magnetic fields to 120  f  to form an antenna. The fundamental problem is to control the relative field strengths, orientation, and relative phase of electric and magnetic fields with a single minimal conductive geometry which is simple enough to analyse. All theory herein is presented on the basis of taking the ratio of average electric to average magnetic fields in a common region in space and equating this the conjugate of the intrinsic impedance of the media through which the EM wave is traveling.
