Title: A superconducting magnet control system
Inventor: MALLETT MICHAEL JOHN DISNEY
IPC: H01F6/02
Filed: 2006-07-27
Abstract: A superconducting magnet control system comprises a plurality of magnet coils 11 - 18 each comprising superconductive material wound on a former. The magnet coils 11 - 18 may be energized to generate an operational magnetic field of predetermined strength and homogeneity. Each former also supports control windings 21 - 28 of a non-superconductive material. The control windings 21 - 28 are arranged to effect stable conditions in two or more of: the mechanical, magnetic and/or thermal behavior of the magnet coils during normal operation or quench. The control windings 21 - 28 may be formed by an over or under-binding layer of aluminium wire. Two or more of the control windings 21 - 28 may be interconnected in series and/or parallel arrangements. The control windings 21 - 28 may be connected across a subset of the magnet coils via a crossed diodes threshold circuit 36. The control system provides a simple, cheap, compact arrangement for dealing with a number of undesirable effects which may arise in magnetic resonance imaging MRI scanners.

Title: Visible light source with UV reflector
Inventor: CHUA JANET BEE YIN
IPC: H01L33/50
Filed: 2006-08-22
Abstract: A light source 200 capable of producing white light comprises a semiconductor radiation source 208, a thin film of phosphor 222 deposited over the surface of the radiation source 208, and a UV reflector 224. The radiation source 208 is preferably an ultraviolet ("UV") light emitting diode ("LED") that emits near-violet or ultraviolet light. The thin film of phosphor 222 absorbs UV radiation emitted by the source 208 and converts it to white light. The UV reflector 224 is optically coupled to the thin phosphor layer 222 so as to reflect UV radiation back to the phosphor layer while allowing visible light to pass through. Thus UV radiation is converted to visible light more effectively, and harmful UV radiation is prevented from being emitted from the source 200.

Title: Regularisation of irregularly sampled seismic data using sinc functions
Inventor: OZBEK ALI
IPC: G01V1/36
Filed: 2006-12-19
Abstract: A method of spatially shifting seismic signals acquired through a seismic survey comprises the steps of identifying within the signals a set of N actual locations of seismic receivers and corresponding N seismic signals received by the set of seismic receivers; identifying a set of N' desired locations of seismic receivers; and determining a set of N' signal values at said N' desired locations by evaluating for each of said N' signal values a weighted sum of the N seismic signals, wherein the weights are at least partly determined by evaluating a sinc function, or a mathematical equivalent of a sinc function, using pairs of locations selected from the set of N actual locations as argument. The weights may be at least partly determined by the relative distance between pairs of locations selected from said set of N actual locations of seismic receivers. The pairs may include pairs of locations which are not nearest neighbours.

Title: A signalling system to assist hard-of-hearing sports people
Inventor: SKELTON CHRIS
IPC: G08B23/00
Filed: 2007-03-05
Abstract: A system for assistance of hard-of-hearing sports people comprising one or more transmitters wherein one or more of the transmitters are integrated with a conventional audible signaling device such as a whistle and can signal by wireless on command, and one or more receivers which can be worn by players and can respond to transmissions from the transmitters by signaling to the players in a way they are able to perceive. The system can ensure full coverage of the playing area either by means of sufficient transmit power being available from the transmitter, by means of the use of repeaters around the ground, or as a mesh network where each receiver is able to retransmit any signals it receives for reception by other receivers. In addition the system can support team communication by means of separate transmitters available to coaches or managers, and potentially between the receivers themselves.

Title: Breast pump
Inventor: KAMPF CHRISTOPHER
IPC: A61M1/06
Filed: 2004-08-05
Abstract: Conventional breast pump systems use only a vacuum source as negative pressure to the breast to induce the expression of breast milk which can result in the elongation and distension of the nipple in an axial direction that is both uncomfortable and inefficient for the expression of breast milk. A breast pump according to the present invention comprises a pressure source which generates pressure during a pressure stroke the pressure source having a movable structure with a variable pressure volume or variable cycle time. In addition, the pump has a controller, operably connected to the pressure source, which regulates the pressure volume based upon a distance travelled by the movable structure or regulates the variable cycle time based upon a speed of the movable structure. The controller provides substantially real-time monitoring of the distance travelled or the speed.

Title: Determining appearance variations using chromophores
Inventor: COTTON SYMON D OYLY
IPC: A61B5/00
Filed: 2007-07-17
Abstract: An image of an individual 2 is obtained via a digital camera 1. The RGB image data is then processed to derive from the image data data representative of the distribution of chromophores resulting in the appearance of the individual 2. A calculated chromophore distribution is then utilised to derive a revised chromophore distribution representing the effect of the desired cosmetic or surgical intervention or medical condition. This chromophore distribution is then processed to generate an output image 34 illustrating the expected result of that intervention. The generated image 34 can be displayed simultaneously with an original image 33 so that the extent of expected improvement can be determined.

Abstract: 967,149. Phase detectors; amplitude modulation; valve frequency changing circuits. E. A. FAULKNER. March 14, 1963, No. 10128/63. Drawings to Specification. Headings H3A, H3F and H3R. In a phase detector or signal mixer one signal is applied to a thermionic valve having in its anode circuit two parallel connected thermionic valves whose grids are energized in push-pull from the anode circuits of two further thermionic valves to which the other signal is applied in push-pull from a phase splitter. Output in the form of rectangular waves is taken from one or both of two resistors in the anode circuits of the parallel connected valves which are switched on and off alternately. The circuit operates over a wide frequency range since all inter-valve couplings are purely resistive. Resistor potential dividersbias the standing grid potentials of the first and further two valves, and only resistors are included in their cathode circuits. All the valves may be triodes.
