Publication number: 20190133478Abstract: A method of using a magnetometer system (30) to analyse the magnetic field of a region of a subject's body is provided. The method comprises using one or more detectors (60) to detect the time varying magnetic field of a region of a subject's body, using a digitiser (42) to digitise a signal or signals from the one or more detectors (60), each signal that is digitised including noise and a periodic signal produced by one or more of the one or more detectors (60) due to the time varying magnetic field of the region of the subject's body, and averaging the digitised signal or signals over plural periods. The magnetometer system (30) is configured such that the noise in each signal provided to the digitiser for digitisation is greater than about 25% of the interval between digitisation levels of the digitiser (42).Type: ApplicationFiled: April 25, 2017Publication date: May 9, 2019Applicant: CREAVO MEDICAL TECHNOLOGIES LIMITEDInventors: Benjamin Thomas Hornsby Varcoe, David Diamante Dimambro, David Ian Watson, Richard Theodore Grant

Patent number: 9661377Abstract: There is provided an apparatus and a method for the receipt and processing of data signals carried in a plurality of predefined frequency bands and allowing a frequency band required at an instant of time to be selected from the predefined frequency bands from which data is to be retrieved. Passing the data signals from the wanted band to a transmitter and/or receiver including first and second mixing means to process the data signals, typically using in-phase and quadrative data feeds to create a predefined representation of the wanted frequency band, to provide an output for receipt by at least one broadcast data receiver and at least the transmitter and/or receiver is provided as part of an integrated circuit rather than as separate connected components.Type: GrantFiled: July 2, 2013Date of Patent: May 23, 2017Assignee: Global Invacom Ltd.Inventors: Gary Stafford, Graham Leach, Ian Watson

Publication number: 20080067532Abstract: A method of growing semiconductor materials in the Indium, Aluminium, Gallium Nitride (InAlGaN) material system and to devices made therefrom, in particular optical devices in the ultraviolet to green region of the visible spectrum. Certain optical devices, for example Vertical Cavity Surface Emitting Lasers (VCSELs) require great precision in the thickness of certain semiconductor layers. One aspect of the present invention provides a gallium-rich group III nitride layer (200, 201) and an adjacent layer of AlxInyGa1-x-yN layer (202). The AlxInyGa1-x-yN layer (202) acts as a fabrication facilitation layer and is selected to provide a good lattice match and high refractive index contrast with the gallium-rich group III nitride layer (200, 201). The high refractive index contrast permits in-situ optical monitoring. The extra layer (202) can be used as an etch marker or etch stop layer in subsequent processing and may be used in a lift-off process.Type: ApplicationFiled: November 4, 2005Publication date: March 20, 2008Inventors: Ian Watson, Martin Dawson, Erdan Gu, Robert Martin, Paul Edwards

Publication number: 20050005830Abstract: Indeterminate length fiber tows ends are joined by overlapping end portions of the first and second fiber tows. The first and second tows are secured in a clamp with a portion of the overlapping area exposed. The overlapping area of the tows is positioned on a sewing unit having a support and sewing head, at least one of which is displaceable along first and second axes, and a controller for executing a preprogrammed stitching pattern. The controller is actuated to form the preprogrammed stitching pattern in the exposed portion of the overlapping area, thereby splicing the first and second fiber tows.Type: ApplicationFiled: May 7, 2004Publication date: January 13, 2005Applicant: SOLUTIA INC.Inventors: Michael Dallas, Edd McGaric Ong, Francisco Abufele, Ian Watson

Patent number: 5150463Abstract: A data processing system comprises a number of processing nodes, each having a processor and a local store. The workload of the system is represented by packets, including function packets specifying a function and pointers to one or more argument packets to which the function is to be applied. When a node processes a function packet, it checks whether all its argument packets are resident in the local store. If not, copies of the argument packets are fetched from the remote nodes in which they reside. These argument packets are referenced by special indirection packets, which contain the local and global address of the argument packet, and a reference count for garbage collection purposes.Type: GrantFiled: August 22, 1989Date of Patent: September 22, 1992Assignee: International Computers LimitedInventors: Michael Ward, Ian Watson, Pak S. Wong

Patent number: 5021942Abstract: A data processing system is described in which the workload is divided into packets. A plurality of processors access the packets and process them by rewriting them according to predetermined rules. Packets can be of a number of different types, including XAPP and PAPP. An XAPP packet contains a function and one or more arguments in evaluated form, so that the function can be immediately applied to the arguements. A PAPP packet is similar except that its arguments may not be in evaluated form. Processing of an active PAPP packet consists of activating other packets which evaluate the arguments of the PAPP packet, and converting the PAPP to a suspended XAPP packet, awaiting return information from those other packets. The use of different packet types allows greater efficiency, by eliminating redundant actions in processing of the packets.Type: GrantFiled: June 23, 1988Date of Patent: June 4, 1991Assignee: International Computers LimitedInventors: Paul Watson, John V.
